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.

The big story around here (and across much of the nation) is the scorching heat that can result in record-breaking highs around here today, tomorrow, and on Sunday. Temperatures should peak later today near 100 degrees, and they’ll surge on Saturday and Sunday well up into the 90’s. Relief is on the way for early next week with noticeably cooler conditions expected for Monday, Tuesday and Wednesday along with the chance of showers and thunderstorms.

The big story across much of the nation is the influx of high heat and humidity and the southeastern states will be impacted as well. After highs today not far from 90 degrees, temperatures will then surge well up into the 90’s over the weekend and early next week and humidity will be a very noticeable factor as well.

Many ingredients are coming together to raise the chance of severe weather later this afternoon and evening in the Mid-Atlantic region. A strong surface cold front, high heat and humidity, and an impressive upper-level disturbance will help to destabilize the atmosphere this afternoon and there are likely to be strong-to-severe thunderstorms impacting the I-95 corridor somewhere between 2pm and 8pm. The cold front clears the coast by late tonight and Friday will turn out to be a less humid day featuring plenty of sunshine and warm conditions.
The moderate humidity expected on Friday will give way to an extended stretch of high heat and humidity in the Mid-Atlantic region from later this weekend into at least the middle of next week. A very strong ridge of high pressure will build into the eastern states, and this will lead to high temperatures well up in the 90’s for multiple days all along the DC-to-Philly-to-NYC corridor.

The atmosphere will become quite unstable later today with the approach of a surface cold frontal system combined with a disturbance in the upper part of the atmosphere. As a result, the chance for afternoon and evening showers and thunderstorms will be high and any thunderstorm that forms can be severe with heavy rain and damaging wind gusts. There is also that chance in this expected thunderstorm activity for large hail and isolated tornadoes cannot be ruled out. Temperatures today will climb to uncomfortably warm levels near 90 degrees and the humidity will be a very noticeable factor as well.
After a sunny and warm day to end the work week, very strong high pressure ridging in the upper part of the atmosphere will push eastward this weekend. This system will end up directly overhead in the Mid-Atlantic/Northeast US by the early part of next week and likely stay put until at least the middle of next week. As a result, high heat and humidity is on the way for an extended period of time from later this weekend into at least the middle of next week.

The big story across much of the nation in coming days will be the influx of intense heat and the southeastern US will be impacted as well. After highs today in the mid-to-upper 80’s, temperatures should climb to 90 degrees on Friday, and then surge well up into the 90’s over the weekend and humidity will be a very noticeable factor as well.
