| - | Message 1's will continue valid for the District through 9:00 PM. |
| - | The majority of the strong thunderstorm activity remained over far eastern areas of the District this afternoon. These storms have moved E and NE with generally quiet conditions over the District currently. An outflow boundary from previous storms continues to move through the District from W to E and will move into the foothills over the next hour. Additional thunderstorms may develop as this outflow interacts with the higher terrain. |
| - | If additional thunderstorms are able to develop they will be capable of producing brief heavy rainfall although the chances are much lower than earlier today. By sunset the risk for heavy rainfall is expected to be low enough to allow messages to expire. |
WORST CASE SCENARIO: A strong stationary thunderstorm will have the potential to produce up to 1.4" in 30-60 minutes.
