The next 24-36 hours will be an active period in the Mid-Atlantic region with the threat for strong-to-severe thunderstorms both later today and again later tomorrow. A warm front lifted northward through the region earlier today and it has resulted in an increase in overall humidity levels as well as an increase temperatures now peaking in the low-to-middle 80’s. Another frontal boundary zone will approach the I-95 corridor region later in the day and this will set off some strong-to-severe thunderstorm activity…likely in the 4 to 10 PM time period. An even stronger front will approach from the northwest late tomorrow and this too is likely to generate some strong-to-severe thunderstorm activity in the Mid-Atlantic region. The good news is that all of this activity clears out early Friday - setting the stage for a stretch of nice weather from Friday into early next week.

A warm front is lifting through the region this morning and the afternoon will turn out to be a bit warmer than recent days with the chance of late day showers and thunderstorms. The chance of showers and thunderstorms will continue tonight and on Thursday as well as a weak cold frontal system arrives. Any storm that forms from later today through tomorrow night can be on the strong-to-severe side with gusty winds and heavy rainfall. An even stronger front should push through the area by early Friday paving the way for a nice stretch of weather beginning on Friday and continuing into early next week.

Clouds will dominate the skies again today in the Mid-Atlantic region and there is the chance for scattered shower activity to go along with the still rather comfortable temperature pattern. It’ll turn warmer and more humid on Wednesday following the passage of a warm front and the chance of showers and thunderstorms will return and that threat will continue on Thursday as well. A cold front is likely to push through at week’s end and is likely to set the stage for a nice Saturday and Sunday as high pressure builds into the area.

The comfortable temperatures that arrived in the Mid-Atlantic region on Sunday following the passage of a cold front will last for another couple of days; however, clouds will dominate the skies and there can be some shower activity later today, tonight and on Tuesday. It’ll turn warmer at mid-week and there will be the chance for some shower and thunderstorm activity, but a late week cold frontal passage could set the stage for a nice weekend.

The next 24-36 hours will be a very active period in the Mid-Atlantic region with the threat for severe thunderstorms from later this afternoon into tomorrow night and tropical downpours. There are even signs for a “bow echo” to form later today which could result in damaging wind gusts of > 60 mph (and possible power outages); especially, across eastern Pennsylvania and the southern and central parts of New Jersey. There is even the threat for isolated tornadoes later today in the I-95 corridor. Following all of this activity, a spectacular air mass for this time of year will ride in on stiff NW winds during the day Sunday and the very comfortable temperatures and humidity levels will stay around on Monday as well. Looking ahead, it’ll turn much more unsettled again around here on Tuesday and Wednesday with a renewed chance of showers and thunderstorms, and peaking even further down the road, there could be more tropical trouble to deal with in the eastern/southern states over the next week or two.

The next couple of days will be very unsettled in the Mid-Atlantic region with multiple systems to deal with as well as the tropical moisture associated with the remains of Hurricane Laura. There is the threat for strong-to-severe thunderstorm activity from later today through tomorrow evening and added tropical moisture will enhance the chance for heavy rain at times over the next 36 hours or so. Following all of this activity, a spectacular air mass for this time of year will ride in on Sunday on strong NW winds and those very comfortable temperatures and humidity levels will last into the first part of next week. It'll become quite unsettled again as we get to Tuesday and Wednesday of next week with a renewed threat of showers and thunderstorms each day.

Hurricane Laura came ashore last night near the town of Cameron in southwestern Louisiana initially estimated as a category 4 storm. It has pushed northward today into upstate Louisiana and has weakened along the way to a category 1 hurricane; however, it is still producing heavy rainfall and damaging wind gusts and will continue to do so into the state of Arkansas and parts of the Tennessee Valley. By the weekend, the remains of Hurricane Laura will interact with an incoming frontal system and upper-level trough to produce some heavy rainfall in the Mid-Atlantic region along with the potential for strong-to-severe thunderstorms. All of this activity will clear the east coast by Sunday and a spectacular air mass for late August will push into the Great Lakes, Northeast US and the Mid-Atlantic region.

Hurricane Laura came ashore last night in southwestern Louisiana as a category 4 storm and its remains will have an impact on the weather here on Saturday. A warm frontal system lifted northward through the region in the overnight hours and temperatures today will spike to the 90 degree mark. The sudden surge of heat will also come with a threat of late day or nighttime showers and thunderstorms and some of the storms can reach severe levels. Another frontal system will advance this way on Saturday and will combine with the remnants of Hurricane Laura as they push east from the Tennessee Valley region. As a result, rain is likely here on Saturday, some of it can be heavy at times, and there can be some strong-to-severe thunderstorm activity. All of this activity will push off the coast by Sunday and as high pressure returns so will the sunshine and the new air mass will be very comfortable for this time of year with pleasant temperatures and humidity levels.

Hurricane Laura has reached “major” hurricane status as a category 3 storm and it should intensify into a category 4 system this afternoon as it heads on a collision course with the Texas/Louisiana border region and expected landfall later tonight. Hurricane Laura intensified rapidly during the past 24 hours in a favorable environment of low wind shear and very warm sea surface temperatures and continues to intensify today - now just a bit under the required levels for a category 4 classification. After Hurricane Laura makes landfall later tonight, its story line will not be over. Its remains will push northward into the south-central states on Thursday producing heavy rainfall, severe weather, and damaging wind gusts. By the early part of the weekend, the remains of Hurricane Laura will turn to the east and get intertwined with a frontal system and an incoming vigorous upper-level trough to potentially produce some heavy rainfall in portions of the Mid-Atlantic region. Once off the Mid-Atlantic coast, the remnants of Hurricane Laura could actually re-intensify as it moves out over the warm waters of the western Atlantic.

A cold front passed through the region late yesterday and the result today will be quieter weather and very comfortable temperatures with afternoon highs near the 80 degree mark. This same front will turn around and push northward as a warm front later on Thursday and our temperatures are likely to spike into the 90’s for afternoon highs. After that, we’ll monitor the remains of Hurricane Laura as they could push northward into the south-central US later in the week and then eastward this weekend into the Mid-Atlantic region – potentially resulting in some heavy rainfall around here on Saturday and possible severe weather.
