Detailed Forecast


Synopsis: High pressure will build into the eastern U.S. through midweek. A backdoor cold front will move south into the area late tonight and Wednesday before lifting northward as a warm front on Thursday and Friday. A weak cold front will approach the East Coast near the end of the week into the weekend, but high pressure in the Southeast will likely aid in its stalling and eventual dissipation.
