AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME
835 PM EDT FRI JUL 4 2014
.SYNOPSIS...
HURRICANE ARTHUR WILL MOVE NORTHEASTWARD OFF THE MID ATLANTIC
COAST TODAY AND INTO THE CANADIAN MARITIMES LATE TONIGHT OR
SATURDAY MORNING. HEAVY RAIN WILL FALL ALONG THE COAST OVERNIGHT.
NORTHERLY WINDS WILL STRENGTHEN ON SATURDAY BEHIND THE STORM.
HIGH PRESSURE WILL MOVE SOUTH OF THE REGION ON SUNDAY. A SLOW MOVING
COLD FRONT WILL APPROACH FROM CANADA MONDAY NIGHT THROUGH WEDNESDAY
AS A SERIES OF WEAK LOWS TRAVEL ALONG THE BOUNDARY. THIS WILL RESULT
IN UNSETTLED WEATHER WITH A PROLONGED PERIOD OF SCATTERED SHOWERS
AND THUNDERSTORMS. THE FRONT WILL PUSH THROUGH ON THURSDAY PRODUCING
MORE SHOWERS AND THUNDERSTORMS. HIGH PRESSURE BRINGS WILL FINALLY
BRING FAIR WEATHER ON FRIDAY.
&&
.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
825 PM...ON THE WHOLE...FORECAST THINKING IS UNCHANGED WITH
HEAVIEST RAIN EXPECTED THROUGH ABOUT 04-06Z ACROSS THE WRN 2/3 OF
THE CWA...AND LINGERING HEAVY RAIN THRU 09-12Z OVER MID-COAST.
QPFS LOWERED A BIT IN THE NW ZONES. SHOULD SEE N-NW WINDS BEGIN TO
PICK UP AFTER MIDNIGHT...BUT STRONGEST WILL HOLD OFF UNTIL AFTER
SUNRISE.
PREVIOUSLY...HURRICANE ARTHUR CONTINUES TO MOVE UP THE NORTHEAST
COAST THIS AFTERNOON... AND SHOULD TRACK OFFSHORE OF CAPE COD THIS
EVENING. MEANWHILE... A COLD FRONT PUSHED ACROSS NEW HAMPSHIRE AND
HALF OF WESTERN MAINE BEFORE STALLING NEAR PORTLAND/LEWISTON. RAIN
CONTINUES TO SPREAD ACROSS NEW HAMPSHIRE AND WESTERN MAINE
ASSOCIATED WITH A DEFORMATION ZONE BETWEEN AIR BEING PULLED
NORTHEASTWARD ALONG THE FRONT AND SOUTHWARD INTO HURRICANE ARTHUR.
IN ADDITION... AN OUTER BAND FROM HURRICANE ARTHUR IS DRIFTING
NORTHWARD THROUGH THE SOUTHEAST NEW ENGLAND COAST AND THROUGH THE
GULF OF MAINE... WITH SCATTERED THUNDERSTORMS EMBEDDED IN THE
BAND. THIS IS WHERE THE HEAVIEST RAIN IS OCCURRING NOW AND IS
EXPECTED TO OCCUR OVERNIGHT. THIS BAND WILL LIKELY PUSH TO THE
NORTHWEST AND MAKE IT TO THE COAST OF MAINE THIS EVENING.
ARTHUR WILL MAKE A TURN TO THE NORTH AS IT PASSES TO OUR EAST...
TRACKING GENERALLY TOWARD NOVA SCOTIA. BUT THE TURN TO THE NORTH
WILL ALLOW THE OUTER BANDS TO AFFECT THE MIDCOAST REGION LONGER
WITH HEAVY RAIN CONTINUE UNTIL MORNING.
DO NOT EXPECT HIGH WINDS OR STORM SURGE WITH HURRICANE ARTHUR
ACROSS OUR FORECAST AREA. THE PRIMARY THREAT WILL BE THE HEAVY
RAIN. FLASH FLOOD WATCH CONTINUES UNTIL MORNING WHEN RAIN SHOULD
FINALLY COME TO AN END.
ONE CONCERN ABOUT HEAVY RAIN POTENTIAL IS MUCH LOWER DEW POINTS
BEING ADVECTED INTO THE AREA ON THE NORTHERLY WINDS BEHIND THE
FRONT AND ON THE NORTH SIDE OF ARTHUR (AS THE FRONT BEGINS TO
MERGE WITH ARTHUR). DEW POINTS WILL BE FALLING THROUGH THE 50S
TONIGHT IN SPITE OF THE RAIN... WITH TEMPERATURES FALLING ALONG
WITH THEM. THIS WILL LIMIT TOTAL RAINFALL POTENTIAL... BUT
BOUNDARY BETWEEN THE COOLER/DRIER AIR AND THE WARM/MOIST AIR WITH
ARTHUR WILL BE THE FOCUS FOR THE HEAVIEST RAINFALL. THUS THE FLASH
FLOOD WATCH CONTINUES FOR THE AREAS MOST LIKELY TO BE AFFECTED BY
THIS FEATURE.
&&
.SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/...
