The remnants of Barry will pass through the region later today and tonight and likely result in numerous showers and thunderstorms between 4 pm and midnight. There is the potential of torrential rainfall and some of the storms can reach severe levels with damaging wind gusts. It’ll be hot today with highs well up in the 90’s and then clouds may shave off a few degrees on Thursday, but then look out for the hottest weather of the year on Friday, Saturday, and Sunday with a run to 100 degrees possible for highs in that stretch. There can be scattered showers and storms later Sunday associated with a weak front and an even stronger front may bring late day showers and storms on Monday. This stronger front will usher in cooler air by next Tuesday with highs back in the 80's and there are signs for continued decent temperatures through the remainder of July. In fact, it could very well turn out that this stretch of excessive heat from Friday through Sunday will be the worst of the heat all summer long.

There are two big weather stories unfolding in the Mid-Atlantic region for the second half of the week and the upcoming weekend with the potential of some strong-to-severe thunderstorms and heavy rainfall over the next couple days as the remains of Barry pass through the region and then the hottest weather of the summer so far in the Friday into Monday time frame. Showers and thunderstorms are possible from tonight into Thursday in the DC-to-Philly-to-NYC corridor - any one of which can produce heavy rainfall. Once this large moisture field associated with Barry’s remnants pushes away from the area, an atmospheric blow torch will set up and cause temperatures to soar on Friday in the I-95 corridor and triple digits will be possible over the upcoming weekend. A strong cool front is likely to bring a round of showers and storms to the Mid-Atlantic late on Monday and more reasonable air is likely for the middle and latter parts of next week.

There are two big weather stories unfolding for the week and weekend in the Mid-Atlantic region with the potential of some heavy rainfall from later tomorrow into Thursday from the remains of tropical system Barry and then the hottest weather of the summer so far for the Friday, Saturday, Sunday time frame and perhaps even lasting into the early part of next week. Showers and thunderstorms are likely from later Wednesday into Thursday in the DC-to-Philly-to-NYC corridor mainly as a result of the remains of what was once Hurricane Barry and some of this rain can be heavy at times. Once this large tropical moisture field pushes away, the excessive heat will become the main story with mid-to-upper 90’s possible for highs on Friday, Saturday and Sunday and triple digit highs are certainly on the table.

There are two big weather stories unfolding for the week and weekend in the Mid-Atlantic region with the potential of some heavy rainfall at mid-week from the remains of Barry and then the hottest weather of the summer so far for the Friday, Saturday, Sunday time frame and perhaps even into the early part of next week. Showers and thunderstorms are likely from later Wednesday into Thursday in the DC-to-Philly-to-NYC corridor mainly as a result of the remains of Barry and some of this rain can be heavy at times. Once this large moisture field pushes away, the excessive heat will become the main story with mid-to-upper 90’s possible for highs in DC, Philly and NYC this weekend and triple digits is on the table.

Today will be rather comfortable in the Mid-Atlantic region with moderate humidity levels, but excessive heat is on the way for the upcoming weekend. After the decent start to the new work week, heat and humidity will build on Tuesday and there can be a few late day and/or nighttime showers and thunderstorms. The remains of Barry will enhance the chance for showers and storms from late Wednesday into Thursday and some of this rain can be heavy at times. Once that moisture pushes away, excessive heat will build into the Mid-Atlantic region with mid-to-upper 90's possible here for highs on Friday, Saturday and Sunday and triple digits is on the table...certainly the hottest weather so far this summer season.

A strong cold front is sliding through the region this morning and it could help to produce a residual shower or thunderstorm in the area, but the overall trend will be for improving conditions. The weekend should turn out to be pretty decent with plenty of sunshine each day, quite warm conditions and only moderate humidity levels. Meanwhile, the central Gulf coast is bracing for a possible direct hit of a hurricane or strong tropical storm as “Barry” slowly drifts towards the Louisiana coastline. This tropical system will pound the central Gulf coast with tremendous rainfall amounts over the next couple of days as it’ll be a slow mover and the Mississippi River is already at high levels which will only exacerbate the flooding potential. Eventually, the remains of “Barry” may actually have an impact here in the Mid-Atlantic region as it could take a path from the central Gulf to this area during the next several days.

A broad area of low pressure is drifting westward this morning over the Gulf of Mexico and there is not yet a well-defined center of circulation. As atmospheric conditions become more favorable and the system moves over warmer-than-normal water, intensification will become more likely and tropical storm status could be attained by later tonight or early tomorrow and perhaps (weak) hurricane status can be reached by later tomorrow night. A turn to the northwest by the early part of the weekend could bring this tropical system into central Louisiana and it’ll likely remain a relatively slow-mover raising the chances for substantial amounts of rainfall across southern Louisiana and parts of Mississippi as well over the next few days. Elsewhere, there is a threat this afternoon and tonight in the I-95 corridor for strong-to-severe thunderstorms – any one of these storms can bring heavy downpours to an already-soaked part of the country.

A strong cold front will approach the region later today and bring with it isolated morning showers and thunderstorms and likely a round or two of afternoon and evening showers and thunderstorms. Any PM thunderstorm can be strong-to-severe with heavy rainfall and potential localized flash flooding. The front drops southeast of here on Friday, but a residual shower or thunderstorm cannot be ruled out and the end of the work week will continue to feature quite warm conditions. Elsewhere, intensification was slow overnight in a tropical system now over the Gulf of Mexico, but that should become more rapid over the next 24 hours. As such, it is likely this system will reach named tropical storm status later today or tonight (to be called Barry) and it could reach hurricane status by the weekend. It appears this system will drift west for much of today and then take a turn to the north-to-northwest by the weekend and perhaps end up making landfall in central Louisiana. Tremendous rainfall amounts are likely with “Barry” in the central Gulf coast region; especially, over southern Louisiana where more than a foot can fall over the next couple of days and the Mississippi River is already running at high levels from springtime rains and snow melt. Looking ahead, it is possible that the remains of Barry has an impact here in a week or so as it potentially takes a track from the southern states into the Mid-Atlantic region.

High pressure will remain in control of the weather around here for another day before it shifts off the eastern seaboard opening the door for low pressure and its associated cold front to impact the region late tomorrow. It’ll be quite warm again today with plenty of sunshine and overall humidity will become more noticeable on Thursday ahead of this next frontal system. That front may result in some strong-to-severe thunderstorm activity here later tomorrow and tomorrow night before clearing the east coast at the end of the work week. Elsewhere, a tropical system now over the northern Gulf of Mexico is very likely to intensify into a named (Barry) tropical storm by the end of the week. This developing system could very well have a direct impact this weekend on the Texas/Louisiana border region as a category 1 or 2 hurricane...we’ll continue to closely monitor the situation.

High pressure will control the weather around here for the next couple of days before shifting off the east coast later in the week. It’ll be quite warm with plenty of sunshine today and tomorrow and then overall humidity will become more noticeable on Thursday ahead of the next frontal system. That front may result in some strong-to-severe thunderstorm activity here late Thursday or Thursday night before clearing the coast at the end of the work week. Elsewhere, a tropical system could intensify into a named tropical storm (Barry) over the Gulf of Mexico by later in the week and we’ll closely monitor the situation. Looking ahead, signs point to a heat wave next week in much of the Midwest, Northeast and Mid-Atlantic region.
