.SHORT TERM /THROUGH TONIGHT/...
Issued at 102 AM MST Wed Dec 10 2025

AR moves north today. As a result, qpf amounts through
12Z thursday are generally 0.25 inches or less and mainly confined
to the upper terrain. Snow levels rise to above 8000 feet today and
temperatures are warmer. We should see a gradual clearing this
morning into the afternoon. Communities in the mountains and
highlands will mostly see highs today in the mid and upper 40s while
the Snake Plain and eastern Magic Valley will see highs in the 50s.
Idaho Falls will approach a record high today. The record is 52 set
in 1993. Pocatello would really have to overachieve to reach their
record of 63 in 1939. Winds don`t look as strong as yesterday but
still rather gusty. Probably looking at a 20-40 percent chance of
reaching advisory levels on the sustained wind. The Arco Desert and
INL are much more likely of seeing sustained 25 with gusts to 45 mph
today.

.LONG TERM /THURSDAY THROUGH TUESDAY/...
Issued at 1236 PM MST Tue Dec 9 2025

Once again the long term period Thursday through next Tuesday is
dominated by extremely warm and mainly dry conditions.  High
temperatures for the most part will range from the upper 30s to mid
40s mountains and upper 40s to mid 50s lower elevations.  Thursday
and Friday will be the warmest with some upper 50s in the low
elevations.  Lows generally 20s and 30s throughout.  The general
average forecast through the period is around 15 to as much
as 20 degrees above normal.   Upper ridge slides west to east
Thursday through Saturday and will be overhead Saturday.  Will see
only slight cooling when the ridge moves east Sunday through
Tuesday.  Will have mainly dry conditions Thursday through Sunday
with only a slight chance of mountain showers.  A more zonal pattern
may allow a better chance of precipiation  Monday into Tuesday as a
return to Pacific moisture is in play.  Have some chances everywhere
by Tuesday with still very elevated snow levels at over 6 thousand
feet.

.AVIATION /18Z TAFS THROUGH 18Z THURSDAY/...
Issued at 1058 AM MST Wed Dec 10 2025

Breezy conditions continue this morning at KPIH, KIDA and KDIJ
and this is expected to remain in place for the duration of the
TAF period. Winds 15-20 kts are likely in these areas with
higher gusts, perhaps lessening slightly overnight. KSUN and
KBYI will see winds more around 10 kts or so. Expect BKN
mid/level CIGs to continue through the period with some
occasional SCT/BKN lower clouds in the 2-4kft range that could
cause some brief reductions to MVFR but generally expecting VFR
to prevail through the period. KDIJ could see some occasional
showers but otherwise, terminals are expected to be dry.
