DISCUSSION
KEY MESSAGE 1: SEVERE STORMS POSSIBLE TODAY WITH DAMAGING WIND
GUSTS BEING THE PRIMARY THREAT.
AS THE MORNING WEARS ON, A POTENT COLD FRONT WILL STEADILY
APPROACH THE REGION, ENTIRELY RESHAPING THE DAY'S WEATHER. A
WARM, HUMID, AND HIGHLY UNSTABLE AIR MASS WILL SETTLE OVER THE
LANDSCAPE, CHARACTERIZED BY STEEP LAPSE RATES THAT WILL ACT AS
FUEL FOR ATMOSPHERIC TROUBLE. BY THIS AFTERNOON AND LASTING INTO
THE EARLY EVENING, THESE VOLATILE CONDITIONS WILL PROMOTE THE
DEVELOPMENT OF STRONG TO SEVERE STORMS, PLACING MOST OF THE AREA
UNDER A MARGINAL RISK FOR SEVERE WEATHER.
THE ENVIRONMENT WILL GROW EVEN MORE HOSTILE FURTHER TO THE
NORTHEAST. BEYOND A LINE STRETCHING FROM HOT SPRINGS TO
LYNCHBURG, CONVECTIVE AVAILABLE POTENTIAL ENERGY (CAPE) AND
VERTICAL WIND SHEAR WILL BE NOTABLY HIGHER. THIS POTENT
COMBINATION WILL SUPPORT A SLIGHT RISK ZONE, WHERE MORE
ORGANIZED AND LONGER-LIVED SEVERE THUNDERSTORMS ARE EXPECTED TO
FLOURISH. WHILE A VARIETY OF HAZARDOUS WEATHER IS POSSIBLE,
TODAY’S PRIMARY SEVERE THREAT WILL MANIFEST AS DAMAGING WINDS
CAPABLE OF DOWNING TREES AND POWER LINES AS THE LINE OF STORMS
MARCHES THROUGH.
KEY MESSAGE 2: THERE IS A FLASH FLOOD RISK TODAY.
THE RELENTLESS WET PATTERN IS ABOUT TO INTENSIFY. RAIN HAS
ALREADY BEEN PLENTIFUL OVER THE LAST SEVEN DAYS, BUT OVER THE
LAST COUPLE OF DAYS, THE AREAL COVERAGE OF 3 TO 5 INCH RAIN
RATES HAS BEEN STEADILY INCREASING. SOME AREAS ON EITHER SIDE OF
THE BLUE RIDGE SOUTH OF ROANOKE HAVE ALREADY BEEN PRIMED,
HAVING SWALLOWED TWO TO FOUR INCHES OF RAIN IN JUST THE PAST 48
HOURS.
WITH PRECIPITABLE WATER (PWAT) VALUES HOVERING IN THE 1.5 TO
2.0- INCH RANGE TODAY, THE ATMOSPHERE WILL REMAIN COMPLETELY
SATURATED. AS MORE ORGANIZED STORMS BEGIN TO FORM AND MOVE
THROUGH THIS AFTERNOON, THE CHANCES FOR FLASH FLOODING WILL
INCREASE ACROSS THE ENTIRE AREA. BECAUSE THE GROUND IS ALREADY
WET, THE REGION WILL SIT UNDER A MARGINAL RISK FOR EXCESSIVE
RAINFALL, MEANING ANY HEAVY DOWNPOUR COULD QUICKLY TRANSLATE
INTO RAPID RUNOFF AND LOCALIZED FLOODING.
AVIATION /07Z WEDNESDAY THROUGH SUNDAY/
THE EARLY MORNING HOURS WILL BRING A MURKY START FOR ANY AREAS
CATCHING A BRIEF BREAK IN THE RAIN, AS THEY WILL EXPERIENCE A
BLANKET OF IFR TO LIFR LOW CLOUDS AND DENSE FOG. HOWEVER,
ANOTHER BAND OF RAIN CURRENTLY MOVING IN ACROSS THE MOUNTAINS
WILL ACTUALLY HELP STIR THE ATMOSPHERE, LIKELY LIFTING
RESTRICTIONS TO MVFR OR VFR LEVELS. WHILE VISIBILITIES WILL
STEADILY IMPROVE BY MID-MORNING, THE STUBBORN LOW CLOUDS MAY
STILL HANG AROUND WELL INTO THE EARLY AFTERNOON.
THE BRIEF LULL WILL NOT LAST LONG. AS A POTENT COLD FRONT
APPROACHES THE AREA FROM THE NORTHWEST, THE CHANCES FOR
ORGANIZED, SCATTERED STORMS WILL INCREASE DRAMATICALLY ACROSS
THE ENTIRE REGION THIS AFTERNOON. THIS FRONT WILL FINALLY PUSH
THROUGH AND CLEAR THE AREA LATE TONIGHT, SWEEPING AWAY THE
MOISTURE AND BRINGING A MUCH-NEEDED RETURN OF DRY WEATHER TO THE
REGION BY TOMORROW MORNING.
EXTENDED AVIATION OUTLOOK...
BY THURSDAY, THE STALLED FRONT PUSHES SOUTH OF THE AREA, WITH
HIGH PRESSURE FROM THE NORTH MOVING IN. WHILE SHOWER/STORMS MAY
STILL BE POSSIBLE, THEY WILL BE ISOLATED AND PRIMARILY LIMITED
TO OUR SOUTHERN LOCATIONS, SUCH AS DAN. THIS WILL ALLOW FOR
MOSTLY VFR FLIGHT CONDITIONS TO RETURN TO THE REMAINDER OF THE
TERMINALS. VFR WILL BE EXPECTED TO CONTINUE, THOUGH FOG REMAINS
POSSIBLE DURING THE OVERNIGHT HOURS.
