DISCUSSION. The trough of low pressure is currently over the Northern Rockies causing numerous showers. These showers are producing a variety of precipitation types from light to moderate rainfall, graupel and even snow in higher terrain. These showers will persist throughout the night and slowly taper off during the day on Monday as the upper level flow becomes northwesterly. The higher terrain along the Continental Divide down through southwest Montana and into Lemhi county will experience some light snow accumulations, but impacts to region should be minimal.
Temperatures on Monday will continue to be 10 to 15 degrees below normal for this time of year. Then clearing skies Monday night into Tuesday should allow temperatures to drop dramatically, similar to what was experienced last Friday morning. If you still have sensitive plants or vulnerable above ground irrigation, you might want to take protective measures.
A ridge of high pressure quickly builds over the Northern Rockies on Tuesday causing a warming and drying trend. Then on Wednesday a disturbance will flatten the ridge causing increased winds during the afternoon and evening. At this time little to no precipitation is anticipated with this feature.
A building ridge becomes the dominant feature for the Northern Rockies for the remainder of the work week into the weekend. Temperatures will be steadily warming with Saturday being the warmest day. Another disturbance could impact the region on Sunday, but confidence is very low on timing and strength.
AVIATION. Showers will continue to impact terminals through the area. These showers could cause visibility to be reduced to IFR for periods of time. Snow levels appear to lower to around 6000 feet by Monday morning causing snow in the higher terrain. Expect mountains and passes to be obscured at times.
