A WINTER STORM WATCH has been issued for elevations above 5000' in western and southwest Montana.
After a wild weekend of wind and a wildfire south of Helena, Monday was a pretty pleasant day. That will change on Tuesday and for the rest of the week, as the final week of spring will be wet, cool, and wintry in some locations. A deep dip in the jet stream will allow a cold, late spring storm to produce significant rain in the lower elevations and significant mountain snow. This could be the last storm of its kind for a while. Nonetheless, Tuesday will be a cloudy day with showers, thunderstorms and periods of rain in central and western areas. Highs will range from the 50s west to the 70s farther east. Wednesday will be the coldest, wettest and snowiest day. Rain will be widespread with snow falling in the mountains. The higher elevations will have highs in the 30s and 40s, with the lower elevations in the 40s and 50s. Thursday will still be unsettled with cool temperatures and widespread showers. Friday is the final day of spring and there will still be scattered showers although more sunshine will prevail. Saturday is the first day of summer and the new season will arrive right on time. With mostly sunny skies, highs will warm into the 70s and low 80s. Sunday is Father's Day, and the weather will be even warmer with highs in the 80s. More typical warmth and dry weather will continue for the first week of summer.
Have a great day.
