AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
145 AM EST TUE NOV 11 2025
SYNOPSIS
A STRONG UPPER LEVEL TROUGH CROSSING THE REGION WILL PUSH OFF THE
COAST THIS MORNING, WITH CHILLY HIGH PRESSURE MOVING IN FROM THE
SOUTHWEST DURING THE DAY. THIS HIGH WILL SLOWLY BUILD OVER THE
SOUTHEAST STATES THROUGH THE WORK WEEK, ALLOWING FOR A GRADUAL
WARMUP BACK TO NEAR NORMAL TEMPERATURES BY FRIDAY.
NEAR TERM /TODAY THROUGH TONIGHT/
AS OF 145 AM TUESDAY...
* A HARD FREEZE THIS MORNING WILL END THE GROWING SEASON.
* ANOTHER CHILLY DAY EXPECTED WITH BRISK WINDS AND BELOW NORMAL
TEMPERATURES.
VIGOROUS SHORTWAVE ENERGY CROSSING THE AREA THROUGH THE BASE OF THE
NEAR-RECORD DEEP TROUGH CONTINUES TO TRIGGER AREAS OF LIGHT SNOW,
AIDED BY DEEP MIXING AND STEEP LOW LEVEL LAPSE RATES. THIS
PRECIPITATION WILL REMAIN GENERALLY LIGHT, PERHAPS LEADING TO
ISOLATED SPOTS OF A LIGHT DUSTING ON GRASS BUT LITTLE ELSE, GIVEN
THE WARM PAVEMENT. WE WILL CONTINUE TO SEE AN ENHANCEMENT IN SURFACE
WINDS AND GUSTS JUST AHEAD OF AND WITH THESE LIGHT SNOW AREAS. THE
TROUGH IS EXPECTED TO SHIFT E OF THE AREA BY MID MORNING, AND WILL
BE FOLLOWED BY MOSTLY CLEAR SKIES WITH JUST SCATTERED MID CLOUDS AT
MOST THROUGH THE DAY AS SUBSIDENCE TAKES OVER AND DEEPENS. COLD
SURFACE HIGH PRESSURE WILL BUILD IN FROM THE SW, BUT THE TIGHT MSLP
GRADIENT BETWEEN IT AND LOW PRESSURE OVER NEW ENGLAND WILL KEEP US
IN A BLUSTERY PATTERN WITH FREQUENT GUSTS TO 20-30 MPH UNTIL LATE
AFTERNOON, WHEN SURFACE WINDS WILL DIMINISH WITH THE ONSET OF
DECOUPLING. WITH CONTINUED CAA, LOW LEVEL THICKNESSES WILL BE ~70 M
BELOW NORMAL, SUPPORTING HIGHS OF 45-50, DESPITE GOOD INSOLATION.
SKIES WILL BE FAIR HEADING INTO THIS EVENING WITH RAPID COOLING AS
THE SURFACE WINDS FALL OFF. HOWEVER, A BATCH OF MID LEVEL MOISTURE
NOW OVER THE MIDWEST AND ASSOCIATED WITH A WARM FRONT ALOFT IS
EXPECTED TO CROSS THE MID ATLANTIC REGION AND NC TONIGHT, RESULTING
IN A PERIOD OF PARTLY TO MOSTLY CLOUDY SKIES, MAINLY OVER NORTHERN
SECTIONS. AND BASED ON THE FAVORABLE VERTICAL THERMAL STRUCTURE,
INCLUDING HIGH LOW-MID LEVEL STABILITY, WINDS INCREASING WITH HEIGHT
TO FAST WNW MID LEVEL FLOW, AND LOW PRESSURE TO OUR NNE WITH RIDGING
TO OUR W, SOME OROGRAPHIC ENHANCEMENT OF THESE CLOUDS IS LIKELY.
THIS SHOULD RESULT IN A LESS-COLD NIGHT, BUT STILL BELOW NORMAL,
WITH LOWS GENERALLY 30-35. -GIH
SHORT TERM /WEDNESDAY AND WEDNESDAY NIGHT/
AS OF 252 PM MONDAY...
TO BE UPDATED SHORTLY.
LONG TERM /THURSDAY THROUGH MONDAY/
AS OF 252 PM MONDAY...
