Discussion
The weather will remain quite nice through much of the day on Friday, but a tropical storm along the east coast will impact us here with rain and wind from later tomorrow night through much of the weekend. High pressure will slide off the New England coastline on Friday at the same time low pressure intensifies over the still very warm waters of the Southwest Atlantic. This system is likely to take on tropical characteristics as it moves in a general northward direction impacting the region with rain and wind on Saturday. The combination of the intensifying low pressure to the south and departing high pressure to the north will result in a tightening pressure gradient in the Mid-Atlantic region during this weather event. The result of this will be strong and persistent onshore winds and an increased chance of coastal flooding.
