Hurricane Force Wind Warning 1, NWS Gray, ME

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE GRAY ME
1156 PM EST MON JAN 26 2015

.SYNOPSIS...
LOW PRESSURE WILL BEGIN TO DEVELOP OFF THE MID ATLANTIC COAST
TODAY THEN RAPIDLY INTENSIFY AS IT MOVES NORTHEASTWARD TO JUST
SOUTH OF NANTUCKET MASSACHUSETTS ON TUESDAY. THE LOW WILL LINGER
AROUND THROUGH WEDNESDAY BRINGING A SIGNIFICANT SNOWFALL TO OUR
REGION. THERE IS ALSO THE POTENTIAL FOR ANOTHER STORM LATE WEEK OR
EARLY IN THE WEEKEND BUT CONFIDENCE IS LOW AT THIS TIME.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
UPDATE...TOP DOWN SATURATION IS SLOWLY TRYING TO GET MORE
WIDESPREAD SNWFL INTO THE FORECAST AREA AT THIS HOUR. 00Z GYX
SOUNDING SHOWS PRONOUNCED DRY LAYER AT H8...WHICH SHOULD BE ERASED
IN THE NEXT COUPLE OF HOURS FOR COASTAL ME. ADJUSTED POP TO
REFLECT A SLIGHT DELAY...BUT QUICKLY NWD EXPANDING PCPN SHIELD.

ALSO THINKING AHEAD TO THE LARGER PART OF THE FORECAST TO COME IN
THE NEXT SEVERAL HOURS. 00Z RAOB OBJECTIVE ANALYSIS SHOWS 27.00Z CMC-
REGIONAL AND GFS VERIFYING BETTER THAN 26.12Z ECMWF FOR H5 HEIGHTS
INVOF DEVELOPING UPPER LOW PRES. THIS IS IMPORTANT BECAUSE 00Z
MODELS HAVE SHIFTED E WITH HEAVIEST QPF. A DEEPER H5 SCENARIO LIKE
THE ECMWF WOULD ACT TO CAPTURE AND PULL SURFACE LOW PRES FARTHER
W...INCLUDING THE QPF. SO 00Z ECMWF SHOULD BE IMPORTANT IN
DETERMINING WHERE TO INTRODUCE SHARPER WRN CUT OFF TO SNWFL
TOTALS.

ORIGINAL DISCUSSION...
SNOW SHOWERS HAVE ALREADY BEGUN DUE TO OCEAN EFFECT AND INCREASED
MOISTURE. WARM AIR ADVECTION WILL INCREASE IN EARNEST TONIGHT AND
WE SHOULD HAVE SNOW SPREADING ACROSS SOUTHERN NH AND COASTAL MAINE
OVERNIGHT. IN FACT SEVERAL INCHES WILL BE POSSIBLE BY DAYBREAK IN
THESE LOCATIONS. TEMPERATURES TUMBLE IN THE NORTH TONIGHT AS COLD
AIR IS PULLED TOWARDS THE APPROACHING STORM.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/...
NEW NAM AND GFS ARE MORE PROGRESSIVE TODAY... HOWEVER THE
EUROPEAN... WHICH GENERALLY HANDLES WINTER STORMS VERY WELL... IS
IN GOOD AGREEMENT WITH THE CANADIAN WHICH INCREASES THE QPF AND
WIND FIELDS ACROSS THE OUR REGION. THE EUROPEAN GETS CAUGHT IN THE
UPPER LEVEL FLOW AS THE UPPER TROUGH TILTS NEGATIVELY AND NOT ONLY
STALLS BUT RETROGRADES SLIGHTLY TUESDAY AFTERNOON... MEANDERING
AROUND THE BENCHMARK... AND DEEPENING SLIGHTLY MORE THAN THE OTHER
MODELS AS IT DOES SO. NEEDLESS TO SAY THE WIND FIELDS REMAIN VERY
IMPRESSIVE.

CURRENTLY THE STORM IS LOCATED OFF THE DELMARVA PENINSULA AND IS
AROUND 998 MB. WINDS ARE LOOKING NORTHERLY FOR THE MAJORITY OF THE
EVENT NOW AS THE SYSTEM WRAPS UP AND IS PULLED CLOSER TO THE
COAST. MESOSCALE MODELS ARE ALSO SHOWING AN EYE FEATURE SIMILAR
TO A HURRICANE... WHICH ARE PROMINENT ON STRONG MID LATITUDE
CYCLONES. IN ADDITION THE MAIN BANDING FEATURE(S) SHOULD BE
ORIENTED SSW TO NNE... FROM NEAR PORTSMOUTH NH TO LEWISTON ME TO
HARMONY ME EVENTUALLY AS THEY ROTATES ONSHORE. DUE TO THE ABOVE
MODEL CHANGES AND THE BANDING FEATURES MENTIONED... SNOWFALL
TOTALS WERE BUMPED UP SLIGHTLY. OTHERWISE NO WHOLESALE CHANGES...
AND HEADLINES REMAIN THE SAME EXCEPT FOR UPGRADING THE COASTAL
STORM WATCHES TO WARNINGS.

