SYNOPSIS
RAIN SHOWERS POSSIBLE THROUGH EARLY THIS AFTERNOON. GUSTY WINDS
ALONG THE COAST TODAY, DUE TO ANOTHER LOW OFF THE COAST. DRY
WEATHER AND MODERATED TEMPERATURES RETURN FOR THE WEEKEND.
NEAR TERM /THROUGH TONIGHT/
AS OF 300 AM EST FRIDAY...
KEY MESSAGES:
- RAIN CHANCES TAPERING OFF THIS MORNING LEAVING THIS AFTERNOON AND
TONIGHT DRY.
- SEASONABLE TEMPERATURES RETURN BEHIND THE RAIN.
EARLY MORNING ANALYSIS SHOWS THE LOW PRESSURE HAS REFORMED SOUTH OF
THE AREA ALONG THE NC COAST. LIGHT TO MODERATE RAIN CONTINUES FOR
MOST OF THE REGION EAST OF I-85 AND I-95. RAINFALL AMOUNTS REMAIN
HIGHEST SOUTH OF I-64, WITH TOTALS BETWEEN 1-2" WITH LOCALLY HIGHER
AMOUNTS POSSIBLE. AS THE LOW PRESSURE SLIDES FURTHER AWAY FROM
SHORE, RAIN CHANCES FOR THE AREA WILL DECREASE. AFTER DAYBREAK, THE
MAJORITY OF THE AREA WILL ONLY HAVE A SLIGHT CHANCE OF RAIN, WHILE
SE VA/ NE NC HAVE A SLIGHTLY HIGHER RAIN CHANCE POSITIONED CLOSER TO
THE LOW UNTIL EARLY THIS AFTERNOON. SKIES WILL BEGIN TO CLEAR OUT
LATE THIS AFTERNOON AND TONIGHT. WINDS WILL BE GUSTY THROUGHOUT THE
DAY SHIFTING FROM THE N TO NW OVERNIGHT. TEMPERATURES WON'T RISE
MUCH TODAY AS CLOUD COVER LINGERS. HIGHS WILL BE IN THE MID 50
(TOWARDS THE COAST WILL REACH UPPER 50S). OVERNIGHT, LOWS WILL REACH
THE LOWER TO MID 40S ACROSS THE REGION.
SHORT TERM /SATURDAY THROUGH SUNDAY/
AS OF 300 AM EST FRIDAY...
KEY MESSAGES:
- HIGH PRESSURE RETURNS BRINGING A DRY WEEKEND AND SEASONABLE
TEMPERATURES.
THE LOW PRESSURE THAT BROUGHT THE RAIN WILL BE PUSHED OUT BY HIGH
PRESSURE. THIS WILL ALLOW FOR SUNNY SKIES ON SATURDAY AND MOST SUNNY
SKIES ON SUNDAY. SATURDAY TEMPS WILL REACH THE LOWER 60S AND THEN
COOL DOWN TO THE MID 30S. SUNDAY WILL BE SIMILAR WITH HIGHS IN THE
LOWER 60S, BUT SLIGHTLY WARMER OVERNIGHT TEMPS AS CLOUDS FORM
RESULTING IN THE LOWER TO MID 40S.
LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/
AS OF 300 AM EST FRIDAY...
KEY MESSAGES:
- DRY/MILD WEATHER IS EXPECTED TO BEGIN THE WEEK.
- FIRST IN A SERIES OF COLD FRONTS CROSS THE REGION TUESDAY, WITH A
FEW SHOWERS POSSIBLE.
- BETTER CHANCES FOR RAIN WITH THE SECOND, STRONGER COLD FRONT WEDNESDAY
INTO THURSDAY, WITH BREEZY AND COOLER CONDITIONS FOR LATE
NEXT WEEK.
SURFACE HIGH PRESSURE AND THE UPPER RIDGE AXIS BECOMES CENTERED OVER
THE SOUTHEAST COAST BEGIN THE WORK WEEK ON MONDAY.
