A stalled frontal boundary across northern portions of the forecast area was the focus for afternoon convection on the afternoon of June 23rd. A weak shortwave swinging in from the west helped to increase wind fields aloft and strong heating south of the front produced CAPES in the 1000 to 1500 j/kg range.

The episode as NWS GYX wrote it up.
A stalled frontal boundary across northern portions of the forecast area was the focus for afternoon convection on the afternoon of June 23rd. A weak shortwave swinging in from the west helped to increase wind fields aloft and strong heating south of the front produced CAPES in the 1000 to 1500 j/kg range. Large hail and damaging winds were the main threats with these storms, the stronger of which held together long enough to drift into southern portions of the region later in the day.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Gray, ME wrote its last area forecast discussion before the first event at Jun 23, 2:42 PM EST, 43 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAY ME 342 PM EDT SUN JUN 23 2013 .SYNOPSIS... WARM AND MOIST AIR CONTINUES TO POOL SOUTH OF A STATIONARY FRONT TO OUR NORTH. SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED EACH DAY THROUGH THE WEEK AS SEVERAL DISTURBANCES CROSS THE REGION. A LARGE UPPER LEVEL TROUGH WILL APPROACH FROM THE WEST LATE IN THE WEEK. THIS WILL ALLOW FOR COOLER TEMPERATURES...BUT INCREASE THE CHANCE FOR SHOWERS ACROSS THE REGION. && .NEAR TERM /TONIGHT/... MESOSCALE MODELS LIKE THE HRRR HAVE A GOOD HANDLE ON ONGOING CONVECTION TO OUR WEST. SHOWERS AND THUNDERSTORMS WHICH HAVE FORMED IN THE HIGHER TERRAIN WILL COALESCE AND SPREAD DOWNSTREAM IN THE NEXT FEW HOURS AS A COLD POOL DEVELOPS. SHOWERS AND THUNDERSTORMS SHOULD FORM A LOOSE MULTICELL LINE OVER CENTRAL/SOUTHERN NEW HAMPSHIRE AND INTO SW MAINE...MOVING OFFSHORE THIS EVENING. THE SEVERE WEATHER THREAT LOOKS HIGHEST OVER SOUTHERN AND CENTRAL NEW HAMPSHIRE WHERE MORE INSOLATION HAS OCCURRED AND SURFACE-BASED CAPES OF 1200-1500 J/KG RESIDE. THE BIGGEST SEVERE WEATHER THREAT WILL BE DAMAGING WINDS. TRAINING...AMPLE UNIDIRECTIONAL SHEAR...AND PRECIPITATION LOADING WILL SUPPORT THE THREAT OF WET DOWNBURSTS. FACTORS LIMITING SEVERE WEATHER INCLUDE THE LACK OF ANY REAL FOCUSING MECHANISM OR UPPER LEVEL SUPPORT...AS WELL AS A RELATIVELY HIGH FREEZING LEVEL. NEW STORMS WILL LIKELY DEVELOP ALONG OUTFLOW MERGERS AND IN AREAS OF DIFFERENTIAL HEATING. GYX SOUNDING FROM THIS MORNING HAS 