NWS Gray, ME wrote its last area forecast discussion before the first event at Jun 9, 2:40 PM EST, 1 hour 10 minutes earlier.
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. && .AVIATION /19Z TUESDAY THROUGH SUNDAY/... SHORT TERM...AREAS OF IFR/LIFR CEILINGS AND VSBY OVERNIGHT...IMPROVING TO VFR WEDNESDAY. AREAS OF MVFR CEILINGS WEDNESDAY NIGHT IN THE NORTH AND VFR ELSEWHERE. LONG TERM...VFR CONDITIONS THROUGH FRIDAY..THEN LOWER TO MVFR FRI NIGHT AND SAT IN SCATTERED SHOWERS. CONDITIONS RETURN TO VFR SAT NIGHT AND SUN. && .MARINE...