MEANWHILE, THE NEXT WESTERN CONUS UPPER TROUGH LOOKS TO EJECT
NORTHEAST FROM N MX INTO THE SOUTHERN PLAINS LATE MONDAY, EVENTUALLY
TAKING ON A NEGATIVE TILT AS IT LIFTS ACROSS THE CENTRAL PLAINS ON
TUESDAY. LOCALLY, SOUTHERLY RETURN FLOW BRINGS WARMER TEMPERATURES
FOR MONDAY, WITH HIGHS IN THE UPPER 60S ALONG THE COAST AND LOWER
70S INLAND.
AS LOW PRESSURE CONTINUES TO DEEPEN OVER THE MID MS VALLEY ON
TUESDAY, A CROSSING NORTHERN STREAM SHORTWAVE WILL DROP A WEAK COLD
FRONT SOUTH ACROSS THE AREA ON TUESDAY, BRINGING AN INCREASE IN
CLOUDS AND A MODEST COOL DOWN BACK TOWARD CLIMO NORMAL VALUES. A FEW
SHOWERS IS ALSO POSSIBLE ACROSS (MAINLY) THE SOUTHERN HALF OF THE
AREA TUESDAY EVENING, AS THE FRONT LOOKS TO BECOME HUNG UP OVER THE
REGION. EITHER WAY, EXPECT ANOTHER MILD NIGHT, WITH MINIMAL COOL AIR
ADVECTION AND AS CLOUDS LINGER OVER THE AREA AHEAD OF THE OHIO
VALLEY SYSTEM.
MODELS CONTINUE TO COME INTO BETTER AGREEMENT WITH THEIR HANDLING OF
THE DEEPENING UPPER TROUGH BUILDING OVER THE EAST COAST FOR THE
LATTER HALF OF NEXT WEEK. THE UPPER LOW DEEPENS OVER THE OHIO VALLEY
DURING THE MIDDLE OF NEXT WEEK, WITH THE SFC LOW OCCLUDING OVER THE
OHIO VALLEY WEDNESDAY. LATEST MODELS THEN PUSH THE ASSOCIATED SFC
COLD FRONT ACROSS THE LOCAL AREA WEDNESDAY NIGHT INTO EARLY
THURSDAY. A FEW SHOWERS LOOK TO BE POSSIBLE AHEAD OF THE SYSTEM WED
AFTN, WITH BETTER CHANCES AS THE FRONT CROSSES WED NIGHT INTO THU.
REMAINING MILD WITH HIGHS IN THE 60S TO AROUND 70, LOWS IN THE U40S
TO M50S.
FOR THU AND BEYOND, GEPS/EPS HAVE TRENDED TOWARD THE GFS/GEFS IDEA
OF A BROADER/DEEPER UPPER TROUGH BUILDING EAST OVER THE NORTHEAST
CONUS FOR THE LATE WEEK PERIOD. THIS WOULD TREND THE FORECAST TOWARD
A COOLER SOLUTION FOR LATE NEXT WEEK INTO NEXT WEEKEND, WITH COOL
AND GUSTY W-NW WINDS PROMOTING QUICK DRYING, AS THE UPPER LOW SWINGS
INTO THE NORTHEAST THU INTO FRIDAY. LINGERED POPS INTO THU/THU AFTN
FOR NOW DUE TO MODEL TIMING/DISCONTINUITIES BEFORE TAPERING OFF THU
NIGHT. COOLER HIGHS IN THE UPPER 50S TO LOW 60S ON THU WITH HIGHS IN
THE 50S ON FRIDAY. EARLY MORNING LOWS IN THE UPPER 40S TO LOW 50S
EARLY THU MORNING, AND IN THE UPPER 30S TO LOW 40S FRI MORNING.
AVIATION /15Z FRIDAY THROUGH TUESDAY/
AS OF 600 AM EST FRIDAY...
