Get ready for a chilly Monday night as the coldest temperatures in a few weeks are expected across southwest Idaho!

Lows Tonight

The core of an unseasonably cold low-pressure system is slowly making its way across central Idaho, triggering showers, thunderstorms, and mountain snow. Through the remainder of the evening, hit-or-miss showers and thunderstorms will continue to track across the Treasure Valley, accompanied by small hail, heavy downpours, and gusty winds.

Winds subside tonight as temperatures drop into the 30s and 40s. A Frost Advisory is in effect from 2:00 AM to 9:00 AM Tuesday for eastern sections of the Magic Valley. Temperatures could drop as low as 32°, so make sure to cover any sensitive outdoor plants before you head off to bed tonight!

A few leftover showers are possible in the mountains on Tuesday, but skies will clear as the system pulls away. A quick return to summer heat is expected, with temperatures jumping into the 70s on Tuesday and then reaching the 80s on Wednesday.

Summer officially kicks off at 2:51 pm MDT on Thursday, and it will feel like it with sunshine and temperatures around 90°. We'll really crank up the heat next weekend with high temperatures making a run for triple digits in the Treasure Valley!
