Heavy rain bands are rotating around Tropical Storm Fay at this hour and extending northwestward into eastern Pennsylvania, northern New Jersey and southeastern New York. There has already been a boat load of rain over the Delmarva Peninsula with several inches in some spots and flooding has been prevalent in some Delaware beach towns such as Bethany Beach. Tropical Storm Fay will continue to push in a general northerly direction over the next several hours though it could bobble around at times in slightly different directions. The storm’s center is likely to push through New Jersey from south-to-north later today and then continue northward tonight into the Hudson Valley region of New York State.

Bands of showers are rotating around Tropical Storm Fay which is currently situated near the southern tip of the Delmarva Peninsula. The immediate DC metro region will be outside the zone of the heaviest rainfall with the western edge of this axis likely to be the western shore of the Chesapeake Bay and northeastern Maryland. The Delmarva Peninsula is being inundated with heavy rainfall from TS Fay and there are reports of flooding already in places like Bethany Beach. By later today and early tonight, the low pressure system is likely to push northward into the Hudson Valley region New York State bringing significant rainfall to portions of the interior Northeast US. The weekend will remain somewhat unsettled around here with the chance of scattered showers and thunderstorms and an upper-level trough will likely result in an additional rain threat on Monday and Tuesday. Later next week, it could turn pretty hot later across the Great Lakes, Northeast US and Mid-Atlantic region.

The main focus today is on a low pressure system over the coastal sections of North Carolina as it poses a threat for heavy rainfall on Friday in the eastern Mid-Atlantic region. This system is likely to push to the northeast during the next several hours out over the warm waters of the western Atlantic and then make a move in a more northerly direction likely reaching a position over the southern half of the Delmarva Peninsula by early tomorrow. There is a good chance that when this system moves out over the ocean later today, it’ll intensify enough to become a “named” tropical storm (would be “Fay”). Whether or not it becomes a "named" storm, it has the potential to produce very heavy rainfall on Friday in the eastern part of the Mid-Atlantic region along with quite gusty winds along coastal sections.

Scattered showers and thunderstorms continued to plague the Mid-Atlantic region on Wednesday, but today will present only a slight chance of rainfall as we have a brief break in the action. Attention now turns to the Outer Banks of North Carolina as low pressure over that region is likely to push to the northeast later today and then move in a more northerly direction reaching the southern part of the Delmarva Peninsula by early tomorrow. With this expected move out over the warm waters of the western Atlantic, there is a chance for intensification and a possible "naming" of the storm by NOAA's National Hurricane Center later today or tonight as it potentially reaches tropical storm status (it would be "Fay"). Whether or not "naming" of the storm takes place, heavy rainfall is on the table for Friday across the Delmarva Peninsula, but the DC metro region could end up being just to the west/southwest of that heavy rainfall threat zone...stay tuned, still a close call. The departure of this coastal storm on Saturday will not be the end of the wet weather pattern in the eastern US. An impressive upper-level trough should form by later in the weekend likely leading to more rainfall around here during the first half of next week.

Scattered showers and thunderstorms continue to plague the Mid-Atlantic region at mid-day and this threat will continue into tonight. On Thursday, attention will turn to the Outer Banks region of North Carolina as this is where low pressure is likely to be located early in the day. This system is then likely to push to the northeast out over the warm waters of the western Atlantic and then make a move northward reaching a position near the southern part of the Delmarva Peninsula by early Friday. There is a chance when this system moves over the open waters of the western Atlantic, it’ll intensify enough to become a “named” tropical storm by NOAA’s National Hurricane Center. Whether or not it becomes a "named" storm (it would be “Fay”), it has the potential to produce very heavy rainfall on Friday in the eastern part of the Mid-Atlantic region along with gusty winds and strong rip currents in the western Atlantic Ocean. The departure of this coastal storm on Saturday will likely not be the end of the wet weather pattern in the eastern US. An impressive upper-level trough should form by later in the weekend likely leading to more rainfall into the first half of next week.

