-POTENTIAL FOR HAZARDOUS HEAT FROM THURSDAY THROUGH MONDAY
JET STREAM AND A STREAM OF SHORTWAVES ARE PINNED WELL TO OUR NORTH
WITH RIDGING DOMINATING THE SYNOPTIC FLOW OVER THE SE THROUGH THE
LONG TERM. THIS BRINGS A TYPICAL SUMMERTIME PATTERN TO THE CWA
THROUGH THE LONG TERM, WITH DAILY PULSE T-STORMS FUELED BY HIGH
INSTABILITY, LOW SHEAR, AND HIGH PWATS WITH SLOW STORM MOTIONS
BRINGING FREQUENT LIGHTNING, BRIEF PERIODS OF HEAVY RAIN, AND STRONG
(SUB-SEVERE) WIND GUSTS. THURSDAY AND FRIDAY DRIER MID AND UPPER
LEVELS KEEP RAIN CHANCES A BIT BELOW CLIMO, BUT THEN AN INCREASE IN
MOISTURE FOR THE WEEKEND INTO EARLY NEXT WEEK BRINGS RAIN CHANCES TO
AT OR ABOVE CLIMO. WITH RIDGING BUILT OVER THE REGION, THURSDAY
THROUGH SATURDAY HIGH TEMPS IN THE MID 90S PAIRED WITH TDS IN THE
MID TO UPPER 70S BRINGS APPARENT TEMPERATURES BETWEEN 100-110F. HEAT

CLOUDS AND SSW BREEZE SHOULD LIMIT FOG THREAT THIS MORNING,

CONDITIONS TO THE TERMINALS.

AS OF 130 AM WED...THERE WILL BE A CHANCE FOR SOME DIURNAL
SHOWERS AND THUNDERSTORMS THROUGH SUNDAY. THOUGH THE LOWEST
CHANCES TO SEE SHOWERS OR THUNDERSTORMS WILL BE ON THURSDAY AND
FRIDAY AS A RELATIVELY DRIER AIRMASS OVERSPREADS ENC. EITHER
WAY, A LOW END THREAT AT SUB-VFR CONDITIONS EACH AFTERNOON AND
EARLY EVENING IS EXPECTED ACROSS ENC INTO THIS WEEKEND. IF IT
DOES RAIN, THEN THERE WILL ALSO BE A FOG AND LOW STRATUS THREAT

MARINE
SHORT TERM /THROUGH TONIGHT/...
AS OF 215 AM WED...LATEST OBS SHOW SW WINDS 10-15 KT WITH SEAS
2-3 FT. TYPICAL SUMMERTIME PATTERN WILL CONTINUE THROUGH
TONIGHT, WITH SSW WINDS INCREASING TO 10-20 KT THIS AFTERNOON
AND EARLY EVENING AS THERMAL GRADIENT STRENGTHENS. COULD SEE A
FEW GUSTS APPROACH 25 KT BY LATE AFTERNOON/EARLY EVENING OVER
THE EASTERN PAMLICO SOUND, ROANOKE/CROATAN SOUNDS BUT STILL
LOOKS TOO MARGINAL FOR SCA. SEAS WILL BUILD TO 2-4 FT THIS
EVENING. SCATTERED SHOWERS AND A FEW STORMS WILL LIKELY IMPACT
THE COASTAL WATERS AND SOUNDS THROUGH MID MORNING, TRANSITIONING
INLAND THIS AFTERNOON.
LONG TERM /THURSDAY THROUGH SUNDAY/...
AS OF 130 AM WED...CONDITIONS CONTINUE DETERIORATING THURS AS THE
THERMAL TROUGH STRENGTHENS FURTHER. WINDS INCREASE TO 15-25 KTS WITH
HIGHER GUSTS ACROSS ALL WATERS. THIS WILL BRING A THREAT FOR SCA
CONDITIONS, MAINLY ACROSS THE PAMLICO/CROATAN/ROANOKE SOUNDS AND THE
CENTRAL COASTAL WATERS WHICH WILL HAVE THE MOST FAVORABLE
ORIENTATION FOR SCA`S GIVEN THE WIND DIRECTION. AS WE GET INTO THE
WEEKEND WINDS DO EASE SLIGHTLY AS RIDGING TO OUR EAST WEAKENS,
ALLOWING SW`RLY WINDS TO FALL FROM 15- 20 KTS ON FRI TO 10-15 KTS ON
SAT AND SUN. 2-3 FT SEAS ON WED ALONG OUR COASTAL WATERS INCREASE TO
3-5 FT THURS NIGHT IN RESPONSE TO THE STRONGER WINDS WITH SEAS THEN
LOWERING DOWN TO 2-4 FT ON FRI AND 2-3 FT FOR THE WEEKEND AS WINDS
EASE. DIURNAL SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE THROUGH THE
