Southwesterly flow aloft will continue to dominate over the region today bringing hot, breezy and mostly dry conditions across the District. High temperatures will once again hit the low 90’s in some spots today under partly cloudy skies. Mild and dry conditions to start the day, with winds picking up into the afternoon, with gusts peaking between 20-30mph from the WSW with winds decreasing significantly after sunset. A slight chance late this afternoon and evening for a few high-based showers/isolated thunderstorms with the best chance between 6-10pm. Most if not all precipitation will struggle to reach the surface today as long as dew points at the surface mix out through the morning. If dew points remain elevated, a better chance for impactful rain will be possible this afternoon and evening, however, chances for good storm development will remain minimal this afternoon and evening. Overnight will be mild with lows dropping into the low to mid 50’s for the plains with mid to upper 40’s along the foothills.

STORM RAINFALL POTENTIAL AND DURATION: Typical rain showers will produce a TR-0.10” total, in 10-30 minutes. A weak to moderate thunderstorm will produce 0.10-0.30” total, in 10-30 minutes.

WORST CASE SCENARIO: A moderate to strong thunderstorm is able to develop and could potentially produce up to 0.6” total in 45-60 minutes.

A LOOK AHEAD: A better chance for showers/thunderstorms Thursday as a disturbance moves through the region. An uptick in overall moisture, combined with upper-level support will likely result in a chance for heavy rainfall Thursday. Similar conditions remain in place Friday, although upper-level shifts northwesterly, leading to slightly less chances for heavy rainfall as storms expected to increase in speed during the day and into the evening Friday. This weekend will remain fairly active with afternoon and evening showers/thunderstorm chances both Saturday and Sunday.
