Low pressure is going to intensify significantly this weekend near the Southeast US coastline, induced by a frontal boundary zone that slides into the region, and energized by an upper-level trough that drops southeast across the Great Lakes. It appears likely that this strong coastal storm will then push far enough to the north to have an impact on the Mid-Atlantic region all the way from later Saturday into late Monday. The worst impact will be along coastal sections where rain will be heaviest, winds will be strongest, and the threat of coastal flooding/beach erosion will be high due to a prolonged period of onshore flow.

Low pressure is going to intensify significantly this weekend near the Southeast US coastline, induced by a frontal boundary zone that slides into the region and energized by an upper-level trough that drops southeast across the Great Lakes. It appears increasingly likely that this strong coastal storm will then push far enough to the north to have an impact on the Carolinas, Mid-Atlantic, and Northeast US all the way from later Saturday into late Monday. The worst impact will be along coastal sections where rain will be heaviest, winds will be strongest, and the threat of coastal flooding/beach erosion will be high due to a prolonged period of onshore flow.

Canadian high pressure will take control of the weather today leading to the coolest day so far this fall season and the possibility of the first frost late tonight in many suburban locations. Radiational cooling conditions will be quite good in the overnight hours as high pressure parks overhead and generates clear skies, light winds, and overnight temperatures down in the 30’s in some areas.
Looking ahead to the weekend, strong low pressure system will form off the Southeast US coastline and produce heavy rainfall and strong winds for the coastal Carolinas including - once again - the Outer Banks of North Carolina. This strong coastal storm system is then likely to push northward to or just off the Mid-Atlantic coastline by later in the weekend...likely resulting in an impactful rain and wind event for the Mid-Atlantic region from late Saturday night-to-Monday.

Low pressure is going to intensify significantly this weekend near the Southeast US coastline, induced by a frontal boundary zone that slides into the region. It appears quite certain that this strong storm will then push far enough to the north to pound away at the coastal Carolinas with heavy rainfall and strong winds...another highly impactful event for the Outer Banks of North Carolina. After that, odds continue to increase that this weekend storm system will then push to the northern Mid-Atlantic coastline - act as a classic Nor’easter - and bring impactful rain and wind to coastal sections for an extended period of time. By early next week, the northward progress of this storm system will likely come to an end as strong high pressure builds across southeastern Canada (“confluence”) acting as a barrier in the atmosphere. As a result, the storm should turn east or it may even loop back around for awhile early next week near the Mid-Atlantic coastline before ultimately pushing out to the open waters of the western Atlantic.

Lingering showers this morning as a cold front works its way through the region and it’ll turn noticeably cooler for the remainder of the week following the unseasonably warm start on Monday and Tuesday. Canadian high pressure will take control of the weather by tomorrow and it’ll lead to excellent radiational cooling conditions later tomorrow night with clear skies and light winds. As a result, the first frost of the season is possible in some N/W suburbs by early Friday morning with overnight lows down in the 30’s.
Looking ahead to the weekend, strong low pressure will form over the western Atlantic Ocean and likely produce heavy rainfall and strong winds for the Carolinas. This system has an increasing chance of impacting the Mid-Atlantic region as well with some heavy rainfall and strong winds, but an “escape” to the east-northeast and away from the Mid-Atlantic coastline is still a scenario that is on the table. The time period of concern for the Mid-Atlantic region for rain and wind would be from Saturday night to Monday.

Low pressure is going to intensify significantly this weekend near the Southeast US coastline, induced by a frontal boundary zone that slides into the region. It appears quite certain that this strong storm will then push far enough to the north to pound away at the coastal Carolinas with heavy rainfall and strong winds. It is a little less certain if this strong storm can then extend far enough to the north along the eastern seaboard to produce heavy rainfall and strong winds in the Mid-Atlantic region, but that scenario is certainly on the table. Whether this system becomes a named tropical storm by NOAA’s National Hurricane Center is still too early to say; however, the effects could be much the same along coastal sections of the Carolinas and potentially to the Mid-Atlantic region...namely with heavy rainfall and strong winds...a kind of classic autumnal Nor’easter. Some of the key players involved include strong high-pressure ridging which will set up over southeastern Canada and a cold front that will slide to the southwestern Atlantic Ocean by the end of the week and help to act as a catalyst for the significant intensification of surface low pressure.

Clouds will increase here today ahead of an approaching cold front which will bring us some beneficial rainfall from tonight into early Wednesday...perhaps a thunderstorm included in the mix. The unseasonably warm temperatures that started the week will be replaced by noticeably cooler conditions for the second half as Canadian high pressure takes control following the cold frontal passage. In fact, the first frost of the season will be possible on Thursday night in some far N/W suburban locations with overnight lows in the 30’s. Strong low pressure is likely to form over the western Atlantic Ocean later this weekend and threaten the Carolinas with some heavy rainfall and strong winds…potentially a threat northward into the Mid-Atlantic region.

Low pressure is likely to rapidly intensify this weekend over the southwestern Atlantic Ocean and it is a threat for heavy rainfall and strong winds along coastal sections of the Carolinas and potentially to the Mid-Atlantic/Northeast US. Whether this system becomes a named tropical storm is too early to say; however, the effects could be the same along parts of the eastern seaboard…namely with heavy rainfall and strong winds likely in the Saturday night to Monday time period. Some of the key players involved include strong high-pressure ridging which will set up over southeastern Canada and a cold front which will slide to the southwestern Atlantic Ocean later in the week and help to act as a catalyst for the intensification of low pressure.

The main weather event of the next few days in the Mid-Atlantic region will be a cold frontal passage that takes places from later tomorrow night into the day on Wednesday. This front should be accompanied by showers and isolated thunderstorms that’ll break the dry spell of recent days. After a warm start to the work week with above-normal temperatures, cooler-than-normal conditions are likely during the second half. Low pressure off the eastern seaboard may become the main player to watch this weekend with the possibility of some rainfall around here by the time we get to Sunday and Monday.

A cold front passed through the region last night, but will linger off the coast for awhile and create some unsettled conditions across the Mid-Atlantic for the next few days. As a result, clouds will be rather plentiful on Friday, Saturday and Sunday and a few showers cannot be ruled out on each day. Strong high pressure will build into southeastern Canada early next week and we’ll have to monitor the movement of tropical systems over the western Atlantic for potential impact along the east coast.
