| Message 1’s will be extended until 11:00pm as the threat of heavy rainfall continues. Another round of showers/isolated thunderstorms will move through the District from the NW to SE over the next couple of hours bringing some additional rainfall across most of the District. These storms are moving between 10-20mph which is limiting point rainfall amounts. However, with dew points in the upper 50’s to low 60’s, a stalled shower, or moderate to strong thunderstorm will have the potential to produce a quick 0.4-0.6” in 10-30 minutes. Typical showers/isolated thunderstorms will produce between 0.05-0.25” total rainfall, with a few pockets that could produce isolated higher amounts. A chance for off and on showers will persist through the overnight with any shower activity coming to an end between 2-3am. Skies will gradually clear through the rest of the overnight as lows decrease into the low to mid 60s. Very little overall chance for tomorrow with another chance for storms by midday, with similar NW to SE storm motions. |
WORST CASE SCENARIO: A strong thunderstorm, or training of thunderstorm cells has the potential to produce 0.60-1.20” in under 60 minutes.
