Freeze Warning. The Freeze Watch has been upgraded 
to a Freeze Warning, which includes the immediate metro. Although the 
downtowns may avoid a frost/freeze, the suburbs probably won't. It's 
coming about 1-2 weeks ahead of schedule, if you're keeping track. The 
median date of the first 32 F. low at MSP is October 4. Details from 
NOAA:
...FREEZE WARNING TONIGHT INTO SUNDAY MORNING FOR ALL OF CENTRAL
AND SOUTHERN MINNESOTA AND WEST CENTRAL WISCONSIN...
.A FREEZE WARNING REMAINS IN EFFECT FROM 1 AM TO 8 AM SUNDAY
MORNING FOR ALL OF CENTRAL AND SOUTHERN MINNESOTA AND WEST CENTRAL
WISCONSIN.
LOWS SUNDAY MORNING WILL DROP INTO THE 25 TO 30 DEGREE RANGE OVER
MUCH OF THE AREA...RESULTING IN A HARD FREEZE FOR MANY LOCATIONS.
TEMPERATURES IN THE TWIN CITIES ARE EXPECTED TO BE A LITTLE
WARMER WITH LOWS NEAR 32 DEGREES. REMEMBER...FROST MAY BE
POSSIBLE EVEN IF TEMPERATURES REMAIN A FEW DEGREES ABOVE FREEZING.
THE COLD NIGHT AHEAD IS THE RESULT OF CANADIAN HIGH PRESSURE
MOVING IN. THIS WILL RESULT IN CLEAR SKIES AND NEARLY CALM
WINDS SUNDAY MORNING.
Coldest Since April 11. The last time the metro saw 
32 F. or colder? April 11 of this year, when we woke up to 27 F. It's 
been (well) above freezing ever since.

Weather Whiplash. I found it vaguely interesting 
that only one model is predicting a frost this morning; the vast 
majority show lows in the 33-40 range. But with clear skies, light winds
 and a dry, Canadian airmass, conditions seem ripe for frost, especially
 for outlying suburbs. By Monday afternoon temperatures may be 40 
degrees milder. Graph: Iowa State.
More Freeze Than Frost. A Freeze is defined as 3 
hours or more colder than 28, cold enough to kill off just about all 
plant life for the season. We may have those conditions 15-20 miles 
outside of the downtowns this morning. A freeze is likely from St. Cloud
 and Willmar to Mankato and Stillwater. The urban heat island may 
protect the downtowns and a few of the close-in suburbs from a 
widespread frost, but it's going to be close. Forecast temperatures

A Quiet Spell. A beautiful stretch of weather is on 
tap this week, highs mostly in the 60s, but 70s are likely Monday, again
 next weekend, the ECMWF (European) hinting at 80 by Monday of next 
week. A little rain is possible a week from today, but not the soaking 
we need.

