DISCUSSION
KEY MESSAGE 1...DRIER AND COOLER TODAY.
THE COLD FRONT THAT BROUGHT WIDESPREAD RAIN TO THE AREA YESTERDAY
HAS NOW STALLED ACROSS THE CAROLINAS, AND LOOKS TO REMAIN OVER THAT
REGION THROUGH THE WEEKEND. DRIER AIR IS WORKING ITS WAY INTO THE
LOCAL AREA, AS DEWPOINTS HAVE BEEN SLOWLY FALLING INTO THE LOW 60S
TO UPPER 50S IN SOME LOCATIONS. EAST TO NORTHEASTERLY FLOW IS
BRINGING IN SOME MOISTURE FROM THE COASTAL MID ATLANTIC, SO IT WILL
STAY PARTLY TO MOSTLY CLOUDY FOR MOST OF THE DAY, UNTIL SOME MORE
BREAKS IN THE CLOUD COVER CAN BRING SOME SUN. HOWEVER, NOT ENOUGH
SUN TO HELP TEMPERATURES SIGNIFICANTLY INCREASE. HIGHS THIS
AFTERNOON WILL BE IN THE 60S TO LOW 70S, WHICH IS ABOUT 5 TO 10
DEGREES BELOW NORMAL IN THE MOUNTAINS, AND 10 TO 20 DEGREES BELOW
NORMAL IN THE PIEDMONT.
MOST OF THE SHOWER ACTIVITY HAS SHIFTED FARTHER SOUTH INTO
CENTRAL NC, AND SO NOT CONFIDENT IN REDEVELOPMENT BY THIS
AFTERNOON, BUT CANNOT RULE OUT A FEW STRAY SHOWERS LATER TODAY
OVER THE MOUNTAINS AND ALONG THE VA/NC BORDER.
KEY MESSAGE 2... COOLER THAN NORMAL TEMPERATURES CONTINUE THROUGH
THE WEEKEND, WITH SHOWER AND STORM CHANCES RETURNING TO THE
AREA TOMORROW INTO EARLY NEXT WEEK.
A SURFACE HIGH OVER THE NORTHERN MID ATLANTIC AND NEW ENGLAND WILL
KEEP NORTHEAST TO EASTERLY LOW LEVEL WINDS ADVECTING SOME
COOLER AIR INTO THE AREA, AND SO EXPECTING THESE BELOW NORMAL
TEMPERATURES THROUGH THE WEEKEND. TEMPERATURES WILL START TO
SLOWLY INCREASE AFTER SUNDAY, AS A MORE TYPICAL SUMMERTIME
PATTERN RESUMES OVER THE US, WITH BROAD UPPER TROUGHING
PERSISTING IN THE EAST AND A 500MB RIDGE BUILDING ACROSS THE
MOUNTAIN WEST. SOME MOISTURE WILL MOVE BACK INTO THE AREA FROM
VIA RETURN FLOW AROUND THE HIGH AND POOLING ALONG THE FRONT
STALLED ACROSS THE SOUTHEASTERN US, WHILE A COUPLE SHORTWAVES
DROP INTO THE AREA IN THE BROAD NORTHWESTERLY FLOW ALOFT. THIS
WILL COMBINE TO BRING SHOWER AND THUNDERSTORM CHANCES BACK INTO
THE FORECAST TOMORROW, AND LINGERING THROUGH THE WEEKEND. AT
THIS TIME, THE PROBABILITY FOR ANY SEVERE THUNDERSTORMS IS LOW,
UNTIL EARLY NEXT WEEK, WHEN A STRONGER SHORTWAVE AND SURFACE
COLD FRONT LOOK TO ARRIVE FROM THE MIDWEST. CONFIDENCE IN TIMING
IS LOW, GIVEN DIFFERENCES AMONG DETERMINISTIC GUIDANCE, AND THE
GEFS ML SEVERE PROBABILITY HAS LOW PROBABILITY, BETWEEN 15% AND
30%, SUNDAY THROUGH TUESDAY, SO DIFFICULT TO PINPOINT THE DAY
WITH THE HIGHEST SEVERE POTENTIAL AT THIS TIME.
AVIATION /00Z FRIDAY THROUGH TUESDAY/
CEILINGS HAVE BEEN HOVERING BETWEEN LOW END VFR AND MVFR, WITH A FEW
SPOTS IN HIGHER ELEVATIONS WHERE CEILINGS ARE BELOW 1KFT. GIVEN
THE PROXIMITY OF THE FRONT AND MOISTURE ALONG IT, AND SOME
COOLING OVERNIGHT, CEILINGS WILL ONCE AGAIN LOWER TO MVFR TO IFR
RANGE, POSSIBLY BELOW THAT, AFTER 06Z FRIDAY THROUGH MOST OF
THE MORNING HOURS. CANNOT RULE OUT A FEW ISOLATED SHOWERS DURING
THE OVERNIGHT AND EARLY MORNING. CLOUDS WILL PERSIST THROUGH
FRIDAY, WITH BKN/OVC TO CONTINUE, ALONG WITH LOW END VFR AND
SOME MVFR INTO THE AFTERNOON.
WINDS WILL BE MOSTLY NORTHEAST TO EASTERLY THROUGH TODAY, AND 10
KNOTS OR LESS, WITH THE OCCASIONAL GUST BETWEEN 15 AND 20 KNOTS IN
THE AFTERNOON.
EXTENDED AVIATION OUTLOOK...
CHANCES FOR AFTERNOON SHOWERS AND POSSIBLE STORMS INCREASE
THROUGH THE WEEKEND, BUT COVERAGE WILL BE ISOLATED TO SCATTERED.
OUTSIDE OF SHOWERS/STORMS, AND OVERNIGHT/MORNING FOG,
CONDITIONS SHOULD BE GENERALLY VFR.
