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.

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.

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.

The big story around here (and across much of the nation) will be the scorching heat that is on the way, and it can result in some record-breaking days. Temperatures peak later today in the middle 90’s, and they’ll surge on Friday and Saturday to near the 100-degree mark.

It has become uncomfortably humid and warm today across much of the Mid-Atlantic region following the progression of a warm frontal system that is pushing slowly to the north. This change in atmospheric conditions comes following a cool stretch of weather that featured high temperatures on Sunday, Monday, and Tuesday that were well below-normal for the middle of June. The atmosphere will quickly destabilize this afternoon and there are likely to be downpours and strong-to-severe thunderstorms impacting the I-95 corridor somewhere between 1pm and 8pm.
A surface cold frontal system will approach the Mid-Atlantic region from the northwest on Thursday, and this will combine with an upper-air disturbance to bring another threat of severe weather threat to the DC-to-Philly-to-NYC corridor. The likely timetable for severe thunderstorm activity on Thursday will again be 1pm-8pm, and there can be damaging wind gusts, hail, and even isolated tornadoes in any spot along the I-95 corridor. The cold front clears the coast by later tomorrow night and Friday will turn out to be a rather decent day featuring warm and dry conditions to end the work week.
Looking ahead, a very strong ridge of high pressure will build into the Mid-Atlantic region by the early part of next week and this will lead to high heat and humidity in the DC-to-Philly-to-NYC corridor from later this weekend into at least the middle of next week. After a very warm day on Saturday, temperatures are likely to soar into the 90’s on Sunday and then the first half of next week will feature high heat and humidity and 100 degrees will be a possibility in the DC-to-Philly-to-NYC corridor.

The big story around here (and across much of the nation) will be the scorching heat that is on the way for many locations. After temperatures peak later today in the middle 80’s, they’ll surge on Thursday to the upper 90’s and 100 degrees is on the table for Friday, Saturday, and Sunday.
