A compact system is promising a fairly cloudy and cooler than normal weekend, as well as a few forecasting headaches. The size of the disturbance means its footprint is smaller than many, and as is often the case, the D.C. area might be livin’ on the edge. The short story is: odds of more significant rain probably go up the further east you are, but that’s not necessarily a given and everyone should get a little wet. Other than that, don’t plan on seeing a lot of sun till at least Monday.
Today (Saturday): The rule of the day is plenty of clouds and a cooling east wind. Rain will be in the outlook as well, but it’s still somewhat uncertain where the most consistent (and heaviest) activity will be. What we can expect is showers overspreading from south and east as the day goes. Periods of showers could begin as early as mid-morning, but the second half of the day is favored. A t’shower is also possible late. If that’s not enough, there might be a more general drizzle thanks to the moist atmosphere in place. Highs are muted -- they struggle to get much through the 70s if rain is in place early, nearer 80 if not. Confidence: Medium
Tonight: Everyone should see periods of showers overnight with perhaps that more widespread drizzle and areas of fog. Lows range from the mid-60s to near 70. Light east winds continue. Confidence: Medium

Tomorrow (Sunday): The disturbance is really in no hurry to leave, partly because it’s pressed in between the same two highs that will guide Isaac into the U.S. by next week. Showers remain possible through much of the day, though they might tend to favor the first half. If we’re lucky a few breaks show up in the afternoon. Highs could be similar to today, though they want to head toward 80 or low 80s with less in the way of afternoon rain.
By the time we’re done with the rain, a general swath upwards of .5” or so is possible -- maybe even toward 1”+ in spots. But, it’s a small system and small movements can bring totals down. As noted, east and south might end up favored. Confidence: Medium
Tomorrow night: Mostly cloudy conditions could persist into the night, as may some showers. It’s also possible they’ll clear out of here prior. We’ll probably have to wait till tomorrow to get a better idea on timing by this range, but rain chances should at least abate after midnight it would seem. Lows again range from the mid-60s to near 70. Confidence: Low-MediumA LOOK AHEAD
On Monday, we return to some late-summer conditions with partly sunny skies and temperatures reaching the mid-to-upper 80s. It’s hard to totally rule out a late day shower or storm so we’ll go with a 20% chance of such, however the main focus of the cold front is still pretty far west so I would not expect anything widespread. Confidence: Medium
Tuesday appears to bring the frontal passage, and with an elevated (30-40%) risk of scattered showers or storms. There’s some extra uncertainty here due to Isaac and its potential influence on the pattern, but for now it looks like the front will keep us from feeling its main effects. If things play out as planned, highs make the mid-80s to near 90s prior to any rain. Confidence: Medium
