10:05 a.m. — Showers, downpours through mid-afternoon
Radar shows widespread showers sweeping through the region, the remnants of former Hurricane Laura. Some locally heavy downpours are embedded within these showers.
The showers are likely to continue through about mid-afternoon before exiting with skies brightening. At the moment, we do not see a major risk of severe thunderstorms or tornadoes, as the atmosphere will not have the opportunity to destabilize much. We will continue monitoring and will update if there is any significant thunderstorm development.
We should expect about another 0.25 to 0.5 inches of rain or so on top of what has fallen since yesterday afternoon. Most areas have received between 1 to 2 inches (Reagan National 1.72 inches, Dulles 1.44 inches and BWI Marshall 0.9 inches) with some pockets up to 2 to 4 inches east and southeast of the Beltway.

Forecast in detail
We’ve had all kinds of weather in recent days. Perhaps that means a hurricane is the logical next step. Well … it’s not quite a hurricane, but the remnants of the historic storm called Laura are moving by the region today. That means more rain is likely to fall, and some may come with severe weather. Once past those concerns, Sunday is looking mighty pleasant.
Today (Saturday): While the main portion of Laura’s remnants moves to our south, it infuses a front passing the region with additional moisture and spin. Some showers and storms seem a good bet, especially through midday into early afternoon. There should be some clearing late as highs reach the mid-80s. Winds are from the southwest around 5 to 10 mph. Confidence: Medium-High
Tonight: A few showers or storms could linger into the evening. Otherwise, skies are clearing as temperatures fall to the mid- and upper 60s for lows. Confidence: Medium-High
Tomorrow (Sunday): It’s rather nice overall. For now, a little questionable on cloud cover for the actual Nice Day stamp, so we’ll hold for now. Humidity is on the low side and there is a good deal of sun. Highs are mainly in the low 80s. Confidence: Medium-High
Tomorrow night: There should be a fair amount of stars early in the night, with increasing clouds likely over time. I’d guess we stay dry, but it’s not impossible a few showers are around by dawn. Lows range from near 60 to the mid-60s. Confidence: High
A look ahead
Clouds and rain odds increase Monday, especially deeper into the second half. There is some chance heavy rain moves through, heading into the night — far from certain at this point though. Highs shoot for the upper 70s and lower 80s. Confidence: Medium
Coming off rain-cooled lows in the 60s, gray skies and some drips may persist into Tuesday. I’d think most of the rain is done by daylight, but clouds could be quite slow to depart. Temperatures rise to around 80. Confidence: Medium
