NWS Raleigh, NC wrote its last area forecast discussion before the first event at Jul 2, 3:48 AM EST, 4 hours 47 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RALEIGH NC 448 AM EDT TUE JUL 2 2013 .SYNOPSIS... THE COMBINATION OF A WARM HUMID AIR MASS AND A SERIES OF UPPER LEVEL DISTURBANCES ALOFT WILL CAUSE PERIODS OF HEAVY SHOWERS AND THUNDERSTORMS ACROSS CENTRAL NC THROUGH WEDNESDAY NIGHT. && .NEAR TERM /THROUGH WEDNESDAY/... AS OF 315 AM TUESDAY... ...FLASH FLOOD WATCH EXTENDED UNTIL WEDNESDAY EVENING FOR AREAS GENERALLY ALONG AND WEST OF US HWY 1 AND CONTINUING UNTIL THIS AFTERNOON ALONG THE I-95 CORRIDOR... DEEP SOUTH/SOUTHWESTERLY FLOW FROM THE GULF OF MEXICO AND CARIBBEAN... CONTINUES TO TRANSPORT A PLUME OF HIGH MOISTURE CONTENT AIR NORTHWARD AND INTO OUR REGION THIS MORNING... WITH THE HIGHEST PW'S AROUND 2-2.25 INCHES ACROSS EASTERN NORTH CAROLINA. EXPECT THIS ATMOSPHERIC RIVER OF MOIST AIR TO CONTINUE OVER THE NEXT SEVERAL DAYS... WITH THE 2+ INCH PW'S EXPECTED TO SLOWLY SHIFT WESTWARD ACROSS THE ENTIRE AREA BY THIS AFTERNOON AND THIS EVENING... WITH AXIS OF 2+ INCH PW'S EXPECTED TO BE ACROSS OUR PIEDMONT/WESTERN PIEDMONT COUNTIES BY WEDNESDAY... WITH POSSIBLY A BIT DRIER AIR WORKING INTO EASTERN PORTIONS OF OUR AREA BY TONIGHT AND WEDNESDAY AS THE WESTERN ATLANTIC RIDGE SLOWLY SHIFTS WESTWARD... ALONG WITH THE CLOSED LOW CURRENTLY NEAR ST LOUIS. THIS WILL ALLOW THE AXIS OF POSSIBLE HEAVY RAIN TO SHIFT WESTWARD AT BIT TODAY AND ESPECIALLY BY WEDNESDAY. GIVEN THE DEPTH OF THE LCL TO FREEZING LEVEL... EXPECT WARM RAIN PROCESSES WILL CONTINUE TO PROVIDE OUR AREA WITH A HEAVY RAIN THREAT FOR TODAY THROUGH WEDNESDAY... WITH LOCATIONS ACROSS THE WESTERN HALF/TWO-THIRDS STANDING THE BEST CHANCE OF SEE FLASH FLOODING. THUS... PLAN TO EXTEND THE FLASH FLOOD WATCH ACROSS THE WESTERN TWO-THIRDS OF THE AREA (ALL BUT THE COASTAL PLAIN COUNTIES... NEAR I-95) UNTIL 00Z THURSDAY. WRT CURRENT SHOWERS AND STORMS... WE MAY SEE AN UPTICK IN ACTIVITY FROM SOUTH TO NORTH ACROSS THE ENTIRE AREA (ESPECIALLY WEST) AS WE GET CLOSER TO DAY BREAK AS ANOTHER WEAK SUBTLE S/W LIFTS NORTHWARD FROM GA/SC THIS MORNING. THEN SUBSEQUENT WEAK IMPULSES IN THE DEEP SOUTH/SOUTHWESTERLY FLOW ALOFT WILL TRACK A BIT FURTHER WEST... ALONG WITH A BIT OF BACKING OF THE LOW LEVEL WINDS. THIS MAY POSSIBLY AIDE IN THE LIFT... VIA UPSLOPE FLOW (ESPECIALLY ACROSS THE NORTHWEST PIEDMONT LATE TODAY AND TONIGHT). IN ADDITION... TO MORE OF AN ENHANCED FLASH FLOOD THREAT FROM THE BACKED WINDS AND 30 TO 40 KT 925 MB WINDS.... EXPECT WE WILL HAVE A WEAK TORNADO THREAT AND DAMAGING WIND THREAT... AS DEEP LAYER SHEAR WILL AGAIN BE IN THE 25 TO 40 KT RANGE... WITH 0-1 KM SRH IN THE 125 TO 175 M2/S2 AND LOW LCL'S THANKS TO THE TROPICAL LIKE AIRMASS. THE ONE POSSIBLE FLY IN THE OINTMENT SO TO SPEAK... WILL BE THE AMOUNT OF DESTABILIZATION WHICH IS ABLE TO OCCUR THIS AFTERNOON. GIVEN THE WIDESPREAD CLOUD COVER WE MAY BE HARD PRESSED TO SEE MORE THAN 400-600 J/KG OF MLCAPE ACROSS THE PIEDMONT/WESTERN PIEDMONT... WHERE THE 0-1 KM SRH IS FAVORABLE. THUS... SPC HAS JUST ADDED A 2 PERCENT TOR THREAT TO THE DAY 1 OUTLOOK. ANY TOR THREAT APPEARS TO BE BEST THIS AFTERNOON INTO THE EVENING AS WELL... WITH LESS OF A THREAT ON WEDNESDAY. EXPECT HIGH TEMPS TODAY WILL BE HAMPERED GREATLY BY THE CLOUD COVER AND PRECIP. THUS... WILL GO WITH HIGHS IN THE UPPER 70S WEST TO THE LOWER TO MID 80S FAR EAST/SOUTHEAST... WHERE WE MAY SEE A FEW MORE BREAKS IN THE CLOUD COVER. LOWS TONIGHT ARE AGAIN EXPECTED TO BE GENERALLY AROUND 70 TO LOWER 70S... WITH PERHAPS A FEW MID 70S SOUTHEAST. HIGHS WEDNESDAY IN THE 80-87 DEGREE RANGE FROM WEST TO EAST... WITH AGAIN GOOD CHANCES FOR SHOWERS AND STORMS... ESPECIALLY WEST. && .SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/... AS OF 330 AM TUESDAY... WEDNESDAY NIGHT THROUGH FRIDAY...WESTERN ATLANTIC RIDGE WILL BUILD WESTWARD THIS PERIOD ALONG WITH ITS ASSOCIATED BERMUDA HIGH. THIS WILL AID TO PUSH MOISTURE PLUME INITIALLY OVER THE WESTERN FRINGE OF OUR FORECAST AREA FARTHER WEST INTO FAR WESTERN NC-EASTERN TN. WHILE THE WARMING ALOFT AND DRIER AIR IN THE MID-UPPER LEVELS WILL HELP TO LIMIT CONVECTIVE DEVELOPMENT FOR THE MOST PART...RESIDUAL MOISTURE STILL PLENTIFUL ENOUGH TO GENERATE AT LEAST SCATTERED CONVECTION OVER THE PIEDMONT THURSDAY AFTERNOON. EXPECT TO SEE A MORE NOTICEABLE DOWNWARD TREND IN CONVECTIVE DEVELOPMENT FRIDAY AFTERNOON. WITH CONVECTIVE COVERAGE WANING AND SLIGHTLY BETTER POTENTIAL FOR EXTENDED PERIODS OF PARTIAL SUN...AFTERNOON TEMPS WILL BE RETURNING TO NORMAL LEVELS. EXPECT MORE CLOUDS THAN SUN IN THE FAR WEST THURSDAY WHICH WILL LIMIT NORMAL DIURNAL TREND. MAX TEMPS THURSDAY LOW-MID 80S WEST TO UPPER 80S COASTAL PLAIN AND