AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
329 PM EDT WED SEP 9 2015

.SYNOPSIS...
A COLD FRONT WILL CROSS THE AREA TONIGHT THEN STALL ALONG THE
COAST THURSDAY INTO FRIDAY WHILE LOW PRESSURE MOVES ALONG THE
FRONT.
&&

.NEAR TERM /THROUGH THURSDAY/...
THE MODELS ARE IN GOOD AGREEMENT THROUGH THE NEAR TERM PERIOD OF
THE FORECAST. A COLD FRONT WILL EXTEND ACROSS NW MAINE AT THE
START OF THE PERIOD. SHOWERS AND TSTMS EXPECTED ACROSS MAINLY NRN
ME. TSTMS MAY CONTAIN GUSTY WNDS AND HEAVY RAIN. BY EARLY THURSDAY
MORNING THE FRONT WILL MOVE TO CENTRAL MAINE. THE TSTMS WITH HEAVY
PCPN WILL MOVE EAST INTO NEW BRUNSWICK. THE FRONT WILL MOVE INTO
THE COASTAL WATERS BY TOMORROW MORNING WHERE IT IS EXPECTED TO
REMAIN QUASI-STATIONARY ALONG THE DOWNEAST COAST TOMORROW AS A LOW
ALONG THE COAST OF VIRGINIA TOMORROW MORNING DEEPENS AND TRACKS
NORTHEAST ALONG THE FRONTAL BOUNDARY. BY THE END OF THE PERIOD
THIS LOW WILL TRACK NE TO THE COAST OF NEW JERSEY.

TO SMOOTH OUT MINOR DIFFERENCE IN THE MODELS USE A BLEND THE
GFS/ECMWF/NAM/GEM FOR MAX/MIN TEMP WND/POP/SKY. LOADED NAWAVE 4
FOR SEAS IN THE COASTAL WATERS. WIND GUST MIXING LAPSE RATE TOOL
HAD A GOOD HANDLE ON CURRENT WIND GUSTS USED IT FOR WIND GUSTS
GRID FORECAST. LOADED HPC GUIDANCE FOR QPF.
&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
THE CONCERN FOR THURSDAY NIGHT INTO FRIDAY WILL BE THE TRACK OF A
LOW PRESSURE SYSTEM ALONG THE STALLED COLD FRONT. AT THIS
POINT...THE LOW IS EXPECTED TO MEANDER FROM THE JERSEY COAST ON
THURSDAY EVENING TOWARDS A POINT SOUTH OF CAPE COD BY EARLY
FRIDAY.  AN UPPER LEVEL SHORTWAVE ASSOCIATED WITH THIS SURFACE
LOW WILL TEND TO TAKE A MORE NORTHEASTWARD PATH AS A BROAD UPPER
LEVEL TROUGH DIGS IN THE WESTERN GREAT LAKES ON FRIDAY. AT THIS
TIME...WILL BRING OVERRUNNING PRECIP INTO BANGOR AND THE DOWN EAST
REGION ON THURSDAY NIGHT AND CONTINUE INTO FRIDAY. ON
FRIDAY...WILL ASSIGN THE HIGHEST POPS TO THE DOWN EAST REGION
WHILE KEEPING THE SAINT JOHN VALLEY DRY. WHILE THIS LOW IS NOT
TROPICAL...THERE IS DEEP MOISTURE WITH HIGH PWS AND A DEEP WARM
CLOUD LAYER. SOME UPPER LEVEL INSTABILITY IS ALSO POSSIBLE. AS A
RESULT...RAINFALL AMOUNTS MAY REACH NEARLY 2 INCHES THURSDAY NIGHT
INTO FRIDAY FOR BANGOR AND DOWN EAST.

