NowCloudy, cool. Warm air moving over the top of the cold high pressure area which has dominated our weather for the last several days has produced considerable high cloudiness from NoVa across the Washington metro area into SoPa. This has kept temperatures in the low and mid 50s this afternoon (high of 54° at both airports), while in much of RoVa (rest of Virginia) more seasonable 60s prevail.
Meanwhile, as the high retreats eastward, a low pressure area developing over the Southeast has the potential to tap into some tropical moisture, bringing substantial rain to portions of the East Coast toward the middle of this week. (One model, most likely overdone, this afternoon develops as much as 9" of rain along and offshore of the Carolina coast in the 48 hours ending Thursday morning.)

Tonight and TomorrowCool, rain developing late. Skies will be mostly cloudy tonight with lows in the mid 40s in the city to near 40° in the cooler 'burbs. Rain will develop from the southwest across the region Election Day afternoon, with a 60% chance of rain by evening in the immediate metro area. Highs will be in the upper 50s.
