A cold front is pushing through the region this morning and a reinforcing comfortable air mass for early August will move into the Mid-Atlantic as we begin a new work week. In fact, the overall weather pattern will result in below-normal temperatures in much of the eastern half of the nation for much of this week with an upper-level low stationed over the northeastern quadrant. There will be a lot of moisture across the Gulf coast and southeast US in coming days and some of this may try to push northward later in the week.

There have been multiple reports of damaging winds and hail in the metro region from the severe thunderstorm activity of late yesterday and multiple tornadoes struck Bucks County in southeastern Pennsylvania and parts of New Jersey. All of this activity took place upon the arrival of a strong cold that is in the process of moving off the coastline. High pressure builds into the region as we end the work week with a much more comfortable air mass in place including the lowering of humidity and the weekend will actually start off with temperatures not far from 60 degrees –below the norm for the last day of July. Another cold front could produce more showers and storms here late in the weekend and its early week passage will usher in more comfortable air for the bulk of next week – the first full week of August.

The overall weather pattern is evolving to one that will bring very comfortable air to the Mid-Atlantic region as we end the month of July and begin the month of August, but it is going to be rough going to get to that point as there is the threat for severe weather later today into early tonight. A complex of severe thunderstorms blasted through Wisconsin in the overnight hours in a northwest-to-southeast direction and this line has held together and will push into the Mid-Atlantic region later in the day. There is the potential this afternoon and evening for severe weather in the Mid-Atlantic region to include all the weather parameters from hail-to-heavy rain-to-isolated tornadoes. Following the passage of a strong cold front, comfortable air with low humidity will push in on Friday riding in on stiff NW winds and the comfortable weather pattern will last through much of next week as well – the first full week of August.

The overall weather pattern is evolving to one that will bring comfortable air to the DC metro region as we end the month of July and begin the month of August, but it may a rough time getting to that point with severe weather a threat later today and early tonight. A complex of severe thunderstorms blasted through Wisconsin in the overnight hours from northwest-to-southeast and this line will play a key role later today in the Mid-Atlantic region. Indeed, there is the potential for severe weather to include all the parameters from hail-to-heavy rain-to-tornadoes. Following the passage of a strong cold frontal system, very comfortable air will push in on Friday and the comfortable weather pattern will last through much of next week as well – the first full week of August.

The overall weather pattern is evolving to one that will bring very comfortable air to the Mid-Atlantic region as we end the month of July and begin the month of August, but it may a rough time getting there with severe weather a threat on Thursday. A complex of severe thunderstorms will blast through Wisconsin in the overnight hours from northwest-to-southeast and this line will play a key role on Thursday in the Mid-Atlantic region. There is the potential later tomorrow for severe weather in the Mid-Atlantic region to include all the parameters from hail-to-heavy rain-to-tornadoes. Once the cold frontal system passes through the region, quite comfortable air will push in on Friday riding along on stiff northwest winds and the comfortable weather pattern will last through much of next week as well – the first full week of August.

A couple of cold frontal systems will play a role in our weather during the next several days and the end result in the Mid-Atlantic region is quite likely to be some pretty comfortable air for the end of July and the beginning of August. The first front will arrive later tomorrow and it could bring some strong thunderstorm activity into the area and then comfortable air will follow for Friday and Saturday with lower humidity levels. A second front should arrive early next week and it too should usher in some pretty comfortable air for much of the first week of August.

While much of the nation from the Northern Plains to the Pacific Northwest has experienced hotter-than-normal weather this month, the Mid-Atlantic region has enjoyed a nearly normal month in terms of overall temperatures. In fact, it appears the last couple of days of July can include some below-normal temperatures in much of the Mid-Atlantic region and the first week of August could turn out to be cooler-than-normal in much of the eastern US. In addition to the potential for cooler-than-normal temperatures in the Mid-Atlantic region next week, we’ll have to watch out for the possibility of a coastal storm.

The overall weather pattern across the nation over the next few days will feature upper-level ridging centered over the Northern Rockies and an upper-level low over southeastern Canada. As a result, it’ll be hotter-than-normal from the Northern Plains to the Pacific NW and the DC metro region should reach 90+ degrees over the next few days. Temperatures will trend downward as we head into the weekend and there are signs for some pleasant air next week as we begin the month of August.

The north-central and northwestern parts of the nation will experience warmer-than-normal conditions this week as upper-level high pressure ridging intensifies over that region. In the Northeast US, the week will start off very warm with highs at or above 90 degrees through mid-week, but more comfortable air is likely to push here by the late week. Elsewhere, monsoonal moisture will continue to push into the “Four Corners” region of the Southwest US resulting in additional heavy rainfall for that part of the nation.

A cool front passed through the region on Wednesday night and ushered in a more comfortable air mass for the latter part of July. In addition, the new air mass helped to “cleanse” the atmosphere of the smoke-caused haze that dominated the skies earlier in the week. Temperatures and humidity will remain on the bearable side for the next couple of days, but it’ll get hot and more humid for the Sunday-to-Tuesday time period and there will be an increasing chance of showers and storms.
