Lou Holtz once said "“Never tell your problems to anyone...20% don't care and the other 80% are glad you have them.” That stuck with me over the years. Take the weather. Please!
People tell me "It's too hot, too humid, too cold, too wet, too dry, too windy or too sunny!" A long list.
Wake me up when it's just right.
Abe Lincoln nailed it when he too complained about not being able to please all the people all of the time. He got that right.
Four month ago I stood too close to the Doppler and in a feverish rant predicted a cooler, stormier, wetter than average summer. It's sort of working out that way, after all.
Yesterday's highly unusual July cut-off low is pinwheeling east; warming temperatures aloft will mean more stable atmosphere. Plan on pudgy afternoon cumulus, and after a chilly start we mellow above 70F with less wind. Still a little cool for the lake, but a more soothing balm for Minnesotans fretting about summer heat slipping away.
80s return by midweek - but I see a cool bias looking out the next 2 weeks. Is the hottest weather of summer behind us? Probably.
Wednesday and Friday look stormy, but next weekend will be better; highs in the 70s. Fewer jackets, scowls & grumpy weather-complaints, I pray.
If You Don't Laugh You'll Weep. I took one look at this map, screen-captured Saturday afternoon in the Twin Cities, and I wanted to weep, or scream, or hurl. Or all of the above. Hey, it was one ill-timed, nearly historic, Saturday July cold front. Courtesy: WeatherNation TV.
Saturday Highs. The coolest daytime maxes were north/east of the Twin Cities, some mid-50s close to Duluth. Highs were milder farther west, nudging 70 over western counties, farther away from the cut-off low, where the sun was out part of the day. Map: MesoWest.
Coolest Since 1997. Unusual? Yes. Unprecedented? Probably not. According to NOAA records the last time Minneapolis - St. Paul saw July temperatures as cool as 49F. was 1997.
Mellowing Out. Temperatures struggle to near 70F today with morning sun giving way to a mix of clouds and sun by afternoon, less wind and drama than yesterday. Highs nudge 80F by midweek, the best chance of showers and heavier T-storms Friday. Next weekend? It has to be better/drier/milder. Right? ECMWF forecast hghs above in Celsius.
Late September In Late July. A buckling jet stream pours near-record chill into the USA, some of the coolest July temperatures in a decade from the Upper Midwest to the Great Lakes, the cool front weakening slightly by the time it reaches New England. Dorian has weakened into a tropical wave, but the NAM model shows a potential tropical storm approaching the Bahamas by Wednesday.

7). The National Weather Service defines summer warnings using:
8). Who got their start as TV weather broadcasters?
a). Diane Sawyer
b). David Letterman
c). Pat Sajak
2). Answer: (a). Dew point is an absolute value, unlike relative humidity not dependent on the air temperature.
3). Answer: (c). Yes, fog is a lazy stratus cloud, one that forms on the ground.
4). Answer: (b) (c). Solar flares can disrupt radio communications and GPS, sparking dazzling displays of the Northern Lights. Especially strong X-class solar flares can even bring down portions of the power grid.
5). Answer: (b). To be considered severe a thunderstorm needs to produce 58 mph+ winds and/or 1" diameter (quarter size) hail.
6). Answer: (b).
7). Answer: (c). Local National Weather Service offices no longer issue warnings for entire counties, but portions of counties, using a polygon to define the "high threat area", the actual track of a tornado or severe storm.
8). Answer: (a) (b) (c). Pat Sajak was a Los Angeles weathercaster, David Letterman reported weather in Indianapolis, where he coined the expression "hail the size of canned hams") and yes, Diane Sawyer got her start reporting and pointing at weather maps.

"So for a few days, our weather is being influenced by “Canadian Air” as meteorologists around here and probably across the country refer to it as. My question is, do Canadian meteorologists refer to air invading from the south as “American Air”?

• The incidence of high-intensity tropical cyclones (Safir-Simpson categories 3-5) should increase, and the amount of rainfall in these storms should increase, upping the potential for freshwater flooding. These changes will not necessarily occur where tropical cyclones develop and thrive today. "Indeed," wrote Emanuel, "it is likely that there will be decreasing activity in some places, and increasing activity in others; models do not agree on such regional changes."
• Though experts disagree on this point, Emanuel's work suggests that weak events (tropical storms and Cat 1-2 storms) will become more frequent.
• "Very little work has been done on the problem of storm size," wrote Emanuel, "what little research has been done suggests that storm diameters may increase with global temperature. This can have a profound influence on storm surges, which are the biggest killers in tropical cyclone disasters..."
