A coastal storm that has been impacting much of the Atlantic seaboard during the past few days will finally weaken and exit off to the east later today. Weather conditions will be slow to improve in the Mid-Atlantic region, but the mid-week should feature some sunshine in the area ahead of the next cold frontal system. That cold front will pass through the region on Wednesday night and it’ll usher in a chilly air mass with temperatures on Thursday likely to struggle to climb much past the 60-degree mark for afternoon highs despite plenty of sunshine…there will be a noticeable northwest wind as well.

Low pressure off the east coast will continue to influence our weather today with cloudy skies, breezy and cool conditions, and occasional showers. This coastal system will weaken and move out to sea on Tuesday and improvement in the weather will begin to take place in the Mid-Atlantic region. High pressure builds in by the middle of the week and generates comfortably cool and dry conditions for much of the second half of the week.

Lots of players are on the field as we begin the weekend with one upper-level low over the Great Lakes that is dropping slowly to the southeast and a second wave of energy in the southern stream that is helping to spin up a surface low pressure system off the southeast US coast. In addition, there is a strong high-pressure system to our north that continues to shift slowly offshore as we begin the weekend. The combination of the high to the north and low to the south is already producing an onshore flow of air in the Mid-Atlantic region and this will persist for the next few days potentially leading to significant coastal flooding/beach erosion from Long Island-to-New Jersey-to-the Delmarva Peninsula. While there can be some heavy showers and strong wind gusts across inland areas during the next few days, rainfall amounts will be much more limited with the worst impact from this developing storm system confined to coastal sections.

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.