WHILE A COLD FRONT WILL COME THROUGH ON WEDNESDAY, VERY DRY AIR
SHOULD PREVENT ANY PRECIPITATION FROM OCCURRING, WITH EVEN CLOUD
COVER MINIMAL ALONG THE FRONTAL PASSAGE. THE WIND VALUES ON
WEDNESDAY WILL BE SIMILAR TO TUESDAY, WITH THE SUSTAINED WIND AROUND
10 MPH AND GUSTS AROUND 20 MPH. FIRE WEATHER CONCERNS COULD PERSIST
WITH THE HIGHER WINDS. WITH HIGH PRESSURE ACROSS THE SOUTHEASTERN
UNITED STATES THROUGH MUCH OF THE WEEK, THERE WILL NOT BE A CHANCE
FOR PRECIPITATION UNTIL SUNDAY AT THE EARLIEST, AND MODELS ARE
SUGGESTING THAT THE BETTER CHANCE FOR PRECIPITATION WON'T COME UNTIL
MONDAY. LOW PRESSURE IS LIKELY TO MOVE OVER NEW ENGLAND, DRAGGING A
COLD FRONT ACROSS THE APPALACHIANS MONDAY. AS THE WIND SHIFTS TO THE
SOUTHWEST ON WEDNESDAY, THIS SHOULD MODERATE TEMPERATURES, AND MOST
LOCATIONS SHOULD RETURN TO THE LOW 60S BY WEDNESDAY. BY THE WEEKEND,
SOME 70S WILL RETURN. LOWS WILL BE IN THE UPPER 30S AND 40S.
AVIATION /06Z TUESDAY THROUGH SATURDAY/
AS OF 1255 AM TUESDAY...
VFR CONDITIONS WILL DOMINATE CENTRAL NC TERMINALS FOR THE NEXT 24
HOURS. MOSTLY BKN MID LEVEL CLOUDS ASSOCIATED WITH A STRONG UPPER
LEVEL TROUGH MOVING THROUGH THE AREA WILL PERSIST THROUGH THE REST
OF THE OVERNIGHT HOURS THIS MORNING, AND A CLUSTER OF LIGHT SNOW
SHOWERS NOW MOVING THROUGH CENTRAL NC MAY BRING BRIEF LOWER CLOUDS
(MOSTLY SCT) BASED AT 2000-3000 FT AGL TO RDU/RWI/FAY 06Z-10Z. FAIR
SKIES WITH GENERALLY SCT MID-LEVEL CLOUDS AT 8000-15000 FT AGL ARE
EXPECTED THROUGH THE DAY. SURFACE WINDS WILL BE FROM THE WNW OR W AT
12-16 KTS WITH FREQUENT GUSTS UP TO 20-28 KTS FOR MUCH OF THE DAY,
UNTIL AROUND 22Z. A MID-LEVEL CIG IS POSSIBLE LATE IN THE PERIOD
(AFTER 02Z) AT GSO/RDU/RWI. THERE IS A GOOD CHANCE FOR LOW LEVEL
WIND SHEAR CONDITIONS AFTER 02Z AS WELL, WITH SURFACE WINDS FROM THE
SW UNDER 10 KTS AND WINDS JUST ALOFT FROM THE SW AT 35-40 KTS.
LOOKING BEYOND 06Z WED, LLWS WILL REMAIN POSSIBLE UNTIL AROUND 12Z.
OTHERWISE, VFR CONDITIONS WILL PREVAIL AT ALL SITES THROUGH SAT.-GIH
FIRE WEATHER
AS OF 945 PM MONDAY...
* AN INCREASED FIRE DANGER STATEMENT HAS BEEN ISSUED FOR TUESDAY FOR
CENTRAL AND EASTERN PORTIONS OF NC
ALTHOUGH RECENT RAINFALL HAS IMPROVED SOIL MOISTURE, ABNORMALLY DRY
CONDITIONS PERSIST ACROSS THE REGION. AFTER COORDINATION WITH THE
NCFS, IT HAS BEEN DETERMINED THAT A COMBINATION OF LOW RELATIVE
HUMIDITY LEVELS OF 25 TO 30 PERCENT AND WITH FREQUENT WESTERLY GUSTS
OF 20 TO 30 MPH WILL LEAD TO ELEVATED FIRE DANGER AND AN INCREASED
RISK OF ADVERSE FIRE BEHAVIOR.
