the period...with scattered showers and isolated thunderstorms
developing late weekend and early next week.

Friday night through Tuesday...High pressure will remain
anchored off the southeast coast, as frontal boundary slowly
approaches from the west. Warm moist S/SW flow expected across
the region, and low level thickness values support highs 65-70
degrees along the Outer Banks, and upper 60s to upper 70s
inland. Overnight lows generally in the 50s. Weak shortwave
moves through the Carolinas Sunday, and could support an isolated
showers/tstm...though expect best chances west of the area with
better forcing. Similar set up for Mon with scattered convection
possible. Better precip chances Tue as main front and trough
move into the Mid-Atlantic and SE US. Will continue 20-40
pops...highest Tue.

pushing through late Tuesday night and early Wednesday. High
pressure will build in from the north Wed and Thu, as another
frontal system approaches late week. Continue slight chance pops

degrees cooler for Thu.

a non factor. Clear skies again on Friday and winds will slowly
