NWS Gray, ME wrote its last area forecast discussion before the first event at Jun 19, 9:32 AM EST, 3 hours 58 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAY ME 1032 AM EDT THU JUN 19 2008 .SYNOPSIS... A BROAD AREA OF WEAK LOW PRESSURE WILL MEANDER OVER NEW ENGLAND AND SOUTHERN QUEBEC THROUGH TONIGHT. A WEAK FRONTAL SYSTEM WILL CROSS NORTHERN NEW ENGLAND FRIDAY...FOLLOWED BY WEAK HIGH PRESSURE FOR SATURDAY. LOW PRESSURE APPROACHING FROM THE SOUTHWEST WILL BRING RAIN SUNDAY AND SUNDAY NIGHT. A COLD FRONT WILL SLOWLY CROSS THE REGION EARLY NEXT WEEK. && .NEAR TERM /UNTIL 8 PM THIS EVENING/... SATELLITE LOOKING SIMILAR TO PREVIOUS COUPLE OF MORNINGS WITH CLOUDS BREAKING UP IN NEW HAMPSHIRE AND LOW CLOUDS AND FOG ALONG THE MID MAINE COAST. LAST OF THE SHOWERS WERE EXITING FROM THE MAINE MOUNTAINS TO NORTHERN ME. INITIAL SHORT WAVE PIVOTING NORTHWARD AROUND THE UPPER LOW WHILE THE NEW ONE IN NEW YORK STATE WILL CROSS OUR AREA TODAY. DAYTIME HEATING WITH STEEPENING LAPSE RATES AND THE APPROACHING SHORT WAVE WILL GENERATE A FAIR AMOUNT OF CONVECTION TODAY. LOW WET BULB ZEROES SHOULD ONCE AGAIN LEAD TO HAIL IN THE STRONGER CELLS ALONG WITH GUSTY SURFACE WINDS. A FEW SHOWERS POPPING UP ALREADY IN NORTHERN NH. DAYTIME HIGHS WILL BE SIMILAR TO YESTERDAY AND AVERAGE A GOOD 5 TO 8 DEGREES BELOW NORMAL. && .SHORT TERM /8 PM THIS EVENING THROUGH 6 AM FRIDAY/... CONVECTION WINDS DOWN BY EVENING WITH LOSS OF HEATING AND PASSAGE OF THE SHORT WAVE. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... LOOKS LIKE STRATUS WILL BE IN PLACE NEAR THE COAST AS THE MOIST ONSHORE FLOW CONTINUES. WITH THE STRONG JUNE SUN...MOST LOCATIONS SHOULD SEE THE STRATUS AND PATCHY FOG EXITS BEFORE 1000 AM. AFTER THIS... ANOTHER SHORT WAVE ROTATING AROUND THE CLOSED LOW OVER WESTERN QUEBEC WILL CROSS THE REGION FRIDAY...WITH A SURFACE REFLECTION MOVING THROUGH DURING THE AFTERNOON. MID LEVEL TEMPERATURES WILL NOT BE AS COLD AS TODAY...AND MID LEVEL LAPSE RATES WILL BE WEAKER. HOWEVER...PRECIPITABLE WATER VALUES WILL RISE AHEAD OF THE SURFACE TROUGH...AS THE AIRMASS BECOMES A BIT WARMER. THE SURFACE TROUGH SHOULD ACT AS A FOCUS...RESULTING IN SHOWERS AND THUNDERSTORMS FOR MOST LOCATIONS. WILL NOT INDICATE WIND OR HAIL IN THE ZONE FORECASTS FOR FRIDAY...BUT THIS CAN BE REEVALUATED BY LATER SHIFTS. WITH AT LEAST SOME SUN IN THE LATE MORNING AND EARLY AFTERNOON...WOULD THINK THAT THE GFS MOS WOULD BE CLOSER TO THE TRUTH FOR HIGHS FRIDAY. THE CONVECTIVE POTENTIAL SHOULD WANE FRIDAY EVENING WITH THE LOSS OF DAYTIME HEATING BEHIND THE EXITING SHORT WAVE. HAVE NOT GONE COMPLETELY DRY AS THIS AIRMASS HAS BEEN TENACIOUS HOLDING ONTO CONVECTIVE WELL INTO THE NIGHT. MOS NUMBERS WERE CLOSE FOR LOWS AND ACCEPTED. THE CONVECTIVE POTENTIAL FOR SATURDAY SHOULD BE A TAD LESS THAN FRIDAY AS THE CLOSED SYSTEM OPENS INTO A TROUGH. HOWEVER...SINCE MID LEVEL TEMPERATURES ARE STILL FAIRLY COOL...A CHANCE OF SHOWERS AND THUNDERSTORMS WAS RETAINED. THE OVERALL AMOUNT OF ACTIVITY SHOULD BE LESS THAN PREVIOUS DAYS...AND GFS MOS NUMBERS LOOK BETTER FOR HIGHS IN THE GENERALLY WARMING AIRMASS. MODELS ARE IN GOOD AGREEMENT IN AN OVERRUNNING EVENT FOR SUNDAY AND SUNDAY NIGHT. WHILE THERE MAY BE SOME ELEVATED CONVECTION... THIS LOOKS MORE LIKE A STRATIFORM EVENT IN A PRE WARM FRONTAL ENVIRONMENT. MONDAY SHOULD BE A WARM SECTOR TYPE DAY WITH SCATTERED SHOWERS AND THUNDERSTORMS...WITH TUESDAY SHOWING BETTER CONVECTIVE POTENTIAL. && .AVIATION /14Z THURSDAY THROUGH MONDAY/... SHORT TERM /07Z THURSDAY THROUGH 11Z FRIDAY/...MVFR IN LOW CLOUDS AND FOG ALONG THE MIDCOAST THROUGH EARLY AFTERNOON...OTHERWISE VFR TODAY WITH BRIEFLY MVFR CONDITIONS IN SHOWERS AND THUNDERSTORMS. THUNDERSTORMS MAY CONTAIN WIND GUSTS TO 30 KT AND SMALL HAIL. VFR EXPECTED TONIGHT WITH POCKETS OF MVFR/IFR IN FOG. LONG TERM /FRIDAY THROUGH MONDAY/... IFR CONDITIONS ARE POSSIBLE AT KPWM AND KAUG AS THE STRATUS EXITS FRIDAY MORNING. AFTER THIS...VFR CONDITIONS CAN BE EXPECTED...WITH SCATTERED THUNDERSTORMS. THE STRATUS WILL RETURN FRIDAY NIGHT...BRINGING IFR CONDITIONS TO KPWM AND KAUG. A MORE WIDESPREAD IFR THREAT EXISTS FOR SUNDAY AND SUNDAY NIGHT IN OVERRUNNING. && .MARINE... SHORT TERM /TODAY AND TONIGHT/...QUIET ON THE WATERS WITH WINDS AND SEAS BELOW SCA. ONLY PROBLEM WILL BE BRIEFLY HIGHER WINDS AND SEAS IN ANY THUNDERSTORM ACTIVITY. LONG TERM.../FRIDAY THROUGH MONDAY/... FOR THE MOST PART...WINDS AND SEAS WILL REMAIN BELOW SMALL CRAFT LIMITS THROUGH THE PERIOD. SEA BREEZE CIRCULATIONS WILL ENHANCE THE GRADIENT FLOW EACH AFTERNOON AND EVENING FRIDAY AND SATURDAY... PRODUCING 20 KNOT GUSTS AT THE C MAN STATIONS. && .GYX WATCHES/WARNINGS/ADVISORIES...
