Evening storms and a cool Friday
SEVERE THUNDERSTORM WATCH through 11 p.m. for Flathead, Lake, Powell, Glacier, Pondera, and Teton counties as well as the Helena, Great Falls, and Havre areas. Storms will produce lighting and periods of heavy rain and gusty winds. Hail could develop with the strongest cells this afternoon. The most likely area for a severe storm to develop today stretches from eastern Granite County north to eastern Flathead County and east to Great Falls, Helena, and Havre. Storms will primarily impact areas north of I-90 in western Montana after 5 p.m. The most severe storms later tonight will likely develop from Great Falls north to the Canada border between Havre and the east side of Glacier National Park. Stay alert for any severe weather warnings on-air and on our mobile apps.
Conditions will be considerably cooler Friday afternoon after an uneventful night and early morning in the upper 40s and low 50s. Showers hanging around the Continental Divide will develop into scattered showers and storms in the afternoon roughly from MIssoula to Butte and stretching east towards Lewistown. These storms are highly unlikely to become severe, although breezy conditions and some small hail will be possible along with isolated lightning strikes. Kalispell and Bozeman should see less activity Friday afternoon, particularly Kalispell. Highs will only be in the 60s with low 70s in Bozeman.
Expect unsettled weather this weekend with a chance for showers both Saturday and Sunday. Temperatures will remain in the 60s with lows in the 40s.
Any showers this weekend will be appetizers to the main course as a moist system reaches our area late Monday and sticks around through most of Tuesday. Expect this to be a soggy period with moderate to heavy rain and even a little snow above 6000 to 7000 feet in the mountains. Conditions will dry out Wednesday.
