| Message 1’s have been extended until 6am as the threat of heavy rainfall remains across the District. Message 2’s will continue valid until 6am as well. Persistent storm development continues at this time. These storms will likely continue over the next several hours with isolated rain showers possible through daybreak. Storms have weakened quite a bit from the afternoon and evening severe storms. However, elevated surface moisture with dew points still in the 50’s, combined with continued upper-level support, storms will continue to impact several areas over the District. These storms still contain moderate to heavy rainfall, with some stronger storms just off the perimeter of the District, which can create additional gust fronts through the overnight resulting in a chance for additional strong storm development within the District. Heavy rainfall from thunderstorms will easily produce excessive runoff roadways and may result in flash flooding within the District. Due to snow melt and recent rains many creeks and streams are already running relatively high and additional rainfall will exacerbate flows as the day progresses. |
WORST CASE SCENARIO: A nearly stationary strong thunderstorm may result in up to 2.4" of rain
in 45-60 minutes.
