Now Cloudy, damp, cool.
While temperatures in the Washington metro area moderated somewhat from yesterday's damp chill, within about 100 miles, spring-like conditions prevailed from central Virginia southward. Daily temperature records were set at Lynchburg, Roanoke, Blacksburg, Richmond, Norfolk, and Wallops Island.
Temperatures in the low and mid 50s were accompanied by dewpoints in the mid and upper 40s, but despite the humidity, mist and haze were much more prevalent than rain showers, which were mainly light. Highs were: National 54°, Dulles 48°, BWI 47°.
Clouds and humidity will persist into tomorrow with at least a chance of some showers. The models frequently underestimate the tendency of this type of cold air wedge to hang on in the area, but some warmer air is likely to make it this far northward in the next couple of days before everything gets swept eastward toward the end of the week.Real-time Mesoscale Analysis (RTMA) from NWS/NCEP at noon today shows a 40° temperature range in about 100 miles from near DC to central Virginia.
Tonight and Tomorrow Mostly cloudy, chance of showers, possibly milder.
There's a 30% chance of light showers tonight with lows 41-45°. Some patchy fog is possible in the early morning hours. Tomorrow will be mostly cloudy with a 30% chance of showers, but some sun is possible, especially in the afternoon. Highs will be anywhere from 52-61°, depending on how much of the warm air can move northward.