Drought Timeline. NOAA's 
U.S. Drought Monitor shows the gradual progression and intensification of the drought covering much of the USA in this 
animation.
 The statistics are interesting: 70% of the lower 48 states are now 
described as "abnormall dry", moderate drought impacting 54% of the 
USA (up from 24% at the start of the water year). Severe drought is 
impacting over a third of America, up from 15.8% at the start of 2012.
Fire Danger. According to the 
Minnesota DNR
 the fire risk has been upgraded to "very high" over the Red River 
Valley. A high risk exists for most of central and southern Minnesota.
Autumn Forecast: You Might Not Need Heavy Coats For A While.
 Call me a contrarian. The venerable Farmer's Almanac is predicting 
"warmer and drier" for Minnesota and the Upper Midwest. So is CPC, the 
Climate Prediction Center. Based on recent trends and a brewing El Nino 
that forecast makes sense, logically. But the atmosphere hasn't been 
behaving logically in recent years - I'm pretty sure we'll have a colder
 winter than last, but not as severe or snowy as 2010-2011. At this 
point even an "average winter" would feel like the real thing. Here's an
 excerpt of a story at 
The Star Tribune: "
A
 warmer-than-normal autumn is likely for Minnesota, and may be  followed
 by another mild winter, a meteorologist from the National  Climate 
Prediction Center said Thursday. The agency released its latest 
three-month outlook, and  seasonal forecaster Huug van den Dool said the
 warm regime that's been  so pronounced across the hemisphere this year 
is likely to continue  through October, November and December in 
Minnesota and across the  United States. January through August of this 
year was the warmest such period on record for both the Twin Cities and 
Minnesota. As for winter, "I wouldn't go as far as saying it will be  as
 extreme as last year, but chances are it will be above normal," he  
said in a telephone conference with reporters. "That's the long-term  
trend." Photo above: AP.
3 Month Guess (Outlook). CPC, NOAA's 
Climate Prediction Center,
 is forecasting a milder-than-average October thru December for a huge 
chunk of the USA, drier than average for the Pacific Northwest, wetter 
across the Gulf coast and southeastern USA (which correlates with an El 
Nino warming over the central Pacific). Again, buyer beware. Odds favor a
 mild bias into at least the first half of winter, based on the trends 
of recent winters, but I sure wouldn't bet the farm on this. Call me 
perpetually paranoid, but what's happening in the Arctic (record 
melting) may have some blow-back across the lower 48. Hope I'm wrong.
Looking Ahead. Everyone wants to know what the 
winter will be like. Me too. Can you tell me where the NASDAQ will be in
 mid-February? Interest rates in early March? Looking at recent trends 
this winter should be milder than average, especially factoring in a 
mild to moderate El Nino warming, but that warming is taking place in 
the central Pacific, and in previous El Nino's like this the biggest 
impacts were over the Pacific Northwest and the southeastern USA, with 
little impact (cold or warm) on Minnesota and the Midwest. As I've been 
mentioning ad nauseum for days now, the Arctic is a huge wildcard. 
Record warming has created a semi-permanent bubble of warm high pressure
 at the top of the world, which may displace the cold "polar vortex" 
farther south, meaning more bitter swipes extending southward into the 
USA. The truth: models have some skill out to 15-20 days. Beyond that, 
forget about it. We can use ocean temperatures as cues, but there is 
still no reliable way to connect the dots and make a winter prediction 
with high confidence. Here is Mark Seeley's take in the latest 
installment of 
WeatherTalk: "
On
 Thursday of this week the NOAA Climate Prediction Center issued new  
seasonal climate outlooks.  The temperature outlook for Minnesota favors
  above normal values over the October-December period.  Actually this  
trend is seen for about 75 percent of the USA based on dynamical models 
 and past trends. Little emphasis is placed on El Nino at the moment  
because it remains in a neutral state.  The precipitation outlooks shows
  equal chances for above or below normal values over the  
October-December period across most of the USA except the southeastern  
and mid-Atlantic states which are expected to see above normal values."
Floods Bring Evacuations In Alaska Town. 
The New York Times has the story; here's an excerpt: "
ANCHORAGE (AP) — Residents of the Alaska tourist town of Talkeetna have been asked to leave because of the threat of flooding from the rain-swollen Talkeetna River....Gov.
 Sean Parnell toured the area around Talkeetna by helicopter on  Friday 
and landed to talk to some of the residents who fled their homes.  The 
governor declared a state disaster for the areas hit by the  flooding. 
Talkeetna, about 75 miles north of Anchorage, is the last stop for  
climbers heading to Mount McKinley. It also has an eclectic population  
and has long been purported to be the inspiration for the Alaska town in
  the 1990s television series “Northern Exposure.”

With Extreme Weather Will Insurers Come To The Rescue? Here's an excerpt of a timely story from meteorologist Andrew Freedman at 
Climate Central: "
Following
 a damaging episode of extreme weather, communities turn to  insurance 
companies to help them rebuild, but with costly extreme  weather and 
climate events on the rise as the climate continues to warm,  insurers 
may stop coming to the rescue, a new report warns. The report from Ceres,
  a nonprofit group that advocates for sustainable business practices,  
calls attention to the threat that extreme weather events pose to the  
sustainability of the insurance industry, which has been hit hard by  
record-breaking extreme weather in recent years, on top of lower profits
  due to other reasons."
Wildland Fires In Idaho. 
NASA has the details: "
One
 of the Expedition 33 crew members aboard the International Space  
Station, flying at an altitude of approximately 260 statute miles,  
recorded this nadir scene of the Mustang Complex wildland fires in  
Idaho. Close to 300,000 acres have been burned by the Mustang fires and 
 hundreds of people have been forced to flee the area."
"Ask Paul". Weather-related questions, comments (and reader explanations!)
Paul -  
I believe the DNR image
 of fall colors that you are seeing is a victim of too little data 
points. I'm not 100% certain, but I believe the map only uses the 
foliage reports out of the state parks. If you look at the state parks 
that are used across the metro areas, you can see that Ft. Snelling is 
the only park showing 50-75% color (and the only park within the metro 
area). Minnesota Valley State Park is showing 25-50%, Afton is showing 
10-25%, and Lake Maria is also showing 10-25% color. The result is a 
bulls-eye of 'color' over the Twin Cities. Similar to what happens when 
an erroneous temperature observation is indicated on a contoured map.  
Given
 so few data points and the likelihood of data smoothing issues, I'd be 
hesitant to make assumptions on the metrowide color being higher than 
most. I certainly haven't seen 50% color.

