Severe Thunderstorm Warning 98, NWS Gray, ME

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME
936 AM EDT FRI AUG 21 2009

.SYNOPSIS...
A SLOW MOVING COLD FRONT WILL APPROACH THE REGION FROM THE WEST
THROUGH SATURDAY. A WARM HUMID FLOW OF AIR IN ADVANCE OF THE FRONT
WILL RESULT IN WIDESPREAD SHOWER AND THUNDERSTORM ACTIVITY ACROSS
THE REGION. SOME THUNDERSTORMS LATER TODAY AND THIS EVENING COULD
PRODUCE VERY GUSTY WINDS AND TORRENTIAL RAIN. HURRICANE BILL WILL
LIKELY PASS SOUTH AND EAST OF NEW ENGLAND LATE SATURDAY NIGHT AND
EARLY SUNDAY (SEE LATEST TRACK AND DETAILS FROM THE TROPICAL
PREDICTION CENTER). A WEAK DISTURBANCE WILL CROSS THE NORTHEAST ON
MONDAY. MUCH DRIER AIR WILL ENTER THE REGION DUE TO HIGH PRESSURE
ON TUESDAY AND WEDNESDAY. A STRONG COLD FRONT WILL BRING COOLER
AIR TO THE REGION LATE IN THE WEEK.

&&

.NEAR TERM /UNTIL 8 PM THIS EVENING/...
THE WARM FRONT WAS SITUATED THROUGH NORTHERN SECTIONS OF THE
FORECAST AREA AS OF 13Z...WITH DEWPOINTS QUICKLY RISING TO AT OR
ABOVE 70F FOLLOWING THE FROPA. GIVEN THE UPPER FLOW...THE LOWEST POTENTIAL
FOR STRONG CONVECTION WILL BE FOUND ACROSS EASTERN HALF OF THE AREA
WHERE STRONG MARINE INFLUENCE MAY DAMPEN ACTIVITY. KGYX VAD WINDS
SHOW SSW FLOW JUST ABOVE THE SURFACE...SO MUCH OF THE COAST WEST
OF WISCASSET /KIWI/ MAY BREAKOUT OF THE LOW CLOUDS AND FOG FEW
SEVERAL HOURS THIS AFTERNOON. MODIFIED 12Z RAOBS FROM KALB AND
KGYX SUPPORT STRONG CONVECTION...ESPECIALLY OVER WESTERN AND
NORTHERN SECTIONS WHERE PROSPECT FOR SEVERAL HOURS OF STRONG
HEATING EXISTS. WIND WILL BE BIGGEST ISSUE...WITH MARGINAL SVR
HAIL POSSIBLE IN THE STRONGEST CELLS. ALL 1ST PERIOD GRIDS WERE
ADJUSTED BASED ON SATELLITE/RADAR TRENDS AND MESONET.

PREV DISC...
WARM FRONTAL BOUNDARY CURRENTLY LOCATED OVER SOUTHERN NEW
HAMPSHIRE AND IT WILL CONTINUE TO LIFT NORTHWARD TODAY. DEWPOINTS
MOSTLY IN THE LOWER 60S NORTH OF THE BOUNDARY WILL INCREASE TO
AROUND 70 AFTER THE FRONT MOVES THROUGH...SO NOTICEABLY MORE
UNCOMFORTABLE THAN YESTERDAY. SPC HAS PLACE NEW HAMPSHIRE AS WELL
AS WESTERN MAINE IN SLIGHT RISK AREA TODAY AND HAVE GONE WITH
ENHANCED WORDING FOR THOSE AREAS FOR THIS AFTERNOON AND THIS
EVENING. HIGH PWATS IN TROPICAL AIR MASS SO ANY CONVECTIVE
ACTIVITY COULD PRODUCE SUBSTANTIAL AMOUNT OF RAINFALL IN SHORT
PERIOD OF TIME. ANTECEDENT CONDITIONS RELATIVELY DRY...SO NOT
LOOKING FOR SIGNIFICANT PRECIP PROBLEMS AT THIS TIME. USED BLEND
OF MAV/MET/CURRENT FORECAST FOR WINDS/TEMPERATURES AND BLEND OF
MAV/CURRENT FORECAST FOR POPS.

