| A stratus deck has developed behind a cold front sweeping across the District this morning. Cooler temperatures and morning cloud cover will limit thunderstorm development this morning and during the early afternoon hours. However, upper-level conditions are favorable, and atmospheric moisture across the region remains elevated in the wake of last night's significant hailstorm. Afternoon highs will reach the mid 70s, dew points in the mid 40s, and precipitable water (PWAT) values around 0.7”. There is still some uncertainty about rainfall as cloud cover may persist across the District through the late morning and possibly into the afternoon. If the status dissipates by late morning, chances for isolated showers and thunderstorms will improve throughout the day, becoming scattered by the late afternoon. Storm motions will be from west to east around 15-20 mph. Storms will begin clearing by the early evening, with precipitation concluding by the mid to late evening. |
WORST CASE SCENARIO: There is a slight chance for training storms, which may produce moderate to briefly heavy rainfall up to 0.55” of rainfall in up to 10-15 minutes.
A LOOK AHEAD: On Saturday, mostly sunny morning skies will allow afternoon temperatures to climb into the 80s. Chances for isolated to scattered showers and thunderstorms improve during the afternoon and evening with a low chance for severe storms. On Sunday, high pressure ridging will begin building over the four corners region. Skies will be sunny with dry conditions and afternoon temperatures climbing into the upper 80s to low 90s. Hot and dry weather continues Monday with sunny skies and highs in the upper 80s to low 90s.