THERE WILL PROBABLY BE SOME CLEARING LATER FRIDAY...ESPECIALLY IN
THE WESTERN ZONES. THIS CLEARING WILL BE DUE TO A BUILDING HIGH
PRESSURE SYSTEM THAT IS EXPECTED TO PROVIDE FAIR WEATHER FRIDAY
NIGHT AND SATURDAY. FOG LOOKS LIKE A PRETTY LIKELY THREAT WITH THE
ANTECEDENT MOISTURE...CLEAR SKIES AND LIGHT WINDS.
&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
HIGH PRESSURE WILL MOVE INTO THE CANADIAN MARITIMES ON SUNDAY. IT
LOOKS LIKE A DRY DAY...BUT THE DEVELOPING EASTERLY FLOW WILL
PROBABLY INDUCE ADVECT LOW LEVEL MOISTURE AND SOME STRATOCUMULUS
FIELDS INTO THE AREA...ESPECIALLY BY LATER IN THE DAY. THE
EVOLUTION AND MOVEMENT OF A CLOSED UPPER LEVEL LOW IN THE OHIO
VALLEY WILL BE THE DETERMINING FACTOR FOR AREA WHETHER SUNDAY
NIGHT INTO MONDAY NIGHT. FOR NOW...WILL FAVOR A SOLUTION THAT
MOVES THIS SYSTEM TOWARDS THE AREA ON SUNDAY NIGHT AND EXITS THE
REGION MONDAY NIGHT. WILL INCREASE POPS SUNDAY NIGHT AND DECREASE
FOR TUESDAY. A COLD FRONT WILL CROSS TUESDAY AND INTRODUCE LOWER
HUMIDITY.
&&

.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
NEAR TERM: MVFR CONDITIONS FOR CAR...PQI...HUL AT THE START OF
THE PERIOD. FVE IFR IN FOG/SHOWERS/ISOLD TSTMS. CONDITIONS WILL
FALL AT CAR...PQI AS THE FRONT PUSHES INTO THE AREA EARLY EVENING
TO IFR IN SHWRS/ISOLD TSTMS. IFR CONDITIONS WILL REMAIN UNTIL
TOMORROW MORNING. VFR BGR AND BHB. THE FRONT WILL PUSH INTO THE
BGR AREA LATE THIS EVENING BRINGING CIGS TO IFR...WILL REMAIN
THROUGH THE OVERNIGHT INTO TOMORROW MORNING. A FOG BANK ALONG THE
DOWNEAST COAST WILL SETTLE BACK INTO BHB THIS EVENING BRINGS CIGS
BACK TO IFR AROUND 10 PM...WITH FOG SETTLING BACK IN AROUND
MIDNIGHT. CONDITIONS ALL SITES EXCEPT BHB WILL IMPROVE TO MVFR
NORTH TO SOUTH AS THE FRONT PUSHES INTO THE COASTAL WATERS. BHB
WILL REMAIN UNDER THE INFLUENCE OF THE FRONTAL BOUNDARY. AS THE
LOW BEGINS MOVING NORTH ALONG THE FRONTAL SYSTEM THE FRONT ALONG
THE COAST WILL BEGIN TO MOVE BACK NORTH...KEEPING THE COASTAL
AREAS OF MAINE IN LOW CEILINGS AND LIGHT PRECIP.

SHORT TERM: THE PERIOD BEGINS WITH VFR AT ALL SITES...BUT EXPECT
CONDITIONS TO BECOME MVFR TEMPO IFR IN MODERATE RAIN FOR SITES
SOUTH OF HUL BY LATER IN THE NIGHT. THE RAIN CONTINUES INTO FRIDAY
MORNING. BY LATER FRIDAY...EXPECT ALL SITES TO BECOME VFR. FOG IS
POSSIBLE LATER FRIDAY NIGHT. WHEN THIS FOG BURNS OFF...VFR IS
FORECAST FOR THE REMAINDER OF SATURDAY INTO SATURDAY NIGHT. MVFR
CIGS ARE LIKELY FOR SUNDAY AT ALL SITES. THIS CONTINUES INTO
MONDAY WITH A TEMPORARILY LOWER CONDITIONS IN SHOWERS.
&&

ARE FORECASTED TO SUBSIDE TO LESS THAN 25 KTS BY THEN HOWEVER SEAS
WILL REMAIN ABOVE 5 FT. A SMALL CRAFT FOR SEAS MAY BE REQUIRED
FROM 11 PM THROUGH AROUND 3 AM.
