| Storms have initiated over the District this afternoon and will continue into the evening hours. A few moderate to heavy showers have already impacted areas north with additional storms likely for most areas within the District as storms have increased in coverage towards the west. Storm motions are 15-25 mph from west-northwest to east-southeast, which should limit point rainfall amounts, but storms have been anchoring over specific areas which could result in higher isolated rainfall amounts. The biggest threat will be this afternoon and early evening will be a quick 0.40-0.80” in 10-30 minutes. Storms will continue to impact the region over the next several hours with lingering showers possible into the late evening. Storms also contain some hail and frequent cloud-to-ground lightning. Once the initial round of storms moves through the District, storms will dissipate in strength into the later evening with a few scattered showers possible. Skies will gradually clear overnight with temperatures dropping into the low to mid 50s. |
WORST CASE SCENARIO: Stationary thunderstorms, or training of thunderstorm cells have the potential to produce up to 1.50” total in 30-60 minutes.
