| Message 1’s will continue to be valid as the threat for heavy rainfall remains. A potent round of storms has moved eastward this morning and out of the District. A few scattered clouds has helped keep temperatures cool this morning. This may help the severity of storms as we head into the afternoon, however, with good upper-level support in place, with elevated surface dew points in the mid to upper 50’s, a good chance for strong to severe storms will be possible this afternoon and evening. Strong to severe storms could produce large hail, up to 1.5”, frequent cloud to ground lightning and heavy rainfall leading to localized flooding. The next round of storms will be between noon and 2pm for western portions of the District with storms moving east between 15-25mph. These storm movements should help limit point rainfall amounts, with the biggest threat being an anchored storm formed along an outflow boundary, or training of thunderstorm cells. Multiple rounds of storms will be possible this afternoon and evening with a slight chance for lingering showers past midnight tonight. |
WORST CASE SCENARIO: An anchored strong thunderstorm or training of thunderstorm cells has the potential to produce up to 2.00” in under 60 minutes.
