3/19: 1ST Day of Spring & SNOW Chances

LAST Day of Winter came to a close and what a 'chilly' way to end it; for some of us. Here are the Highs from Tuesday:
Casper: 40°
Buffalo/Gillette: 31°
Sheridan: 35°
Douglas: 43°

BUT...SPRING is here and will arrive Early Wednesday at 5:03 AM Mountain Daylight Time... Here's a great graphic showing you the Equinox

TEMPERATURES will Warm Up in the Lower to Middle 50°s for many of us in Central & Eastern WY on Wednesday. Here is the 4PM Temps from the RPM Model for tomorrow.

SNOW will Arrive on Wednesday for West of the Divide... So let me discuss this Snow Chance and then our Thursday Chances tomorrow night.

--This shows the Probability of 8" or GREATER thru Thursday Night..including Wednesday's Snowfall.

As you can see, the Tetons/Jackson Hole/YNP/ Gros Ventres mountains could likely see the Heaviest Snow Potential





That being said, here is what the Snow Amount could look like:

--This is based on the 95th Percentile through  Thursday Night.  Tetons/Jackson could wound up getting over a Foot in the Lighter Blue and most of Western WY will likely see 6-12" in many spots.  
AS this system spill Eastward up to 1/2 Foot for Bighorns possibly.   Central WY in the Lower Elevations could be in the 1-4" Range...Rough Estimate, but a better grip on the Models will be on Wednesday.
