AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME
950 AM EDT TUE JUL 18 2006

.SHORT TERM /REST OF TODAY/...LOOKS LIKE A SVR WX DAY TAKING SHAPE
WITH MOST OF THE STABILITY INDICES VERY HIGH. SOME WEAK ELEVATED
CONVECTION MOVED ALONG THE CANADIAN BORDER EARLY TODAY. WITH THE
MORE IMPORTANT CONVECTION NOW FIRING NW OF BTV. WIND DAMAGE IS THE
PRIMARY RISK TODAY BUT LARGE HAIL IS ALSO POSSIBLE IN ANY
SUPERCELL DEVELOPMENT. WILL NOT ISSUE AN UPDATE TODAY AS PREVIOUS
FCST LOOKS ON TRACK.

WILL UPDATE THE COASTAL FCST TO UPGRADE TO SCA FOR SEAS WITH WINDS
GETTING TO SCA CRITERIA IN GUSTS.

&&

.PREV DISCUSSION...
 /ISSUED 310 AM EDT TUE JUL 18 2006/

SHORT TERM /TODAY THROUGH TONIGHT/...
MAIN CONCERN WILL BE THE SEVERE THUNDERSTORM POTENTIAL FOR TODAY.
SPC HAS THE ENTIRE REGION IN A SLIGHT RISK OF SEVERE WEATHER
TODAY. A STRONG COLD FRONT MOVE MOVE SOUTHEAST ACROSS THE FORECAST
AREA TODAY THEN SLOWLY MOVE OFFSHORE TONIGHT. VERY UNSTABLE
CONDITIONS AHEAD OF THE COLD FRONT. TEMPERATURES AND DEW POINTS IN
THE 60S TO AROUND 70 EARLY THIS MORNING AND TEMPERATURES SHOULD
WARM DURING THE MORNING TO THE 80S AND LOWER 90S FOR MOST AREAS
BEFORE THE CONVECTION DEVELOPS AND/OR ADVECTS INTO THE REGION.

AT THE 850 MILLIBAR LEVEL MOISTURE IS ABUNDANT WITH MODELS SHOWING
AN AXIS OF DEW POINTS AS HIGH AS PLUS 15 CELSIUS AND THETA-E
VALUES OF 340. LIFTED INDEXES WELL BELOW ZERO AND CAPE VALUES OF
2000 OR HIGHER. THE FRONT WILL PROVIDE LIFT ALONG WITH ANY OUTFLOW
BOUNDARIES FROM OLD CONVECTION. ENOUGH WIND AND WIND SHEAR TO
SUPPORT STRONG TO SEVERE CONVECTION POTENTIAL.

WILL USE ENHANCED WORDING IN ZONES...HEAVY RAIN...GUSTY WINDS AND
HAIL WITH ANY THUNDERSTORMS.

THERE IS SOME FOG AROUND AT THIS TIME AND WILL MENTION PATCHY
EARLY MORNING FOG TODAY.

FOR TONIGHT HIGH PRESSURE BUILDS IN FROM CANADA PROVIDING COOLER
AND LESS HUMID WEATHER. HOWEVER...WITH FRONT SLOWING DOWN OFFSHORE
THE CHANGE IN AIR MASS WILL BE SLOWER TO ARRIVE OVER MORE SOUTHERN
AND COASTAL REGIONS TONIGHT.

USED THE GFS40...HPC QUANTITATIVE PRECIPITATION FORECASTS...
WNAWAVE SEAS FORECAST AND MAV MOS GUIDANCE FOR THE SHORT TERM
FORECAST.

LONG TERM /WEDNESDAY THROUGH MONDAY/...
HIGH PRESSURE WILL BUILD EAST ACROSS THE REGION FOR BOTH WEDNESDAY
AND THURSDAY. NOTICEABLY LOWER DEW POINTS THROUGH WEDNESDAY NIGHT
THEN VALUES BEGIN TO CREEP UPWARD AGAIN ON THURSDAY AS WE GET INTO
A SOUTHERLY FLOW ON THE BACKSIDE OF THE HIGH AND IN ADVANCE OF THE
NEXT COLD FRONT. ANOTHER ROUND OF STRONG CONVECTION ON FRIDAY AS
THE COLD FRONT CROSSES THE REGION...THEN SURFACE RIDGE TO BRING
DRIER LESS HUMID WEATHER FOR SATURDAY AND AT LEAST PART OF SUNDAY
BEFORE NEXT SYSTEM APPROACHES THE REGION.

AVIATION...
VISUAL FLIGHT RULES CONDITIONS WILL PREVAIL AFTER ANY PATCHY EARLY
MORNING FOG BURNS OFF...EXCEPT CONDITIONS WILL LOWER WITH ANY
THUNDERSTORMS TODAY. THERE IS THE POTENTIAL FOR STRONG GUSTY
WINDS...HAIL AND HEAVY RAIN WITH VERY LOW VISIBILITY WITH ANY
THUNDERSTORMS TODAY.

MARINE...
SHORT TERM /TODAY THROUGH TONIGHT/...SOUTHWEST WINDS AND SEAS
WILL BE CLOSE TO SMALL CRAFT ADVISORY LEVELS TODAY...BUT WILL HOLD
OFF ON PUTTING UP AN ADVISORY. CONDITIONS LET UP TONIGHT AS WINDS
SHIFT WITH THE PASSAGE OF THE COLD FRONT AND HIGH PRESSURE
BUILDING IN FROM THE NORTHWEST WEAKENS THE PRESSURE GRADIENT.

LONG TERM /WEDNESDAY THROUGH SATURDAY/...
GENERALLY QUIET THROUGH THE PERIOD. HOWEVER...WINDS AND SEAS WILL
LIKELY APPROACH SMALL CRAFT ON FRIDAY AS COLD FRONT SWINGS
EASTWARD ACROSS THE AREA.
