DISCUSSION
Most of the precipitation has moved to our west as of 9:30am MST. Another system will move in this evening through tomorrow morning, with breezy westerly winds expected mainly in south central Idaho. Snow levels will lower to valley floors tonight, with a light dusting of snow expected in the Boise metro area early tomorrow morning. Weak instability aloft could support a graupel showers in the valleys with brief heavier snow showers in the mountains this evening. Forecast appears to be on track, no updates necessary.
AVIATION
Isolated MVFR/IFR showers this morning. Then numerous showers this afternoon and evening. Some showers may produce LIFR conditions with heavy snow and graupel this afternoon and evening.

PREV DISCUSSION
SHORT TERM
Today through Saturday night
A shortwave trough will exit to our east this morning as a second trough and cold front arrive from the west this afternoon. Rain and snow showers will briefly taper off this morning before increasing again with the front. Temperatures will be around 10 degrees cooler than yesterday, but still 5-10 degrees above normal. Snow levels will hover around 4000 feet today with rain in the lower elevations. Winds today will be gusty, strongest across southeast Oregon and south of the Snake Basin in Idaho where gusts to 40 mph are possible. The cold front will reach the Treasure Valley late this afternoon and the Magic Valley by late evening, with gusts to 30 mph and showers accompanying the front. Rain may turn to snow along the front in the Magic Valley, but the front is expected to move out before snow levels fall below 3000 feet in the Treasure Valley.
Light snow showers could linger into Friday as a weak impulse rotates around the backside of the trough. This will bring a 40% chance of snow (less than 1") to the Treasure Valley. The Magic Valley has a 90% chance to see at least a dusting of snow tonight through Friday, with a 20% chance of 1" or more.
Mountain valleys look to pick up 2-5" of snow, with an additional 6-12" of snow above 6000 feet today through Friday.
Winds will be gusty on Friday as the trough exits to our east, strongest across south-central Idaho (including the Magic Valley) where gusts 35-45 mph will develop. Temperatures on Friday will drop another 5-10 degrees from Thursday.
An upper level ridge will briefly move overhead Friday night and Saturday. Mostly clear skies and subsiding winds Friday night will allow for cold overnight lows. Clouds will increase on Saturday as the next system approaches our area. A chance of snow will develop Saturday night, but most of the moisture is now favored to remain to our north until Sunday.
LONG TERM
Sunday through Thursday
The chance for rain/snow will continue into Sunday as a shortwave trough tracks across the region. Additional snowfall in the mountains will be light, generally less than 2 inches, with lesser amounts in the valleys Sunday morning. Lower elevations will see a change to rain as snow levels rise to 3500-5500 feet on Sunday. A second trough will drop down the front side of an amplifying ridge on Monday, keeping a chance of showers across the region but adding very little in way of additional rain or snow accumulation. The upper ridge folds over the Pac NW Tuesday as the exiting low cuts off over the Desert SW. The ridge will bring dry conditions for Tue/Wed before a slight chance (10-20%) of snow showers returns to the mountains Thursday. Temperatures are near normal through the period.
