A WIND CHILL ADVISORY is in effect for eastern Montana through Thursday morning for wind chill values as low as -40.
Arctic air has spilled into the eastern part of Montana. It's just a glancing blow, and the arctic air won't remain in Montana for long. However tonight into Thursday morning will have dangerously cold wind chill values in northeast Montana. Plus, roads will remain slippery in spots after this latest round of snow. Thursday may start out cold but there will be a decent amount of sunshine and warmer temperatures by the afternoon. Southwest wind will increase through the day as a chinook develops pushing temperatures into the upper 30s and low 40s off of the Rocky Mountain Front and across north-central Montana. Even chilly northeast Montana will warm into the 10s and low 20s by late in the day as the arctic air departs. Friday is Valentine's Day and there will be snow showers, wind, some sun and seasonable temperatures. Presidents' Day Weekend will start out with scattered snow showers on Saturday with windy conditions. Highs will be seasonable in the 30s to around 40. Sunday will have a good chance of widespread snow in central and western Montana. Snow will also fly in neighboring states so keep that in mind if you plan on travelling. Monday will be partly cloudy with scattered snow showers and a light accumulation is possible. The weather through the weekend will be unsettled but not unexpected for this time of year.
Have a great day.
