DISCUSSION
AS OF 228 PM TUESDAY...
KEY MESSAGE 1... UNUSUALLY HOT WEATHER RETURNS STARTING WED, LASTING
THROUGH THE WEEKEND, WITH THE MOST DANGEROUS HEAT ON THU/FRI.
TODAY'S HIGHS, PRIMARILY IN THE 80S EXCEPT FOR A FEW UPPER 70S, WERE
THE COOLEST HIGH TEMPERATURES THAT CAN BE EXPECTED OVER THE NEXT 7
DAYS. THE HEAT WILL BUILD IN ON WEDNESDAY, WITH MOST LOCATIONS
OUTSIDE OF THE TRIAD RISING INTO THE 90S.
THE WARMEST DAYS OF THE WEEK WILL BE THURSDAY THROUGH SATURDAY AS
THE MID-LEVEL RIDGE SHIFTS OVER THE REGION. THIS WILL ALLOW
TEMPERATURES TO RISE GENERALLY INTO THE MID-TO-UPPER 90S ON
THURSDAY, RISING FURTHER INTO THE UPPER 90S ON FRIDAY. THE
PROBABILITY OF MAXIMUM TEMPERATURES GREATER THAN 99 ARE GENERALLY
ABOUT 10-30% OVER THE EASTERN PORTIONS OF THE CWA, WITH A FEW
SPLOTCHES OF 40-50% IN THE SANDHILLS AND THE TRIANGLE. THE
EXPERIMENTAL HEATRISK IS SHOWING THE MAJORITY OF CENTRAL NC UNDER A
MAJOR RISK OF HEAT-RELATED IMPACTS FROM THURSDAY THROUGH SATURDAY,
WITH A FEW LOCATIONS SHOWING AN EXTREME RISK OF HEAT-RELATED IMPACTS
IN THE SANDHILLS. THIS WILL ALSO BE MADE WORSE BY ABOVE NORMAL
TEMPERATURES OVERNIGHT. LOWS LOOK TO REMAIN IN THE LOW-TO-MID 70S
EACH NIGHT, ALLOWING FOR LITTLE RELIEF FROM DAYTIME TEMPERATURES.
HOWEVER, THE CHANCE FOR ISOLATED TO SCATTERED SHOWERS AND
THUNDERSTORMS MAY ALSO PROVIDE SOME RELIEF FROM THE HOT AFTERNOON
TEMPERATURES EACH DAY. THE RIDGE WILL START TO BREAK DOWN SOME,
POTENTIALLY ALLOWING A WEAK COLD FRONT TO APPROACH OR MOVE THROUGH
THE REGION ON SATURDAY OR SUNDAY. THIS SHOULD ALLOW FOR TEMPERATURES
TO COOL DOWN SLIGHTLY TO START NEXT WEEK.
KEY MESSAGE 2... AFTERNOON AND EVENING SHOWER AND THUNDERSTORM
CHANCES WILL CONTINUE EACH DAY THROUGH THE WEEKEND.
THE STATIONARY FRONT THAT HAS BEEN DRAPED FROM NORTHWEST TO
SOUTHEAST JUST TO THE WEST OF THE FORECAST AREA WILL DISSIPATE OVER
THE NEXT FEW HOURS. HOWEVER, BEFORE THAT OCCURS, SOME SHOWERS AND
ISOLATED THUNDERSTORMS COULD MAKE THEIR WAY INTO WESTERN COUNTIES
DURING THE AFTERNOON, WITH CONDITIONS DRYING OUT AFTER SUNSET. AN
UPPER LEVEL SHORTWAVE WILL MOVE ACROSS THE MID-ATLANTIC ON
WEDNESDAY, AND THIS WILL BRING ANOTHER CHANCE FOR SCATTERED SHOWERS
AND THUNDERSTORMS, PRIMARILY WEDNESDAY AFTERNOON.