1.72 INCHES OF PRECIPITABLE WATER...WHICH IS CLOSE TO 2 STANDARD DEVIATIONS ABOVE NORMAL FOR THE END OF JUNE. SATURATED AND WARM CLOUDS WILL CONTINUE TO SUPPORT VERY HEAVY RAIN AND WARM RAIN PROCESSES. QPF AMOUNTS FOR THIS EVENING WILL VARY WIDELY DEPENDING ON WHERE CONVECTION DEVELOPS. TRAINING CELLS AND ANY UPSLOPE COMPONENT WILL HELP TO LOCALLY BOOST RAINFALL TOTALS OVER ISOLATED AREAS...PERHAPS 1-2 INCHES. OTHER LOCATIONS MAY SEE LESS THAN A TENTH OF AN INCH. MUCH OF THE ACTIVITY WILL DIMINISH WITH THE LOSS OF DIURNAL HEATING...AND AS A WEAK SURFACE TROUGH SHIFTS OFFSHORE. OVERNIGHT LOWS WILL BE IN THE LOWER TO MID 60S AS THE LOWER LEVELS OF THE ATMOSPHERE REMAIN SATURATED...LEADING TO PATCHY DENSE FOG DEVELOPMENT. && .SHORT TERM /MONDAY THROUGH MONDAY NIGHT/... ANOTHER WEAK TROUGH CROSSES THE AREA TOMORROW WITH NEARLY ZONAL FLOW ALOFT. SKIES WILL BE PARTLY CLOUDY ACROSS THE SOUTH INITIALLY...AND THIS ALONG WITH WESTERLY WINDS WILL HELP BOOST TEMPERATURES INTO THE 80S AND 90S. DEW POINTS REMAIN IN THE UPPER 60S MAKING FOR AN UNPLEASANTLY MUGGY DAY. HEAT INDEX VALUES REACH THE LOWER 90S...STAYING SHORT OF ADVISORY CRITERIA. MOISTURE WILL BE WRUNG OUT ONCE AGAIN IN THE FORM OF AFTERNOON AND EVENING THUNDERSTORMS. HIGHER INSTABILITY WILL BE LOCATED OVER NORTHERN AREAS...BUT A THUNDERSTORM COULD POP UP ANYWHERE WITH BROAD WEAK FORCING. && .LONG TERM /TUESDAY THROUGH SUNDAY/... WARM AND HUMID WEATHER WILL CONTINUE THROUGH TUESDAY AND INTO WEDNESDAY. WARM 850 MB TEMPERATURES OF +18C COULD LEAD TO HIGHS REACHING THE 90 DEGREE MARK ACROSS SOUTHERN AND EASTERN NEW HAMPSHIRE AND SOUTHWEST MAINE. WITH DEW POINTS IN THE UPPER 60S TO LOW 70S... IT WILL BE HUMID. HEAT INDEX READINGS WILL TOP 90 DEGREES ACROSS THE COASTAL PLAIN OF MAINE AND NEW HAMPSHIRE... WITH SOME READINGS APPROACHING 95. ALTHOUGH THIS IS SHORT OF ADVISORY LEVELS... IT WILL STILL BE NOTICEABLY HOT AND HUMID. WITH HOT AND HUMID WEATHER COMES THE THREAT OF THUNDERSTORMS. A SHORTWAVE TROUGH WILL BE CROSSING SOUTHERN CANADA AND INTO NORTHERN NEW ENGLAND ON TUESDAY... ADDING UPPER LEVEL SUPPORT TO AN UNSTABLE AIR MASS TO PRODUCE THUNDERSTORMS ACROSS THE REGION. NAM IS SHOWING STRONGER MID AND UPPER LEVEL FLOW THAN THE GFS... AND IF THIS IS THE CASE THEN THERE WILL BE AMPLE DEEP LAYER SHEAR TO SUPPORT SUPERCELLS AND MULTICELL CLUSTERS AS DESCRIBED BY THE STORM PREDICTION CENTER IN THEIR MORNING OUTLOOK INDICATING A SLIGHT RISK ACROSS NORTHERN NEW ENGLAND. THE UNIDIRECTIONAL SHEAR