BILLINGS – Despite the sunshine, today will be the chilliest day the week for most of eastern Montana and northern Wyoming.
A surge of Arctic air will bring cold temperatures in areas east of Billings through the Dakotas through Wednesday. Highs will be mainly in the teens in single digits in this area, with wind chill values reaching as cold as -30.
Tuesday will be fairly quiet from Billings to the west into the mountain foothills, and south into northern Wyoming. Expect sun with just a few clouds, a light wind, and highs mainly in the 20s.
Overnight readings will drop anywhere from the single digits below zero, to the low teens above zero for early Wednesday.
Milder temperatures will start to move into the area Wednesday with dry conditions. But the winds will also increase around the Livingston and Nye areas with Gus to around 50 mph.
A fairly quiet weather pattern will follow, with mild temperatures into the 40s for Thursday, Friday and Saturday. A decent chance of snow showers and colder air arrives Sunday.