NASA Scientists Used Unmanned Aircraft To Spy On Hurricanes.
 Drone technology is here (to stay). Expect to see one over I-94 
providing real-time traffic reports within a couple of years. Why not? 
Wired Magazine
 has the story; here's an excerpt: "Hurricane researchers are gathering 
unprecedented data this month by  using two NASA Global Hawk unmanned 
aircraft. The airplanes were  originally developed for the military, but
 have been modified to aid in  atmospheric research. One of the Global 
Hawks was flown to its new base at NASA’s Wallops  Island Flight 
Facility on Virginia’s Atlantic coast earlier this month  and has 
already flown several missions over developing tropical storms  giving 
atmospheric scientists the ability to watch and measure storms  for up 
to three times as long as they could with manned aircraft,  including 
NASA’s modified U-2 spyplane. The second Global Hawk is set to depart the 
Dryden Flight Research Center in California and join its hangar mate in the next week or so." Photo credit above: NASA.
$20,000 Give To Girl For By AT&T For Creating Anti-Texting While Driving App. Coming to an smartphone near you soon; 
iPhone Informer has more details: "
$20,000
 has been given to a young girl by AT&T for creating an anti-texting
 while driving app. An 11-year old was awarded the prize  money as part 
of a hackathon last month. She created a concept mobile  app that aims 
to raise awareness for the “It Can Wait” campaign (via  iDB) The app is 
entitled Rode Dog and allows users to be placed into  “packs,” “with 
members of the pack able to check whether others are  texting whilst 
driving. If they are, remote users can set off an alarm –  a dog 
barking, oddly enough – in order to tell the offending texter to  stop.”
How To Stop Hospitals From Killing Us. If you read 
one article today make it this one. I know I'll be asking tougher 
questions the next time I check into a hospital for a procedure. The 
statistics are harrowing. Here's an excerpt from a 
Wall Street Journal story (subscription may be required for online access): "
When
 there is a plane crash in the U.S., even a minor one, it makes  
headlines. There is a thorough federal investigation, and the tragedy  
often yields important lessons for the aviation industry. Pilots and  
airlines thus learn how to do their jobs more safely. The world of 
American medicine is far  deadlier: Medical mistakes kill enough people 
each week to fill four  jumbo jets. But these mistakes go largely 
unnoticed by the world at  large, and the medical community rarely 
learns from them. The same  preventable mistakes are made over and over 
again, and patients are left  in the dark about which hospitals have 
significantly better (or worse)  safety records than their peers."
Flat Earth Society. Hey, I'm keeping an open mind. 
All those (millions) of images from satellites could have been faked, 
along with the moon landings, for that matter. Here's an excerpt of an 
FAQ from 
theflatearthsociety.org: "
"Q: "
Why do you believe the earth is flat?" 
A:  It looks that way up close. In our local reference frame, it 
 appears to take a flat shape, ignoring obvious hills and valleys. In  
addition, Samuel Rowbotham et al. performed a variety of experiments
  over a period of several years that show it must be flat. They are all
  explained in his book, which is linked at the top of this article."

