.SHORT TERM...Tonight and Monday
It`s a beautiful late winter Sunday across eastern Idaho as high
pressure remains in control of local weather. Afternoon satellite
imagery is generally void of clouds although a few very high cirrus
clouds are seen streaking quickly across the region from time to
time. Temperatures have warmed nicely into the 40s and 50s across
many of the lower valleys where snowpack has already melted. Areas
with a bit of snow remaining, like the upper Snake Plain, are still
running in the upper 30s and lower 40s despite the ample sunshine.
No concern for precipitation tonight although some patchy fog and/or
stratus COULD be realized around Bear Lake and around Idaho Falls
into the INL. The high pressure ridge will be flattened slightly
tomorrow as a weak shortwave moves to our north. This will bring a
slight increase of winds to the area as well as a bit more cloud
cover but temperatures will continue to run on the warmer side of
normal. Can`t rule out a very isolated shower in the central
mountains tomorrow afternoon/evening but hi-res models aren`t overly
excited with this potential so it appears most locations should
remain dry.

.LONG TERM...Tuesday through next Sunday.
The next upper trough will move onshore Wednesday, with
precipitation overspreading Southeast Idaho Wednesday evening and
overnight into Thursday. Temperatures will initially be too warm to
support snow in our valleys, with widespread above-freezing lows and
snow levels above 5,500 feet areawide. Snow levels will drop to
valley floors by late Thursday behind the cold front as daytime
temperatures drop back into the 40s and cooler and lows return to
sub-freezing areawide. Current 72-hour QPF totals through Saturday
range 0.25" to 0.50" across our valleys with 0.75" to over 1" in the
mountains. Models show a very brief break in activity late Friday
into Saturday as the low departs to the east and the next low
approaches the coast. This system will move onshore early next week
with models showing widespread snow beginning Sunday. Cropp
