Forecast: A Summery September Weekend

By Camden Walker

WeatherCamThe D.C. area will see the sun battling the clouds over the next several days. With the exception of Sunday, Friday through Monday will be susceptible to showers and storms, but no day looks like a washout. Temperatures are on their way up for the weekend, and so is the humidity.

Cloudy. P.M. showers, T-Storm? Upper 70s. An increasing breeze from the south will lock in our higher humidity, and this moisture will feed our nearly constant cloud cover. Highs will likely be limited to the upper 70s. Areas to the south, like Stafford or Fredericksburg, could touch 80 if they catch some breaks of sunshine. Much of the day will just see a chance of an isolated shower. But as we get into the late afternoon and evening, the chance of rain goes up to about 50%. Maybe even a thunderstorm.

A chance of a shower here or there (40% chance) will remain overnight. Though the thunderstorm threat should be reduced by mid-evening as the daytime heating wears off. Lows will not dip far -- only into the upper 60s to near 70. They'll be mostly uniform throughout the area thanks to overcast skies and a steady southeast breeze.

Confidence: Medium

When do skies clear out? Keep reading for the forecast through the weekend and beyond. Also, see SkinsCast for Sunday's game at FedEx Field.


Mostly cloudy, shower? Mid 80s. Saturday is looking more promising than it was earlier in the week, as winds shift to the westerly direction and help offer us some peeks of sunshine. Still, it will be quite humid, with highs in the 83-86 range. And a shower or thunderstorm (30% chance) could dampen your spirits and outdoor activities, mainly starting around midday and into the evening.

Only a slight chance (20%) of a shower after dinner as skies go partly cloudy overnight. Low temperatures will hover around 70 degrees by dawn.


Partly sunny. Near 90. Miss the Dog Days of August? They're back, at least for Sunday. Skies will be partly sunny and high humidity will make temperatures near 90 feel even warmer. A pop up shower or thunderstorm can't be completely ruled out, but most should stay dry. If outside -- maybe at the Redskins game? -- be sure to drink lots of water.

Mostly cloudy Sunday night with lows near 70. Not exactly a cool autumnal night.


The weather on Monday depends on the timing of an approaching cold front. If it comes through early, then highs may only make the low 80s with drier air moving in during the day. If it comes through late, then temperatures could rise into the upper 80s as humidity lingers. Either way, it looks partly sunny with a 30% chance of a shower or thunderstorm. Confidence: Low-Medium

If the cold front moves through as planned on Monday, then Tuesday we should finally see mostly sunny skies with highs in the middle 70s and MUCH lower hummidity. Confidence: Medium

Ugh. I was hoping the AC was off for good, but it looks like at least a few more days. . .

The dog days don't give up until October! At least, in my overall evaluation of trend around DC and the Tidewater. We've had mighty hot Indian Summer days too--into October and November. Never a dull transition from one season to the next! ;)

Wide divergence in forecasts. This morning, I was hearing on various outlets that most rain would stay north of immediate area, and that Sunday high would be 96(!).

No ninety-degree days after Oct. 11 according to official records. However, days in the eighties [which can be considered 'hot'] are possible until well into November around here.

Clouds around here, chiefly Sc, Ac and some Ns this morning, with some fine misty rain near Baileys Crossroads. It's now 78 degrees and cloudy with barometer 30.18, falling slowly.

Bombocast tends to agree generally with Southside FFX post on most weekend and Monday weather. Remnants of Ike are progged to pass north of us, probably through PA Dutch country, as the remnant low rides the approaching cold front. Sunday's high could hit at least 94F, with record-busting 96 or higher possible [Sunday's record high is 94F thru 2005 per Bob Ryan's last Almanac.]. It might be our last 90-degree day of this summer season. Monday we could see heavy tropical thundershowers as we get the SE and SW quadrants of Ike's remnants. A tornado watch/warning is possible. Sterling notes that the rain could start early Monday, perhaps before daybreak.

Howard Bernstein is predicting only 90F on Sunday.
