Large hail and damaging winds elude D.C., smack surroundings

Severe thunderstorms with golf ball size hail and 60 mph winds erupted around the region Thursday afternoon and evening, but those inside the Beltway would have never known (if they weren’t paying attention).

Here’s yesterday’s doppler-indicated rainfall totals from the region: you can’t miss the gap over the District:

(We’ve documented this D.C. split phenomenon repeatedly over time but I remain convinced it occurs completely by chance and that there’s no compelling physically-based reason for it. The District’s rainfall totals – over time – are not less than its surroundings.)

But to the north, south and east of the District, scores of reports of severe weather were logged by the National Weather Service Storm Prediction Center – for both damaging wind and large hail.

In southern Maryland – numerous trees came down – including several on homes in Calvert County according to local storm reports.  Multiple reports of large hail came in from Howard County, up to the size of golf balls (1.75 inches in diameter).

Here is a summary of the storm damage reports compiled by the National Weather Service forecast office in Sterling, Va. serving D.C. and Baltimore, from 9:55 p.m. last night:
