DISCUSSION
KEY MESSAGE 1...HIGH PRESSURE BUILDS IN TONIGHT THROUGH
SATURDAY BRINGING CLEARING SKIES WITH COOLER AND LESS HUMID
CONDITIONS.
A COLD FRONT STILL LOCATED NEAR THE COAST WILL MOVE SOUTH OF THE
AREA BEFORE DAWN. BEHIND THE COLD FRONT, IT LOOKS DRIER INTO AT
LEAST TOMORROW. A HIGH PRESSURE SYSTEM BUILDS IN FOR SATURDAY
KEEPING THE AREA DRY. AN UPPER-LEVEL DISTURBANCE MOVING THROUGH
THE REGION ON SUNDAY HAS THE POTENTIAL TO RESULT IN SOME SHOWERS
AND THUNDERSTORMS, PARTICULARLY DURING THE AFTERNOON AND
EVENING HOURS.
KEY MESSAGE 2...INCREASING HEAT AND HUMIDITY RETURN NEXT WEEK
WITH UNSETTLED WEATHER.
BROAD UPPER LEVEL RIDGING RETURNS TO THE EASTERN US EARLY NEXT WEEK,
BRINGING IN SURFACE HIGH PRESSURE ACROSS THE EASTERN US.
AFTERNOON HIGHS WILL CREEP BACK INTO THE UPPER 80S TO LOW 90S, ABOUT
5 DEGREES ABOVE AVERAGE FOR EARLY SEPTEMBER. DEW POINTS WILL ALSO
CREEP BACK INTO THE LOW 70S. ONE OTHER ASPECT TO WATCH WITH THIS
RIDGING PATTERN IS THE POTENTIAL FOR THUNDERSTORMS TO ROTATE
AROUND THE PERIPHERY OF THE RIDGE AND THE POSITION OF A WARM
FRONT NEXT WEEK. THE EXACT LOCATION, TIMING, AND INTENSITY OF
THE THUNDERSTORMS REMAINS A BIT UNCERTAIN AT THIS RANGE.
CURRENTLY, THE MAIN DAYS TO MONITOR ARE TUESDAY AND WEDNESDAY
REGARDING HEAVY RAIN AND SEVERE WEATHER POTENTIAL.
