DISCUSSION
AS OF 355 PM SUNDAY...
KEY MESSAGE 1... MUCH QUIETER WEATHER LATE THIS AFTERNOON AND
EVENING WITH A BRIEF SHOWER POSSIBLE.
THE TORNADO WATCH HAS BEEN CANCELLED FOR ALL OF CENTRAL NC AND THE
DEEP CONVECTION HAS EXITED THE AREA AS MID AND UPPER LAYER
DRYING IS SPREADING ACROSS THE AREA. A MOIST CYCLONIC FLOW
CONTINUES WITH SOME WEAK RESIDUAL INSTABILITY ACROSS THE EASTERN
PIEDMONT, SANDHILLS AND VA BORDER COUNTIES. A FEW SHOWERS MAY
DEVELOP IN THIS ENVIRONMENT OVER THE NEXT FEW HOURS BUT THE
COVERAGE SHOULD BE LIMITED. ALL OF THE SHOWERS SHOULD WIND DOWN
BY AROUND SUNSET WITH FAIR WEATHER EXPECTED OVERNIGHT.
KEY MESSAGE 2... NO SIGNIFICANT PRECIPITATION IS EXPECTED FOR MUCH
OF THE UPCOMING WEEK.
A NORTHWEST TO WESTERLY FLOW ALOFT WILL DOMINATE THE WEATHER PATTERN
THROUGH THE WORK WEEK SUPPORTING A GENERALLY FAIR AND DRY WEATHER
PATTERN. A BACK DOOR COLD FRONT TRIES TO DROP INTO THE REGION
ON THURSDAY BUT ENSEMBLES SUGGEST THE STRONG UPPER LEVEL RIDGE
WILL LIKELY RESTRAIN THE FRONT ACROSS WV AND VA. PRECIPITATION
WITH THIS FEATURE SHOULD BE LIMITED AND LIKELY NORTH OF THE
AREA. A STRONGER COLD FRONT WILL SWEEP SOUTHEAST ACROSS THE
REGION ON FRIDAY AND FRIDAY NIGHT, THIS SYSTEM WILL BE MOISTURE
STARVED AND LITTLE PRECIPITATION IS EXPECTED. THE GENERALLY DRY
WEST AND NORTHWESTERLY FLOW WILL UNFORTUNATELY KEEP THE AREA
PRECIPITATION FREE.
KEY MESSAGE 3... A BIG WARMUP IS EXPECTED FOR MID WEEK BEFORE A
SIGNIFICANT COOL DOWN BY THE WEEKEND WITH FROST POSSIBLE.
THE LARGE RIDGE DEVELOPING ACROSS THE DEEP SOUTH WILL ALLOW MORNING
LOW LEVEL THICKNESS VALUES TO RANGE FROM 1400 TO 1410M ON WEDNESDAY
MORNING. THIS WILL SUPPORT AFTERNOON HIGHS IN THE MID TO POSSIBLY
UPPER 80S WHICH ARE ABOUT 12 TO 17 DEGREES ABOVE AVERAGE.
A SIGNIFICANT COOL DOWN IS EXPECTED THIS WEEKEND WITH MORNING LOW
LEVEL THICKNESS VALUES BY SUNDAY MORNING RANGING IN THE 1310 TO
1320M RANGE. IT'S WORTH NOTING THAT THE OPERATION GFS IS
SHOWING ITS COLD BIAS WITH ITS FORECASTING LOW LEVEL
THICKNESSES ON SUNDAY MORNING FROM 1295 TO 1305M WITH THE GFS
MOS PROVIDING LOWS OF 33/35 AT ROXBORO AND RALEIGH! NOT READY TO
JUMP ON THAT DEGREE OF COLD BUT A CONSENSUS APPROACH SUPPORTS
LOWS INTO THE UPPER AND POSSIBLY MID 30S WHICH WOULD SUPPORT A
FROST RISK.
AVIATION /00Z MONDAY THROUGH FRIDAY/
AS OF 810 PM SUNDAY...
LOW PRESSURE WILL SHIFT TO OUR NE TONIGHT, THIS WILL ALLOW FOR
CLEARING SKIES. VFR CIGS IN STRATOCUMULUS WILL PERSIST THROUGH 06Z
AND THEN BREAK UP BETWEEN 06Z AND 09Z, AND RETURN AROUND DAYBREAK
THROUGH NOON. REGARDLESS, CIGS WILL BE VFR. WINDS WILL BE SW AT
GUSTY TO 20KT THROUGH MUCH OF THE NIGHT, THEN SHIFT TO THE NNW AT 10-
15KT FROM 12Z-15Z, DIMINISHING IN THE AFTERNOON.
OUTLOOK: GENERALLY VFR CONDITIONS ARE EXPECTED FOR MOST OF THE WORK
WEEK.
