Good news! After days of warm weather, it's cooling off this weekend

Treasure Valley Extended Forecast
Posted at 3:48 AM, Jun 14, 2024

After a warm Friday afternoon, a cold front is approaching the Treasure Valley which will bring the chance for very isolated showers and thunderstorms. Moisture will be limited with these thunderstorms, but watch for lightning and gusty winds later this evening and overnight.

The bigger story is going to be a substantial cooldown arriving for the weekend. Temperatures will drop into the low to mid 70s, with overnight lows dipping into the 40s – the coolest air so far this month.

The wind picks up behind the frontal passage tonight and 30-40mph gusts are possible on Saturday for locations east of Boise. Isolated showers and thunderstorms are still a possibility north of McCall, but the Treasure Valley stays dry throughout the weekend.

Pack layers if you are planning on camping in the mountains this weekend as nighttime temperatures will dip into the upper 20s and lower 30s with daytime highs reaching the upper 50s and lower 60s.

By early next week, a cold low pressure system will push into northern Idaho, bringing unseasonably chilly air and mountain snowfall. Several inches of snow may accumulate above 7000 feet by Tuesday morning.

If you were enjoying the summer heat, don't worry, the cool spell will be short-lived. We warm right back up to summer-like temperatures just in time for the official start of summer (next Thursday at 2:51pm MDT).
