High-pressure continues to build over the District this morning, slowly moving easterly resulting in upper-level winds shifting northwesterly this afternoon. This shift in upper-level dynamics will effectively help storm motions today from the NW to SE between 10-20mph, limiting any long-lasting moderate to heavy rainfall. However, with dew points still in the mid to upper 50s, a couple of stronger storms will have the potential to produce outflow boundaries today, bringing another chance for some erratic/stationary storm motions leading to another chance for a few isolated heavy showers this afternoon and into the early evening. The best chance for storm activity this afternoon and early evening will be between 2-9pm. The initial round of storms will likely be the strongest during the afternoon today, bringing the best chance of impactful rainfall producing storms, possibly severe, with another chance for an additional round of showers in the evening before skies clear through the overnight. Temperatures overnight will drop into the upper 50s to around 60 degrees on the plains with upper 40s to around 50 degrees along the foothills.

STORM RAINFALL POTENTIAL AND DURATION: Typical showers and isolated thunderstorms will produce a 0.05-0.40” total in 10-30 minutes. A moderate to strong/severe shower/thunderstorm will produce 0.40-0.80” total in 10-30 minutes.

WORST CASE SCENARIO: A strong, stationary thunderstorm, or training of thunderstorm cells will have the potential to produce up to 1.60” total in under 30 minutes.

A LOOK AHEAD: Conditions start to dry out Tuesday with just a typical chance for springtime afternoon showers/isolated thunderstorms. Wednesday is expected to be even drier with minimal, if any, chance for precipitation at this time across the District.
