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 /18Z THURSDAY THROUGH TUESDAY/
AS OF 130 PM THURSDAY...
TAF PERIOD: VFR CONDITIONS ARE EXPECTED ACROSS CENTRAL NORTH
CAROLINA TERMINALS OVER THE LAST 24 HOURS; HOWEVER, ISOLATED SHOWERS
AND THUNDERSTORMS ARE EXPECTED THROUGH 03Z. ALL OF THE ACTIVITY IS
EXPECTED TO REMAIN NORTH OF FAY. INT, GSO, RDU, AND RWI WILL ALL
HAVE THE POTENTIAL FOR THUNDERSTORMS, HOWEVER CONFIDENCE REMAINS TOO
LOW IN ANY PARTICULAR SITE HAVING A THUNDERSTORM TO ADD
PRECIPITATION TO THE FORECAST. DIURNAL CUMULUS WILL CLEAR WITH
SUNSET, AND WHILE NO WIDESPREAD RESTRICTIONS ARE EXPECTED TONIGHT,
ANY SITE THAT RECEIVES PRECIPITATION THIS AFTERNOON COULD HAVE
RESTRICTIONS OVERNIGHT. WIND WILL BE OUT OF THE SOUTHWEST BETWEEN 5-
10 KT.
OUTLOOK: DIURNALLY DRIVEN SHOWERS AND THUNDERSTORMS ARE EXPECTED
LATE FRIDAY AFTERNOON INTO FRIDAY EVENING. AFTER THAT, DIURNALLY
DRIVEN SHOWERS/STORMS ARE EXPECTED EACH DAY, WITH GREATER COVERAGE
ON SUNDAY AND TUESDAY. LOCAL RESTRICTIONS WILL BE POSSIBLE AT ANY
TERMINAL WITH THE PRECIPITATION, AS WELL AS LATER THAT NIGHT AROUND
SUNRISE.