THE WARM/MOIST AIRMASS WILL REMAIN OVERHEAD FROM MID-WEEK THROUGH
THE WEEKEND. A DAILY PATTERN OF ISOLATED TO SCATTERED DIURNALLY
INDUCED SHOWERS AND EMBEDDED THUNDERSTORMS LOOKS TO RETURN TO THE
REGION THURSDAY THROUGH THE WEEKEND. THE TYPICAL SUMMER-LIKE PATTERN
IS CURRENTLY LOW PREDICTABILITY IN EXACTLY WHERE SHOWERS MAY DEVELOP
EACH AFTERNOON. HOWEVER, RAINFALL AMOUNTS LOOK TO BE RELATIVELY
LIGHT, WITH THE 50TH PERCENTILE OF THE LREF SHOWING LESS THAN 0.1
INCH OF RAIN THURSDAY AND FRIDAY. THIS WEEKEND, FORCING WILL
INCREASE SLIGHTLY AS A FRONT LOOKS TO FALL APART AS IT APPROACHES
THE AREA WHICH MAY ALLOW FOR SLIGHTLY HIGHER RAINFALL TOTALS AND
POTENTIALLY MORE ORGANIZED STORMS. THE LREF IS SHOWING UP TO 0.15
INCH OF RAIN ON SATURDAY AND AN ADDITIONAL 0.10 INCH ON SUNDAY. THE
FRONTAL BOUNDARY LOOKS TO WAVER OVER THE REGION INTO NEXT WEEK,
ALLOWING FOR CONTINUED RAIN CHANCES EARLY WEEK.
AVIATION /06Z WEDNESDAY THROUGH SUNDAY/
AS OF 155 AM WEDNESDAY...
WITH THE EXCEPTION OF A FEW HOURS THIS MORNING AND PERHAPS WITH
SCATTERED CONVECTION LATER TODAY, VFR CONDITIONS SHOULD LARGELY
PREVAIL, ALTHOUGH CONSIDERABLE MULTI-LEVEL CLOUDINESS (RESULTING
FROM THE DEBRIS OF UPSTREAM CONVECTION) WILL PASS OVER THE AREA
TODAY. CURRENT CONDITIONS ARE VFR AT MOST CENTRAL NC OBSERVATION
SITES, BUT AREAS OF MVFR CIGS ALREADY DEVELOPING OVER THE PIEDMONT
AND W SANDHILLS ARE EXPECTED TO EXPAND THROUGH DAYBREAK, RESULTING
IN A PROBABLE PERIOD OF MVFR CIGS AT ALL CENTRAL NC TERMINALS
BETWEEN 09Z AND 14Z THIS MORNING. VSBYS MAY ALSO BRIEFLY GO MVFR 10Z-
13Z AT INT/GSO. AFTER 14Z, VFR CONDITIONS SHOULD THEN DOMINATE
THROUGH AT LEAST MID AFTERNOON. SCATTERED SHOWERS AND STORMS ARE
EXPECTED TO MOVE INTO THE N PIEDMONT AFTER 19Z, PERHAPS AFFECTING
INT/GSO 18Z-23Z AND RDU 19Z-01Z WITH A CHANCE FOR BRIEF DOWNPOURS
AND ENHANCED WIND GUSTS. THERE WILL BE A LOWER CHANCE AT RWI/FAY,
WHERE CONVECTION WON'T BE MENTIONED FOR NOW. AFTER 01Z, EXPECT
LARGELY MID LEVEL CLOUDS INTO THE OVERNIGHT HOURS. SURFACE WINDS
WILL BE FROM THE SSW OR SW, UNDER 10 KTS UNTIL 13Z AND AFTER 02Z
TONIGHT, BUT OTHERWISE AROUND 9-14 KTS WITH SPORADIC GUSTS TO 15-20
KTS.
LOOKING BEYOND 06Z THU, VFR CONDITIONS ARE EXPECTED FOR MUCH OF THE
TIME THROUGH THE WEEKEND, HOWEVER DAYTIME SCATTERED SHOWERS/STORMS
WILL REMAIN POSSIBLE AREAWIDE EACH DAY, WHICH MAY CAUSE BRIEF SUB-
VFR CIGS/VSBYS IN DOWNPOURS AND BRIEF GUSTY WINDS. AND AREAS OF SUB-
VFR CONDITIONS IN STRATUS AND FOG ARE POSSIBLE EARLY EACH MORNING.
