A cold front passed through the region in the overnight hours and has ushered in a cooler air mass to the Mid-Atlantic that will generally feature high temperatures in the 80’s during the next few days. High pressure builds into the area over the next 24 hours and it looks like it’ll stay in control through the upcoming weekend although a shower or thunderstorm can pop up from time-to-time. An upper-level trough and surface front enter the picture early next week raising the chance of showers and thunderstorms to the Mid-Atlantic region.

The current heat wave in the Mid-Atlantic region likely reaches a peak today with some spots along the DC-to-Philly-to-NYC corridor reaching the 100 degree mark for afternoon highs. Temperatures will remain quite hot on Wednesday, but likely a few degrees lower than today due to more abundant cloud cover ahead of an incoming cold frontal system. Occasional showers and thunderstorms are likely from later today through tomorrow night. Any thunderstorm during this next 36 hours or so can reach severe levels producing torrential rainfall, damaging wind gusts, and hail and, unfortunately, power outages are on the table. The passage of the cold front late Wednesday night will usher in a cooler air mass for Thursday and Friday and the overall weather pattern may not include any more in the way of extreme heat for much of the eastern half of the nation through the remainder of the month of July.

The frontal system that edged off the east coast early yesterday has stalled-out and it will act as a conduit for tropical moisture to ride up along during the next 24 hours or so. As a result, there will be occasional rain today, tonight and on Saturday and strong thunderstorms are possible along the way. Many area lawns welcomed beneficial rainfall on Wednesday night from strong thunderstorm activity and there can be an additional couple of inches of rain during the next 24 hours. In fact, as much as 3 or 4 inches of rain is on the table for some spots given this overall setup and flash flooding may become a concern. The threat of rain will diminish on Sunday and temperatures will climb noticeably with highs likely in the low-to-middle 90’s. It stays hot in the Monday-to-Wednesday time period with afternoon temperatures well up in the 90’s on each of those days. Looking ahead, the upcoming heat wave will likely come to an end by Thursday with the mid-week passage of a cool front.

Powerful storms rocked the Mid-Atlantic and Northeast US late yesterday and last night and cleansed the atmosphere of the high heat and humidity…at least for a few days. One of the ingredients involved with yesterday’s unstable atmosphere was a cold frontal system that has edged off the east coast On Thursday morning; however, we are not done yet with this system. That cold front will stall out later today right along the east coast and copious amounts of tropical moisture will ride up along its boundary zone from tomorrow into Saturday leading to additional showers and thunderstorms around here and some of the rain will be heavy. The high heat of recent days has backed off for the next few days, but it will return in full force in the Mid-Atlantic region for the Sunday, Monday, Tuesday, Wednesday time period and 100 degree highs are on the table.

Powerful storms hit the Mid-Atlantic region and Northeast US late yesterday and last night and this has cleansed the atmosphere of the high heat and humidity of recent days. A cold front was the main culprit of the instability and this system has pushed to a position just off the east coast; however, we’re not done with it yet. The cold front stalls out today along the coastline and tropical moisture will ride northward along the boundary zone on Friday increasing our chances once again for showers and thunderstorms. Some of the rain on Friday and Friday night can be heavy at times. The threat of showers and storms will continue on Saturday, but then decrease for the Sunday, Monday and Tuesday time period. The high heat of recent days will return in full force by early next week with afternoon high temperatures on Sunday, Monday, and Tuesday likely to be well up in the 90’s.

A rather widespread severe weather event is likely across much of the interior Northeast US and Mid-Atlantic region from this afternoon through tonight and tornadoes are certainly on the table. The main area of concern for tornadic activity extends from south-central Pennsylvania to upstate New York and Vermont...areas not usually thought of when it comes to tornado threats. The atmosphere is becoming increasingly unstable this afternoon given the combination of ingredients that includes high heat and humidity, low-level wind shear, and an incoming cold frontal system. The chance of showers and thunderstorms may decrease some on Thursday, but then it should rise again on Thursday night and Friday when moisture from a newly developing tropical wave enters the picture. This system will add some “fuel to the fire” by the end of the work week adding to chance for some heavy downpours on Friday along the eastern seaboard. The high heat of recent days will back off some on Thursday, Friday, and Saturday, but then will return in full force once again for Sunday, Monday, and Tuesday.

Humidity levels remain very high this morning in the Mid-Atlantic region with dew points - a direct measure of overall humidity - well up in the 70’s along much of the I-95 corridor. The high heat remains as well with temperatures likely to soar into the 90’s for afternoon highs making for very uncomfortable conditions indeed. The heat will back off some on Thursday, Friday, and Saturday, but is to return in full force by early next week with temperatures likely to soar well up into the 90’s on Sunday, Monday, and Tuesday.
In terms of rainfall, there will be an enhanced chance of showers and thunderstorms during each of the next few day and any rainfall can be very heavy at times. The combination of tropical moisture and a stalled-out frontal system will keep the atmosphere quite unstable through the second half of the week and when some daytime heating is added into the mix, the result is likely to be the development of numerous showers and thunderstorms during the afternoon and evening hours.