SANDHILLS. MAX TEMPS FRIDAY MID-UPPER 80S. && .LONG TERM /SATURDAY THROUGH MONDAY/... AS OF 330 AM TUESDAY... SATURDAY THROUGH MONDAY...MID-UPPER LEVEL RIDGE WILL CONTINUE TO BUILD INTO NC WITH THE CENTER OF MID-UPPER LEVEL ANTI-CYCLONE PROJECTED TO BE DIRECTLY OVERHEAD SUN-MON. THIS PATTERN USUALLY RESULTS IN HOT/HUMID CONDITIONS. WILL ADVERTISE SUCH A TREND WITH AFTERNOON HIGH TEMPS NEAR 90-LOWER 90S EXPECTED SUNDAY-MONDAY. WHILE TOP SOIL MOISTURE CAN HAVE AN IMPACT ON DAYTIME TEMPS...REVIEW OF DAILY PRECIP AMOUNTS SUGGEST THAT THE HEAVY RAIN HAS BEEN CONCENTRATED IN POCKETS. THUS EXPECT ENOUGH DRYING TO OCCUR THU-SAT IN THE COASTAL PLAIN-SANDHILLS TO ALLOW TEMPS TO SOLIDLY REACH THE LOWER 90S BY THE END OF THE WEEKEND. CAPPING INVERSION ASSOCIATED THE MID-UPPER RIDGE WILL LIMIT/INHIBIT MOST CONVECTIVE DEVELOPMENT. STILL...WITH SLIGHT TO MODERATE SFC BASED INSTABILITY IN PLACE...ISOLATED CONVECTION STILL PROBABLE THIS WEEKEND. && .AVIATION /12Z TUESDAY THROUGH SATURDAY/... AS OF 440 AM TUESDAY... IFR/LOW END MVFR CIGS HAVE DEVELOPED ACROSS THE AREA AGAIN THIS MORNING IN THE DEEP SOUTHERLY FLOW ACROSS THE REGION... ALONG WITH SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS MOVING ACROSS THE REGION FROM TIME TO TIME IN A GENERAL SOUTH TO NORTH FASHION. EXPECT THE CIGS WILL BE SLOW TO RECOVER TODAY... MAYBE NOT EVEN REACHING VFR AT KGSO/KINT/KRDU. WE SHOULD SEE PERIODS OF ENHANCED SHOWERS AND STORMS FROM TIME TO TIME THE AFTERNOON INTO TONIGHT/EARLY WEDNESDAY. HOWEVER... CONFIDENCE IN THE TIMING OF THE BEST COVERAGE TODAY IS STILL IN QUESTION. THUS... WILL CONTINUE TO MENTION LONG PERIODS OF VCSH AND VCTS IN THE TAFS FROM THIS MORNING ONWARD. EXPECT LOCATIONS THAT REACH VFR TODAY OR EARLY THIS EVENING WILL QUICKLY FALL BACK INTO THE MVFR/IFR RANGE MID TO LATE EVENING INTO THE EARLY HOURS OF WEDNESDAY... WITH SHOWERS/STORMS BECOMING MORE SCATTERED EAST TO WEST. AVIATION CONDITIONS SHOULD IMPROVE FROM EAST TO WEST STARTING WEDNESDAY NIGHT/THURSDAY AS DRIER AIR TO OUR EAST STARTS TO PUSH WESTWARD INTO ERN/CENTRAL NC. ALTHOUGH WE SHOULD STILL SEE A GOOD CHANCE OF MVFR TO IFR CONDITIONS LATE NIGHT-EARLY MORNING EACH DAY THROUGH SATURDAY... ALONG WITH A CHANCE OF AFTERNOON/EVENING SHOWERS AND STORMS. && .RAH WATCHES/WARNINGS/ADVISORIES... FLASH FLOOD WATCH THROUGH THIS AFTERNOON FOR NCZ011-027-028- 042-043-078-089.
