.SHORT TERM...Today through Friday night...Gradual warming and drying
through Friday as the main upper trough over the interior northwest
US slowly weakens. Scattered snow showers over the mountains today,
and again Thursday in the central Idaho mountains but fewer than
today. Still enough instability for isolated thunderstorms over
the mountains late today and again late Thursday. High temps will
increase about two degrees per day while lows hold generally steady.
Winds will be northwest through Friday 5 to 15 mph in the nights
and mornings, 10 to 20 mph in the afternoons, except 20 mph with
afternoon gusts to 35 mph in the Snake Basin east of Boise.

.LONG TERM...Saturday through Wednesday...An upper level ridge
is expected to build across the northwest region through Saturday,
continuing a warm and dry trend over the weekend with daytime
temperatures in the 60s and 70s across the valleys, and snow
levels in the 5000-6000 ft range over the entire area. A
shortwave trough is expected to move into the region on Monday,
slightly cooling temperatures and bringing showers and chance
of thunderstorms Monday afternoon/evening. Snow levels will be
expected to rise to 6000-7000 ft range, and snowfall is
generally not expected over the area early next week. Following
this brief trough passage, a longwave ridge is expected to move
into the area through Tuesday and Wednesday, returning above
normal temperatures and drier conditions until the end of the
extended forecast period.
