DISCUSSION
KEY MESSAGES:
- Localized frost Thursday morning, mainly south of the I-90 corridor.
- Breezy with scattered showers Friday-Saturday, focused on western Montana (Glacier Region) while Idaho stays dry.
- Warm up early next week.
Breezy conditions are developing today with widespread 15 to 25 mph, and 15 to 35 mph in southwest MT. Isolated showers or thunderstorms will be possible in north-central ID, Lemhi County ID, and southwest MT this afternoon. A stronger shower or storm will be capable of wind gusts up to 45 mph.
Thursday morning with sufficient cloud clearing, areas of frost will be possible, especially higher valleys of north-central ID and southwest MT along with Lemhi County ID where a frost advisory has been issued.
The region remains in northwest flow Friday as another system drops south out of Canada. While temperatures will only cool slightly, shower chances return, primarily across western Montana, while north-central Idaho remains generally dry. The most widespread showers and isolated thunderstorms will focus over the Glacier Region. Rainfall amounts appear light, with NBM averages generally under 0.10 inches in the valleys, though up to 0.50 inches is possible across the higher terrain of Glacier. Breezy conditions will persist, with afternoon gusts reaching 20 to 25 mph each day.
Looking into early next week, ensemble clusters strongly favor an unseasonably strong high pressure ridge building along the West Coast. This pattern will bring dry conditions and a significant warming trend, with temperatures climbing into the lower 80s for western Montana valleys and the lower 90s in north-central Idaho.
The only exception to the dry weather will be a few isolated showers along the Continental Divide.
AVIATION
Moist northwest flow will maintain periodic showers today. While VFR conditions will generally prevail, brief MVFR ceiling and visibility reductions and mountain obscurations are possible within heavier showers. Widespread westerly wind gusts of 20-25 kt will develop by late morning, with localized gusts up to 40 kt possible near stronger convective showers. A slight chance (<20%) of thunderstorms exists this afternoon, primarily from north-central Idaho southeastward into southwest Montana. Showers and winds will diminish after sunset with partial clearing overnight. Patchy valley fog may develop early this morning near KSMN, with localized valley fog potential across north-central Idaho and northwest Montana Thursday morning.