K INDICES INCREASE TO NEAR 20 ALONG CAPE COD AND DOWNEAST
INDICATING THE POSSIBILITY OF THUNDERSNOW LATE TUESDAY NIGHT.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
LOW PRESSURE WILL SLOWLY MOVE EAST AND OUT TO SEA WEDNESDAY. THE
EXIT SPEED WILL BE MODEL DETERMINANT...HOWEVER THE EURO IS THE
LEAST PROGRESSIVE AND STALLS OVER NANTUCKET BEFORE SLOWLY MOVE
THROUGH THE GULF OF MAINE.

HIGH PRESSURE WILL FOLLOW. ON FRIDAY...CYCLOGENESIS OCCURS ONCE
AGAIN OVER THE NEW ENGLAND WATERS. THE EURO SOLUTION REMAINS VERY
INTERESTING...WITH LOW PRESSURE RAPIDLY DEEPENING IN THE GULF OF
MAINE. THIS COULD BE AN INTERESTING EVENT AS WELL IF THE SYSTEM
CUTS OFF SOON ENOUGH TO OUR SOUTH.

VERY COLD ARCTIC AIR POURS IN FOR THE WEEKEND WITH SOME OF THE
COLDEST TEMPERATURES OF THE YEAR.

&&

.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
SHORT TERM...VFR CONDITIONS WILL DETERIORATE QUICKLY TONIGHT TO
MVFR AS CLOUDS LOWER AND THICKEN IN INCREASING LOW LEVEL MOISTURE.
SNOW AFFECTING CEILINGS AND VISIBILITIES AS FAR NORTH AS A KLEB
TO KAUG LINE ARE LIKELY BY 12Z...CREATING LIFR OR LOWER
CONDITIONS. ALL TERMINALS WILL DROP TO THESE LEVELS TUESDAY
THROUGH WEDNESDAY MORNING WITH THE LIKELY EXCEPTION OF WHITEFIELD.

LONG TERM...
CONDITIONS WILL GRADUALLY BE IMPROVING WEDNESDAY. LOCALLY...IFR
CONDITIONS RETURNING FRIDAY IN ANOTHER COASTAL LOW.

&&

.MARINE...
SHORT TERM...STORM WARNINGS REMAIN IN EFFECT THROUGH TUESDAY WITH
VERY STRONG WINDS AND SEAS AS HIGH AS 25'.

LONG TERM...
WINDS AND WINDS WILL GRADUALLY SUBSIDE WEDNESDAY. GALE FORCE WINDS
MAY RETURN LATE FRIDAY NIGHT INTO SATURDAY.

&&

.TIDES/COASTAL FLOODING...
LARGE...BATTERING WAVES WILL BE BUILDING LATE TONIGHT RIGHT AROUND
HIGH TIDE. THIS IN COMBINATION WITH A TWO FOOT STORM SURGE WILL
ALLOW PORTLAND AND HAMPTON TO REACH THEIR FLOOD STAGE. WINDS WILL
SWITCH TO THE NORTH TOMORROW AFTERNOON JUST PRIOR TO HIGH
TIDE...WHICH MAY REDUCE THE STORM SURGE. THIS IS VERY MODEL
DEPENDENT HOWEVER WITH THE EURO DANGEROUSLY BACKING IN THE STORM
TO NANTUCKET ISLAND.

USED THE NORTH ATLANTIC REGIONAL TEAM WAVE RUNUP MATRICES TO
FORECAST AND WARN FOR THE TWO TUESDAY HIGH TIDES. THE OUTPUT SHOWS
WAVE ACTION WILL ALLOW FOR LOCALLY SIGNIFICANT EROSION AS WELL AS
OVERWASH AT FORTUNES ROCKS...JENNIS...CAMP ELLIS AND FERRY BEACHES
IN MAINE AND NEW HAMPSHIRE.

NERACOOS SPLASH-OVER NOMOGRAMS ALSO SHOWING SIGNIFICANT ISSUES AT
THE TIME OF HIGH TIDE FOR THE BEACHES SOUTH OF PORTLAND.
