WHAT HAS CHANGED
TORNADO WATCH HAS BEEN ISSUED FOR PORTIONS OF NORTHEAST SOUTH
CAROLINA AND ALL OF SOUTHEAST NORTH CAROLINA AS A BAND OF
SHOWERS AND STORMS MOVES THROUGH FROM WEST TO EAST WITH AN
ATTENDANT THREAT FOR ISOLATED TORNADOES AND DAMAGING WIND GUSTS.
THE SEVERE THREAT WILL END BEHIND THIS BAND.
FLOOD WATCH HAS EXPIRED FOR THE COASTAL SOUTHEAST NC COUNTIES AS
THE THREAT FOR TRAINING HEAVY SHOWERS AND STORMS HAS ENDED. A
FINAL BAND OF HEAVY SHOWERS AND STORMS IS PROGRESSING EASTWARD
AND WILL AFFECT THE AREA EARLY THIS AFTERNOON, BUT SHOULD MOVE
THROUGH FAST ENOUGH TO PRECLUDE IMPACTFUL FLASH FLOODING.
NEVERTHELESS, TYPICAL LOW-LYING PROBLEM SPOTS MAY OBSERVE MINOR
FLOODING.
KEY MESSAGES
- 1) ISOLATED TO SCATTERED HEAVY RAIN PERSISTS AT TIMES INTO
THIS AFTERNOON. A FEW AREAS COULD SEE FLASH FLOODING AS A
RESULT, ESPECIALLY ACROSS NC COASTAL AREAS. ISOLATED
TORNADOES ARE POSSIBLE.
- 2) HAZARDOUS SURF CONDITIONS AND TIDAL FLOODING WILL CONTINUE
THROUGHOUT THE WEEKEND.
- 3) HAZARDOUS MARINE CONDITIONS WILL CONTINUE THROUGH THIS
WEEKEND.
DISCUSSION
KEY MESSAGE 1...ISOLATED TO SCATTERED HEAVY RAIN PERSISTS AT
TIMES INTO THIS AFTERNOON. A FEW AREAS COULD SEE FLASH FLOODING
AS A RESULT, ESPECIALLY ACROSS NC COASTAL AREAS. ISOLATED
TORNADOES ARE POSSIBLE.
WARM FRONT HAS NOW CLEARED THE FORECAST AREA, PER DEWPOINT
OBSERVATIONS. A LACKADAISICAL LINE OF SHOWERS JUST BEHIND THE
FRONT HAS BEEN SWEEPING FROM SOUTH TO NORTH ACROSS THE AREA,
CURRENTLY MAKING ITS WAY THROUGH THE PEE DEE AND NC COASTAL
PLAIN REGIONS.
ADMITTEDLY, EVERY PIECE OF GUIDANCE I'VE LOOKED AT HAS BEEN
ABSOLUTELY TERRIBLE IN HANDLING THIS SETUP. WARM FROPA WAS
SUPPOSED TO IGNITE INSTABILITY AND CREATE A MORE CONVECTIVE
ENVIRONMENT EARLIER THIS EVENING, BUT THAT NEVER MATERIALIZED. I
DON'T THINK I'VE SEEN A SINGLE FLASH OF LIGHTNING OVER LAND, AND
THERE HAVE ONLY BEEN A SMALL HANDFUL OF STRIKES OVER THE WATERS
60-80 NM OFFSHORE. I BELIEVE THE CAD WEDGE FROM EARLIER TONIGHT
WON THE BATTLE OVER THE WARM FRONT AND KEPT IN FAR MORE
STABILITY THAN MODELS WERE SHOWING. EVEN NOW AFTER 2 AM EDT, THE
CONVECTIVE-ALLOWING MODELS ARE TRYING TO BLOW UP STORMS THAT ARE
NOT REPRESENTED ON CURRENT RADAR TRENDS, DESPITE AN OVERALL
INCREASE IN RAIN.
SPOTTY SHOWERS WILL CONTINUE THIS MORNING, WHILE THE STAGE IS
SET FOR ONE MORE LINE OF RAIN THAT WILL PUSH THROUGH FROM WEST
TO EAST LATE THIS MORNING INTO THIS AFTERNOON (SAID LINE IS
CURRENTLY IN EASTERN GA).
HERE WE SIT AGAIN WITH THE FRUSTRATING FORECAST UNCERTAINTY. ON
ONE HAND, THERE CERTAINLY IS ENOUGH MOISTURE AND FORCING IN THE
ATMOSPHERE TO SUGGEST HIGH RAINFALL RATES CAPABLE OF FLASH
FLOODING. MEANWHILE, THE ENVIRONMENT IS STILL CAPABLE OF A
TORNADO THREAT. PLENTY OF LOW LCLS TO GO AROUND, SBCAPE WILL BE
ON THE RISE AFTER THE SUN RISES, AND 0-1 KM SRH MAY PUSH ABOVE
150 M2/S2 AS THIS CONVECTIVE LINE PUSHES THROUGH. YET ON THE
OTHER HAND, GUIDANCE HANDLING THIS EVENT EXTREMELY POORLY
DOESN'T GIVE ME MUCH CONFIDENCE MOVING FORWARD HERE. WILL BE
CURIOUS TO SEE HOW MUCH THE SBCIN AND MLCIN HOLDS ON AS THE SUN
RISES AND THIS LINE MOVES THROUGH. THE TORNADO AND FLOODING
THREATS STILL CANNOT BE IGNORED, GENERALLY FROM 8 AM - 4 PM EDT
TODAY FROM WEST TO EAST.
