Forecast: Drying Out After Deluge

By Brian Jackson

By Brian Jackson

Heavy Rain Forces Evacuations, Causes Floods Across Area

Mother Nature gives us a couple of days to dry out from the tropical rains that drenched the area yesterday. High pressure in Hanna's wake builds in and gives us clear and warm conditions today and tomorrow. We'll have another chance for rain on Tuesday before we dry out again under cooler conditions later in the week.


Sunny skies, 87-90. We earned ourselves a nice day with the deluge that accompanied Hanna yesterday, and we will be rewarded. High pressure will build in behind the departing storm and give us mostly sunny skies. We'll warm into the upper 80s with winds out of the northwest at 8-13 mph.

For the overnight, skies will remain clear. North winds will drop the humidity and allow most of us to cool into the lower 60s. For you city-dwellers, expect a few degrees warmer.

Keep reading for the forecast through the middle of next week.


Mostly sunny and very warm, 88-91. We'll enjoy another day to dry us out even more on Monday. Skies will continue to be mostly sunny and temperatures will reach right around 90 degrees. Winds will shift to out of a more southerly direction and bring in some humidity by the afternoon.

We may see increasing clouds by Tuesday morning, but overnight Monday should be mainly clear. We'll be a bit warmer with lows only reaching the upper 60s due to southerly winds ahead of an approaching cold front.


Tuesday brings with it our next chance for rainfall. A cold front will move in during the afternoon setting off some showers and thunderstorms as it moves through. A chance for storms will remain for us into the evening hours. Highs should reach into the mid 80s under mostly cloudy skies. Confidence: Medium-High

Wednesday sees a cool down for us behind the cold front. Skies should clear out by the afternoon but temperatures will struggle to reach 80 degrees, topping out in the upper 70s. Confidence: Medium-High

Thursday will continue to be very pleasant with clear skies and temperatures once again in the upper 70s. Confidence: Medium-High

Late yesterday afternoon I was at Bellehaven picnic area, as well as on the G. W. Parkway bridge over Hunting Creek. The creek was swollen with water, which was brown and rapidly rushing toward the Potomac. It was something to see. While I don't know for sure, it seemed like the creek's velocity could have been as high as 25 mph.

The air today definitely has that crystal clear post-storm feel to it. I don't care how you feel about severe weather. There's nothing that compares to the weather the day after a storm.

Hanna is gone, with more rainfall on our "weak" side of the storm than could have been predicted.

The focus shifts to the DanceCast, with stormy weather being predicted for both the swing dance Tuesday night and next weekend's active dance schedule. It's September now; hence severe weather activity should be diminishing [outside of the tropical systems]. Nonetheless we seem to have a pretty nasty lightning forecast for Tuesday PM. It happens that GottaSwing has a group out of London at the Clarendon Ballroom Tuesday night and they are charging $5 extra for the dance, so lightning is not welcome from their business standpoint as evening severe weather could cut down on attendance. The Weather Channel is also threatening us with rain next weekend; there are dances scheduled all three nights. We have all the rain we need and then some thanks to Hanna. I just heard that the DCA total is now 5+ inches, not the 3.50 I heard last night.

I have recorded 40.1" now since Jan. 1, which I believe is more than we average annually.

El Bombo, this isn't a personal attack, but what does having a dance or attending one have to do with the forecast? You make your comments sound like something you'd write on your personal blog. Most people mention "evening activities" and don't go into further detail. I'm curious as to why weather impacts these dances so heavily, are they held in a building or is it outside?
