Severe Thunderstorm Warning 102, NWS Newport/Morehead City, NC

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEWPORT/MOREHEAD CITY NC
1117 AM EDT MON JUN 16 2008

.SYNOPSIS...
A COLD FRONT WILL APPROACH FROM THE NORTHWEST LATE TODAY AND MOVE
ACROSS THE AREA ON TUESDAY. HIGH PRESSURE BUILDS IN FROM THE WEST
WEDNESDAY THROUGH FRIDAY THEN MOVES OFFSHORE SATURDAY. A COLD
FRONT WILL PUSH ACROSS THE AREA LATE SATURDAY THROUGH SUNDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
FLOW WILL BECOME MORE CYCLONIC WITH TIME TODAY SUGGESTING A LITTLE
BETTER POTENTIAL FOR SEA BREEZE/DIFFERENTIAL HEATING CONVECTION
THIS AFTERNOON THAN DEPICTED BY THE GFS. WILL PAINT A 20 POP
ACROSS AREAS WHERE THE USUAL SEA BREEZE MIGRATION OCCURS DURING
PEAK HEATING. LEE TROUGHING SUPPORTS MODEL IDEA OF WARMER
TEMPERATURES TODAY WITH WESTERLY FLOW HELPING TO CONTRIBUTE TO HIGHS
IN THE LOWER 90S. LATEST HYSPLIT KEEPS SMOKE PLUME MAINLY NORTH OF
RODANTHE WITH STRONGEST CONCENTRATIONS AROUND THE WILDFIRE.
THEREFORE WILL EXTEND THE DENSE SMOKE ADVISORY FOR THE FIRE AREA
UNTIL 21Z BUT WILL NOT EXTEND ACROSS THE OUTER BANKS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/...
THE FRONT WILL JUMP TO THE LEE TROUGH POSITION TO OUR WEST TONIGHT
WITH PROXIMITY TO FRONTAL BOUNDARY WARRANTING A SLIGHT CHANCE POP.
OVERNIGHT LOWS WILL BE IN THE LOWER TO MIDDLE 70S.

LOOKS LIKE A DECENT CHANCE FOR SCATTERED STRONG TO SEVERE
THUNDERSTORMS TUESDAY AS FRONT SAGS SOUTH ACROSS OUR REGION. SPC
HAS ALL OF EASTERN NC IN A SLIGHT RISK OF SEVERE. A SERIES OF JET
STREAKS PASSING BY TO THE NORTH WILL PROVIDE UPPER LEVEL
DIVERGENCE ABOVE THE MODERATELY UNSTABLE (-6/-8 LI) AND MOIST
AIRMASS (PW 1.50-1.75). ALTHOUGH MID LEVEL LAPSE RATES ARE
FORECAST TO BE WEAK (6C/KM) SHEAR AND CAPE (3000 J/KG) WILL BE
STRONG ENOUGH TO SUPPORT UPDRAFT ORGANIZATION. DAMAGING WINDS
APPEAR TO BE THE MAIN THREAT WITH LARGE HAIL ALSO POSSIBLE IN THE
STRONGEST STORMS. UNIDIRECTIONAL FLOW INDICATES THAT A LINEAR MODE
OF CONVECTION MOST LIKELY. HPC FORECASTING WIDESPREAD 0.25-0.50
QPF AMOUNTS WITH LOCALLY MUCH HIGHER AMOUNTS POSSIBLE. DEPENDING
DURATION OF SUNSHINE HIGHS SHOULD BE AROUND 90.