AFTER THIS LINE MOVES THROUGH, DRY AIR WILL START TO BREAK
THROUGH THE CLOUD COVER. FORECAST DRIES OUT THIS AFTERNOON AND
EVENING. LOWS TONIGHT IN THE LOW-TO-MID 60S. DRY FORECAST LOOKS
TO DOMINATE FOR MUCH OF THIS WEEK.
KEY MESSAGE 2...HAZARDOUS SURF CONDITIONS AND TIDAL FLOODING
WILL CONTINUE THROUGHOUT THE WEEKEND.
HAZARDS IN EFFECT:
- COASTAL FLOOD ADVISORY FROM 7 AM EDT TO 10 AM EDT THIS
MORNING FOR THE ENTIRE COASTLINE FROM COASTAL PENDER COUNTY,
NC TO GEORGETOWN COUNTY, SC.
- COASTAL FLOOD ADVISORY FROM 9 AM EDT TO 1 PM EDT THIS MORNING
FOR THE LOWER CAPE FEAR RIVER, INCLUDING DOWNTOWN WILMINGTON.
- A HIGH RISK FOR RIP CURRENTS IS IN EFFECT FROM 6 AM EDT THIS
MORNING THROUGH THIS EVENING FOR ALL BEACHES ALONG NORTHEAST
SC AND SOUTHEAST NC.
NO CHANGES TO THE PREVIOUS THINKING REGARDING COASTAL IMPACTS
TODAY. THE INCREASED ONSHORE WINDS WILL YIELD ROUGH SURF AND
STRONG RIP CURRENTS. LARGE BREAKING WAVES OF 4 TO 6 FT EXPECTED
ALONG THE BEACHES IN SOUTHEAST NC. WAVE-RUNUP MAY ALSO CAUSE
MINOR TO MODERATE BEACH EROSION, ESPECIALLY THOSE BEACHES WITH A
WEAKENED SHORELINE STRUCTURE WITH HIGH TIDE. ROUGH SURF MAY
LINGER INTO MONDAY, BUT SHOULD IMPROVE AS THE WINDS BECOME MORE
FAVORABLE.
THE WINDS COUPLED WITH THE HIGH ASTRONOMICAL TIDES DURING THE
NEXT SEVERAL HIGH TIDE CYCLES MAY LEAD TO MINOR COASTAL
FLOODING INTO EARLY NEXT WEEK ALONG ALL AREA BEACHES AND THE
LOWER CAPE FEAR RIVER, INCLUDING DOWNTOWN WILMINGTON.
KEY MESSAGE 3...HAZARDOUS MARINE CONDITIONS WILL CONTINUE
THROUGH THIS WEEKEND.
- A SMALL CRAFT ADVISORY IS IN EFFECT UNTIL 2 AM EDT MONDAY FOR
THE COASTAL WATERS FROM LITTLE RIVER INLET, SC TO SOUTH SANTEE
RIVER, SC OUT 20 NM. THIS ADVISORY IS ALSO IN EFFECT UNTIL 8
AM EDT MONDAY FOR THE COASTAL WATERS FROM SURF CITY, NC TO
LITTLE RIVER INLET, SC OUT 20 NM.
SEE MARINE SECTION BELOW FOR MORE DETAIL.
AVIATION /14Z SUNDAY THROUGH THURSDAY/
SUB-VFR CIGS WITH INTERMITTENT VSBY RESTRICTIONS IN RAIN TO 2-4
SM. BY 15Z CIGS SHOULD HAVE LIFTED TO MVFR WITH ANOTHER LINE OF
STORMS MOVING ACROSS THE AREA IN THE AFTERNOON. SOUTHERLY WINDS
WILL BECOME GUSTY, GENERALLY 20-25 KTS. SKIES WILL FINALLY
BEGIN TO BREAK UP FROM WEST TO EAST BEHIND THE LINE THROUGH THE
AFTERNOON AS DRY AIR MOVES INTO THE AREA, WITH DRY CONDITIONS
AFTER 00Z. GUSTS COME DOWN BY 01-03Z MONDAY.
EXTENDED OUTLOOK...VFR SHOULD RETURN AS DRY AIR FILTERS IN LATE
SUNDAY AND PREVAIL THROUGH THURSDAY.
MARINE
THROUGH THURSDAY...FRESH TO STRONG BREEZE OUT OF THE SSE WILL
GRADUALLY VEER TO THE S THIS MORNING, TO SW THIS EVENING, TO W
BY MONDAY MORNING. ONCE THE ADVISORIES EXPIRE BY MONDAY MORNING,
WINDS WILL CONTINUE TO IMPROVE TO A MODERATE BREEZE OUT OF THE
NW MONDAY AFTERNOON, EVEN FURTHER TOWARDS A GENTLE BREEZE OUT OF
THE N BY MONDAY NIGHT. SEAS ALSO QUICKLY IMPROVE FROM 3-6 FT
MONDAY TO 2-4 FT TUESDAY. GENTLE BREEZE EXPECTED TO CONTINUE
THROUGH THURSDAY, BECOMING VARIABLE AT TIMES. SEAS CONTINUE TO
IMPROVE TOWARDS 1-3 FT.
