AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON NC
736 PM EDT MON JUN 14 2010
.SYNOPSIS...
VERY HOT DAYTIME TEMPERATURES WILL PERSIST THROUGH TUESDAY OVER
THE EASTERN CAROLINAS AS AN UPPER RIDGE REMAINS ANCHORED OVER THE
REGION. THUNDERSTORM CHANCES WILL INCREASE TUESDAY AND WEDNESDAY
AS A WEAK FRONTAL BOUNDARY STALLS ACROSS THE AREA. THE BOUNDARY
WILL PERSIST THROUGH FRIDAY. BERMUDA HIGH PRESSURE WILL RETURN FOR
THE UPCOMING WEEKEND.
&&
.NEAR TERM /THROUGH TONIGHT/...
AS OF 3 PM MONDAY...HEAT ADVISORY CONTINUES WITH VALUES HOVERING
JUST NEAR CRITERIA IN ALMOST ALL AREAS. WILL CONTINUE ADVISORY
THROUGH 0000 UTC. THE REMAINDER OF THE FORECAST CONCERNS THE
POSSIBILITY OF CONVECTION. NOTHING AS OF YET ALTHOUGH THE CUMULUS
FIELD IS EXTENSIVE. WILL MAINTAIN SLIGHT CHANCE POPS THROUGH THE
EVENING ALTHOUGH FORCING IS LIMITED AND GENERALLY CONFINED TO
AREAS TO THE NORTHEAST WHERE A SUBTLE SHORTWAVE RESIDES. THE GFS
IS SHOWING DECENT COVERAGE BY 1200 UTC TUESDAY MORNING. A VERY
SUBTLE AREA OF 700MB FRONTOGENESIS SEEMS TO BE RESPONSIBLE FOR
THIS. THE NAM DOES NOT HAVE THIS OVER OUR AREA ALTHOUGH IT DOES
HAVE SOME ACTIVITY TO THE WEST. WILL SHOW A MINIMUM OF POPS AROUND
0600 UTC WITH A SLIGHT INCREASE TOWARD MORNING TO ADDRESS THIS
UNCERTAINTY. THE COOLER...RELATIVELY SPEAKING...MAV NUMBERS APPEAR
TO BE HANDLING THIS HEATWAVE BETTER AND OPTED FOR THESE FOR
OVERNIGHT LOWS.
&&
.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...
AS OF 3 PM MONDAY...MAY NEED TO ISSUE ANOTHER HEAT ADVISORY...THIS
TIME FOR ONLY OUR SC COUNTIES...ON TUESDAY AS UPPER RIDGE
MAINTAINS DOMINANCE OVER THE EASTERN CAROLINAS. RIDGE WILL BECOME
SUPPRESSED ON WEDNESDAY AS AN UPPER LEVEL DISTURBANCE PASSES WELL
TO THE NORTH...ALLOWING MAXIMUM TEMPERATURES TO STAY A COUPLE
DEGREES EITHER SIDE OF 90. FOR TUESDAY....MID 90S WILL BE MORE OF
THE RULE. IT WILL CONTINUE TO BE UNCOMFORTABLY HUMID WITH DEW
POINTS IN THE 70S AND PRECIPITABLE WATER VALUES WILL INCREASE TO
OVER 2 INCHES BY TUESDAY EVENING. BETTER CHANCES OF CONVECTION ON
TUESDAY THAN TODAY...BUT LARGE SCALE SUBSIDENCE UNDER THE UPPER
RIDGE WILL KEEP POPS IN THE CHANCE CATEGORY AND WITH A CONVECTIVE
TEMPERATURE OF AROUND 95 DEGREES IT WILL TAKE A WHILE TO GET
THINGS GOING. CONVECTION IN THE AFTERNOON WILL IN ADDITION BE
AIDED BY A WEAK FRONTAL BOUNDARY...ONE HESITATES TO CALL IT A COLD
FRONT...AS IT DROPS OVER THE CAPE FEAR REGION. BETTER CHANCES OF
CONVECTION ON WEDNESDAY AS THIS BOUNDARY WILL REMAIN DRAPED
ACROSS THE AREA...SERVING AS A FOCUS FOR ACTIVITY...AND AS THE
UPPER RIDGE BREAKS DOWN. THIS WILL ALLOW CONVECTION TO FIRE OFF
EARLIER IN THE DAY THAN TUESDAY.
&&
.LONG TERM /THURSDAY THROUGH SUNDAY/...
AS OF 3 PM MONDAY...LAST COUPLE GFS RUNS SHOW A SLIGHT BREAKDOWN
IN THE RIDGING ALOFT ALONG THE EAST COAST...AND EVEN DEVELOP A NW
UPPER FLOW FRIDAY INTO SATURDAY. THIS UPPER FLOW IS STILL QUITE
WEAK SO EVEN IF A BOUNDARY DOES CROSS THE AREA...WE CAN ONLY
EXPECT A SLIGHT CHANGE IN AIRMASS. BIGGEST CHANGE IN THE MODELS IS
THE AMOUNT OF MID AND UPPER-LEVEL DRYING...WHICH COULD
SUBSTANTIALLY LIMIT POPS. HAVE HELD ONTO A LOW CHANCE POP THURSDAY
AHEAD OF THE WEAK SFC FRONT...BUT AFTER THAT IT TRENDS MORE TOWARD
SLIGHT CHANCE BY DAY AND DRY BY NIGHT WITH THE LACK OF MID-LEVEL
MOISTURE. TEMPS SEVERAL DEGREES COOLER THAN WHAT WE ARE GETTING IN
THE EARLY PART OF THE WEEK...BUT WILL CONTINUE TO BE SLIGHTLY
ABOVE NORMAL WITH DAYTIME HIGHS IN THE 90S BEING COMMONPLACE
INLAND...AND LOWS BOTTOMING OUT AROUND 70...WITH SOME LOWER/MID
70S ALONG THE BEACHES.
