.SHORT TERM...Tonight and Thursday
Afternoon water vapor imagery shows a developing upper-low across
central Idaho this afternoon. With this, seeing some areas of snow
showers mainly across the Arco Desert and upper Snake Plain this
afternoon. As the afternoon progresses, activity will continue to
push south and west as the low moves quickly to our south. Could see
some very light snowfall accumulations with these showers but
shouldn`t be anything overly impactful. A few tenths is most likely
with perhaps up to an inch with the heaviest and longest lasting
activity. Things should quickly quiet down overnight with all the hi-
res models clearing out basically regionwide. The lone exception may
be across the South Hills and down towards Malad where maybe a few
snow showers linger into late morning tomorrow. On Thursday our
streak of pleasant weather will begin as skies clear and temps start
to warm. No impactful weather is anticipated tomorrow and this will
continue for some time. A taste of spring is coming! McKaughan

.LONG TERM...Friday through next Wednesday.
A fairly classic text-book style Rex Block pattern sets up over the
Western US on Friday with strong low parked over the Southwest and
high pressure sitting over the PNW. This will give us a break from
the active weather as we wrap up the week and head into the weekend
with temperatures continuing to warm. Highs will be in the 40s to low
50s for most by Friday afternoon with 50s to low 60s through early
next week, though the low 60s look confined to the Magic Valley at
this point. By Monday morning, lows could stay above freezing for
most of our lower elevation areas. We will have to keep a close eye
on how this will impact snow melt and any potential for flooding. At
least it looks like we will continue a nice, gradual snow melt up
until that point. Models show the ridge breaking down Tuesday into
Wednesday, which could open the door back up for active weather in
the second half of next week.

.AVIATION...18Z Wednesday through 18Z Thursday.
Snow showers will continue on and off at most sites through the
evening as a low drops south through eastern Idaho today. When
snow passes over a terminal, expect VIS and CIG drops to MVFR and
IFR conditions. Even outside of snow at the terminals, conditions
are generally borderline VFR/MVFR due to low CIGs. Breezy
conditions will continue at BYI, PIH, and IDA into the early
evening with a short break overnight before returning again on
Thursday with gusts in the 20 to 30kt range. Precip is expected to
wrap up from north to south this evening with it all ending
by/just shortly after 06Z. Then we get to enjoy a stretch of much
quieter weather. AMM
