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 22, 9:25 AM EST, 3 hours 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAY ME 1025 AM EDT FRI JUN 22 2007 .SYNOPSIS... LOW PRESSURE SPINNING OVER THE MARITIMES WILL PRODUCE A CYCLONIC FLOW OVER NORTHERN NEW ENGLAND TODAY...WITH MORE SCATTERED SHOWERS AND THUNDERSTORMS INTO TONIGHT. COOL AIR FOR LATE JUNE WILL PREVAIL THIS WEEKEND WITH A CHANCE OF SHOWERS SUNDAY. A WARM FRONT WILL PASS NORTH ON TUESDAY...WITH THE POTENTIAL FOR HOT WEATHER GOING INTO MIDWEEK. COOLER AIR WILL FOLLOW TO END THE WEEK. && .NEAR TERM /UNTIL 8 PM THIS EVENING/... THE NEARLY STACKED LOW OVER NEW BRUNSWICK AND EASTERN MAINE WILL MAINTAIN A CYCLONIC FLOW OVER THE FORECAST FOR THE NEAR FUTURE. THE FORECAST PROBLEMS FOR THE BALANCE OF THE DAY ARE CLOUDS AND CONVECTION. OVERALL...THE ATMOSPHERE IN PLACE IS RELATIVELY COLD AND MOIST. MORNING SOUNDINGS SHOWS UNSTABLE CONDITIONS IN PLACE ALREADY... WITH LOW FREEZING LEVELS AND WET BULB ZERO VALUES. WIDELY SCATTERED SHOWERS HAVE ALREADY DEVELOPED...WITH LARGE BREAKS IN THE CLOUDS ACROSS MUCH OF WESTERN MAINE THIS MORNING. GIVEN THAT THE CONVECTIVE TEMPERATURES ARE WELL WITHIN REACH AND TEMPERATURES REMAIN COLD IN THE MID LEVELS...THE SUNSHINE THIS MORNING SHOULD BE SELF-DESTRUCTIVE...AND ALL AREAS SHOULD SEE SKIES BECOME MOSTLY CLOUDY. MORNING SOUNDINGS SUGGEST HIGHS IN THE 60S...AND MAINTAINED A MENTION OF 70 DEGREES IN AREAS THAT ARE RECEIVING SUNSHINE THIS MORNING. WOULD EXPECT CONVECTION TO DEVELOP LATER THIS MORNING INTO THIS AFTERNOON. GIVEN THE WET BULB ZERO VALUES...SMALL HAIL SEEMS LIKELY WITH ANY CELL THAT GETS A ST0RM TOP HIGHER THAN 20000 FEET. MODIFYING THE MORNING SOUNDINGS PRODUCES NEARLY MODERATE INSTABILITY... AND GIVEN LOW DEW POINTS...AN INVERTED V PROFILE IS EXPECTED. THIS COULD RESULT IN A WIND GUST POTENTIAL...BUT AT THIS TIME WINDS ARE EXPECTED TO REMAIN BELOW 58 MPH IN GUSTS. THE ACTIVITY SHOULD PEAK IN THE MID TO LATE AFTERNOON...THEN WANE THIS EVENING. IN SHORT...SMALL HAIL AND WIND GUSTS TO 45 MPH CAN BE EXPECTED WITH ANY THUNDERSTORM THAT DEVELOPS TODAY. SHOULD STORM TOPS EXCEED 35000 FEET...LARGE HAIL AND DAMAGING WINDS ARE POSSIBLE...BUT THIS CHANCE IS NOT HIGH ENOUGH TO MENTION YET. && .SHORT TERM /8 PM THIS EVENING THROUGH 6 AM SATURDAY/... CYCLONIC FLOW ALOFT WILL REMAIN IN PLACE TONIGHT. AS DIURNAL COOLING OCCURS...EXPECT MOST OF THE CONVECTION TO DIE OFF. BOTH THE GFS AND THE NAM ARE IN PRETTY GOOD AGREEMENT WITH THIS. THE ONLY