Did we over-sell the cold air? Yeah, I don’t think so, either. The coldest air mass in two years perhaps featuring the coldest temperatures in the last 4 years has settled across the region. Gusty winds have added significantly to the chill. Under clear skies, air temperatures will drop between 7 and 16 degrees tonight and occasional breezes will knock the wind chill to zero or lower at times. Another sunny, breezy and bitterly cold day lies ahead tomorrow. Tomorrow evening, a fast moving upper-level disturbance could produce a few flurries or snow showers.

It will be back to sunshine Thursday with highs struggling to reach the 30 degree mark. And then there is Friday…an area of low pressure will approach from the west just as the arctic air mass starts to retreat to the north. Right now, we are calling for a 60% chance of snow which could be mixed with sleet and freezing rain at times. Precipitation type is not certain because borderline temperatures will be observed above the surface where the precipitation will be produced. It does not appear to be set-up for major accumulations but given how cold the ground and roadways will be at that time, it could have a significant impact on travel.
