First Alert Forecast: Showers and thunderstorms

RED FLAG WARNING until midnight for Glacier National Park, the Flathead Reservation, and the Flathead, Kootenai, Lolo, Bitterroot, Clearwater and Nez Perce National forests. 

Temperatures will be a few degrees cooler today, but still very hot with highs in the upper 80s and 90s. A large Pacific storm is sitting off the coast of British Columbia. Energy and moisture will rotate into the area, bringing an increasing chance of showers and storms.  Some afternoon and evening storms could be strong with gusty winds, small hail and lightning.

Moderate to heavy rain will impact the region as our Pacific storm tracks across the west.  An area of widespread rain is possible across northwest Montana.  Rainfall of one to two inches will be possible in and near Glacier National Park.  Areas north of I-90 will see the possibility of a half to one inch of rain, with lighter amounts from the Bitterroot east to the Butte and Bozeman areas.  Temperatures will be rain cooled with highs dropping to the 70s to around 80 on Friday.

Once the storm moves northeast into Canada, a warming trend is expected by early next week, with highs warming back to the 80s.
