It is going to be brutally cold tonight as lows are going to be in the -20s and -30s, and wind chills are going to be in the -40s and -50s. Definitely stay inside if possible. We are also going to have decreasing clouds tonight, and if the skies clear quicker than expected, then the actual low temperatures may be colder than what is currently forecasted. It is also going to be breezy tonight in portions of north-central Montana as sustained wind speeds are going to be between 10 and 20 mph.
For tomorrow, it is going to be extremely cold once again as highs are only going to be in the -10s, and for a lot of the day, wind chills are going to be in the -30s and -40s. It is also going to continue to be breezy tomorrow in northeastern Montana and eastern portions of north-central Montana as sustained wind speeds are going to be between 10 and 20 mph. The one good thing about tomorrow though is that we are going to have mainly sunny skies, so even though it is going to be really cold, at least it is going to look nice outside!
After another bitter cold night Thursday night (lows in the -20s and -30s), the temperatures will start to warm up on Friday with highs in the 0s and 10s in portions of central and north-central Montana.