EXCEPTION WILL BE OVER THE MOUNTAINS OF NORTHERN NEW HAMPSHIRE AND WESTERN MAINE WHERE SOME INSTABILITY WILL REMAIN. MID LEVELS START TO DRY OUT A BIT...SO SHOULD SEE THE CLOUD COVER DIMINISH A BIT. RADIATIONAL COOLING COULD PRODUCE SOME PATCHY FOG...BUT WILL LEAVE THAT OUT OF THE FORECAST FOR THIS CYCLE. && .LONG TERM /SATURDAY THROUGH THURSDAY/... SATURDAY WILL FEATURE GUSTY WINDS AS UPPER LEVEL VORTEX EXITS E INTO THE CANADIAN MARITIMES. WINDS WILL ALIGN FROM THE WEST...AND WHEN COMBINED WITH DEEP MIXING LEVELS...WIND GUSTS WILL REACH 20 KT AT TIMES...ESPECIALLY UNTIL MIDDAY. WNW FLOW TO CONTINUE...WITH A LEAST ONE MORE PULSE OF ENERGY REINFORCING OUR UNSTABLE ATMOSPHERE ON SUNDAY. THEREAFTER...THERE IS STILL SOME QUESTION AS TO HOW MUCH WARM AIR WILL WIN OUT ATTEMPTING TO ENTER MAINE/NEW HAMPSHIRE BY TUESDAY. 00Z OPERATIONAL GFS RUN WOULD SUGGEST A RETURN TO SUMMER WARMTH BY TUESDAY...WITH OTHER MEDIUM RANGE MODELS COMING INTO LINE. && .AVIATION /14Z FRIDAY THROUGH TUESDAY/... VFR CONDITIONS ARE EXPECTED FOR THE MOST PART...WITH CEILINGS REMAINING ABOVE 3000 FEET. THE EXCEPTION WILL BE IN THE VICINITY OF THUNDERSTORMS...WHERE MVFR TO IFR CONDITIONS ARE POSSIBLE. FOR NOW...DUE TO UNCERTAINTY...RETAINED THE VCSH AND VCTS REMARKS UNTIL THE THREAT BECOMES BETTER ESTABLISHED. BASICALLY VFR CONDITIONS WITH LOCAL MVFR CONDITIONS AND ISOLATED SHOWERS IN THE MOUNTAINS SATURDAY AFTERNOON. SIMILAR CONDITIONS SUNDAY INTO EARLY MONDAY...FOLLOWED BY A SLACKENING AND BACKING OF THE WINDS TO THE SOUTHWEST NEXT WEEK. && .MARINE... IN THE NEAR TERM...WINDS ARE JUST BELOW SMALL CRAFT LEVELS IN THE WESTERLY FLOW. THE 12Z GYX SOUNDING SHOWS A FAIRLY NEUTRAL LAYER THROUGH 800 MB...WITH 25 KNOTS AVAILABLE IN THE LAYER. WHILE MIXING SHOULD BE FAIRLY EFFICIENT DUE COLD TEMPERATURES IN THE MID LEVELS... WILL HOLD OFF ON THE SMALL CRAFT ADVISORY FOR TODAY. SINCE 25 KNOTS IS ABOUT ALL THAT SHOULD BE AVAILABLE (THE BEST WINDS SHOULD DROP SOUTH OF THE WATERS THIS MORNING AND EARLY AFTERNOON)...THE GUSTS SHOULD NOT BE FREQUENT ENOUGH FOR A SMALL CRAFT ISSUANCE. WINDS WILL PICK UP ONCE AGAIN SATURDAY WITH THE PASSAGE AND EXITING OF THE UPPER TROUGH THROUGH THE CANADIAN MARITIMES. WINDS ALIGN WITH DEEP MIXING LEVELS OVER LAND. LESSOR MIXING WITH THE RELATIVELY COOL WATERS OF THE ATLANTIC...BUT STILL ENOUGH FOR 20 KT+ WIND GUSTS. && .GYX WATCHES/WARNINGS/ADVISORIES... ME...NONE. NH...NONE. MARINE...NONE. && NEAR TERM...HAYES SHORT TERM...HAYES AVIATION...HAYES MARINE...HAYES
