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.

Monsoon season is in full swing across parts of the western United States as areas from Nevada to Oklahoma — including most of the state of Colorado — are under a flash flood watch for the next couple of days. Parts of the region could see three to four inches of rain by the time the event is over on Wednesday.