iPhone 5 vs. Galaxy S III. It's getting nasty out 
there - have you seen the recent Samsung commercials poking fun at 
Apple's new iPhone? The knives are coming out - and I was interested to 
see what the tech-heads at 
gizmag.com had to say in a head-to-head comparison. Here is an excerpt of their review: "...
In
 2012, however, the biggest tech rivalry is the match between the  two 
biggest players in mobile: Apple and Samsung. This one has gotten  
nasty, extending into international courts. Things only get more interesting with the release of Apple's iPhone 5
 this week. A great product is much more than the sum of its parts, but –
 even in  this post-PC era – specs can matter. If one phone has a 
quad-core chip  with 2GB of RAM, and another a single-core CPU with 
128MB of RAM, the  first one will be much faster. Likewise, a display 
with 320 pixels per  inch (ppi) will look much sharper than one with 
163ppi. You'd be foolish  to worship at the altar of specs, but 
technical details can still shed  some light on the subject."
"Fox And Friends" Corrects Claim About Obama's Pirate Meeting (Well Sort Of). Journalism guru 
Jim Romenesko has the (crazy details). No, you can't make this stuff up. “
Fox
 and Friends” on Thursday used the Obama and pirate shot on the  right 
to show that the president is more interested in meeting with a  pirate 
than in conducting foreign policy. The AP’s David Bauder reports: "Over 
 an on-screen graphic that said “Arrrgh You Kidding?”, Fox ran the  
picture Thursday morning with host Brian Kilmeade saying, “The White  
House doesn’t have the time to meet with the prime minister of Israel,  
but this pirate got a sit-down in the Oval Office yesterday.”
             
Indian Summer Alert
Sadly, many Minnesota plants froze their buds 
off last night. Frost came early to many towns and suburbs - the average
 date of the first 32F at MSP is October 4. We're waking up to the 
chilliest morning since April 11 (27F).
But look at the bright side: a frost/freeze 
killed off much of the ragweed. Allergy sufferers will be breathing 
easier in the weeks to come. And now that we've had a frost - we can 
(officially) call tomorrow's mid-70s Indian Summer.
Because we want to be official.
It's been a weather-whiplash kind of year. 
Drought and low lake water levels in April gave way to torrential rains 
in June with historic floods in Duluth. And then we went over another 
rainfall cliff. Maybe it's always been this way, but our fast-forward 
weather pattern has meteorologists shaking their troubled little heads.
Welcome to one of the 5 driest Minnesota 
Septembers since the late 1800s, and I don't see any significant rain 
looking out 2 weeks. We are stuck in a dry, dusty rut.
Jackets for church this morning, then shorts Monday as 70s return.
Great weather lingers; long-range guidance 
hinting at 80F about 8 days from now. Then again 5" rain would qualify 
as great weather.
Climate Stories...
Climate Change And Extreme Weather. Here's an excerpt of an article at 
HealthNewsDigest.com that caught my eye: "...
While
 most scientists don’t dispute the link  between global warming and 
extreme weather, the once skeptical public is  now starting to come 
around—especially following 2011, when floods,  droughts, heat waves and
 tornadoes took a heavy toll on the U.S.  According to a poll conducted 
by researchers at Yale University’s  Project on Climate Change 
Communication, four out of five Americans  reported personally 
experiencing one or more types of extreme weather or  a natural disaster
 in 2011, while more than a third were personally  harmed either a great
 deal or a moderate amount by one or more of these  events. And a large 
majority of Americans believe that global warming  made several high 
profile extreme weather events worse, including record  high summer 
temperatures nationwide, droughts in Texas and Oklahoma,  catastrophic 
Mississippi River flooding, Hurricane Irene and an  unusually warm 
winter."
Time For The GOP To Get Serious About Climate Change, The New National Security Issue. Here's a snippet from an interesting read at 
The Atlantic: "
....This
 is not a "soft" issue that should be of concern only to  
environmentalists. Climate change can be destabilizing in international 
 affairs, a fact that the Department of Defense is now trumpeting. As 
the  2010 Quadrennial Defense Review Report notes,
  climate change contributes to food and water scarcity, provoking or  
exacerbating mass migrations, and amping up conflicts over resources.  
The report states, "While climate change alone does not cause conflict, 
 it may act as an accelerant of instability or conflict, placing a 
burden  to respond on civilian institutions and militaries around the 
world."

