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.

In terms of some specifics for the NYC metro region, estimates are for east-to-northeast wind gusts of 50-60 mph along coastal sections, 30-50 mph inland...3+ inches of rain along coastal sections, and 1-3 inches inland.

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 well down in the 30’s in many 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.
