AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON NC
315 PM EDT MON JUN 22 2015
.SYNOPSIS...
HOT AND HUMID CONDITIONS WILL PERSIST THROUGH THE END OF THE WEEK
WITH ISOLATED SHOWERS AND THUNDERSTORMS PRIMARILY DURING EACH
AFTERNOON AND EVENING. SLIGHTLY COOLER TEMPERATURES ALONG WITH A
BETTER CHANCE OF SHOWERS AND THUNDERSTORMS WILL DEVELOP THIS WEEKEND.
&&
.NEAR TERM /THROUGH TONIGHT/...
AS OF 315 PM MONDAY...HOT WEATHER CONTINUES WITH WELL ABOVE NORMAL
TEMPERATURES COMBINING WITH HIGH HUMIDITY TO CREATE POTENTIALLY
DANGEROUS HEAT INDICES VALUES TODAY. A HEAT ADVISORY WILL REMAIN IN
EFFECT FOR ALL COUNTIES INTO THE EARLY EVENING. ACTUAL TEMPERATURES
WILL RANGE FROM THE LOWER 90S NEAR THE BEACHES TO AROUND 100 WELL
INLAND. 850 TEMPS WERE UP AROUND 19 TO 20C WITH A VERY WARM AND
HUMID AIR MASS IN PLACE. DEWPOINTS TEMPS WERE DOWN INTO THE MID TO
UPPER 60S INLAND AS DEEP MIXING OCCURRED WHILE THE SEA BREEZE HAS
BEEN PUSHING INLAND BRINGING DEWPOINT TEMPS INTO THE MID TO UPPER
70S. STORMS WERE DEVELOPING IN MOISTURE RICH AIR OVER GEORGETOWN TO
WILLIAMSBURG AREA WHERE ML CAPE VALUES WERE UP TO 3500 J/KG. OVERALL
EXPECT STORMS TO REMAIN ISOLATED IN NATURE AND FOCUSED ALONG THE SEA
BREEZE. STEERING FLOW WAS WEAK...BUT WITH A SW-W COMPONENT PUSHING
STORMS SLOWLY TOWARD THE COAST...BUT MAINLY REMAINING ALIGNED WITH
SEA BREEZE BOUNDARY AS IT PROGRESSES INLAND.
HOT AND HUMID WEATHER WILL CONTINUE THROUGH TONIGHT IN SOUTHERLY
FLOW AROUND HIGH PRESSURE OFFSHORE....KEEPING DEWPOINT TEMPS IN THE
UPPER 60S TO MID 70S. THE REMNANTS OF AN MCS MOVING DOWN IN W-NW
INTO THE APPALACHIANS THIS AFTN WILL CONTINUE MOVING TOWARD THE
COAST AND THIS MAY PROVIDE SOME CLOUDS INTO THE AREA OVERNIGHT AS IT
BRUSHES BY TO THE NORTH...BUT OTHERWISE EXPECT STORMS TO DISSIPATE
AS HEATING OF THE DAY CUTS OFF INTO THIS EVENING.
&&
.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...
AS OF 315 PM MONDAY...DURING THE SHORT TERM PERIOD THERE IS NO
RELIEF IN SITE TO THE CURRENT PROLONGED HEAT EVENT. HEAT INDICES
WILL ONCE AGAIN EXCEED 105F TUESDAY AND WEDNESDAY AFTERNOON. AS A
RESULT WILL ISSUE A NEW HEAT ADVISORY FOR TUESDAY...WITH ANOTHER
LIKELY ON WEDNESDAY. T1 NUMBERS SUPPORT HIGHS IN THE MID 90S ALONG
THE COAST TO AROUND 100 INLAND AND WITH DEWPOINTS IN THE 70S EACH
DAY. NOT MUCH RELIEF AT NIGHT WITH LOWS IN THE UPPER 70S. CAN/T RULE
OUT ISOLATED TO WIDELY SCATTERED SHOWERS OR TSTMS EACH DAY...MAINLY
TRIGGERED BY THE SEA BREEZE AND INLAND TROUGH.
&&
.LONG TERM /THURSDAY THROUGH MONDAY/...
AS OF 315 PM MONDAY...MID LEVEL PATTERN WILL UNDERGO A SIGNIFICANT
CHANGE DURING THE PERIOD...TRANSITIONING FROM 5H RIDGE TO IMPRESSIVE
5H TROUGH BY THE END OF THE PERIOD. RIDGE AND ASSOCIATED HEAT HOLD
ON THU AND FRI BUT THE TRANSITION TO TROUGHING BEGINS DURING THE
WEEKEND. ALTHOUGH HEIGHTS ALOFT WILL BE DROPPING SAT AND SUN THE LOW
LEVELS REMAIN ON THE WARM SIDE. PRESENCE OF DEEP MOISTURE WITHIN AN
INCREASINGLY UNSTABLE ENVIRONMENT WILL LEAD TO AN INCREASE IN
CONVECTIVE ACTIVITY DURING THE WEEKEND. ALTHOUGH DIURNAL HEATING
WILL ENHANCE DAYTIME CONVECTION THINK STORMS WILL CONTINUE OVERNIGHT
GIVEN FAVORABLE CONDITIONS ALOFT. THERE IS ALSO LIKELY TO BE
ENHANCEMENT FROM PASSING SHORTWAVES BUT TIMING THESE FEATURES A WEEK
IN ADVANCE IS RATHER DIFFICULT. TEMPERATURES THROUGH SUN WILL REMAIN
ABOVE CLIMO DESPITE THE COOLING TREND WITH THU/FRI ENDING UP WELL
ABOVE CLIMO.
