After a 10 day streak of temperatures at or above 70° in Boise, a cooler temperatures arrived for Monday. Expect seasonable weather on Tuesday before big changes arrive Tuesday night.
A cold front in advance of a strong storm system will bring significant moisture into the area Tuesday night lasting into the first part of Wednesday. Temperatures will drop to the lower 60s on Tuesday which is normal then down into the lower 50s on Wednesday behind the cold front.
In central Idaho the higher elevations will see the first significant snow of the season Tuesday night and Wednesday with 1"-3" possible at 5000 feet including the cities of McCall, Donnelly, and Cascade. Around a foot of snow is possible on the summits of Brundage Mountain Resort and Tamarack Resort.
For the Treasure Valley I expect some moderate rain Tuesday night through midday Wednesday. This will be followed by the first widespread frost & freeze of the season Thursday through Monday. There is even a chance of snow mixing in with rain showers Friday night into Saturday morning.
It will feel like late November as we move through the last days of October. Highs will struggle to get out of the 40s in the valley with overnight lows dipping into the 20s. In the mountains, high temperatures will be in the 30s with frigid overnight temperatures falling into the single digits and teens from Wednesday into the weekend.
A gusty breeze develops on Saturday leading to wind chills in the 20s and 30s throughout the day.
