A humbling storm
By Paul Douglas
My
wife is right - I should have my head examined. Peering into an
unknowable future and attempting to pinpoint weather at a given time
& place is a daily lesson in humility.
On
this date in 1940 the Twin Cities were digging out from 16 inches of
snow; 20 foot drifts out west. A paralyzing blizzard, one that wasn't
predicted. 145 people died, 49 in Minnesota; mostly duck hunters
stranded along the Mississippi. We went from 60s to blinding, horizontal
snows in a matter of hours, catching everyone off guard.
In
1940 government forecasts were originating in Chicago. Since then local
offices have opened up in the Twin Cities; we now have computer models,
weather satellites and a constellation of Doppler radars. Could it
happen again? The odds are less, but not zero. There will still be
events where we shake our heads, where technology only goes so far.
This is as cold as it gets this week, temperatures thawing to 50F over the weekend. Rain is likely late Saturday and Sunday AM.
Another
surge of numbing, Canadian air sparks a colder storm next Monday.
Accumulating snow is possible Monday night into Tuesday, followed by
eye-watering windchill. Something to look forward to.

2000:
A winter storm system produced a narrow band of heavy snow across
extreme western Minnesota. Winds toward the end of the event were
clocked between 15 and 25 mph, throwing additional snow into the air
resulting in reduced visibilities of 1 to 1.5 miles. Some snow totals
included: Canby (Yellow Medicine County) with 6.5 inches, Madison (Lac
Qui Parle County) with 6.0 inches.
1940: Record low highs were set
in west central Minnesota. Alexandria had a high of 8 degrees
Fahrenheit, Springfield and Willmar had highs of 10 degrees, and St.
Cloud and Minneapolis had highs of 11 degrees.
1933: Duststorm hits Southwest Minnesota, while a blizzard rages in the Northwest.
Minneapolis Temperature Outlook
Super Typhoon Haiyan
It
has been a few days since Super Typhoon Haiyan blew through the
Philippines, but the damage is extensive. The concerns is that the death
toll from Haiyan could top 10,000 over time.
Super Typhoon Haiyan Continued...
The
estimated sustained winds associated with Haiyan were nearly 200mph
with gusts up to 235mph. Satellite estimations are used in the West
Pacific, while aircraft are used in the Atlantic basin and give a more
accurate depiction of the storm. However, with that said, this could
likely be the strongest hurricane/typhoon to ever make landfall.
The Size of Haiyan
I
thought this was interesting. The size of Haiyan compared to the Gulf
of Mexico is shown below. Haiyan takes up nearly the entire area! Also
note how big Katrina was in 2005 and how much bigger Haiyan really was!
HELP!
There are a number of different ways you can help. A number of different organizations are excepting donations/etc.
Here's how you can help:
Armistice Day Blizzard of 1940
November
is typically known as an active month weather-wise as big storm systems
wrap up across the midsection of the nation. With increasingly longer
nights and a growing snow pack, the cold air mass is building across the
far north. This increase in temperature gradient from north to south
tends to whip up "Gales of November" storms. Once such system developed
on Armistice Day back in 1940!

Cold and Snowy
Our
current Arctic front is nothing like the Armistice Day Blizzard of
1940, but it's getting a few peoples attention. We've seen snow from Calgary, Canada to the Midwest and Great Lakes Region. Here was a
picture from a good friend of mine, Michelle Surgeson out of Calgary,
Canada.
U.S. Snow Pack
According
to NOAA's NOHRSC, 11% of the nation was covered in snow, but only those
along the extreme northern fringe of the nation and those in the
mountains in the west. Note how much of the southern tier of Canada
appears to be snow covered, this is certainly helping to keep the air
chilled up there.
Cold Temps
Here
were the actual low temps reported AM Monday across the prairie
provinces of Canada. Note the near -20° low temps reported as this
Arctic air mass oozed south into the lower 48.
One
thing to keep in mind is that there is very little snow on the ground
across the Lower 48, so as the cold air sinks south, the air mass will
moderate. Sure it'll be cold, but not as cold as what we've seen in
Canada due to the lack of snow! Thanks goodness!! In the graphics below,
note how the integrity of the cold begins to weaken over time. Again,
it'll be some of the coldest air of the season for folks east of the
Rockies, but it won't be as cold as what we had in Canada.
Forecast Lows AM Tuesday
Forecast Lows AM Wednesday
Great Lakes Snow
The
lake effect snow machines are kicking into gear again. Because of our
current cold air mass, lake effect snows will continue through Tuesday
and add up to 6"+ in a few spots downwind of the Great Lakes.
Snow Potential
The
Arctic front will still squeeze out some snow in spots across the Ohio
Valley and Appalachians through Tuesday. Other than that, it doesn't
appear that there will be any SIGNIFICANT snowfalls across the nation
within the next few days.
Looking Ahead/More Cold
Here's
a look at the temperature trend from week to week. Our current Arctic
air mass looks to plunge as far south as the Gulf Coast States by
Tuesday with frost and freeze likely. However, we do get a little wedge
of warmth to replace this chill by the end of the week. Looking ahead,
weather models are hinting at another cold front by early next week...
Keep those jackets handy, it is November after all
