Forecast: Rain Looms at Week's End

By Matt Rogers

Tip top weather through tomorrow

Our stellar series of excellent D.C. days should carry on for at least two more today and tomorrow. Comfortable highs in the 70s and lots of sunshine will prevail through midweek. But I'm hearing more from District dwellers and suburbanites alike about increasing allergy problems due to dry weather. Sure enough, the rain gauge at National Airport has not seen measurable precipitation for 11 days now. This should change Thursday and perhaps in a big way with rain persisting into early Saturday.


Nice, Nice, Nice. Low to mid 70s. Look for scattered clouds, breezes from the northeast, and extra-comfortable temperatures topping out in the lower to middle 70s today.

Tonight, partly cloudy with lows in the 50s suburbs to lower 60s for the interior. Very cool and comfortable breezes yet again.

Confidence: High

Keep reading for the forecast through the weekend, and see NatCast

Last Day of the Nice Stuff. Low to mid 70s. Comfortable northeast breezes will bring in some clouds at times, but again we are looking at a great early autumn day with highs in the lower to middle 70s.

Wednesday night offers up partly cloudy skies, comfortable breezes, and lows in the 50s to lower 60s once more.

Confidence: Medium-High


Thursday is expected to see a cloud canopy envelop the area. The loss of dominant sunshine will only allow temperatures to peak in the upper 60s to lower 70s, and we could see the rains arrive as early as mid to late afternoon (30%). Thursday night should feature our needed rains (60% likelihood) with lows dropping to around 60 (just below in the suburbs, just above in the city). Confidence: Low-Medium

Friday should feature more clouds, periods of rain, or just showers at times. Probability of rain is about 60% and this should increase as the weather models get more confident on this story. We should see highs in the upper 60s to around 70. More showers are slated for Friday night with clouds and lows again near 60. Confidence: Low-Medium

The last weekend of September (can you believe it?) could start with some lingering clouds and showers from the late-week weather system, but the current indications continue to favor clearing skies during the day on Saturday and then a decent weather revival for Sunday. Highs should be in the middle to upper 70s and lows in the upper 50s to lower 60s. Confidence: Low-Medium

Sounds like I'd better try to dig up some crew today....oh, DARN, how I'll hate to leave the office early but I guess it can't be helped.

~sg, you are clearly suffering. An afternoon outdoors sounds like just what you need.

while it's a quiet weather day, I'd like to ask CWG if they have any plans for a mobile app for their site (or is there one already)

@Murre: Why, thank you! By the way, check this out: Apparently they have it at Whole Foods in Rockville. We must be prepared for the next storm!

The models for what-might-become-Kyle-or-not(both computer and ensemble) that I found in Weather Underground show this whatever-it-is tracking well away from us. Then again, what do I know about weather models? This WOULD be the one weekend that we've decided to spend in Busch Gardens and Williamsburg. RATS.

A coastal "monster" such as this is definitely NOT 'much-needed'!

If we get three days or more of such windy crud, it will be worse than Hanna, and much more will be RUINED than just my Friday night dance at the Elks Lodge.

It would be better to get a few hours of gentle rain with a light breeze at best than a 3-5 day DELUGE with gale-force winds. As things now stand we have over 4 inches of rain for the month courtesy of Hanna. Windy rain is NO GOOD; it wrecks umbrellas [which can cost $10.00 or more each at today's prices!].

@~sg: Thanks! I'll look for it at my Whole Foods.

jeffc -- we don't have any immediate plans for a mobile app. but it's something we are very much interested in providing at some point in the future.
