Today: Mostly sunny and very warm. 86-90. | Tonight: Mostly clear. 67-72. | Tomorrow: Lots of sun, very warm. 87-91. A Look Ahead


Unlike last weekend, there's no heat wave coming, but it will be plenty warm. The mercury will rise well into the 80s to perhaps 90 both weekend days. Humidity will be noticeable but not obscene. An emerging weather story is the lack of rain. After the 5th driest July on record, August rainfall is just half of average and no rain is likely through early next week.

Today (Saturday): Pretty typical Washington August weather to kickoff the weekend. High pressure will give us plenty of sunshine, helping temperatures into the upper 80s. It will be somewhat humid, but a little less sticky than the preceding 5-7 days. Don't expect much of a breeze at all. Confidence: High

Tonight: Just a few clouds overnight. With light winds, the suburbs will drop into the mid-to-upper 60s overnight. Downtown locations will bottom out around 70. Confidence: High

Tomorrow (Sunday): Tomorrow will be pretty similar to today. Maybe it's a degree or two more of us may hit 90. Humidity will remain moderate to high with light winds from the east at around 5 mph. Confidence: High

Tomorrow Night: Partly cloudy and mild overnight. Lows will range from the mid-to-upper 60s in the cooler suburbs to near 70 downtown. Confidence: Medium-High


Monday and Tuesday won't be much different than the weekend, though perhaps a few degrees warmer. Both days should feature partly to mostly sunny skies with highs into the low 90s. Overnight Monday, it will be warm and muggy with lows from the upper 60s to the low 70s. No rain is likely although a thunderstorm can't totally be ruled out by late Tuesday. Confidence: Medium-High

Our dry spell seems to occur this time every year. However, we get a tropical system in September and/or October which dumps two months worth of rain in one day.

Nature always seems to balance things in the end.

Actually, I should say it's the first NAMED storm of the season.

Ah, no wind! Heh, heh...the new bf is in a prescribed Sailing 101 class today. At least there seems little chance of a tstm.

Nice weather...a bit too warm and dry enough that the "much-needed-rain" crowd is beginning to whine. How easily they forget the deluge we went through this reason we have no drought issues.

My latest check on the tropics had two depressions, but no named storms yet...will be interesting to see wher they go. There's a frontal boundary on the Atlantic coast and should be a trough here next weekend.

An area just off the Florida coast near Key West has become increasingly organized today, now looking pretty good. National
Hurricane Center just started following it with 30% chance of development -- may be understated if trends continue. See Key West radar.

We have now have Bill Ana and now a new Invest 91L in the GOM. People down there should keep a close eye on that. If convection can sustain itself through the night, COULD see rapid intensifying. Ana is looking pathetic yet again. To much dry air, wind shear. Strengthing with Invest 91L is at a low potential for developing because pressures are very high in the Gulf but eyes should be kept on it.
