DISCUSSION
AS OF 250 PM MONDAY...
KEY MESSAGE 1... EXCEPT FOR TUESDAY, HIGHS ARE EXPECTED TO BE IN THE
90S EVERYWHERE FOR THE NEXT WEEK, BRINGING DANGER TO THOSE WHO LACK
ADEQUATE COOLING.
TONIGHT WILL BE THE COOLEST NIGHT OUT OF THE NEXT SEVEN, WITH LOWS
RANGING FROM THE MID 50S IN THE NORTHEAST TO 70 IN THE SOUTHWEST.
SIMILARLY, TUESDAY WILL BE THE COOLEST DAY OUT OF THE NEXT SEVEN.
THE TRIAD WILL BE ON THE COOL SIDE OF THE FRONT, SO HIGHS WILL BE IN
THE MID 80S, WHILE LOCATIONS TO THE EAST SHOULD GENERALLY BE AROUND
90 DEGREES.
AFTER THE SURFACE HIGH PRESSURE MOVES OFF THE MID-ATLANTIC COAST ON
TUESDAY, WARM AND MOIST SOUTHERLY FLOW WILL RETURN TO THE REGION AS
RIDGING WILL START TO BUILD TO THE WEST. THIS WILL ALLOW
TEMPERATURES TO RISE GENERALLY INTO THE LOW-TO-MID 90S ON WEDNESDAY
AND INCREASE FURTHER IN TO THE MID-TO-UPPER 90S ON THURSDAY AND THE
UPPER 90S ON FRIDAY. THE PROBABILITY OF HIGH TEMPERATURES REACHING
OR EXCEEDING 100 DEGREES ON FRIDAY IS BETWEEN 10-30% FOR THE
MAJORITY OF THE US-1 CORRIDOR AND EAST. THE EXPERIMENTAL HEATRISK IS
SHOWING THE MAJORITY OF CENTRAL NC UNDER A MODERATE TO MAJOR RISK OF
HEAT-RELATED IMPACTS FROM WEDNESDAY THROUGH AT LEAST SUNDAY, WITH A
FEW LOCATIONS SHOWING AN EXTREME RISK OF HEAT-RELATED IMPACTS ON
FRIDAY AND SATURDAY. 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.
KEY MESSAGE 2... DIURNALLY-DRIVEN THUNDERSTORMS WILL BE POSSIBLE
THROUGHOUT THE NEXT SEVEN DAYS, WITH THE LOWEST CHANCES ON THURSDAY
AND THE GREATEST CHANCES ON SATURDAY.
A BACK DOOR COLD FRONT IS CURRENTLY ORIENTED FROM NORTHWEST TO
SOUTHEAST ACROSS THE FORECAST AREA. WHILE THE FRONT HAS MOVED ACROSS
THE AREA TODAY, IT WILL TAKE ITS TIME DRIFTING TO THE SOUTHWEST
THROUGH THE REST OF THE AFTERNOON AND OVERNIGHT. THE FRONT SHOULD
SERVE AS A FOCUS FOR SHOWERS AND THUNDERSTORMS TO DEVELOP, WITH THE
PRECIPITATION EXPECTED SOUTH AND WEST OF THE TRIANGLE. WHILE RAP
SBCAPE WILL RANGE FROM 1000 TO 3000 J/KG, A LACK OF WIND SHEAR WILL
LIMIT THE POTENTIAL FOR SEVERE THUNDERSTORMS. HOWEVER, DCAPE VALUES
APPROACHING 1000 J/KG COULD ALLOW FROM STRONG WINDS. BY SUNSET, A
SLIGHT CHANCE OF SHOWERS WILL CONTINUE WEST OF I-74, BUT CONDITIONS
SHOULD DRY OUT BY MIDNIGHT. THE FRONT WILL MOVE LITTLE TUESDAY AND
TUESDAY NIGHT, AND RAINFALL WILL GENERALLY REMAIN WEST OF THE
TRIANGLE, WITH SHOWERS/STORMS LIKELY IN THE TRIAD.
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 WEDNESDAY 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 EACH DAY THROUGH 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 0.25 INCH OF RAIN ON SATURDAY AND AN ADDITIONAL 0.1 INCH ON
SUNDAY.
AVIATION /06Z TUESDAY THROUGH SATURDAY/
AS OF 1255 AM TUESDAY...
ISOLATED SHOWERS PERSIST NEAR THE TRIAD TERMINALS CURRENTLY, BUT
THESE SHOULD CONTINUE TO DIMINISH OVER THE NEXT COUPLE OF HOURS.
WESTERN AND SOUTHERN SECTIONS OF CENTRAL NC, INCLUDING INT/GSO/FAY
AND AREAS THAT SAW RAINFALL YESTERDAY, ARE LIKELY TO SEE DEVELOPMENT
OF MVFR CIGS MAINLY AFTER 08Z AND LASTING THROUGH MUCH OF THE
MORNING. AND AT INT AND PERHAPS GSO, A PERIOD OF IFR CIGS ARE
EXPECTED STARTING TOWARD SUNRISE AND LASTING THROUGH AT LEAST MID
MORNING. RDU HAS A GOOD CHANCE OF SEEING A SHORT PERIOD OF MVFR CIGS
BETWEEN 12Z AND 15Z, BUT OVERALL, RDU/RWI ARE EXPECTED TO STAY VFR
THROUGH THIS EVENING, ALTHOUGH PERIODS OF MID AND HIGH LEVEL CIGS
WILL CONTINUE AREAWIDE. REGARDING PRECIP, SCATTERED SHOWERS AND A
FEW STORMS ARE POSSIBLE NEAR INT/GSO LATE TODAY, MAINLY FROM 20Z
THROUGH 04Z, WHILE OTHER TERMINALS SHOULD STAY MOSTLY DRY. SURFACE
WINDS WILL BE 10 KTS OR LESS FROM THE ESE OR E THROUGH 13Z, THEN
VEER TO BE FROM THE SE AND SSE BY LATE MORNING AND FROM THE SW TO
WSW THIS AFTERNOON AT 10-15 KTS, THEN UNDER 10 KTS AFTER SUNSET.
LOOKING BEYOND 06Z WED, THERE IS A GOOD CHANCE OF SUB-VFR CIGS
AREAWIDE LATE TONIGHT THROUGH MID WED MORNING, WITH THE HIGHEST
CONFIDENCE AT INT/GSO. OTHERWISE, VFR CONDITIONS ARE EXPECTED TO
DOMINATE INTO THE WEEKEND, ALTHOUGH DAYTIME ISOLATED TO SCATTERED
SHOWERS/STORMS WILL REMAIN POSSIBLE AREAWIDE EACH DAY, WHICH MAY
CAUSE BRIEF SUB-VFR VSBYS IN DOWNPOURS AND BRIEF GUSTY WINDS.
