Temps take off

A strong cold front has sunk into the center of the country, plunging parts of the upper Midwest to single digits, both above and below 0. Ahead of that front, southerly flow was also quite robust. In Virginia, it was aided by a brisk westerly flow over the Appalachians that led to an even more efficient warming pattern, thanks to some downslope flow and no small degree of cold air damming. Richmond, as a result, was able to see temperatures climb all the way to 70 degrees yesterday. Nobody was expecting that, but if you’re going to err on a temperature,┬áisn’t this the way to go? A rare late November 70 is a treasure, forecast correctly or not. Accuweather ended up with the top spot.
