DISCUSSION
AS OF 305 AM EDT THURSDAY...
KEY MESSAGE 1...CLEARING WITH PATCHY FOG EARLY THIS MORNING.
MAINLY DRY AND COOLER TO END THE WORK WEEK.
LATEST ANALYSIS REVEALS LOW PRESSURE JUST NORTH OF THE LOCAL
AREA EARLY THIS MORNING. THE ASSOCIATED SURFACE COLD FRONT IS
JUST WEST OF THE LOCAL AREA AND WILL BE CROSSING THE LOWER MID-
ATLANTIC THROUGH SUNRISE THIS MORNING. SOME LINGERING SHOWERS
ALONG THE COAST EARLY THIS MORNING THAT WILL TAPER OFF IN THE
NEXT FEW HOURS. A FEW RUMBLES OF THUNDER POSSIBLE ACROSS
NORTHEAST NORTH CAROLINA, BUT NO SEVERE THREAT TO SPEAK OF AT
THIS TIME. ALSO HAVE SOME PATCHY FOG EVIDENT IN REGIONAL OBS
THAT WILL PERSIST FOR A FEW MORE HOURS UNTIL THE DRIER AIR
ARRIVES IN EARNEST WITH THE FRONTAL PASSAGE. THE FRONT MAY
LINGER ALONG THE FAR SE COAST, ALLOWING FOR THE LOW CHANCE OF A
BRIEF SHOWER OR TWO ALONG THE NORTHERN OBX. OTHERWISE,
DECREASING CLOUDS, BREEZY, AND DRIER TODAY ACROSS THE REGION.
SEASONABLE TEMPS TODAY, MAINLY IN THE UPPER 60S TO LOWER 70S.
COOL AND DRY TONIGHT WITH LOWS IN THE UPPER 30S TO LOW 40S
INLAND, UPPER 40S TO LOW 50S SE COAST UNDER A PARTLY TO MOSTLY
CLEAR SKY. SOME INCREASING CLOUDS TOMORROW AHEAD OF THE NEXT
SYSTEM, BUT REMAINING DRY THROUGH SUNSET. HIGHS MAINLY IN THE
60S.
KEY MESSAGE 2...RAIN CHANCES RETURN FRIDAY NIGHT AND SATURDAY.
RAINFALL TOTALS WILL BE LIGHT OVER MUCH OF THE AREA, WITH
STEADIER RAINFALL LIKELY LIMITED TO SOUTHEAST VIRGINIA AND
NORTHEAST NORTH CAROLINA. TEMPERATURES HOVER NEAR OR JUST BELOW
SEASONAL AVERAGE SUNDAY, BEFORE MODERATING THROUGH THE MIDDLE OF
NEXT WEEK.
INCREASING CLOUDS FRIDAY AFTERNOON AND EVENING AHEAD OF A MID-
LEVEL SHORTWAVE DROPPING IN FROM THE OHIO VALLEY. THIS FEATURE
COULD BRING A BRIEF SHOWER OR TWO OVER THE NORTHERN HALF OF THE
AREA FRIDAY NIGHT, WHILE REMAINING (BRIEFLY) DRIER ACROSS THE
SOUTH. AS THAT FEATURE WASHES OUT LATE FRIDAY, OUR NEXT
WEATHER-MAKER APPROACHES THE REGION FOR LATE FRIDAY NIGHT INTO
SATURDAY. A SOUTHERN STREAM SHORTWAVE SLIDES ACROSS THE GULF
COAST FRIDAY NIGHT, WITH SURFACE LOW PRESSURE LIFTING NORTHEAST
ALONG A COASTAL FRONT DRAPED ALONG THE SOUTHEAST COAST. NAEFS
IVT CONTINUES TO MAXIMIZE (97-99TH PERCENTILE) ALONG A CORRIDOR
FROM THE FLORIDA PANHANDLE TO THE CAROLINA COAST, SUGGESTING
THE PLUME OF DEEPEST MOISTURE REMAINS SUPPRESSED TO OUR SOUTH.
STILL, A STEADY SLUG OF LIGHT (STRATIFORM) RAINFALL IS EXPECTED
TO OVERSPREAD NORTHEAST NC AND HAMPTON ROADS ON SATURDAY.
UNFORTUNATELY, FORECAST CONFIDENCE IS ALSO INCREASING THAT THE
COOL, STABLE AIRMASS NORTH OF THE LOW TRACK WILL LIMIT THE
NORTHWARD PROGRESS OF THE DEEPER MOISTURE PLUME. ACCORDINGLY,
THE LATEST 00Z/30 GEFS/EPS PROBABILITIES FOR 0.1" REMAIN IN THE
70-100% SE OF RIC METRO, BUT HAVE LOWERED TO 20-50% OVER THE NW
HALF OF THE AREA. PROBABILITIES FOR A MORE SIGNIFICANT 0.5+" OF
RAINFALL REMAINS AT 50-80% IN THE SOUTHEAST, AND 20% OR LESS NW
OF A LINE FROM SOUTH HILL TO RICHMOND AND SALISBURY. THIS WILL
BE A WELCOME RAINFALL FOR SOME, TO BE SURE, BUT NOT A DROUGHT-
BUSTER BY ANY MEANS.
RAIN ENDS FROM SW TO NE SATURDAY NIGHT INTO SUNDAY MORNING.
CLEARING OUT AND REMAINING DRY SUNDAY, AS COOL HIGH PRESSURE
BUILDS BACK OVER THE REGION. HIGHS IN THE 60S, LOWS IN THE UPPER
30S TO MID 40S. TEMPERATURES THEN LOOK TO MODERATE BACK TOWARD
THEN BACK ABOVE CLIMO NORMAL FROM MONDAY TOWARD MIDWEEK.
AVIATION /06Z THURSDAY THROUGH MONDAY/
AS OF 230 AM EDT THURSDAY ...
A COLD FRONT WILL PUSH ACROSS THE TERMINALS IN THE NEXT FEW
HOURS. A FEW SHOWERS LIKELY AT THE KECG TERMINAL THROUGH THE
NEXT 1-2 HOURS BEFORE TAPERING OFF. SOME SPOTTY GROUND FOG/LOW
STRATUS LIKELY THROUGH 08-10Z OR SO BEFORE DRIER AIR PUSHES INTO
THE REGION POST-FRONTAL. MAINLY CLEAR OUTSIDE OF SCT AFTN CUMULUS
TODAY. LIGHT WINDS BECOMING NW ~10 KT BEHIND THE FRONT LATER
THIS MORNING. A FEW GUSTS NEAR 18-20 KT ARE POSSIBLE LATE THIS
MORNING AND THIS AFTERNOON.
OUTLOOK: PREVAILING VFR CONDITIONS THURSDAY NIGHT LAST THROUGH
FRIDAY AFTERNOON. ANOTHER STORM SYSTEM APPROACHES THE AREA ON
SATURDAY, BRINGING THE POTENTIAL FOR STEADY LIGHT TO MODERATE
RAIN ADDITIONAL FLIGHT RESTRICTIONS SAT/SAT NIGHT, WITH BEST
CHANCES OF SUB-VFR CIGS/VSBY IN SE VA/NE NC. DRYING OUT SUNDAY,
WITH MAINLY VFR CONDITIONS THROUGH EARLY NEXT WEEK.
