Polar Vortex 2019..At least it's dry cold

Life-Threatening Wind Chills Tuesday afternoon through Thursday morning

Cold air the likes we haven't seen in over 20 years will affect the region this week. Temperatures will fall below zero tonight and will likely not rise back above zero until Friday morning. This is especially true for locations inland away from the moderating effects of Lake Michigan. Tuesday night through Thursday morning will be the coldest period. Low temperatures are forecast to be -20 to -35 both Tuesday and Wednesday nights. Temperatures will struggle to recover to the teens below zero on Wednesday for highs. Combine these bitterly cold temperatures with a westerly breeze of 10 to 15 mph with gust of 20 to 30 mph will produce wind chill values of -40 to -55. This is a life threatening situation. Temperatures will moderate next weekend.
