First Alert Evening Forecast for Dec. 18
Another cold day in Idaho. Count on one more night of extra chilly temperatures before we warm up (relatively speaking).
Tonight, partly cloudy and cold. Overnight lows ranging from the low single digits to the -10’s. Patchy fog will also be an issue in the early morning hours.
Monday, partly cloudy with increasing clouds in the afternoon as a storm moves in from the NW. Snow showers will start in the central mountains around noon, and then spread along the continental divide in the afternoon. The northern plain could see a few snow flurries, but they won’t see much. Daytime temperatures will be relatively warmer with highs in the teens and low 20’s.
Tuesday, mostly cloudy skies with on-and-off rain and snow showers. Most areas will see just snow, but Pocatello and lower along the Snake River will see afternoon rain. Highs much warmer, topping out in the upper 20’s and 30’s.
Wednesday, partly cloudy to mostly clear with just a few AM snow showers in western Wyoming. Highs will be mainly in the 20’s and low 30’s. Note: As Wednesday is the Winter Solstice, winter officially starts today. That also means the days will slowly grow longer from here!