INDICATES THAT THERE WILL BE PRIMARILY A DAMAGING WINDS AND HAIL THREAT RATHER THAN A TORNADO THREAT. IN ADDITION... THE HUMID AIR WILL ALLOW THUNDERSTORMS TO DROP VERY HEAVY RAINFALL. ANY TRAINING THUNDERSTORMS COULD LEAD TO FLASH FLOODING. WITH HIGH DEW POINTS EXPECTED... DO NOT EXPECT TEMPERATURES TO COOL OFF MUCH TUESDAY NIGHT. AFTER HIGHS IN THE 90S AND DEW POINTS IN THE UPPER 60S TO LOW 70S... IT WILL BE DIFFICULT FOR TEMPERATURES TO FALL MUCH BELOW 70 FOR MOST AREAS IN THE FEW HOURS OF NIGHT THAT EXIST THIS TIME OF YEAR. AS A RESULT... RAISED LOW TEMPERATURES FROM GUIDANCE VALUES AS MAV/MET TEND TO BE TOO COLD ON HUMID NIGHTS SUCH AS THIS. ANOTHER SHORTWAVE TROUGH CROSSES THE AREA TUESDAY NIGHT OR WEDNESDAY AND WILL PROVIDE ANOTHER CHANCE FOR SHOWERS AND THUNDERSTORMS. TIMING DIFFERENCES IN THE MODELS MAKES IT DIFFICULT TO PROVIDE MORE CONFIDENCE VIA HIGHER POP VALUES. GFS AND CMC BOTH SEEM TO BE SUFFERING FROM FEEDBACK RESULTING FROM CONVECTION. GFS DEVELOPS A CLOSED 999 MB SURFACE LOW CROSSING THE AREA TUESDAY NIGHT WHILE THE CMC IS SIMILAR BUT NOT AS STRONG. THIS SOLUTION SEEMS UNLIKELY AND WAS DISCOUNTED IN FAVOR OF THE ECMWF WHICH SHOWS A MORE PROGRESSIVE SHORTWAVE CROSSING THE REGION. A COLD FRONT DROPS SOUTH ACROSS THE AREA ON WEDNESDAY... BRINGING COOLER AIR DOWN FROM THE GULF OF SAINT LAWRENCE AND EASTERN CANADA. 850 TEMPERATURES DROP ABOUT 4C WEDNESDAY AS COMPARED TO TUESDAY AND MAX TEMPERATURES SHOULD REFLECT THIS. HOWEVER... DOWNSLOPING NORTHWEST WINDS WILL PROVIDE FOR DEEP MIXING ALONG THE COASTAL PLAIN OF NEW HAMPSHIRE AND SOUTHWEST MAINE... ALLOWING TEMPERATURES TO CLIMB INTO THE MID TO UPPER 80S FOR ONE MORE DAY. HIGH PRESSURE BUILDING SOUTH OUT OF EASTERN CANADA WILL BRING AN EASTERLY TO SOUTHEASTERLY FLOW ON THURSDAY. ECMWF SHOWS A PRONOUNCED EASTERLY FLOW ACROSS THE AREA WHICH WOULD KEEP A COOL MARINE AIR MASS IN PLACE. WATER TEMPERATURES OFF THE NEW HAMPSHIRE COAST AREA IN THE LOW 60S... WHILE WATER TEMPERATURES OFF THE MIDCOAST OF MAINE ARE IN THE LOW 50S. EVEN THE GFS SHOWS A SOUTH TO SOUTHEAST FLOW ON THURSDAY WHICH WOULD KEEP MUCH OF MAINE COOL. AS A RESULT... HAVE GONE WITH COLDER TEMPERATURES FOR WEDNESDAY WITH HIGHS IN THE LOW 70S ACROSS MAINE TO THE UPPER 70S FOR NEW HAMPSHIRE. THIS WAS MORE IN LINE WITH THE ECMWF MOS AND HPC. ALL MODELS NOW IN GOOD AGREEMENT THAT A LARGE SCALE TROUGH WILL BE APPROACHING THE AREA BY THURSDAY NIGHT... SPREADING BROAD SCALE LIFT OVER NEW ENGLAND IN COMBINATION WITH AN