.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 212 PM MDT Mon Apr 14 2025

It`s a beautiful Spring day across eastern as high pressure is
in full control of the weather. Afternoon visible satellite
imagery is completely void of any noticeable clouds throughout
the area and temperatures have warmed nicely into the 50s
throughout much of the area. Lower valleys will likely top out
in the low to mid 60s before the afternoon is up. The ridge will
amplify further overnight and into the day Tuesday allowing for
even warmer weather tomorrow where low 70s will be commonplace
in the lower valleys with low to mid 60s across the high
country. Once again, clouds will be hard to come by through the
morning hours but will begin to increase somewhat as we get into
the afternoon but still expecting more sun than clouds. Just a
sign of some of the changes in store for the area by the time we
get to midweek.

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Issued at 212 PM MDT Mon Apr 14 2025

Wednesday is a transition day with split trough moving in from
Pacific. Moisture pools across East Idaho ahead of trough Wednesday
afternoon and evening, with showers possible mainly over higher
elevations. Models are coming into better agreement with progression
of the split trough over the interior west through Thursday, but
there is still some 50% of the ensembles that want to close the
northern stream low somewhere over the Great Basin. These solutions
are also a tad bit colder than the competing 50% of the ensembles,
which progress the trough southeast a little quicker without closing
it off, and are a little warmer with the ridge trying to build back
behind the departing trough. Thus still not a lot of confidence yet
in how system is expected to play out over East Idaho, but the means
portray Thursday as wettest overall. The means also drop most of the
precipitation south before temperatures cool off enough to bring
snow to valley floors. Northerly gradient on Thursday looks to be
robust, with potential for a low-end Wind Advisory already painted
in the means across the Arco Desert zone. A few showers linger
across the southeast corner into Friday in potential wrap-around
region associated with trough/low sagging through Great Basin. Of
all higher elevation zones with snowfall potential, Bear River Range
MIGHT be closest to needing a mid-high elevation Winter Weather
Advisory for accumulations, as that region would be maximized both
ahead of and behind the trough through Friday. Still far too early
with too much uncertainty to lean one way or the other.

Reprieve behind this system is short lived as series of progressive
shortwaves impacts PacNW and East Idaho through Monday. Temperatures
rebound slightly into the weekend and early next week, but not
significantly so. Showers return to the region by Sunday afternoon.

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...

no aviation impacts at all. Will see normal diurnal wind
variations at SUN and will likely see upvalley afternoon winds
after 18Z returning to PIH and IDA with southwest 5 to 10 knot
winds.