WILL BRING FRONT THROUGH TUESDAY EVENING WITH DRIER AND COOLER AIR
FILTERING INTO THE REGION WEDNESDAY. GENERALLY FOLLOWED A BLEND OF
THE GUIDANCE WITH LOWS IN THE LOWER TO MIDDLE 60S TUESDAY AND
WEDNESDAY NIGHTS AND HIGHS IN THE MID 80S WEDNESDAY.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
AN UNSEASONABLY DEEP UPPER TROUGH WILL EXTEND SOUTH ACROSS THE
EASTERN US FROM AN UPPER LOW OVER SOUTHERN CANADA/NE STATES
THROUGH A PERIOD. SEVERAL WEAK SHORTWAVES ARE LIKELY TO ROTATE
AROUND THE TROUGH ACROSS THE AREA BUT MOISTURE INFLOW WILL BE POOR.
WILL KEEP FORECAST DRY BUT WOULD NOT BE SURPRISED TO SEE AN
ENHANCEMENT OF DIURNAL CONVECTION IN THE CYCLONIC FLOW AND BELOW
NORMAL HEIGHT FIELD. GFS IS DEEPER THAN ECMWF WITH THIS FEATURE AND
WOULD INDICATE TEMPS HAVING A HARD TIME BREAKING 80. NO
ADJUSTMENT MADE TO TEMPS THOUGH AS THE ECMWF IS THE FAVORED
SOLUTION. ALSO NO CHANGES TO DAYS 5-7 WITH TIMING OF NEXT FRONT.
THE GFS HAD TOO MUCH FEEDBACK TO TRUST ITS MEDIUM RANGE SOLUTION.

&&

.AVIATION /15Z MONDAY THROUGH FRIDAY/...
VFR CONDITIONS CONTINUE OVER AREA TERMINALS THIS MORNING WITH VERY
LIGHT SW WINDS UNDER CLEAR SKIES. STILL LOOKING AT THE POSSIBILITY
OF SOME SCT AFTERNOON CONVECTION FORMING ALONG THE SEA BREEZE WHICH
COULD AFFECT THE SOUTHERN TERMINALS OF KOAJ AND KEWN. WILL CONTINUE
TO MENTION A CB CLOUD GROUP FOR EWN AND OAJ AFT 19Z...OTHERWISE
SCT CU DEVELOPMENT WILL OCCUR THIS AFTERNOON ACROSS REMAINING
TERMINALS. VFR TO CONTINUE TONIGHT THEN A COLD FRONT WILL PASS
THROUGH ON TUESDAY BRINGING SCATTERED THUNDERSTORM ACTIVITY.
FORECAST SOUNDINGS INDICATE SOME OF THE STORMS MAY HAVE STRONG GUSTY
WINDS TUESDAY AFTERNOON/EVENING. WINDS WILL START OUT SOUTHWEST
TUESDAY MORNING VEERING TO NORTHEAST TUESDAY NIGHT AS THE FRONT
DROPS THROUGH. THE REMAINDER OF THE WEEK WILL BE DRY WITH HIGH
PRESSURE BUILDING IN FROM THE WEST.

&&

.MARINE...
MINIMAL CHANGES TO CURRENT MARINE FORECAST MAINLY TO ADD MENTIION OF
SMOKE ACROSS FAR NORTHERN WATERS AS WELL AS THE NORTHERN PORTION OF
THE PAMLICO. ALSO BUMPED UP SEAS TO 3 FT NEAR DIAMOND BUOY OTHERWISE
NO OTHER CHANGES NEEDED. LIGHT SW WINDS CURRENTLY OVER THE WATERS
WITH SEAS MAINLY 1 TO 2 FT. WIND SPEEDS WILL INCREASE A BIT THIS
AFTERNOON AS GRADIENT TIGHTENS AHEAD OF NEXT FROMT. SOME SCATTERED
CONVECTION POSSIBLE THIS AFTERNOON ALONG THE COAST. SOUTHWEST WINDS
WILL CONTINUE TONIGHT THROUGH TUESDAY MORNING. THE NEXT FRONT WILL
DROP THROUGH FROM THE NORTH ON TUESDAY. WINDS WILL START OUT
SOUTHWEST IN THE MORNING...EVENTUALLY BECOMING NORTHEAST TUESDAY
NIGHT. WILL KEEP WINDS JUST UNDER SMALL CRAFT CRITERIA. THE REST OF
THE WEEK WILL FEATURE LIGHT WINDS AND SEAS AS A RIDGE OF HIGH
PRESSURE BUILDS IN FROM THE WEST.
