AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
138 PM EST FRI NOV 7 2025
SYNOPSIS
A WARM FRONT WILL CONTINUE TO RETREAT NORTHWARD AND ACROSS NC THIS
AFTERNOON AND EVENING. ANOTHER WEAK FRONT WILL SETTLE ACROSS THE
CAROLINAS SATURDAY AND STALL THERE THROUGH SATURDAY NIGHT. A MUCH
STRONGER, ARCTIC COLD FRONT WILL MOVE ACROSS THE REGION EARLY SUNDAY
NIGHT.
NEAR TERM /THROUGH TONIGHT/
AS OF 138 PM FRIDAY...
SFC ANALYSIS THIS AFTERNOON DEPICTED A WAVY WARM FRONT DRAPED ACROSS
OUR CENTRAL COASTAL PLAIN WEST TOWARDS THE WESTERN PIEDMONT.
EMBEDDED WITHIN A SLY WAA REGIME, STRATOCU HAS BLOSSOMED ACROSS MOST
OF CENTRAL NC WHILE LIGHT RAIN HAS REMAINED TO OUR EAST NEAR CAPE
LOOKOUT. EXPECT THE STRATOCU TO PERSIST THROUGH SUNSET WITH DRY
CONDITIONS THROUGH EARLY TONIGHT.
FURTHER UPSTREAM, A LINE OF PRE-FRONTAL CONVECTION WAS DRAPED ACROSS
WEST-CENTRAL TN NORTHWEST THROUGH WESTERN PA. THIS LINE OF SHOWERS
AND STORMS WILL WEAKEN EARLY TONIGHT AS IT CROSSES THE SOUTHERN
APPALACHIANS. WHILE MOISTURE AND UPPER FORCING WILL INCREASE ACROSS
CENTRAL NC TONIGHT, INSTABILITY WILL BE LACKING. AS SUCH, EXPECT ANY
LIGHT RAIN THAT DOES MAKE IT ACROSS THE MOUNTAINS TO DISSIPATE OUT
WITH EASTWARD EXTENT ACROSS CENTRAL NC THROUGH SATURDAY MORNING.
STILL COULD SEE A FEW HUNDREDS TO MAYBE A TENTH OF AN INCH OF RAIN
IN THE WESTERN/SOUTHERN PIEDMONT, WITH LESS AMOUNTS FURTHER EAST.
WINDS TONIGHT SHOULD BE RELATIVELY LIGHT BUT CAN'T RULE OUT A
DIABATICALLY-ENHANCED GUST OF 20 TO 30 MPH OR SO WITH THE DECAYING
RAIN. OTHERWISE, MULTI-LAYERED CLOUDINESS WILL ACCOMPANY THE
DECAYING CONVECTION WITH WARM OVERNIGHT LOWS IN THE LOWER TO MID 50S
EXPECTED.
SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/
AS OF 110 PM FRIDAY...
OVERVIEW: ALOFT, THE LOW OVER HUDSON BAY WILL GRADUALLY DROP SWD
ACROSS ONTARIO AND THE GREAT LAKES THROUGH SUN NIGHT. MEANWHILE, A
S/W WILL LIFT ACROSS THE AREA EARLY SAT. AS ANOTHER S/W SWINGING EWD
ACROSS THE OH VALLEY HELPS AMPLIFY THE LONGWAVE TROUGH TO THE WEST
SAT NIGHT/EARLY SUN, A SRN STREAM DISTURBANCE WILL LIFT NEWD ALONG
THE SOUTHEAST US/CAROLINA COAST. BY MONDAY MORNING, THE LOW SHOULD
BE OVER THE GREAT LAKES/OH VALLEY, WITH THE TROUGH AXIS EXTENDING
SWD TO THE GULF. AT THE SURFACE, THE COLD FRONT APPROACHING FROM THE
NORTH-NORTHWEST SAT WILL SLOW IN ITS PROGRESSION AS THE PARENT LOW
OCCLUDES OVER SOUTHEAST CANADA. THE FRONT SHOULD MAKE IT INTO THE
AREA BECOMING QUASI-STATIONARY AND MORE W-E ORIENTED DURING THE DAY
SAT AS AN AREA OF LOW PRESSURE TRACKING NEWD ALONG THE FRONT
APPROACHES FROM THE SOUTHWEST. THIS LOW WILL HELP THE FRONT LIFT
NORTHWARD ACROSS THE AREA AS A WARM FRONT LATE SAT/SAT NIGHT AS
ANOTHER, STRONGER LOW TRACKS EWD FROM THE MID-MS VALLEY ACROSS THE
OH VALLEY. THE LOWS MAY MERGE OVER THE NRN MID-ATLANTIC/NORTHEAST US
ON SUN, THE TRAILING COLD FRONT FINALLY PUSHING THROUGH THE AREA
FROM W-E SUN AFT/EVE. ARCTIC HIGH PRESSURE WILL BUILD INTO THE
REGION IN THE WAKE OF THE FRONT SUN NIGHT.
