AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CARIBOU ME 1207 AM EDT THU JUN 11 2015 .SYNOPSIS... A FRONTAL SYSTEM WILL CROSS THE REGION THURSDAY. HIGH PRESSURE BUILDS THURSDAY NIGHT INTO FRIDAY. LOW PRESSURE MOVES INTO THE AREA FRIDAY NIGHT AND EXITS SATURDAY MORNING. HIGH PRESSURE RETURNS LATER SATURDAY INTO MONDAY. && .NEAR TERM /THROUGH THURSDAY/... UPDATE 1205 AM EDT: HAVE ADJUSTED TEMPERATURE... DEW POINT AND WIND BASED ON LATEST OBSERVATIONS. NO OTHER CHANGES PREVIOUS DISCUSSION... THE MAIN FORECAST CONCERN FOR THE NEAR TERM IS A COLD FRONT OVER QUEBEC THAT IS PROGGED TO TRACK EWD ACROSS MAINE LATE TONIGHT AND THURSDAY. MODELS ARE IN FAIRLY GOOD AGREEMENT BRING SCTD SHOWERS TO OUR WRN ZONES LATE TONIGHT...WHICH WILL THEN SPREAD EASTWARD ACROSS THE REST OF OUR CWA ON THURSDAY. WITH DAYTIME HEATING...INSTABILITY WILL INCREASE ACROSS THE AREA DURING THE DAY TOMORROW. AS A RESULT...THUNDERSTORMS WILL BECOME MORE LIKELY...ESPECIALLY BY THURSDAY AFTERNOON. THERE ARE FAIRLY LARGE DIFFERENCES BETWEEN CAPE VALUES BETWEEN THE NAM AND THE GFS...SO WILL USE A BLEND OF THE TWO WHICH WILL RESULT IN 0-3KM MUCAPE VALUES REACHING 1000 J/KG ACROSS OUR ERN AND SRN INLAND ZONES TOMORROW AFTERNOON. THIS COULD RESULT IN SOME STRONG STORMS WITH GUSTY WINDS AND SMALL HAIL. && .SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/... HIGH PRESSURE BUILDS THURSDAY NIGHT INTO FRIDAY WITH LESS HUMID AIR. LOWS WILL BE IN THE MID TO UPPER 50S. THE NARROW HIGH CROSSES THE AREA FRIDAY...PROVIDING A LOT OF SUNSHINE AND HIGHS IN THE UPPER 70S TO LOWER 80S. A WELL-MIXED BOUNDARY LAYER WILL PROVIDE WIND GUSTS AS HIGH AS 30 MPH...ESPECIALLY IN NORTHERN ZONES. FOR FRIDAY NIGHT...THE HIGH MOVES QUICKLY TO THE EAST AND A SHORTWAVE TRAVELS RAPIDLY INTO THE AREA FROM THE GREAT LAKES REGION. THIS SHORTWAVE WILL AMPLIFY AS IT MOVES ACROSS THE AREA LATER IN THE NIGHT AND BE ACCOMPANIED BY A DEEPENING SURFACE LOW THAT WILL MOVE ACROSS THE DOWN EAST REGION EARLY SATURDAY MORNING. STRONG LIFT WILL GENERATE A SWATH A PERIOD OF HEAVY RAINFALL. IT IS A BIT EARLY TO NAIL DOWN THE EXACT LOCATION OF THE HEAVIEST RAIN...BUT HAVE TAKEN A MEAN OF MODEL GUIDANCE AND GENERATED THE HIGHEST POPS AND QPFS FOR A LINE FROM SOUTHERN PISCATAQUIS TOWARDS SOUTHERN AROOSTOOK COUNTY. ALONG THIS LINE...OVER AN INCH OF RAIN COULD FALL LATE FRIDAY NIGHT INTO EARLY SATURDAY MORNING. THERE IS ALSO A CONCERN ABOUT ELEVATED INSTABILITY SOUTH OF THIS LINE FOR SOUTHERN PENOBSCOT...HANCOCK AND WASHINGTON COUNTIES...BUT WILL HOLD OFF ON MENTION OF THUNDERSTORMS FOR NOW. THE RAIN WILL MOVE OUT QUICKLY SATURDAY MORNING...EXITING WASHINGTON COUNTY BY MIDDAY AND OTHER REGIONS EARLIER. SKIES WILL GENERALLY CLEAR DURING THE AFTERNOON WITH JUST A FEW AFTERNOON SHOWERS TOWARDS THE CROWN OF MAINE AS THE COLD UPPER TROUGH CROSSES. HIGHS ON SATURDAY WILL BE MUCH COOLER WITH READINGS IN THE LOWER 70S AND LOWER HUMIDITY. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... AS THE PREVIOUS SYSTEM DEPARTS HIGH PRESSURE WILL SLIDE EAST ACROSS THE REGION SATURDAY NIGHT THROUGH SUNDAY NIGHT ALLOWING FOR LIGHT WINDS AND CLEAR SKIES. THE NEXT DISTURBANCE WILL APPROACH FROM THE WEST ON MONDAY...BRINGING INCREASING RAIN CHANCES LATER MONDAY INTO TUESDAY MORNING. RIGHT NOW THERE IS GOOD GENERAL MODEL AGREEMENT ON THIS DISTURBANCE THOUGH THERE ARE STILL SOME MINOR DIFFERENCES ON TIMING. THE ECMWF IS ABOUT 6 HOURS OR SO AHEAD OF THE GFS ON TIMING...WITH THE ECMWF HAVING PRECIPITATION ARRIVING A BIT BEFORE 06Z TUESDAY. GIVEN GOOD AGREEMENT ON THE EXISTENCE OF THE FEATURE, POPS WERE INCREASED TO 30-40% ACROSS MUCH OF THE AREA BETWEEN 06Z TUESDAY AND 00Z WEDNESDAY, WITH SLIGHTLY HIGHER POPS TO THE NORTH. WINDS WERE INCREASED 5-10 KNOTS IN THE MARINE ZONES ON TUESDAY AHEAD OF THE LOW AS MODEL WINDS WERE TOO LOW. HIGH PRESSURE APPEARS LIKELY TO BUILD IN BY THE MIDDLE OF NEXT WEEK...WITH CLEARING SKIES. && .AVIATION /04Z THURSDAY THROUGH MONDAY/... NEAR TERM: CONDITIONS WILL DETERIORATE LATE TONIGHT AND THURSDAY MORNING AND SHOWERS AND STORMS OVERSPREAD THE FCST AREA. PATCHY/AREAS OF FOG ARE ALSO POSSIBLE LATE TONIGHT/EARLY THURSDAY MORNING. LOCAL IFR/MVFR CONDITIONS ARE POSSIBLE IN THE SHOWERS AND PATCHY FOG. SHORT TERM: EXPECT MOSTLY VFR THURSDAY NIGHT INTO SATURDAY.

NEAR TERM: WAVE HEIGHTS WILL STAY JUST BELOW SMALL CRAFT ADVISORY CRITERIA UNTIL THURSDAY AFTERNOON. THEN WINDS WILL PICK UP ENOUGH WHERE A SMALL CRAFT ADVISORY FOR SEAS MAY BE NEEDED...POSSIBLY INTO THURSDAY NIGHT. SHORT TERM: NO ADVISORIES ARE ANTICIPATED.
