An initial piece of the high slides eastward to off the SE Coast Fri thru Sat, with a second piece of high pressure building over the Mid Atlc region during Sun after an upper level trough tracks south of the area and off the SE coast late Sat night into Sun. Expect a sunny sky for Fri and Sat, and partly to mostly sunny sky on Sun. Highs on Fri will mainly be in the upper 40s to lower 50s. Lows Fri night will range from the mid 20 to around 30.
