As of 340 AM Saturday, high pressure should build in from the west tonight with winds gradually dropping to 5 knots or less by Sunday morning.

Winds will back to the WNW with building hts and in response temps will moderate back into the upr 60s (mid 60s OBX) across the FA. Wall to wall sunshine expected with very dry column. Another cool night Sun night with lows dropping back into the mid/upr 40s interior to 50s on the beaches. Monday...A brief warmup back to above climo on Mon as flow backs to the W in response to approaching reinforcing short wave/dry cold front that will push through Mon night.

Thursday Night into Friday...Introduced a chance of rain showers for this period as next progressive short wave appears set to translate across the Eastern CONUS. The 22/00Z operational GFS appears to be a dry outlier due to lack of support from the CMC/ECMWF, as well as its NCEP ensemble mean.
