.SHORT TERM /THROUGH THURSDAY/...
Issued at 124 PM MDT Wed May 14 2025
Upper level trof has shifted east with strong northwest flow
aloft continuing to bring in very cold conditions with well
below normal temperatures continuing through Thursday. Wrap
around moisture with the system passing east will produce

snow levels 7 thousand to 7500 feet. Lows tonight will be in the
20 sand 30s mountains and 30s to around 40 valleys. Will remain
in a cool northwesterly low aloft Thursday with showers

.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
Issued at 124 PM MDT Wed May 14 2025
Guidance solutions in this period are coming together
on the first feature that barrels through the western states. There
is almost no difference except in the low intensity through Tue. So
Fri through Mon will be wet and cold as the incoming upper level
trough deepens into a closed low and stays over until Mon. Partial
drying out develops Tue.
The southerly wind ahead of the upper low keeps a warming trend
going into Sat. The trough is south of the forecast area but on our
longitudes by Sun afternoon. Cold air floods in as the air flow
becomes northerly, pushing highs to 15-20 deg F below normal. It
won`t be until Tue that temperatures return to just slightly below
normal.
Winds continue to track strong to very strong during this period,
both at night and during the day. Strongest wind Sun afternoon
evening with the upper trough passage.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 606 PM MDT Wed May 14 2025

aloft is still bringing light showers and/or vicinity showers

KIDA, KPIH and KBYI could see brief MVFR CIGs early tomorrow
