.SHORT TERM...Today through Friday...Snow levels this morning
will drop to around 5000 ft across the Snake Plain and the Central
Mountains and around 5500-6000 ft in the Eastern Highlands. Expect
snow showers to persist this morning and afternoon for the
Mountains across the Eastern Highlands. An additional snowfall
accumulation of 1/2 inch or less is forecast with a few isolated
areas potentially seeing close to an inch. A mix of rain/snow is
forecast for a small portion of the Upper Snake Plain including
Ashton and St. Anthony. Temperatures today will be a few degrees
warmer than yesterdays, though similar, with drier air filtering
in from the west. The dry air will be accompanied by cooler air
leading to some fairly chilly overnight temperatures. Lows tonight
will be below the freezing mark in the mid to upper 20s for
Southeast Idaho. Lows across the Eastern Highlands will be in the
upper teens. We`ll watch for possible fog development overnight
as well as skies will clear and winds may be light enough.

Thursday and Friday will be under the influence of building high
pressure. Warming air will bring temperatures up into the 60s by
Friday. Skies will be free from precipitation with diurnal wind
variations. NP/Valle

.LONG TERM...Saturday through Wednesday.

A system will pass north of the region on Saturday which means the
weekend should remain dry. A big system will develop off the Pacific
Northwest coast for next week. This system will send moisture and
cooler temperatures into the area for the first half of the week.
Central Idaho mountains and eastern Idaho highlands stand the best
chance for showers with only a slight chance for the Magic Valley
and Snake Plain for now. Snow levels will be coming down during the
week as well. Snow levels will begin the week around 8000 feet but
will fall to around 6000 feet by Wednesday.



.AVIATION...Expect to see improving conditions across the region
today as a system departs. May see some lower ceilings and possibly
some light snow around Driggs this morning. But even there,
conditions should improve by afternoon.
