11/12: "Semi" Unsettled Week to NEW Weekend Storm ~ SNOW?

Not a bad Afternoon as we saw Temperatures well above Average as Southwest Winds increased as we'll likely see another Balmy/Breezy Wednesday.  Here are Today's Highs across Wyoming.

I did say "Semi" Unsettled, right?  Well I think Wednesday looks to remain Dry and Warm/Breezy, but a small, weak wave of energy (Shortwave) could slide in for late Evening. ALL Models show the feature sliding in.  GFS/NAM keep the storm through Northern WY/Montana with Light Snow keeping much of Central & Southeast WY dry, but the EURO model is a touch Different.

<< EURO by 11PM Wednesday shows Northwest Flow with a Trough sliding through.  Drop of the Temperatures are expected, but this is very 'light' amount of Moisture.

THOUGHTS:  I think many will stay Dry, right now, as the Mountains could see some Moisture or Light Snow





As for THURSDAY,  We'll stay Cool & Dry once the Front passes.  Again the word "SEMI" Unsettled comes into play again.  Now its the NAM Model that shows something weak in nature.  EURO/GFS stay dry, but NAM brings a weak Shortwave in the Central Rockies in Colorado drifting North.

<< NAM wants to Linger this System for Friday morning along I-80 and Cheyenne area with Light Snow but this is very weak at this time.  










WEEKEND STORM:  Now the Afternoon on Saturday looks Dry and Cool but things could change fast to end the Evening as we roll into Sunday. What we are tracking is a Cool Front dropping from British Columbia to Montana and Wyoming.  A Surface Low will then form from UT into Colorado as the Front and Low Converges together.  Timing/Intensity/ & Storm Track is still hard to pinpoint as Both the EURO/GFS show different signs.  Here is what the Storms 'could' look like by Sunday Morning:

<< GFS shows a Large 996mb Low in Eastern CO providing Moderate/Upslope Snow in Central WY.  Great placement of snow for CASPER. 











<< EURO Model shows a very strong and deep Low at 992mb along I-70 in CO/KS.  

* Note how SNOW is now in West-Central Colorado with the Low and leaving only Light Snow/Flurries in Wyoming.  

* PLUS, the Front is Colder than the GFS Model which could dry out the Snow & Moisture.  




EARLY THOUGHTS:  Like I said, there are so many Variables yet to know for sure.  This is a Dynamic storm will have the potential to impact WYOMING.  Cool & Wet conditions are likely but How Much, When it starts, and Who will see the Heaviest Snow is still hard to factor in. Stay Tuned as some will see Accumulation out of this Storm.