The threat for scattered showers and thunderstorms will continue today and tonight in the Mid-Atlantic region and then attention will turn to the Southeast US as low pressure pushes through the Carolinas and heads toward the warm waters of western Atlantic Ocean. This low pressure system is likely to take a turn to the north later in the week and ride up along the Mid-Atlantic coastline or just to its east. There is a chance that if the low pressure system spends considerable time out over the water, it could actually intensify and become a "named" tropical system. Whether or not it becomes a "named" storm, it has the potential to bring some heavy rainfall on Friday to the eastern part of the Mid-Atlantic and strong rip currents to the ocean, but it is a bit early to tell if most of the heavy rain would fall to the east of here. The departure of this coastal low on Saturday will likely not be the end of the wet weather pattern in the eastern US. An impressive upper-level trough should form by later in the weekend likely leading to more rainfall around here into the first half of next week.

There was significant rainfall in the Mid-Atlantic region on Monday with as much as 4-8 inches just to the southeast of Washington, D.C. and grounds are very well-saturated in many spots. While there can be some shower and thunderstorm activity later today, it should not be nearly as widespread nor as intense as to what took place late yesterday. The threat for scattered showers and thunderstorms will continue on Wednesday and then attention will turn to the Southeast US as low pressure slowly pushes through the Carolinas and heads toward the western Atlantic Ocean. This tropical/sub-tropical low pressure system is likely to then take a turn to the northeast and ride up over or just to the east of the the Mid-Atlantic coastline. The result could be some heavy rainfall on Friday - likely along and to the east of Route I-95 - and strong rip currents are likely to form in the ocean as well with gusty winds. The departure of this coastal low on Saturday won’t be the end of the wet weather pattern for the eastern states as an impressive upper-level trough is likely to develop by later in the weekend leading to more rainfall into the early part of next week.

Summer-like weather will continue this week with quite warm and humid conditions and additional chances for showers and thunderstorms. While it may be hard for the atmosphere to rebound from yesterday's "hard work", there is the chance for more showers and thunderstorms this afternoon and evening and any shower or storm that forms can produce heavy rainfall. Temperatures should once again reach the 90's later today and high humidity levels will make it quite uncomfortable. Later this week, a storm will pull out of the Southeast US and ride up along the eastern seaboard. This scenario could bring heavy rainfall to at least portions of the Mid-Atlantic region along and east of I-95 from late Thursday night into early Saturday - something to closely monitor given the already well-saturated grounds in many spots. More showers and storms are possible around here later this weekend and into the early part of next week.

A summer-like week is in store for the metro region with hot, humid conditions and multiple chances for showers and thunderstorms. In fact, there is a good chance of showers and thunderstorms later this afternoon and evening as a weak front arrives and some of the late day/evening storms can be on the strong-to-severe side with torrential downpours. Temperatures today are likely to climb into the low-to-mid 90's for highs and it'll stay hot and uncomfortable for much of the week. Later this week, a storm will pull out of the Deep South and potentially ride up along the eastern seaboard. If so, this system would enhance chances for heavy rainfall in the Mid-Atlantic region on Thursday night and Friday.

Low pressure in the upper part of the atmosphere is shifting off the coast of the Northeast US today and this should result in rain-free conditions in the Mid-Atlantic region. There will be plenty of sun today and afternoon temperatures should peak near the 90 degree mark. It’ll get hotter on Friday with temperatures likely to climb into the middle 90’s and there is the chance for some afternoon/evening shower and thunderstorm activity as a back door cool front approaches the area. The passage of the back door cool front should knock a few degrees off of temperatures for the weekend, but we'll still climb to near the 90 degree mark for afternoon highs on both days. There should be some sunshine on both weekend days, but an afternoon or evening shower or thunderstorm cannot be ruled out on either Saturday or Sunday.
