Severe Storms expected in the DC area this afternoon

Storm Threat this afternoon after 2pm

Strong to severe storms are possible this afternoon mainly after 2pm. The main threats will be damaging winds in excess of 60mph and heavy rainfall. A Flash Flood Watch has been issued for the DC Metro until later this evening, rainfall totals of 1 to 2 inches are expected with the possibility of 3 to 4 inches.

A Severe Thunderstorm Watch already extends from the PA border north through NY, CT, MA and VT until 8pm. We are expecting the Watch to be expanded southward by early afternoon.

TIMING:

Storms will enter the western parts of the area around noon. The strongest activity close to DC is approaching the I-81 corridor as of 11:30 this morning.

We’re anticipating a line to develop and move through the DC Metro between 2pm and 5pm. This will be the highest likelihood for severe weather in the form of damaging winds and heavy rain.

Areas east of DC will experience the severe threat through at least 6 or 7pm, with the heavy rain threat persisting through the evening hours as the cold front moves through the region.

LOOKING AHEAD:

Humidity levels will drastically fall off tomorrow and Wednesday with dewpoints in the low 60s rather than low 70s. Humidity should take a break until at least Thursday but appears like it will return by the weekend.