&&

.SHORT TERM /8 PM THIS EVENING THROUGH 6 AM SATURDAY/...
SHOWERS AND THUNDERSTORMS EXPECTED TO CONTINUE OVERNIGHT ALONG
WITH HUMID AIR MASS CONTINUING...SO LOOK FOR CONTINUING MUGGY
CONDITIONS WITH SOME DEGREE OF FOG.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
ALL EYES SHIFT TO THE PASSAGE OF HURRICANE BILL TO THE SOUTH AND
EAST OF NEW ENGLAND LATE SATURDAY NIGHT AND EARLY SUNDAY (SEE
LATEST OFFICIAL TRACK GUIDANCE FROM THE TROPICAL PREDICTION
CENTER). CURRENTLY...IT APPEARS THE MAIN THREAT FROM THIS STORM
WILL BE THE BUILDING WAVES AND SPLASH-OVER/BEACH EROSION NEAR THE
TIME OF THE HIGH TIDES OVER THE WEEKEND (SEE DETAILS IN THE
TIDES/COASTAL FLOODING SECTION BELOW). RIP TIDES MAY ALSO BE
PROBLEMATIC DUE TO BUILDING WAVES AND MANY SWIMMERS IN THE WATER
THIS TIME OF THE YEAR WITH THE UNUSUALLY WARM WATER TEMPERATURES.

CYCLONE PHASE DIAGRAMS AND NUMERICAL GUIDANCE DIFFER ON THE RATE
OF EXTRA-TROPICAL TRANSITION FROM MODEL TO MODEL. THIS WILL HAVE
SOME RAMIFICATIONS AS TO WHETHER BANDS OF RAIN CAN ROTATE WESTWARD
AROUND THE PERIPHERY OF BILL TO REACH OUR COASTLINE OR NOT (IE
SHIFT IN SOME OF THE PRECIPITATION TO THE LEFT OF TRACK AND
EXPANSION OF THE WIND FIELD). IN ANY CASE...THERE MAY BE A BOUNDARY
NEAR THE COAST WITH A SECOND OLD FRONTAL BOUNDARY OVER WESTERN
PORTIONS OF THE FORECAST AREA TO FOCUS PRECIPITATION LATER
SATURDAY...SATURDAY NIGHT AND EARLY SUNDAY. WITH PRECIPITABLE
WATER VALUES THROUGH THE ROOF (NEAR OR OVER TWO INCHES)...SOME OF
THE SHOWERS MAY PRODUCE LOCALLY VERY HEAVY DOWNPOURS. WILL NEED TO
MONITOR FIRST ROUND OF PRECIPITATION TODAY BEFORE GOING WITH ANY
FLOOD WATCHES FOR SATURDAY INTO EARLY SUNDAY. ANTECEDENT
CONDITIONS ARE VERY DRY...AND THE GROUND WILL NEED SOME PRIMING
FIRST BEFORE RIVERS AND STREAMS BEGIN TO RESPOND.

IN ANY CASE...WILL HAVE TO MONITOR DYNAMICAL JET STRUCTURE TO SEE IF WE
ARE IN A TYPICAL PRE PATTERN. THAT IS...WILL WE GET SIGNIFICANT
HEAVY RAINFALL OVER WESTERN PORTIONS OF THE FORECAST AREA?

WIND FIELDS MATCH UP RELATIVELY WELL WITH ADJACENT OFFICES FOR
THE WEEKEND AT THIS POINT.

REST OF FORECAST AFTER SUNDAY IS RELATIVELY DRY. MUCH COOLER AIR
IS POSSIBLE DURING THE LATE WEEK PERIOD.