ONSHORE SOUTHEAST FLOW. AS A RESULT... INCREASED POPS INTO THE 60 TO 70 PERCENT RANGE TO REFLECT THE INCREASED CONFIDENCE IN TIMING. UNFORTUNATELY... THIS BROAD SCALE TROUGH LINGERS TO THE WEST OF NEW ENGLAND THROUGH THE WEEKEND... LEAVING THE FORECAST AREA WITHIN THE FAVORABLE AREA FOR RISING MOTION AND PRECIPITATION. TIMING OF SUBTLE SHORTWAVE TROUGHS WITHIN THE FLOW AND ASSOCIATED SURFACE FEATURES VARIES AMONG THE MODELS AND IS DIFFICULT TO FORECAST THIS FAR OUT. AS A RESULT... HAVE INDICATED A CHANCE OF SHOWERS OR THUNDERSTORMS FROM FRIDAY THROUGH THE WEEKEND. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... SHORT TERM...VFR SKIES IN VCTS THIS EVENING. SHOWERS AND THUNDERSTORMS DIMINISH OVERNIGHT WITH PATCHY DENSE FOG AND STRATUS DEVELOPING. MOISTURE TRAPPED UNDER AN INVERSION WILL KEEP PERIODS OF LIFR AND VLIFR CEILINGS IN THE TERMINAL FORECASTS. WEST WINDS ON MONDAY MAY GUST INTO THE LOWER 20S. LONG TERM...OVERNIGHT FOG IS POSSIBLE EACH NIGHT IN THE VALLEY LOCATIONS... AS WELL AS AFTERNOON HAZE AND THUNDERSTORMS THROUGH TUESDAY. A COLD FRONT BRINGS COOLER AIR IN FOR WEDNESDAY. AN ONSHORE FLOW ON THURSDAY COULD BRING IFR CONDITIONS PERHAPS WORSENING TO LIFR BY THURSDAY NIGHT AND FRIDAY IN SHOWERS. && .MARINE... SHORT TERM...HELD OFF ON A SMALL CRAFT ADVISORY AS GUIDANCE HAS BEEN OVERDOING WAVE HEIGHTS. THAT SAID A FEW 5-6 FOOTERS MAY DEVELOP ON THE FAR OUTER WATERS. WINDS WILL STAY BELOW 25 KTS WITH A FEW GUSTS INTO THE LOWER 20S. LONG TERM...EXPECT A GENERAL SOUTHWEST FLOW OVER THE WATERS THROUGH WEDNESDAY THOUGH IT SHOULD REMAIN BELOW 25 KT. GFS MODEL IS FORECASTING A STRONGER SURFACE LOW TO CROSS INTO THE GULF OF MAINE FROM THE WEST ON WEDNESDAY BUT THIS IS LIKELY OVERDONE DUE TO CONVECTION WITHIN THE MODEL. AS A RESULT... WAVE HEIGHTS GENERATED BY THE WNA WAVE MODEL WERE TOO HIGH ON THE SOUTHWEST FLOW AHEAD OF THE FRONT. EXPECT WINDS AND WAVES TO STAY BELOW SMALL CRAFT ADVISORY CONDITIONS AHEAD OF AND BEHIND THE FRONT ON WEDNESDAY. HIGH PRESSURE DROPS SOUTH OUT OF CANADA AND INTO THE WESTERN ATLANTIC AND GULF OF MAINE FOR THURSDAY WITH A SOUTHERLY FLOW RETURNING BY FRIDAY. && .TIDES/COASTAL FLOODING... A PORTLAND HIGH TIDE OF 11.8 FT IS EXPECTED TONIGHT AT 11:41 PM. FLOOD STAGE AT PORTLAND IS 12.0 FT. WINDS WILL BECOME WSW TONIGHT AND NEARLY PARALLEL TO THE COAST. THIS IS NOT A FAVORED DIRECTION FOR COASTAL EROSION OR SPLASH OVER. && .GYX WATCHES/WARNINGS/ADVISORIES... ME...NONE. NH...NONE. MARINE...NONE. && HANES/KIMBLE
