Snow on Vancouver Island
Thanks
to my Aunt Sylvia for these pictures at Qualcom Beach on Vancouver
Island. She's an avid golfer, so this is putting a wrench in her golf
game. She says that winter has arrived!
Arctic Plunge
Thanks
to the University of Maine for the image below, which shows the
temperature anomaly for Monday, February 24th and note the big blog of
deep blue/purple from the much of North America nosing into the eastern
two-thirds of the nation. Interestingly, according to the stats below,
even though we were much colder closer to home, the globe as a whole was
+0.33F above norm.
Cold Meteorological Winter
Keep
in mind that meteorological winter stretches through the three coldest
months on average for the northern hemisphere (December, January and
February) The image below shows the temperature anomaly for that time
frame over the northern hemisphere. Note how cold that time period was
for a large chunk of the continent.
Signs of Spring
Thanks
to my good friend Stephanie Trindade for this picture out of Las Vegas,
NV. I think she's just trying to rub it in, but nice to see some signs
of spring no matter where it is located! Hopefully it won't be too long
for this to take place it other areas of the country!
SELFIE
Not
sure if you've heard of the new catchphrase "Selfie" or not, but this
one is great! It's a Squirrel Selfie! Thanks the Zion National Park for
this:

More Signs of Spring
Here's an amazing timelapse of storms. It's definitely worth a look!

produced a new time-lapse video called "Stormscapes.""

Weather Outlook
The
weather outlook through PM Thursday shows a little light snow from the
midsection of the nation transitioning into a little more rain potential
across the southeastern U.S. and more snow for the northeastern part of
the U.S. - also note the heavier moisture moving into California at the
end of the loop!
Snowfall Potential
Thanks
to WeatherBell Analytics for the image below, which shows the GFS snow
potential through PM Friday. Other than some light snow chances across
the eastern two-thirds of the nation, the biggest threat for heavy snow
appears to be in the higher elevations in the western U.S.
Precipitation Outlook
I
am most intrigued by the recent outcome in the precipitation department
for the western U.S. and especially across California over the next 7
days. Although this rain won't be a drought busting event, it will
certainly help! According to NOAA's HPC 7 day precipitation forecast, some
areas in California could see +5" by early next week!
Much Needed Rain
Here are the details on the rain chances this week from the NWS in Oxnard, CA:
...Two Storm Systems to Bring the Most Significant Rains of the Winter...
TIMING
Storm #1 - Wednesday afternoon/evening through midday Thursday.
Storm #2 - Friday morning through Saturday
CONFIDENCE
High
confidence on timing; moderate on rain amounts. Computer model data has
been very consistent with the storm tracks since last Thursday, Feb.
20, therefore, forecasts have not deviated.
MAIN IMPACTS
Storm
#1 - This is the weakest storm. No significant impacts outside of the
typical slick roadways and minor clogged storm drains are expected
Wednesday afternoon through midday Thursday.
Storm #2 - This is
the strongest storm of two. Main impacts will be the potential for
heavy downpours in and near thunderstorms. This could lead to mud and
debris flows near recent burn scars (Colby, Madison, Springs), and urban
flooding of roadways and drainage systems Friday through Saturday. Snow
accumulations above 5000 feet on Saturday could lead to road closures
or chains required on vehicles. In addition, gusty winds to 50 mph in
the mountains could result in reduced visibilities due to fog and/or
blowing snow.
AMOUNTS
Storm #1 - 0.25-0.75” in most areas with upwards of 1” for the Santa Ynez and San Gabriel Mountain slopes.
Storm
#2 - Widespread 1-2” for coasts and valleys and 2-4” with locally 6”
for mountains. Locally heavier rainfall totals can be expected due to
the showery nature of the event lingering on Saturday.
SYNOPSIS
Two
storm systems in one week will be the first of it’s kind this winter.
Storm #1 will be ordinary with minimal impacts expected late Wednesday
through midday Thursday. Storm #2 will be much stronger bringing greater
impacts Friday through Saturday. We will be monitoring this system
closely due to the potential for thunderstorms with heavy rain. Brief
downpours could create mud and debris flows near recent burn scars along
with urban flood problems due to clogged drainage systems.
It is
likely that we will see higher rainfall amounts from these two storms
than we have received in total going back to July 1st. Even with the
significant rains expected, we would need 5-7 equivalent storms in March
and April to get back to a “normal” rainfall season."
Huntington Beach, California
Take
a look at this stunning webcam view from Monday afternoon from
Huntington Beach, California. This webcam will likely look much
different later this week as much needed precipitation heads into the
region.

Drought Comparison
It
has been extremely dry across the western half of the country for a
number of weeks and months. Here's the difference in the drought from
February 2013 to February 2014. Note the at this time last year, the
biggest drought was across the Plains. While there is still some
significant drought in the Plains, the worst has shifted into the
western U.S.
