| A round of storms initiated along the foothills this afternoon bringing some moderate to brief heavy rainfall with 0.30”-0.75” total in 10-30 minutes. These storms produced a strong gust front that moved eastwardly through the District with gusts up to 35mph. This gust front pushed through the District and resulted in a strong line of storms east of the District. This line of storms will not move very much as storms pulse up along the gust. This line of storms could potentially produce an additional gust front which could move west and back into the District. This will result in a slight chance for storms to develop within the District, favoring eastern portions of the District at this time. This potential will keep Message 1’s valid until the evening as the threat of moderate to heavy rainfall remains. Storm intensities will decrease after sundown with a few off and on showers possible through midnight. |
WORST CASE SCENARIO: A strong stationary thunderstorm or training of thunderstorm cells will have the potential to produce 1.20” total in 30-60 minutes.
A LOOK AHEAD: Not much overall change in the upper-level pattern tomorrow will bring another chance for afternoon and evening showers/thunderstorms. Slightly less overall moisture aloft will decrease chances for moderate to heavy rainfall for the District tomorrow. Similar high temperatures in the low 90s. The heat returns Sunday with highs jumping back into the upper 90s. A slight chance for high-based showers, mainly along the foothills in the afternoon and early evening. Hot and dry Monday with highs in the upper 90s.
