| - | Message 1's will continue valid through 10:00 PM although the threat for heavy rainfall is diminishing. |
| - | Strong and severe thunderstorms impacted eastern and southern areas of the District this afternoon and early evening with generally quiet conditions over the District at this time. An outflow boundary from the earlier storms is pushing back to the NW and may initiate new thunderstorms over NW portions of the District that had minimal coverage so far today. |
| - | If thunderstorms are able to develop over NW portions of the District later this evening ample surface moisture still in place will allow for storms to produce heavy rainfall. The most likely outcome is that minimal if any new development will occur but a low threat remains. |
WORST CASE SCENARIO: A slow moving strong thunderstorm or training of thunderstorm cells may result in up to 2.5" of rain in 60-90 minutes.
