Discussion

The passage of a “back door” cold front will bring cooler conditions to the region for both today and tomorrow as low-level winds have shifted from a southwesterly direction to north-northeast. (I refer to this kind of cold front as a “back door” since it “sneaks in” from our northeast instead of the more conventional approach of a cold front from our west). Temperatures will begin to rebound on Friday and it’ll be quite mild this weekend. The weekend becomes quite wet, however, with occasional rainfall likely from later Saturday through Sunday. Some of the rain can be heavy at times late this weekend and a strong thunderstorm is possible. It turns cooler on Monday following the passage of a more conventional “west-to-east-moving” cold frontal system.
