Remember Friday? When it was in the mid-70s? And sunny? And people were barbecuing? Yeah, well, that was all a horrible, horrible tease. As of 2:35 this afternoon, the National Weather Service has announced a winter weather advisory for most of the D.C. metro area, beginning at 9 p.m. this evening, and calling for two to five inches of “wintry mix of rain and sleet changing over to snow.” Remember the last time this region got up to five inches of wintry mix, combined with low temperatures? Because according to one forecast, “the duration and intensity should be long and high enough for accumulations on the roadways to occur so the morning commute will be affected.” Like I said: horrible.
