There's a nasty cold air damming event going on across the Piedmont this afternoon. Here in Podunk, North Carolina, our high temperature was supposed to be 68°F. The current temperature is 48°F. The wedge is cruel and stubborn.
The temperature in Great Falls, Montana dropped more than fifty degrees in six hours on Friday, going from 54°F at 2:53 PM down to 2°F at 8:53 PM. Now that's a cold front.
A strong cold air damming event took place early this week, leading to dangerous ice accumulations from freezing rain and sleet in areas from Pennsylvania to North Carolina. Cold air damming is one of the most interesting weather events in the United States, and can be one of the hardest to accurately predict.
