High pressure over the Northeast US will continue to dominate the weather scene around here as it migrates slowly eastward. A frontal system will approach the region tomorrow night and this is likely to result in a renewed threat of scattered showers and thunderstorms. That same front will tend to stall out in the eastern states at week’s end and the result will be a continuing chance for showers and thunderstorms on Friday and Friday night. "Bermuda-high" type weather will develop around here this weekend and it could get quite hot with highs in the low-to-mid 90's.

High pressure builds into the area today and it should have an influence around here through the remainder of the week. Temperatures will continue to be at seasonably warm levels and the chance of showers and thunderstorms will be quite minimal for the next couple of days. Comet NEOWISE is now visible in the evening sky and viewing conditions should be quite good again tonight – look straight down and a little bit to the right from the Big Dipper to near the horizon in the northwest sky about an hour or so after sunset (i.e., around 9:30 PM)…may need binoculars.

First, there was Comet ATLAS in April which disappointed sky watchers as it broke apart into pieces. Then there was Comet SWAN in May which also disintegrated. And now we have a third comet named NEOWISE and this one is coming through and could be visible until mid-August. In recent days, this comet has dazzled sky watchers and may be the brightest comet since 1997 (Hale-Bopp). The comet will be easier to see in coming days as it climbs in the evening sky towards the Big Dipper (aka Ursa Major).

A weak front sits off the coast this morning and there is a chance today for isolated showers and thunderstorms. High pressure builds into the area on Tuesday and should have an influence here through the remainder of the week. Temperatures will start off the week at seasonably warm levels with highs in the upper 80's, but then will climb into the 90's later in the week. One final note, Comet NEOWISE has now become visible in the evening sky – look low to the northwest an hour or so after sunset.

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.
