A. Camden WalkerWe might just get to dry out a bit, and sweat a little less, as we get into this weekend. I won't proclaim an end to summer, by any means, but compared to big storms and oppressive heat, the next few days will seem like winners with highs in the 80s and less of a shower/storm threat. Here's to hoping umbrella use and power outages are on the decline.

Today (Friday): We're not expecting anything like yesterday's multiple rounds of severe storms. But some showers are possible (50% chance; only a slight chance of thunder), especially during the morning through midday. Humidity won't be as tropical as yesterday either, but still moderate to high before trying to decrease some during the afternoon. Temperatures? They continue to move in the right direction, as partly to mostly cloudy skies and breezes from the east (10-15 mph at times) hold highs to the mid-80s. Confidence: Medium-high

Tonight: Not a bad evening to be out with dwindling rain chances and temperatures falling into the 70s. Lows drop to around the mid-60s outside the Beltway, and around 70 downtown. Mugginess is moderate with partly cloudy skies and light winds. Got tickets to tonight's Redskins game? Check out the season debut of SkinsCast. Confidence: Medium-High

Tomorrow (Saturday): A little cooler and with continued lower levels of humidity (in the moderate range). Highs should top off in the upper 80s. Winds stay light as at least partly sunny skies make for what should be a pretty nice day. Enjoy it while you can -- before humidity and temperatures surge upward again. Regarding rain, I'm fairly confident we'll eke out a dry day, with the chance of a shower or thundershower around 10% or less. Confidence: Medium-High

Tomorrow Night: The evening should feel nice -- still not terribly muggy -- with temperatures dropping into the 70s. Overnight, lows reach the mid-to-upper 60s (suburbs) to the upper 60s to low 70s (downtown). Confidence: Medium

Sunday: Continued pleasant highs in the mid-to-upper 80s are likely. But you'll notice a stickier feeling to the air with humidity back up -- blame a light a breeze from the south. The increased moisture in the air leads to the return of shower/storm chances, but for now only around 20-30%, which continue in that range Sunday night as lows fall back to the upper 60s to near 70. Confidence: Medium


Monday and Tuesday feature a humid and partly cloudy start to the week, along with highs in the upper 80s to near 90. A cool front slowly approaching from the west means a 40-50% chance of showers and storms. Confidence: Low-medium

When I went to bed a a little before 1 a.m., the line of showers that had formed in eastern Maryland was about 15 miles away and moving toward me in Oxon Hill/Fort Washington. We were under a flash flood warning. But as far as I can tell this morning, it never arrived. I didn't hear any heavy rain overnight.

What happened?

Looks like it did migrate west, but weakened with only some pockets of heavier showers. Guess the atmosphere finally ran out of gas.

Ah, nice cool low 70's out there. Paradise.

Such an odd drifty rain pattern today that some might actually hit NW Spotsy.

Precipitation has been difficult to predict with any confidence yesterday & today. Almost anyone can see a pop-up shower in this type of atmosphere!

Wanted to run by this rain discrepancy at my 2 locations. For the two rain events yesterday, my home in s. arlington got 1.25". However, when I checked the rain gauge at my work in NE DC (capitol hill) this am it was at a whopping 3.20"! I know we got some showers this am. My arlington #s don't include the showers this morning.