COLD FRONT MOVES INTO THE AREA SUN NIGHT OR EARLY MON BEFORE
STALLING AND BECOMING WASHED OUT. ALTHOUGH THE FRONT FAILS TO PASS
CLEANLY MID LEVEL DRY AIR DOES SPREAD OVER THE AREA...ENDING MOST OF
THE PRECIP. MID LEVEL TROUGH AXIS REMAINS WEST OF THE AREA MON SO
ALTHOUGH DRIER AIR WILL BE IN PLACE THERE WILL BE LACK OF
SUBSIDENCE. THE WEAK SURFACE GRADIENT WILL ALLOW AN AFTERNOON SEA
BREEZE WHICH WILL RESULT IN AT LEAST SOME POTENTIAL FOR ISOLATED
DIURNAL CONVECTION. TEMPS MON AND MON NIGHT WILL BE NEAR TO JUST
ABOVE CLIMO.
&&
.AVIATION /18Z MONDAY THROUGH SATURDAY/...
AS OF 17Z...TERMINALS CONTINUE TO BE VFR THIS EARLY AFTERNOON.
EXPECT TYPICAL SUMMER WEATHER PATTERN WITH LIGHT SW-W WINDS...EXCEPT
BECOMING S-SSW AT THE COASTAL TERMINALS BY EARLY AFTERNOON AS THE SEA
BREEZE DEVELOPS AND MOVES INLAND. MOISTURE IS LACKING BUT GIVEN THE
INSTABILITY ISOLATED THUNDERSTORMS SHOULD DEVELOP ALONG THE SEA BREEZE
BOUNDARY AND ALONG THE PIEDMONT TROUGH INLAND. BEST TIME FRAME FOR VCTS
AT THE COASTAL TERMINALS WILL BE 18-21Z OR UNTIL THE SEA BREEZE BOUNDARY
MOVES FAR ENOUGH INLAND...AND INLAND TERMINALS 20-24Z. CONVECTION
DISSIPATES THIS EVENING WITH LIGHT SW WINDS CONTINUING THROUGH THE NIGHT.
VFR CONDITIONS WILL CONTINUE THROUGHOUT THE OVERNIGHT PERIOD AND THROUGH
23/18Z WITH DRY ATMOSPHERE DO NOT EXPECT VSBY TO DROP TO MVFR.
EXTENDED OUTLOOK...CHANCE OF SHOWERS/THUNDERSTORMS TUE-SAT WITH
MAINLY VFR.
&&
.MARINE... NEAR TERM /THROUGH TONIGHT/...
AS OF 315 PM MONDAY...LIGHT SOUTHWEST FLOW AROUND ATLANTIC HIGH
PRESSURE WILL CONTINUE THROUGH TONIGHT. GUSTIER WINDS THROUGH EARLY
THIS EVENING WILL SUBSIDE THROUGH THIS EVENING BUT A DECENT PUSH OF
S-SW WINDS KEEP SEAS BETWEEN 2 AND 4 FT THROUGH THE NIGHT.
SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...
AS OF 315 PM MONDAY...THE SEABREEZE WILL ENHANCE THE WINDS ACROSS
THE COASTAL WATERS EACH AFTERNOON IN ADDITION TO A TIGHTENING OF THE
SOUTHWESTERLY PRESSURE GRADIENT BETWEEN THE INLAND TROUGH AND HIGH
PRESSURE OFF THE SOUTHEAST COAST. SPEEDS WILL BE IN THE 15-20 KT
RANGE TOMORROW THEN AROUND 15 KT ON WEDNESDAY BY THE AFTERNOON.
CHOPPY SEAS ARE EXPECTED AS A RESULT OF THE INCREASE IN WIND SPEEDS.
LONG TERM /THURSDAY THROUGH SATURDAY/...
AS OF 315 PM MONDAY...ALTHOUGH THE MID LEVEL PATTERN WILL BE
CHANGING AT THE SURFACE BERMUDA HIGH AND PIEDMONT TROUGH COMBINATION
WILL MAINTAIN SOUTHWEST FLOW OVER THE WATERS THROUGH SAT. GRADIENT
WILL TIGHTEN FROM TIME TO TIME AS TROUGH STRENGTHENS...MAINLY DURING
THE AFTERNOON AND EVENING HOURS. THIS WILL RESULT IN A SLIGHT BUMP
IN WIND SPEEDS EACH DAY. GENERALLY SOUTHWEST FLOW WILL BE 10 TO 15
KT WITH SEAS RUNNING 3 TO 5 FT.
