Weather from NBC Storm Team 4 — Updated 4:22 a.m., July 30, 2015

Thursday will be a Storm Team 4 Weather Alert day due to the heat and the potential for strong to severe thunderstorms. Heat with high humidity will peak Thursday. Temperatures remain in the 90s thereafter with low humidity until next Wednesday.

We rose to 92 at Reagan National Wednesday afternoon, our sixth day in a row at 90 degrees or above. This current heat wave may continue for another 6 days — we will get a break from the humidity Friday and into the weekend, but it will stay rather hot.

A weak front will approach from the west Thursday, bringing the threat of strong to severe thunderstorms in the afternoon and evening. The main threats will be damaging winds and torrential rainfall, and we are expecting the worst of the weather to occur between 1 p.m. and 8 p.m. The front will push through Thursday night, bringing a welcome break from the humidity for Friday and into the weekend.

THURSDAY: Partly to mostly cloudy, hot and humid. A chance of a morning shower, then afternoon and evening thunderstorms. Storms may become severe, with damaging wind gusts and hail. Flooding downpours are also possible.

Highs in the low to mid-90s; the heat index may reach 100
