DISCUSSION
KEY MESSAGES:
- Isolated to scattered showers across southwest Montana, Lemhi County and north central Idaho through Friday.
- Breezy easterly winds Thursday into Friday, causing choppy water on area lakes.
- Gradual warming trend continues into Saturday.
- Cooler with more widespread precipitation likely Sunday into Monday.
Shower activity will remain in place across the southern half of western Montana and north central Idaho (generally along and south of Interstate 90) through Friday. Showers will likely become a bit more widespread in these areas Thursday as a low circulation tracks along the southern Montana/ID/WY borders. Precipitation will taper off significantly to the north, especially across northwest Montana.
All areas will see breezy easterly winds develop beginning late tonight and lasting into Friday morning. Widespread gusts 20 to 30 mph will be common, with exposed terrain in northwest Montana seeing gusts up to 35 mph, especially in the evening timeframe on Thursday. Those with outdoor sensitivity to wind may want to monitor the forecast, as well as outdoor recreationalists on area lakes due to expected choppy water conditions.
Overall, temperatures will be trending upwards through Saturday, with many locations seeing their warmest temperatures of the week Saturday afternoon. Shower activity will begin to increase Saturday afternoon across north central Idaho and southwest Montana ahead of an approaching trough of low pressure.
For the most part, forecast models have continued to trend further south with the main low pressure system for Sunday into Monday.
While wet, showery and cooler conditions look likely, the scenarios showing a very wet system are becoming less likely (15 to 20 percent chance). In fact, locations near the northwest Montana/Idaho panhandle border may see very little in the way of precipitation. The higher terrain of southwest Montana and north central Idaho will likely see some snow showers down to roughly 6000 feet by Monday, however impacts down to mountain pass levels look minimal at this time.
There is growing confidence in high pressure building into the region by mid next week. While the details of this ridge are still somewhat in question, there is a growing chance for a more prolonged dry and warm period by mid to late next week.
AVIATION
Surface observations this afternoon reveals a surface low across extreme southwest Montana and southeast Idaho. Given this low, a northerly gradient will remain in place through this evening, with sustained northerly winds of 5-10kts with occasional gusts of 15-20kts across north-south orientated valleys through 24/0300Z.
Isolated showers will develop across Lemhi County Idaho in the vicinity of this low from 23/2000Z to 24/0500Z.