Despite Little Mention Of Climate Change From Candidates, Faith Groups Pledge To Make It A Campaign Issue. Here's an excerpt of a post from 
Think Progress: "
This week, the National Climate Summit 2013 Coalition released a petition
 calling on both Presidential candidates to address rapidly accelerating
 climate change. The statement, written and endorsed by over 1300 faith 
leaders,  elected officials, civil rights groups, environmental 
activists,  business representatives, and others, calls on both 
Presidential  candidates to “act in the best interests of this and all 
future  generations of American’s now by publicly acknowledging the 
climate  emergency”; and committing to host a climate summit to craft 
actions for  national solutions within their first 100 days in office."
What Is The True Social Cost Of Carbon? Here's a clip from an interesting article at 
Living Green Magazine: "...
Potential greenhouse gas policy, post-November, remains a murky picture. While candidate Mitt Romney has said he opposes a carbon tax, some of his economic advisers embrace the idea
 (subscription) as a means to tackle greenhouse gas emissions, 
especially in tight fiscal times. The Washington Post’s Ezra Klein 
frames the carbon pricing debate as a bargain between Democrats and Republicans, and a Slate piece offers that carbon taxes are good not only for the environment, but also for the treasury.
 Meanwhile, Daveed Gartenstein-Ross argues in The Atlantic that, given 
the national-security challenges the issue poses for the U.S., Romney 
and the Republican party are “ceding important ground by tolerating and encouraging denialism” of climate change. Ralph Nader says Obama and the Democrats are “running away from the issue” of climate change."
Got Science? Not At News Corporation. Here's an excerpt of a story at 
The Union of Concerned Scientists: " 
In
 2007, News Corporation CEO Rupert Murdoch claimed coverage of  climate 
change in his media outlets — which include Fox News Channel and  the 
Wall Street Journal opinion pages — would improve over time. Such 
improvement has not been achieved. A 2012 snapshot analysis  shows that 
recent coverage of climate science in both outlets has been  
overwhelmingly misleading. The analysis finds that the misleading 
citations include broad  dismissals of human-caused climate change, 
rejections of climate science  as a body of knowledge, and disparaging 
comments about individual  scientists. Furthermore, much of this 
coverage denigrated climate  science by either promoting distrust in 
scientists and scientific  institutions or placing acceptance of climate
 change in an ideological,  rather than fact-based, context."
PBS Ombud: NewsHour Climate Change Report Worth Criticizing. Here's a clip from 
Media Matters for America: "
A PBS NewsHour global warming report that allowed a climate change contrarian to "counterbalance" mainstream scientific opinion is
  worth criticizing, according to PBS Ombudsman Michael Getler, who said
  he received hundreds of emails and calls about the program. Getler 
said he is penning a column on the issue that is likely to be  posted 
late today or Monday, and hinted it will be critical. "There's just a 
lot of...hundreds of emails about it," Getler said  when asked why he is
 writing about the issue. "Commentary about it all  over and it's 
interesting." Getler declined to offer specific views on the NewsHour 
report, which  aired last Monday. But when asked if he has found 
elements to  criticize, he said: "Oh yeah, of course there's material to
 be critical  about."
Climate Change Could Awaken Canadian Forests: Study. 
The Toronto Sun has the story; here's a clip: "
Ancient
 forests in Canada's North could one day bloom again, thanks to climate 
change, a new study has found. Bylot Island in Nunavut is home to a 
fossilized forest that  scientists estimate is between two and three 
million years old. Once  upon a time, the North's cold and barren 
landscape featured a lush  forest of oak, pine, spruce and hickory. If 
temperatures in the North continue their upward climb, that forest  
could return within a century, Alexandre Guertin-Pasquier of the  
University of Montreal says. "According to the data model, climate 
conditions on Bylot Island will  be able to support the kinds of trees 
we find in the fossilized forest  that currently exist there, such as 
willow, pine and spruce. I've also  found evidence of a possible growth 
of oak and hickory near the study  site during this period," 
Guertin-Pasquier said in a press release."

How Green Was My Lawn. What happened to environmentalism? The idealism of the 1960s and 1970s has worn thin. Here is an excerpt of an Op-Ed at 
The New York Times that caught my eye: "....
Today,
 however, climate change, perhaps the most important environmental  
issue of our time, rarely polls among voters’ top five concerns. One  
reason may be that its patently global character has enervated support  
at environmentalism’s suburban grass roots. But it doesn’t help that  
blanket condemnation of suburbs as hopelessly dependent on fossil fuels 
 comes all too easily."
