....Rockies...
Days 1-2...

Positively-tilted trough over the northern Rockies this morning
with a vort lobe over the Bitterroots will drift south through
Thursday. Focus for precip is along a surface boundary ahead of the
upper trough axis with light to moderate rates over WY today and CO
tonight Thursday. Snow levels will be elevated - around 8000ft
in WY and 9000ft in CO. Day 1 snow probs for >6" are around 30% in
the southern Absarokas/Wind River and 40-60% over the Bighorns. Day
1.5 snow probs for >6" are 40-70% through the Front Range and the
Mosquito Range.


The probability of any freezing rain across CONUS is less than
10%.
