Discussion

Powerful thunderstorms barreled through the DC-to-Philly-to-NYC corridor late yesterday causing widespread damaging wind reports and power outages (e.g., ~250,000 customers without power in SE PA). The passage of the surface cold front has lead the way to noticeably lower humidity today in the Mid-Atlantic region and there will be plenty of sunshine to go along with warm conditions.

The moderate humidity of today will give way to an extended stretch of high heat and humidity from later this weekend into at least the middle of next week. A very strong ridge of high pressure that has been stuck out west in recent days will move into the eastern states by later this weekend. This repositioning of the strong upper-level ridge will lead to high temperatures well up in the 90’s for multiple days all along the DC-to-Philly-to-NYC corridor...perhaps some spots can reach the 100-degree mark during this stretch.
