DISCUSSION
AS OF 300 AM THURSDAY...
KEY MESSAGE 1... MUCH ABOVE NORMAL TEMPERATURES THURSDAY AND FRIDAY
AFTERNOONS, WITH A SLIGHT DECREASE IN HEAT OVER THE WEEKEND.
A LACK OF CLOUD COVER ALLOWED FOR TEMPERATURES TO RISE RAPIDLY
TODAY, AND THE DEVELOPMENT OF SOME DIURNAL CUMULUS HAS ONLY SLOWED
THE RISE THIS AFTERNOON. ISOLATED LOCATIONS ARE LIKELY TO REACH 100
DEGREES THIS AFTERNOON, AND A HEAT ADVISORY REMAINS IN EFFECT FOR
MUCH OF THE FORECAST AREA THROUGH 8PM TONIGHT. NO LOCATION IS
EXPECTED TO FALL BELOW 70 TONIGHT, WITH RALEIGH AND FAYETTEVILLE
LIKELY TO ONLY DROP INTO THE MID 70S. HIGH TEMPERATURES WILL CLIMB
ANOTHER FEW DEGREES TOMORROW, AND CONSIDERING DEWPOINTS SHOULD BE
SIMILAR, UPPER 60S TO 70, THAT WILL BRING NEARLY ALL LOCATIONS TO
THE MAJOR CATEGORY (LEVEL 3 OF 4) OF EXPERIMENTAL HEAT RISK. THAT
INDICATES THAT SIGNIFICANT ADVERSE HEALTH IMPACTS ARE POSSIBLE FOR
ALL POPULATIONS WITHOUT ADEQUATE COOLING OR HYDRATION, AND HEAT
ILLNESSES MAY DEVELOP SUDDENLY FOR THOSE WORKING OR EXERCISING
OUTDOORS DURING THE HOTTEST PART OF THE DAY. WILL ISSUE ANOTHER HEAT
ADVISORY FOR FRIDAY, THIS TIME FOR THE ENTIRE FORECAST AREA. HIGH
TEMPERATURES SHOULD DROP A COUPLE DEGREES FOR THE WEEKEND.
KEY MESSAGE 2... POTENTIAL FOR STRONG TO SEVERE THUNDERSTORMS BOTH
THURSDAY AND FRIDAY AFTERNOONS, WITH GREATER COVERAGE TO THE NORTH.
THE PRIMARY THREAT OF SEVERE WEATHER TODAY WILL REMAIN TO THE NORTH
ACROSS VIRGINIA, BUT A MARGINAL (LEVEL 1 OF 5) RISK OF SEVERE
THUNDERSTORMS CURRENTLY EXTENDS ONE TO TWO COUNTIES INTO NORTH
CAROLINA NEAR THE VIRGINIA BORDER. DIURNAL CUMULUS HAS FORMED ACROSS
THE REGION, AND MLCAPE VALUES ARE BETWEEN 1000 AND 2000 J/KG. A LACK
OF WIND SHEAR OR A BOUNDARY WILL PREVENT MUCH IN THE WAY OF
ORGANIZED STORMS, BUT DCAPE VALUES OVER 1000 J/KG WILL BRING THE
POTENTIAL FOR STRONG WIND GUSTS IN ANY STORMS THAT DO DEVELOP.
OVERALL COVERAGE OF THUNDERSTORMS SHOULD REMAIN ISOLATED.
AS FOR FRIDAY, THE MCS CURRENTLY PRODUCING SEVERE WEATHER ACROSS THE
PLAINS WILL MOVE SOUTHEAST OVER THE NEXT 24-36 HOURS, SERVING AS THE
FOCUS FOR ORGANIZED THUNDERSTORMS FRIDAY AFTERNOON. THE THURSDAY
AFTERNOON UPDATE TO THE FRIDAY SEVERE POTENTIAL SLIGHTLY EXPANDED
BOTH THE SLIGHT RISK AND MARGINAL RISK FOR SEVERE WEATHER AN
ADDITIONAL 1-2 COUNTIES FARTHER SOUTH. THE CURRENT TIMING FOR THE
MCS DOES NOT BRING IT INTO THE TRIAD UNTIL AT LEAST MID-AFTERNOON,
WHICH NOT ONLY MEANS THAT THE SEVERE POTENTIAL WOULD BE MORE IN THE
LATE AFTERNOON AND EVENING HOURS, IT WOULD ALSO ALLOW FOR A LONGER
PERIOD OF HEATING DURING THE DAY. MLCAPE VALUES WILL BE BETWEEN 1000
AND 2000 J/KG, AND WHILE SHEAR VALUES WON'T BE MUCH HIGHER FRIDAY
THAN THEY ARE TODAY, THE EXISTING MCS WILL BE ABLE TO HELP ORGANIZE
STORM DEVELOPMENT. NEARLY ALL PRECIPITATION SHOULD COME TO AN END BY
MIDNIGHT. FRIDAY'S PRIMARY SEVERE WEATHER THREAT WILL BE DAMAGING
WIND. FINALLY, IN ADDITION TO THE SEVERE WEATHER THREAT, THERE IS A
MARGINAL THREAT FOR EXCESSIVE RAINFALL TOMORROW. DESPITE THE DROUGHT
CONDITIONS, IF RAIN RATES ARE HEAVY ENOUGH FOR A LONG AMOUNT OF
TIME, THERE WILL STILL BE THE POTENTIAL FOR FLOODING.
