Message 1’s have been extended for central and eastern portions of the District until 2:00 AM Friday, May 31, 2024
Strong storms continue to impact central and eastern portions of the District and will slowly meander eastward over the next couple of hours. By 2am storms will likely weaken as they move out of the District and should no longer pose a heavy rainfall threat. Storms over the next couple of hours could pulse up resulting in some isolated heavy rainfall with some storms still severe across portions of the District. The largest threat will still be a quick 0.50” in 10-15 minutes with longer lasting heavy rain possible if storms decrease in speed. Currently storms are moving E/SE at 10-15mph. Temperatures will decrease overnight with lows dipping into the 40s.
STORM RAINFALL POTENTIAL AND DURATION: Typical thunderstorms will produce rainfall of 0.10-0.30” total in 10-30 minutes.
Moderate to strong storms have the potential to produce heavy rainfall of 0.30" to 0.60” total in 10-30 minutes.

WORST CASE SCENARIO: Strong stationary, or training of thunderstorms has the potential to
produce 1.20" total in under 30 minutes.