ARTHUR MOVES EAST ON SATURDAY WITH ANY LINGERING RAIN IN THE
MIDCOAST ENDING EARLY IN THE MORNING. THE STRONG PRESSURE GRADIENT
LEFT IN ITS WAKE WILL CAUSE GUSTY NORTHERLY WINDS DURING THE DAY.
GUSTS TO 30 MPH ARE POSSIBLE. EXPECT DRY CONDITIONS AND
TEMPERATURES TOPPING OUT MAINLY IN THE 70S.
WINDS SUBSIDE A BIT SATURDAY NIGHT AND TEMPERATURES FALL INTO THE
50S. MAY SEE A FEW 40S IN NORTHERN VALLEYS AS DRY AIR ALLOWS THE
LOW LEVELS TO RADIATE BETTER.
&&
.LONG TERM /SUNDAY THROUGH FRIDAY/...
HIGH PRESSURE MOVES S OF THE REGION ON SUNDAY. THE HIGH STAYS WELL
OUT TO SEA AS A SLOW MOVING COLD FNT APPROACHES FROM CANADA MONDAY
THRU WEDNESDAY. THE UPPER LVL FLOW IS CYCLONIC OVER THE ERN HALF OF
THE U.S. AND CANADA AS A SERIES OF SHORT WAVE TROFS MOVE THRU THIS
LONG WAVE TROF. THIS PRODUCES A SERIES OF WEAK LOWS THAT WILL TRAVEL
E NE ALONG THE SFC FNT AND KEEP IT FROM PUSHING THRU THE FCST AREA.
THE SW FLOW OF VERY WARM, MOIST AND UNSTABLE AIR WILL HELP GENERATE
SCT SHRA AND TSTMS AHEAD OF THE FNT AND WEAK LOWS. FINALLY THE LAST
AND ALSO THE STRONGEST SHORT WAVE TROF MOVES THRU ERN CANADA ON
THURSDAY DRIVING THE SFC FNT THRU THE FCST AREA. SCT SHRA AND TSTMS
WILL CONT THURSDAY WITH DRY WX FOLLOWING THE FNT FOR THURSDAY NGT.
HIGH PRESSURE BUILDS IN FROM THE W ON FRIDAY AS UPPER LVL HEIGHTS
RISE. THE HIGH WILL BRING FAIR, DRY AND LESS HUMID WX.
USED A BLEND OF VARIOUS MODELS...HPC GUIDANCE...PREVIOUS FCST FOR
PERSISTENCE AND CLIMATOLOGY FOR THE LONG TERM FCST.
&&
.AVIATION /01Z SATURDAY THROUGH WEDNESDAY/...
SHORT TERM...
MANY TERMINALS HAVE REMAINED VFR FOR MOST OF THE DAY IN SPITE OF
THE RAIN... BUT EXPECT COASTAL LOCATIONS TO DETERIORATE AS HEAVIER
BANDS FROM HURRICANE ARTHUR ARRIVE THIS EVENING. SHOULD SEE A
QUICK IMPROVEMENT TO VFR BY TOMORROW MORNING... BUT THERE WILL BE
NORTHWEST WINDS GUSTING TO ABOUT 25 OR 30 KT.
LONG TERM /SUNDAY THROUGH WEDNESDAY/...VFR SUNDAY. UNSETTLED WX
WITH SCT SHRA/TSTMS MONDAY THRU WEDNESDAY PRODUCING MVFR/IFR
CONDITIONS AT TIMES.
&&
.MARINE...
SHORT TERM...
HURRICANE ARTHUR WILL PASS TO THE EAST... AND NORTHERLY FLOW
AROUND THE SYSTEM WILL INCREASE TO GALE STRENGTH ACROSS MUCH OF
THE GULF OF MAINE. GALES SHOULD SUBSIDE ON SATURDAY WITH WAVE
HEIGHTS STAYING HIGH THROUGH SATURDAY NIGHT.
LONG TERM /SUNDAY THROUGH WEDNESDAY/...PROLONGED SW FLOW AHEAD OF
A SLOW MOVING CANADIAN FNT WILL LIKELY PRODUCE SCA CONDITIONS OVER
THE OPEN WATERS...WIND GUSTS AND SEAS...DEVELOPING SUNDAY AND
CONTINUING THRU TUESDAY. THE PRESSURE GRADIENT LETS UP TUESDAY NGT
AND WEDNESDAY WITH WINDS LIKELY DROPPING BELOW SCA LEVELS. DUE TO
THE PERSISTENT SW FLOW SEAS WILL LIKELY TAKE LONGER TO SUBSIDE
BELOW SCA LEVELS. THE PROTECTED BAYS WILL LIKELY SEE WINDS AND
SEAS STAY MOSTLY BELOW SCA LEVELS.
&&
.HYDROLOGY...
EXPECTING 1 TO 4 INCHES OF RAIN WITH HURRICANE ARTHUR... WHICH MAY
CAUSE FLASH FLOODING. HEAVIEST RAIN WILL BE OVER THE MIDCOAST
REGION. IT IS POSSIBLE THAT SOME OF THE PRIMARY RIVERS ACROSS THE
MIDCOAST AREA COULD SEE SIGNIFICANT RISES BY SATURDAY MORNING.