KEY MESSAGE 3... AFTERNOON AND EVENING THUNDERSTORM CHANCES WILL
CONTINUE EACH DAY SATURDAY INTO THE MIDDLE OF NEXT WEEK.
A WEAKENING COLD FRONT WILL MOVE ACROSS MUCH OF OUR REGION LATE
FRIDAY NIGHT AND SATURDAY, STALLING OVER SOUTHEASTERN NC OVER THE
WEEKEND. THE NEXT COLD FRONT WILL APPROACH ON SUNDAY AND MOVE INTO
THE AREA ON MONDAY, WHERE IT MAY LINGER INTO MID-WEEK. DIURNAL,
PULSE-TYPE CONVECTION IS EXPECTED DAILY INTO NEXT WEEK. FOR NOW, THE
DAYS WITH THE HIGHEST PROBABILITY OF SHOWERS/STORMS APPEARS TO BE
SUNDAY AND TUESDAY. RAINFALL AMOUNTS REMAIN A BIT UNCERTAIN AT THIS
TIME.
AVIATION /06Z FRIDAY THROUGH TUESDAY/
AS OF 100 AM FRIDAY...
VFR CONDITIONS ARE LIKELY TO DOMINATE ACROSS CENTRAL NC FOR THE NEXT
24 HOURS, HOWEVER SCATTERED SHOWERS AND STORMS LATER TODAY MAY BRING
A PERIOD OF SUB-VFR CONDITIONS IN BRIEF HEAVY DOWNPOURS, GUSTY
WINDS, AND OF COURSE LIGHTNING. FAIR SKIES WITH AREAS OF MID LEVEL
CLOUDS ARE EXPECTED THROUGH THE MORNING, THEN WITH ANOTHER DAY OF A
VERY HOT AND HUMID AIR MASS IN PLACE, WE'LL SEE DEVELOPMENT OF
SCATTERED SHOWERS AND STORMS STARTING TO OUR SOUTHEAST (ALONG AN
INLAND-MOVING SEA BREEZE) AND TO OUR NORTHWEST (OVER SOUTHERN VA AND
NW NC) MAINLY AFTER 20Z. AS THESE SHOWERS AND STORMS SPREAD INTO THE
AREA, THE RISK FOR ADVERSE AVIATION CONDITIONS WILL BE GREATEST 21Z-
02Z AT INT/GSO AND 23Z-05Z AT RDU/RWI/FAY. ANY SHOWERS AND STORMS
SHOULD WEAKEN AND FALL APART AFTER 05Z, LEAVING BEHIND MOSTLY VFR
SCT-BKN DEBRIS CLOUDINESS INTO THE OVERNIGHT HOURS. SURFACE WINDS
WILL BE MAINLY FROM THE SW AND W INTO THE EVENING, BEFORE SHIFTING
TO BE FROM THE NW AND N BEHIND THE STORMS LATER TONIGHT, ALL AT
SPEEDS AROUND 8-15 KTS BUT LOWER THROUGH DAYBREAK AND LATE TONIGHT.
LOOKING BEYOND 06Z SAT, VFR CONDITIONS ARE EXPECTED INTO EARLY SAT
AFTERNOON, ALTHOUGH ANOTHER ROUND OF SCATTERED SHOWERS AND STORMS IS
EXPECTED SAT AFTERNOON WITH HIGHEST CHANCES OVER THE SE AFFECTING
FAY AND LOWER CHANCES ELSEWHERE. SCATTERED TO NUMEROUS SHOWERS AND
STORMS WILL REMAIN POSSIBLE SAT NIGHT THROUGH TUE, WITH THE HIGHEST
COVERAGE EXPECTED TO BE SUN/SUN NIGHT AND AGAIN MON NIGHT-TUE, AND
ANY OF THESE COULD BRING A PERIOD OF ADVERSE AVIATION WEATHER.
