Maybe May or Maybe Not
Steve Scolnik @ 5:49 PM
Currently
The May sun through partly cloudy skies has driven temperatures to summer-like levels in the Washington metro area ahead of a strong cold front approaching from the Great Lakes. Behind that cold front, temperatures were in the teens this morning across western Ontario and through Manitoba and Saskatchewan. There is a Winter Weather Advisory in effect through tonight for the Black Hills of South Dakota; snowfall amounts of 2-5 inches are expected.
At 4pm, several area locations, including Leesburg, Stafford, and Winchester, were at 90 degrees, while the official DC anomalous airport reading was only 80. By 5pm, a more southwesterly wind direction had brought the airport reading to 84. Humidities are also higher than yesterday; dewpoints range from the upper 50's to the low 60's. The nearest precipitation on radar was in northern West Virginia and far western Maryland.
Outlook
Balmy conditions will continue tonight, with a slight chance of a shower and lows in the lower 60's. Tomorrow will be considerably cooler with overcast skies, northerly winds, and a 30% chance of showers; high temperatures will depend on the timing of the cold front passage and the amount of clouds; current model guidance indicates a high of 72. Even cooler temperatures are on tap for Friday, probably no higher than the mid 60's.