PRECIPITATION: THE MOISTURE ASSOCIATED WITH THE INITIAL COLD FRONT
EARLY SAT DECREASES AS IT MOVES INTO THE AREA, SO WHILE THERE MAY BE
A STRAY SHOWER EARLY, LARGELY EXPECT SAT TO BE DRY. AS THE WARM
FRONT AND SURFACE LOW LIFT ACROSS THE AREA SAT EVE/NIGHT, CHANCES
FOR SHOWERS WILL INCREASE A BIT, MAINLY ACROSS THE SOUTH AND EAST
(IN THE WARM SECTOR). THERE IS SOME INSTABILITY (NAM) SAT EVE/NIGHT
AS THE LOW LIFTS THROUGH, SO HAVE KEPT IN MENTION FOR SLIGHT CHANCE
THUNDER, MAINLY SOUTH AND EAST WHERE THE LLJ ALSO STRENGTHENS AS IT
PROGRESSES ENEWD ACROSS THE REGION. THERE MAY BE A LULL IN
PRECIPITATION BETWEEN THE LOW AND THE FROPA. THERE IS STILL SOME
UNCERTAINTY WRT CONVECTION ALONG THE COLD FRONT SUN AFT/EVE. THE GFS
CONTINUES BE THE MOST BULLISH WITH THE INSTABILITY, SHOWING UP TO
1000 J/KG OF MLCAPE MAXIMIZED OVER ALONG AND EAST OF THE I-95
CORRIDOR SUN AFT/EVE, AND BULK SHEAR OF 40-50 KTS IN THAT AREA.
THERE IS A MARGINAL RISK FROM THE SPC FOR THAT TIME AND LOCATION.
TEMPERATURES: HEADLINE UP FRONT, A DRASTIC DROP IN TEMPERATURES IS
EXPECTED SUN NIGHT. ABOVE TO WELL ABOVE NORMAL TEMPERATURES EXPECTED
FOR SAT, SAT NIGHT, AND SUN. HIGHS IN THE LOW TO MID 70S SAT SHOULD
INCREASE A COUPLE/FEW DEGREES FOR SUN. LOWS SAT NIGHT, LOW/MID 50S
TO LOW 60S. TEMPERATURES WILL QUICKLY FALL IN THE WAKE OF THE COLD
FRONT SUN EVE/NIGHT, WITH MID/UPPER 30S NW TO MID 40S SE BY DAYBREAK
MON. WHILE THOSE LOWS ARE NEAR NORMAL FOR EARLY NOV, THEY ARE ABOUT
15 DEGREES LOWER THAN SAT NIGHT LOWS.
LONG TERM /MONDAY THROUGH THURSDAY/
AS OF 1100 PM THURSDAY...
* BELOW NORMAL TEMPERATURES ARE EXPECTED BEHIND BEHIND A STRONG
ARCTIC COLD FRONT TO START THE NEXT WEEK. A HARD FREEZE MONDAY
NIGHT IS EXPECTED WITH LOWS MOSTLY IN THE 20S ACROSS CENTRAL NC.
* DRY WEATHER AND WARMING TEMPS ARE EXPECTED FOR MID TO LATE WEEK.