&&
.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
AS OF 00Z...MODERATE CONFIDENCE FORECAST THROUGH THE VALID PERIOD
WITH SCATTERED CONVECTION AND FOG POTENTIAL BEING THE LIMITING
FACTORS.
FAIRLY WELL DEVELOPED LINE OF CONVECTION IS CURRENTLY MOVING SE INTO
THE CWA AND WILL LIKELY AFFECT ALL TERMINALS THROUGH THE NEXT FEW
HOURS. HAVE TRIED TO TIME THIS LINE IN THE TAFS...AND BELIEVE TS
WILL AFFECT LBT BY 00Z...MOVING SE INTO THE COASTAL TERMINALS BY
02Z. BIGGEST THREAT WITH THIS LINE WILL BE BRIEF STRONG WINDS AND
HEAVY RAIN REDUCING VSBYS. EXPECT A SHORT WINDOW OF TS...WITH A
PERIOD OF RAIN BEHIND THE LINE. ONCE THIS MOVES THROUGH CONDITIONS
SHOULD IMPROVE RAPIDLY TO VFR WITH ONLY SCT CIRRUS BEHIND THE
CONVECTION.
HAVE NOT INTRODUCED FOG TO ANY TERMINAL TONIGHT...BUT WILL UPDATE IF
NECESSARY AT 06Z ISSUANCE. WINDS SHOULD REMAIN PREDOMINATELY FROM
THE N/NW THROUGH THE OVERNIGHT. THIS SHOULD HELP KEEP THE COLUMN
RELATIVELY DRY AND LIMIT MUCH IN THE WAY OF FOG. HAVE MODERATE
CONFIDENCE IN THIS SINCE SIMILAR CONDITIONS OCCURRED LAST NIGHT. THE
CAVEAT TO THIS WILL BE HOW MUCH RAIN FALLS AT THE TERMINALS TO HELP
SATURATE THE LOWEST LEVELS. SHOULD HAVE A BETTER HANDLE ON THIS AT
06Z ISSUANCE. FOR NOW AM COMFORTABLE NOT INTRODUCING FOG THOUGH.
SIMILAR DAY ON TAP FOR TUESDAY WITH VFR THE RULE THROUGH THE DAY
WITH LIGHT WINDS FROM THE EAST AND SCATTERED CONVECTION DEVELOPING
IN THE AFTN/EVE. BEST CHANCE FOR CONVECTION TUESDAY WILL BE LBT/ILM
WHICH IS CLOSER TO A SURFACE BOUNDARY...BUT WILL FOCUS ON THIS MORE
SPECIFICALLY ONCE CONVECTION DIES OUT TONIGHT.
EXTENDED OUTLOOK...MEDIUM CONFIDENCE DIURNAL CONVECTION EACH DAY
THROUGH FRIDAY. VFR SATURDAY.
&&
.MARINE...
NEAR TERM /THROUGH TONIGHT/...
AS OF 3 PM MONDAY...SURFACE TROUGH REMAINS PINNED ALONG THE COAST
THIS AFTERNOON WITH A WEAK WESTERLY FLOW INLAND SANS THE SEABREEZE
AND SOUTHWEST FLOW ACROSS THE WATERS. THIS WILL CONTINUE THROUGH
THE OVERNIGHT HOURS IN A 10-15...CLOSER TO 10 KNOT RANGE.
SEAS...PRIMARILY COMPOSED OF WIND WAVES WILL CONTINUE IN THE 2-3
FOOT RANGE.
SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...
AS OF 3 PM MONDAY...WEAK AND ILL DEFINED PRESSURE PATTERN ON
TUESDAY WILL KEEP WINDS LIGHT AND SEAS IN THE 2 FT RANGE. WINDS
WILL PICK UP TO 10 TO 15 KTS FROM THE SW LATER ON
WEDNESDAY...BUILDING SEAS ABOUT A FOOT BY EVENING.
LONG TERM /THURSDAY THROUGH FRIDAY/...
AS OF 3 PM MONDAY...BENIGN MARINE CONDITIONS EXPECTED THRU THE
EXTENDED WITH WIND SPEEDS REMAINING BELOW 15 KT AND SEAS GENERALLY
2-3 FT. WILL START OUT WITH SW FLOW AHEAD OF A TROF OR WEAK FRONT
INLAND ON THURSDAY. MODEST NW FLOW ALOFT WILL BE SUFFICIENT TO
PUSH THE FRONT INTO THE COASTAL WATERS BUT NOT MUCH FARTHER THAN
THAT. EXPECT A SHORT-LIVED WIND SHIFT TO THE NORTH EARLY
FRIDAY...BUT QUICKLY COMING BACK AROUND TO A S/SE DIRECTION AS THE
SEABREEZE BECOMES A BIGGER PLAYER THAN ANY SYNOPTIC GRADIENT.
LIGHT SOUTHERLY FLOW WILL REMAIN ENTRENCHED ON SATURDAY.
