Mountain valleys started the month of May with a fresh coating of snowfall. Brundage Mountain received 2 inches of snowfall (6,050 feet) overnight into Wednesday morning. Across the lower valleys, it feels like an early spring day with a brisk northwest breeze and temperatures ranging from the mid-40s in the Magic Valley to the lower 50s in the Treasure Valley. The Magic Valley will struggle to touch 50° this afternoon.

A low-pressure center is moving into northwest Montana as of this afternoon, and some wrap-around moisture continues to impact the central mountains. Thus, a few spotty showers are possible through sunset. The weather pattern remains active as another system will bring a round of hit-or-miss showers and thunderstorms to the area on Thursday. Temperatures will remain cool, with mid to upper 50s in the valleys and mid to upper 40s in the mountains.

Sunshine returns and temperatures warm just in time for Friday. High temperatures will be around average in the mid-60s with plentiful sunshine. A strengthening storm system off the Pacific Northwest coast will place Idaho under strong southwest flow, resulting in warmer temperatures on Saturday. Highs will climb into the lower 70s in the Treasure Valley.

A cold front arrives Saturday evening, bringing rain showers, gusty winds, and a dramatic cooldown into Sunday. Temperatures will return to the 50s in the valleys and 30s and 40s in the mountains. This system is set to bring substantial moisture to the mountains, with moderate to heavy snowfall expected above 7000 feet. There is a possibility of snow showers in the Boise foothills.
