THE BEAUTIFUL ALBEIT DREADFULLY QUIET WEATHER PATTERN LINGERS
THROUGH AT LEAST THE MIDDLE OF NEXT WEEK THANKS TO SURFACE HIGH
PRESSURE REMAINING THE DOMINATE FEATURE OVER THE EASTERN UNITED
STATES. THE MOST "EXCITING" PART OF THE FORECAST WILL BE A DRY AND
CLEAR COLD AIR DAMMING WEDGE BUILDING OVER THE GSP FORECAST AREA
FRIDAY INTO THE WEEKEND, ALLOWING FOR THE RETURN OF NEAR NORMAL TO
JUST BELOW NORMAL HIGHS. PATCHY FROST IS POSSIBLE IN THE NORTH
CAROLINA MOUNTAINS ON BOTH SATURDAY NIGHT AND SUNDAY NIGHT THANKS TO
GREAT RADIATIONAL COOLING CONDITIONS AND COOLER LOWS. SLIGHTLY ABOVE
NORMAL HIGHS RETURN FOR NEXT WEEK.

PREVAIL AT THE TAF SITES THROUGH THE PERIOD. HAVING SAID THAT,