&&

.AVIATION /13Z FRIDAY THROUGH TUESDAY/...
SHORT TERM...IFR/LIFR CONDITIONS THIS MORNING IN FOG WILL IMPROVE
TO MVFR CONDITIONS IN FOG/HAZE...PERHAPS SOME LOCAL VFR CONDITIONS
INLAND LATER THIS MORNING INTO THIS AFTERNOON WITH SHOWER/THUNDERSTORMS
DEVELOPING THIS AFTERNOON INTO THIS EVENING. SOME THUNDERSTORMS
MAY CONTAIN HAIL AND GUSTY WINDS. CONDITIONS LOWERING TO IFR/LIFR
IN FOG TONIGHT WITH CONTINUING CHANCE OF SHOWERS/THUNDERSTORMS.

LONG TERM...PLENTY OF LOW CLOUDS AND FOG...AS WELL AS SHOWERS AND
STORMS OVER THE WEEKEND. MAINLY IFR OR LIFR CONDITIONS. CONDITIONS
BEGIN TO IMPROVED SUNDAY NIGHT.

&&

.MARINE...
SHORT TERM...CONDITIONS BELOW SCA CRITERIA TODAY...AND WILL
APPROACH SCA CRITERIA TONIGHT FOR SEAS AND POSSIBLY WIND GUSTS.
VISIBILITY LOWERING TO 1 NM OR LESS TODAY AND CONTINUING TONIGHT.

LONG TERM...MAY SEE GUSTY WINDS LATE SATURDAY NIGHT INTO SUNDAY
MORNING WITH THE PASSAGE OF BILL TO OUR EAST. NORMALLY THIS IS
NOT AN ISSUE...BUT WE HAVE A COASTLINE LOADED WITH RECREATIONAL
AND COMMERCIAL BOATERS AT THIS TIME. HARBORS ARE CHALK FULL AT
THIS TIME. WILL CONTINUE TO MONITOR TPCS TRACK.

&&

.TIDES/COASTAL FLOODING...
NERACOOS SPLASH-OVER NOMOGRAM INDICATING THE POSSIBILITY OF
SPLASH-OVER AND BEACH EROSION SUNDAY NEAR THE TIMES OF HIGH TIDE.
TIDES ON SATURDAY WILL NEED TO BE MONITORED AS WELL AS HIGH ENERGY
SWELLS APPROACH THE BEACHES.

ASTRONOMICAL TIDES WILL BE VERY HIGH ON SATURDAY AS BUILDING LONG
PERIOD SWELLS REACH THE COASTLINE. WAVE WATCH III BRINGS SWELLS
TO AROUND 5-6 TO THE SOUTHERN MAINE AND NEW HAMPSHIRE COASTLINE.
THIS WILL BE MARGINAL SPLASH-OVER SITUATION SATURDAY. WAVES AND
STORM SURGE THEN INCREASE ON SUNDAY. RIGHT NOW...THE MAXIMUM STORM
SURGE IS EXPECTED TO BE IN BETWEEN THE SUNDAY  2 AM AND THE
SUNDAY  2 PM HIGH TIDES WITH A STORM SURGE OF AROUND 1 FOOT.
BIGGEST WAVES FORECAST BY THE WNA MODEL TO REACH THE COAST DURING
THE SUNDAY AFTERNOON HIGH TIDE (WHICH SEAMS REASONABLE)...BRINGING A
PARTICULAR PROBLEM FOR SPLASH-OVER TO THAT HIGH TIDE. MAY ISSUE A
STATEMENT TO DISCUSS THIS POTENTIAL. STORM TAKES A PREFERRED
TRACK...FAR ENOUGH OFFSHORE (NOT TUCKED IN TOO CLOSE SOUTH OF CAPE
COD)...TO BRING SOME GOOD SIZED WAVES TO THE REGION.

GFS STORM SURGE GUIDANCE IS CONSERVATIVE FOR SATURDAY (WITH A ZERO
OR NEGATIVE SURGE)...AS WELL AS A CONSERVATIVE/BENIGN SURGE DURING
THE TIMES OF HIGH TIDE ON SUNDAY. EXPECT WATER LEVELS TO REMAIN
HIGH...AND ONCE AGAIN - - WITH HIGH ENERGY SWELLS REACHING THE
BEACHES...EXPECT THERE TO BE SPLASH-OVER AND STRONG RIP TIDES.

.GYX WATCHES/WARNINGS/ADVISORIES...
ME...NONE.
