Severe Thunderstorm Warning 30, NWS Gray, ME

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME
340 PM EDT TUE JUN 9 2015

.SYNOPSIS...
A COLD FRONT WILL SLOWLY CROSS THE REGION TONIGHT AND WILL BE
FOLLOWED BY A RIDGE ON HIGH PRESSURE ON WEDNESDAY. LOW PRESSURE
CROSSING SOUTHERN CANADA WEDNESDAY NIGHT WILL DRIVE ANOTHER COLD
FRONT THROUGH THE REGION THURSDAY. HIGH PRESSURE WILL BUILD IN
FROM THE WEST THURSDAY NIGHT AND FRIDAY. LOW PRESSURE OVER THE
GREAT LAKES WILL TRACK NORTHEAST FRIDAY NIGHT AND WILL PUSH EAST
THROUGH NEW ENGLAND ON SATURDAY. HIGH PRESSURE WILL BUILD IN FROM
THE NORTHWEST SATURDAY NIGHT AND SUNDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
COLD FRONT APPROACHING FROM THE WEST CURRENTLY PUSHING A LINE OF
CONVECTION THROUGH EASTERN NEW YORK AND EXPECT THIS LINE TO HOLD
TOGETHER AS IT ENTERS THE CONNECTICUT VALLEY LATE THIS AFTERNOON.
SAT PICS SHOWING PARTIAL CLEARING ACROSS MUCH OF NEW HAMPSHIRE AND
TEMPERATURES ARE GRADUALLY RESPONDING SO SHOULD HAVE ENOUGH CAPE BY
THE TIME IT PUSHES INTO WESTERN ZONES TO SUSTAIN CONVECTION.

GENERALLY DEALING WITH MARGINAL CAPES DURING THE REMAINDER OF THE
AFTERNOON...BUT GOOD BULK SHEAR ACROSS THE AREA AND PWAT'S OF 1.4
TO 1.6 WILL INCREASE THE POTENTIAL FOR DAMAGING WINDS WITH
STRONGER CELLS AND BOWING LINE SEGMENTS. MAINE THREAT WILL BE
CONFINED TO NEW HAMPSHIRE AS CONTINUING ONSHORE FLOW HAS MUCH OF
MAINE UNDER A STRONG MARINE LAYER...SO EXPECT ANY CONVECTION TO
GRADUALLY DIE OUT AS IT ENTERS WESTERN MAINE. COULD SEE SOME SMALL
HAIL IN STRONGER CELLS IN NEW HAMPSHIRE BUT SHOULD REMAIN BELOW
SEVERE LIMITS DUE TO LIMITED CAPES.

SECOND CONCERN WILL BE FOR HEAVY RAINFALL IN NORTHWEST ZONES WHERE
OVER AN INCH HAS FALLEN IN THE PAST 24 HOURS. SHORTWAVE APPROACHING
FROM THE WEST WILL GO SLIGHTLY NEGATIVE AS IT SWINGS THROUGH
NORTHERN ZONES THIS EVENING MAY RESULT IN TRAINING CELLS AND
PERSISTENT HEAVY RAINFALL THROUGH MIDNIGHT IN THE MOUNTAINS OF
MAINE AND NEW HAMPSHIRE AND THIS WILL BE WATCHED CLOSELY THROUGH
THIS EVENING. EXPECT RAIN AND SHOWERS TO TAPER OFF AFTER MIDNIGHT
IN NORTHERN ZONES. LOWS OVERNIGHT WILL RANGE FROM THE MID 50S
NORTH TO THE LOWER 60S SOUTH.

&&

.SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/...
SKIES WILLL CLEAR WEDNESDAY MORNING AS A WEAK RIDGE OF HIGH
PRESSURE PUSHES IN FROM THE WEST. NOT A LOT OF COLD AIR BEHIND THE
THE FRONT SO TEMPS WILL BOUNCE BACK INTO THE MID 70S TO MID 80S
UNDER MOSTLY SUNNY SKIES. EXPECT WINDS TO BACK AROUND TO THE SOUTH
TO SOUTHWEST IN THE AFTERNOON CAPPING TEMPS IN MIDCOAST AREAS IN
THE LOWER 70S.

NEXT SHORTWAVE SWINGS IN FROM THE WEST WEDNESDAY NIGHT BRINGING
SHOWERS TO NORTHERN ZONES OVERNIGHT. NOT A LOT OF MOISTURE WITH
THIS SYSTEM AND WILL BE A QUICK HITTER WITH ASSOCIATED COLD FRONT
PUSHING OFFSHORE BY THURSDAY MORNING. OVERNIGHT LOWS WILL RANGE
FROM THE MID 50S NORTH TO THE MID 60S SOUTH.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
GENERALLY SPEAKING THE OUTLOOK PERIOD WILL BE COMPRISED OF A
SERIES OF FAST MOVING SYSTEMS WITH MILD TEMEPRATURES.

HIGH PRESSURE MOVES ACROSS THE REGION THURSDAY AND FRIDAY
PRODUCING DRY AND WARM CONDITIONS THEN MOVES OFFSHORE BY FRIDAY
NIGHT. THE NEXT CLIPPER SYSTEM WILL MOVE QUICKLY INTO THE
NORTHEAST FRI NIGHT AND THEN EXIT WELL OFF THE NEW ENGLAND COAST
BY LATE SAT...SHOWERS WILL BE ASSOCIATED WITH THIS SYSTEM. HIGH
PRESSURE RETURNS FOR A VERY NICE DAY ON SUNDAY AND WILL ALSO MOVE
OFFSHORE QUICKLY AND BY MONDAY ANOTHER SYSTEM, ALTHOUGH WEAKER,
WILL MOVE INTO THE AREA WITH SCATTERED SHOWERS RETURNING. MODELS
OVERALL IN CLOSE AGREEMENT ALTHOUGH SOME DIFFERENCES ON TIMING
WITH THE FAST MOVING SYSTEMS. THUS THE OUTLOOK PERIOD WAS BASED ON
A BLEND OF THE MODELS FOR BOTH TEMPERATURES AND PRECIPITATION.
