Latest Rainfall Forecast & Timing of the Severe Storms

Latest North American Model Future-Cast Radar

Thunderstorms are possible overnight between 12am and 4am with a lull likely thereafter.

The worst of the weather arrives between 2PM Wednesday and 2AM Thursday when strong to severe thunderstorms are expected with torrential rain causing flash flooding. The risk of tornadoes is elevated tomorrow afternoon and evening as a warm front lifts through the area and wind shear from Ida’s remnants pass overhead.

The afternoon rush hour tomorrow is looking like a complete shit show, I wouldn’t be surprised to see school systems offer early releases.

The worst combination for DC Area drivers is to become trapped in flash flooding on clogged roadways with potential tornadoes. That could be a reality tomorrow if the Federal Government doesn’t offer a staggered early release. Plan accordingly!

Regional Rainfall Totals

Forecast models have been very consistent with 2-4” in The DC Metro, 1-3” south and east and 3-6” + north and west of the Capital Beltway.

River flooding is likely to continue through Saturday as it will take some time for the trillions of gallons of water to make its way down all of the streams creeks and tributaries that feed into the Rappahannock, Potomac, Shenandoah, and Susquehanna Rivers.
