March Snow Marches On

March Snow Marches On

By Todd Nelson

I have an itch that a scratch won't reach right now. If you planned a warm spring break vacation at any point over the next couple of weeks, I think you planned accordingly. By the way, if you have a spare ticket that you need to get rid of, I'm available! I don't know about you, but I could use a nice sunny, 70° day right about now to shake off the winter willies.

Last year on "Pi Day" (March 14th = 3/14; Mathematical "Pi" = 3.14), the mercury soared to 73° (our 4th record high temperature recorded in March 2012). This year, we get spat on by a quick moving clipper system that will kick out an AM wintry mix and perhaps a light coating of snow across central and northern Minnesota. The second wave of energy slides in on Friday with another shot of wintry precipitation. That Friday wave may be a little more substantial and drop a few inches of slop for some across central and northern Minnesota again. Your commute times AM Thursday and PM Friday could be a little slow.

If that's not enough, plow potential is increasing for us as a storm looks to develop PM Sunday thru AM Tuesday... UGH! It's not too late to book that flight, but take me with! -Todd Nelson

Todd's CONSERVATION MN Outlook for the Twin Cities and all of Minnesota:

THURSDAY: AM wintry mix, commute time could be a little slower. Light coating of snow for central and northern MN. High: 36. Winds: SW 5-10

THURSDAY NIGHT: A little clearing. Low: 26

FRIDAY: More robust clipper drops in from Canada. Rain/snow mix possible. A few inches of slop possible for central and northern MN. High: 35.

SATURDAY: Feeling cooler. Passing flake. Low: 16. High: 28

SUNDAY: Developing storm, snow late. Low: 12. High : 28

MONDAY: Don't put away the shovels just yet. Low: 19. High: 29.

TUESDAY: Lingering light snow/flurries. Low: 10. High: 25.

WEDNESDAY : A break in the wintry action. Low: 8. High: 25

One-Two Punch
A quick moving clipper system will impact the area two different waves through the end of the week. The first punch will move through late Wednesday/early Thursday with a little wintry mix (including a little light freezing drizzle potential). The second and a little more substantial wave will move through Friday. The result will be some light shoveling duties for folks across central and northern MN and WI. On the southern edge of this snow, there will once again be a little freezing rain/drizzle potential. The graphic below suggests the snowfall potential thru AM Saturday.

Snow Depth Comparison
Take a look at the National Snow Depth comparison from 2013 to 2012. Thanks to a remarkable warm March 2012, very little national snowpack was still visible. Winter is still hanging on this year and we may add to that snowpack yet into the coming days.

Remembering March 2012
I don't know about you, but I could go for a nice warm day right about now. Unfortunately, Mother Nature was a litte goofed up last year. Not only did we have a number of record high temperatures, but there were reports of magnolia trees in full bloom as well!

Twin Cities March 2012 Sample
Here is just a sample of what we experienced last March. Look at the stretch of record highs! WOW!! The meteogram below shows temperatures in 2012 vs. 2013 (including 2013 forecast highs thru the 19th). All the numbers from 2012 with an "R" appended to it was a record for that date.

Remembering the 1993 "Storm of the Century"
From March 12th-14, 1993 - a massive winter storm wrapped up across the eastern part of the country with massive snow totals, exceeding 40" in some cases!

"What started out as an area of low pressure off the coast of Texas on March 12, 1993 quickly developed into what many people refer to as "The Storm of the Century." The evolution of this winter superstorm can be seen in this imagery from the GOES-7 satellite, using both visible and colorized infrared data. As the storm developed in the Deep South, it spawned 11 tornadoes in Florida and dumped from 8 to 33 inches of snow from Alabama to the Carolinas. As the storm moved north and intensified, conditions became even worse. With a central pressure of 960 millibars, usually found only in Category 2 hurricanes, whiteout conditions were common. Snowfall exceeded 3.5 feet in some locations.
When the storm passed, 208 people were dead and $6.6 billion dollars in damage were sustained. The National Climatic Data Center still ranks the 1993 as the most (­s) impactful winter storm to hit the Northeast. Though the 1978 and 1996 blizzards may have brought more intense localized conditions, the scale of the 1996 storm has not been equaled in recent history."

1993 Incredible Snowfall Tallies
There were some incredible snowfall tallies from that storm! A number of spots picked up over 30", but how about 16.2" from Atlanta, GA. Here are some images from the storm back then.

"Described as one of the largest and most intense storms in a century, the March 12-14,1993 blizzard paralyzed the eastern seaboard with record cold, snow, and wind. Southern cities not accustomed to severe winter weather like Birmingham, Alabama, Atlanta, Georgia, and Chattanooga, Tennessee were buried by paralyzing snows and frozen by unseasonable cold. The severe cold following the storm preserved much of the snow, prolonging travel nightmares for a couple days over the south where most roads were never plowed. The combined effects of high wind and heavy wet snow downed thousands of miles of power lines leaving millions of people in the dark for up to a week in some cases over the south. The above photo was taken right after the storm. Albany resident Dave O'Connor digs out his car on upper Madison Street."

Are You Done With Winter?
We asked another question on Facebook wheather or not you're done with winter!? There were several good responses, here are a few.


Winter Not Giving Up Just Yet?

Extended model runs are still hinting at yet a little more substantial snow event late weekend/early next week across parts of the Upper Mississippi Valley and Great Lakes Region. Consistency in the ECMWF (European model) has been fairly good in recent days, which is helping with the growing confidence level of this potential event. Stay tuned for further updates!

Long Range Maximum National Snow Depth Forecast
This is a little interesing. Here's a long range (10-day) model forecast of possible maximum snow depth across the nation. Note how far south this snow could be. Winter may not just yet!
March 14th = "Pi Day"
Don't forget that March 14th = 3/14 is "Pi" day, which mathematically is 3.14! So, happy Pi Day!
Calculating Pi With Real Pies!
In honor of "Pi Day" - I thought this video was neat... Also note that the length of the video is 3mins and 14secs - LOL!

"How accurately can we calculate Pi using hundreds of REAL pies?"
