12/26: MORE Light Snow for Thursday

Good Wednesday Evening, everyone.

It was good to see Snow on Christmas eve and even day after Christmas.  This LOW developed Tuesday in ID and dropped some good amounts and now coming here in WY.  Along with it, a Frontal Boundary is draped from MT and South in CO.

But here is the Current Position of the LOW Pressure with the Radar.

The LOW is just South and East of Casper and will continue with the Northerly Flow .  Snow is not shown, but it is evident when you walk outside...providing the 'ground truth' of the Radar image.  Some have seen over 2" with light snow continuing to fall.

A New Low or 'shortwave' will slide in from MT and drape through WY tomorrow evening around 5PM.  This will continue our Snow chances.  Not a "Heavy" snow, but just enough to cause slick spots.  So travel safely.

Here is the HI-RES RAPID REFRESH (HRRR) I like to use when I "Now-Cast" and this shows the Accumulated Snowfall through 11AM Thursday.  Not a large amount of snow, but Casper Mtn and Ten Sleep and Black Hills. could get up to 2-3".  However, Casper and Buffalo/Sheridan could see up to 1-2" additional snowfall.  Note that 'donut hole' in Platte Co?  Some dry air could intrude for SE WY.  Majority of the Snow will remain in the Sierra Madre's and Snowy Ranges.
