PREV DISCUSSION... /issued 120 PM MDT Wed Sep 21 2022/

SHORT TERM...tonight through Thursday night.

Upper low over northern California will move into eastern Oregon
tonight before arriving in western Montana on Thursday. Central
and eastern Idaho is under a favorable area for severe
thunderstorms with over 50kts of 0-6km shear present over the
region. Main severe threat includes large hail and damaging winds,
an isolated tornado due to interaction with the terrain is
possible but not likely because of weak low level shear. A severe
thunderstorms watch is in effect for most of central and east
Idaho into the early evening hours. A cold front will march
through the area this evening, with cooler more stable air
filtering into the region. HREF shows rounds of showers and
thunderstorms moving from southwest to northeast through the
night. Showers and thunderstorms will be possible through the day
tomorrow, mainly across the high country. Storms are moving rather
quickly which will limit the flooding threat, however, given
precipitable water values of greater than 0.75" some heavy
downpours are possible. As these storms advance into the upper
Snake highlands, we expect the rainfall totals to mount through
the night and into Thursday. Rainfall totals of 0.1-0.5" inches
are likely most areas with 0.7-1.5" possible across the greater
Island Park/Driggs areas. Rainfall amounts may vary greatly
depending upon which areas see storms tonight.

13

LONG TERM...Friday through Wednesday
The extended forecast is looking warm and dry for the most part.
Ridging starts to build back in on Friday and strengthens throughout
the weekend and early next week. We will still be a bit breezy on
Friday as the closed low continues farther north an east with gusts
around 15-25 kts. As the ridge strengthens, our temperatures will
warm into the upper 70s and low 80s by Sunday and stay above average
for this time of the year at least into midweek. Generally speaking,
record highs next week are in the low to mid 80s, so we will be back
in record-high territory with our afternoon highs Monday through
Wednesday. The higher elevations will see highs in the mid to upper
70s. There is a bit of disagreement between the GFS and ECMWF on
timing, but both models show a weak shortwave working its way
through during the late Tuesday/Wednesday time frame. This would
help flatten the ridge a bit ahead of the next potential system
arriving at the end of next week. As that system is outside of the
forecast period and over a week away, there are plenty of
uncertainties with it and for now is just something to watch as
models evolve over the next week. AMM

AVIATION...18Z Wednesday - 18Z Thursday
Expect showers and thunderstorms through the afternoon, evening, and
overnight into Thursday. Conditions look to stay overall VFR, but
CIGs/VIS will approach and could drop to MVFR when storms pass over
terminals. These storms could produce some good downpours,
lightning, and gusty winds. Some storms could be severe, producing
60+ mph gusts. Outside of storms, gusts around 20-25 kts will be
possible, though gusts from outflow boundaries could be stronger.
While the bulk of the widespread activity looks to wrap up around
12Z Thursday, spotty showers will continue through Thursday before
we dry out completely by Friday morning. AMM

FIRE WEATHER...A low pressure system and associated cold front
will work through the region tonight. Many areas will see showers
and thunderstorms with widespread wetting rains likely. Isolated
to scattered showers with isolated thunderstorms are possible
Thursday. Gusty winds are likely as well on Thursday with gusts of
20-25 mph possible..