SOME OF THE COLDEST AIR OF THE SEASON IS EXPECTED TO SURGE INTO
CENTRAL NC ON MONDAY INTO MONDAY NIGHT BEHIND A STRONG ARCTIC COLD
FRONT THAT IS EXPECTED TO MOVE ACROSS THE AREA ON SUNDAY NIGHT,
PROPELLED BY A STRONG HIGHLY ANOMALOUS TROUGH MOVING ACROSS THE
REGION EARLY NEXT WEEK. THE ANOMALOUSLY DEEP TROUGH WILL SHIFT TO
THE EAST OF THE AREA BY MID WEEK, WITH WSW LOW LEVEL RETURN FLOW
EXPECTED BY MID WEEK.
LOW TEMPERATURE MONDAY NIGHT WILL BE THE BIG STORY DURING THIS
PERIOD, WITH LOW TEMPERATURES EXPECTED TO FALL INTO THE MID/UPPER
20S TO NEAR 30 DEGREES ACROSS MOST, IF NOT ALL, LOCATIONS ACROSS
CENTRAL NC. OTHERWISE, DRY WEATHER IS GENERALLY EXPECTED WITH BELOW
NORMAL TEMPS TO START THE WEEK, WARMING TO NEAR NORMAL BY MID/LATE
WEEK. THIS WILL RESULT IN HIGHS RANGING FROM THE MID 40 TO GENERALLY
LOWER 50S EARLY NEXT WEEK, BEFORE WARNING INTO THE UPPER 50S TO 60S
BY MID/LATE NEXT WEEK. LOW TEMPS WILL FOLLOW A SIMILAR TREND, WITH
LOWS IN THE 30S TUESDAY NIGHT TO AROUND 40 FOR WEDNESDAY NIGHT.
AVIATION /18Z FRIDAY THROUGH WEDNESDAY/
AS OF 115 PM FRIDAY...
EMBEDDED WITHIN A WAA REGIME, STRATOCU HAS LARGELY BLOSSOMED ACROSS
CENTRAL NC THIS AFTERNOON. LOW VFR CEILINGS SHOULD LARGELY PERSIST
THIS AFTERNOON BEFORE DISSIPATING NEAR OR JUST AFTER SUNSET. MULTI-
LAYERED CLOUDINESS WILL THEN ACCOMPANY A BROKEN LINE OF CONVECTION
THAT WILL LARGELY DECAY ACROSS THE SOUTHERN APPALACHIANS LATER
TONIGHT. SOME RESIDUAL LIGHT RAIN MAY REACH KINT/KGSO OR KRDU/KFAY
THROUGH EARLY TONIGHT POSSIBLY INDUCING BRIEF VISIBILITY
RESTRICTIONS AND/OR CEILINGS. THERE WILL ALSO BE A CHANCE OF LOW-
LEVEL WIND SHEAR, AS A 35-45 KT, SWLY LOW-LEVEL JET TRAVERSES THE
REGION ATOP A RELATIVELY STABLE NEAR SURFACE LAYER AND INVERSION.
ANY BRIEF RESTRICTIONS SHOULD QUICKLY LIFT TO VFR BY SATURDAY
MORNING AND PERSIST THROUGH THE END OF THE 24 HR TAF PERIOD.
OUTLOOK: THERE WILL BE A CHANCE OF FLIGHT RESTRICTIONS AND PERHAPS
SCATTERED, ELEVATED CONVECTION (SHOWERS WITH LIMITED PROBABILITY OF
THUNDER) LATE SAT INTO SUN MORNING, FOLLOWED BY YET ANOTHER CHANCE
OF FRONTAL CONVECTION AND POST-FRONTAL RAIN AND RELATED FLIGHT
RESTRICTIONS WITH THE PASSAGE OF A STRONG COLD FRONT LATE SUN AND
SUN NIGHT. ADDITIONALLY, STRONG AND GUSTY SWLY SURFACE WINDS WILL
RESULT AHEAD OF THAT COLD FRONT ON SUN, FOLLOWED BY SIMILARLY STRONG
AND GUSTY NWLY ONES BEHIND IT SUN NIGHT AND MON.
