Showers Possible, More Likely Tomorrow


Scattered thunderstorms were breaking out late this afternoon south of the Beltway along I-95 and more widespread southwest of Culpeper toward Charlottesville. These were mostly moving eastward. Temperatures which had stayed mainly in the upper 80s popped up to 92° at National Airport with the switch to a more favorable west wind at 3pm.

Tonight and Tomorrow

There is a 50% chance of scattered showers and thunderstorms through this evening. The most likely targets are the areas south and west of the District. Lows tonight under hazy skies will be from the upper 70s downtown to the low 70s in the 'burbs. Tomorrow will again be muggy but with less sun than today in most places and highs in the mid 80s. The chance of mainly afternoon thundershowers, some possibly severe, is 60%.

For the outlook through the rest of the weekend, see Camden's post below.

Tropical Topics

After making landfall early this morning at Nantucket, Beryl lost its tropical characteristics as it headed northeastward to Nova Scotia. The last tropical advisory on the storm was issued at 11am. (Just for the record, the official pronunciation is either "Burl" or "Ber-il".)
