Record Heat Wave Ends With Cooler Weather, Storms

A record-breaking heat wave across the Northeast and Mid-Atlantic, with cities such as New York, Philadelphia, Baltimore, and Newark setting new daily temperature records, is ending as a cold front brings cooler weather. Relief is expected by Thursday, with temperatures dropping from the upper 90s and 100s to the 70s and 80s, accompanied by increased cloud cover and chances for showers and thunderstorms. Some cities, including Philadelphia and Washington, D.C., may still approach record highs on Wednesday, but dangerous heat index values should subside by late week. The pattern will remain unsettled through the weekend, with intermittent rain and storms possible. The oppressive heat is not forecast to return immediately after the cold front passes. Temperatures are expected to gradually rise again next week but are not projected to reach the extreme levels seen during this event.
