High pressure over the West will be sending in a drier WNW flow over the Northern Rockies allowing for sunshine to continue thru the 4th of July! By the end of the holiday weekend however, more moisture will begin to creep in thanks to split flow over the Rockies, meaning afternoon thunderstorms will occur.
Tonight, skies staying mostly clear allowing temps to drop into the 40's and 50's yet again for a crisp cool morning!
Fourth of July will be the hottest day with a mix of sun and clouds. Highs in the Snake River Plain will be into the upper 90's. A few pop-up thunderstorms are possible in the Southern Highlands and Central Mountains but most of us staying dry. Breezy conditions especially during the afternoon and early evening with winds around 15-20mph from the SW.
Cooler temps for Sunday with mostly cloudy skies and widespread afternoon and evening thunderstorms across the region. Highs into the upper 80's.
