KEY MESSAGES
1) RISK OF DANGEROUS HEAT LATER THIS WEEK.

STORMS LATE WEEK INTO THE WEEKEND.
DISCUSSION
KEY MESSAGE 1...GUIDANCE CONTINUES HIGH WITH LOW LEVEL
THICKNESSES LATER THIS WEEK, WITH THE WARMEST TEMPERATURES
EXPECTED THURSDAY AND ESPECIALLY FRIDAY. WHILE TEMPERATURES MAY
FLIRT WITH RECORDS AT BEST, FORECAST AIDS AND ENSEMBLE GUIDANCE
SUGGEST MULTIPLE DAYS OF WELL ABOVE NORMAL TEMPERATURES. THIS
COMBINED WITH INCREASING HUMIDITY IS FORECAST TO SUPPORT
WIDESPREAD "FEELS LIKE" TEMPERATURES OF 100-105 DEGREES, WITH
THE BEST CHANCE OF REACHING RECORDS AND/OR HEAT INDICES ABOVE
105 ON FRIDAY. ADDITIONALLY, THE NWS' EXPERIMENTAL HEAT RISK
GUIDANCE SHOWS A MODERATE TO MAJOR HEAT RISK FOR MUCH OF ENC
FROM FRIDAY INTO THE WEEKEND. THE ONE CAVEAT (DISCUSSED IN MORE
DETAIL IN KEY MESSAGE 2) IS THE POTENTIAL FOR AFTERNOON
SHOWERS/STORMS LATE IN THE WEEK AS THIS COULD PROVIDE RELIEF
FROM THE HEAT FOR SOME AREAS EACH DAY.
KEY MESSAGE 2...INCREASING MOISTURE AND INSTABILITY BENEATH
WEAKENING RIDGING ALOFT IS EXPECTED TO SUPPORT A PATTERN THAT IS
MORE CONDUCIVE TO A DAILY RISK OF CONVECTION. INITIALLY THIS
MAY BE MOSTLY SEEN AS A MORE ACTIVE SEABREEZE. HOWEVER, BY THE
WEEKEND THERE MAY BE SOME ADDED LARGE-SCALE FORCING FROM VARIOUS
UPPER LEVEL IMPULSES FORECAST TO MOVE THROUGH, OR GLANCE, THE
REGION. WHILE THE STRONGEST SHEAR LOOKS TO BE REMOVED FROM THE
AREA, MODERATE TO STRONG INSTABILITY MAY SUPPORT A DAILY RISK OF
MARGINALLY SEVERE, PULSE CONVECTION (FAIRLY TYPICAL FOR THIS
TIME OF YEAR).
AVIATION /18Z MONDAY THROUGH SATURDAY/
BACKDOOR COLD FRONT MOVING THROUGH WILL LEAD TO NERLY TO ERLY
WINDS, WITH GUSTS APPROACHING 20 KT THIS AFTERNOON. A BRIEF
PERIOD OF SCT LOW CLOUDS MAY FOLLOW BEHIND THE FRONT, ESP
INTERIOR AREAS. HOWEVER, THE RISK OF WIDESPREAD BKN SUB-VFR
CIGS APPEARS LOW.
OUTLOOK (TUESDAY THROUGH SATURDAY): HIGH PRESSURE BUILDS INTO
TUESDAY WITH GENERALLY LOW-IMPACT AVIATION CONDITIONS EXPECTED.
SRLY TO SWRLY FLOW RETURNS WITH INC MOISTURE AND INSTABILITY
WITHIN THIS FLOW SLOWLY BUT SURELY. BY THU THERE WILL BE SMALL
CHANCES (20-30%) OF AFTERNOON SHOWERS/STORMS AT ANY GIVEN
LOCATION, ESP INLAND AREAS ALONG THE SEABREEZE. THESE MAY BRING
BRIEF GUSTY WINDS, AND TEMPO REDUCTION IN VSBY IN HEAVIER
SHOWERS.
MARINE
A BACKDOOR COLD FRONT HAS PASSED THROUGH WITH OCCASIONAL GUSTS
OF 20-25KT THROUGH EARLY EVENING. WATERS FAVORED IN NORTHEAST
FLOW (PAMLICO SOUND, MOUTH OF THE NEUSE RIVER) APPEAR TO HAVE
THE HIGHEST CHANCE TO REACH 25KT. IT LOOKS A BIT MARGINAL AND
BRIEF WITH THE WIND GUSTS OF AOA 25KT, SO WILL HOLD OFF ON SCA
ISSUANCE ATTM. SEAS OF 4-5FT WILL BE COMMON, WITH SOME 6-7FT
WAVES POSSIBLE FOR THE OFFSHORE WATERS WITH THE FLOW AGAINST THE
GULF STREAM. WINDS WILL DIMINISH TO 10-15 KT LATER TONIGHT, AND
VEER SRLY TO SWRLY ON TUE WITH SPEEDS REMAINING IN THE 10-15 KT
RANGE.
OUTLOOK (TUE NIGHT THROUGH SAT): HIGH PRESSURE CONTINUES TO
DOMINATE. FROM MID TO LATE WEEK, A STRENGTHENING SWRLY FLOW IS
FORECAST TO DEVELOP DUE TO THE STRENGTHENING THERMAL GRADIENT.
A DAILY RISK OF 25KT WINDS APPEARS LIKELY DURING THIS TIME,
ESPECIALLY WEDNESDAY AND THURSDAY AFTERNOON AND EVENINGS WHEN
THE THERMAL GRADIENT IS EXPECTED TO BE THE STRONGEST.
