NWS Gray, ME wrote its last area forecast discussion before the first event at Jun 8, 6:36 PM EST, 1 hour 9 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAY ME 736 PM EDT WED JUN 8 2011 .SYNOPSIS... A RIDGE OF HIGH PRESSURE WILL BRING HOT AND HUMID WEATHER TO MUCH OF THE AREA THROUGH THURSDAY. A COLD FRONT WILL CROSS THE AREA THURSDAY NIGHT...WITH THUNDERSTORMS EXPECTED AHEAD OF IT. SOME OF THE THUNDERSTORMS COULD BE SEVERE. COOLER AND DRIER WEATHER IS EXPECTED TO FOLLOW THIS FRONT FRIDAY AND SATURDAY. LOW PRESSURE MAY BRING A CHANCE OF RAIN LATE SUNDAY INTO MONDAY. HIGH PRESSURE WILL BUILD OVER THE REGION LATE MONDAY THROUGH WEDNESDAY PRODUCING MOSTLY SUNNY SKIES AND DRY WEATHER. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... PRODUCTS UPDATE TO INCLUDE SEVERE TSTM WATCHES FOR ALL BUT SE NH AND THE WRN MOUNTAINS AND FOOTHILLS OF MAINE THRU THIS EVENING. WILL UPDATE TO ADJUST SKY COVER AND CHC OF PRCP INTO THIS EVENING PER LATEST SATELLITE LOOP AND RADAR MOSAIC LOOP. NO ECHOES OVER THE FCST AREA AT THIS TIME BUT ISOLD TO MAYBE SCT CONVECTION WILL SPREAD INTO THE N/MT ZONES THRU THE EARLY EVENING HOURS. MOST CLOUDS LIMITED TO PARTS OF THE N/MT ZONES AND ALONG THE MID COAST AND OFFSHORE WHERE REGION OF STRATUS CLOUDS MOVING TOWARD THE COAST FROM THE OCEAN. ANY OTHER CHANGES JUST VERY MINOR TWEAKS BASED ON LATEST OBSERVED DATA. PREVIOUS DISCUSSION... LACK OF ADEQUATE MOISTURE HAS LIMITED CONVECTIVE POTENTIAL THIS AFTERNOON ACROSS MAINE AND NEW HAMPSHIRE. SOME GROWING CUMULUS FIELDS HAVE BEEN NOTED ON SATELLITE ACROSS THE HIGHER TERRAIN OF VERMONT IN AN AREA OF GREATER MOISTURE LEVELS...INCLUDING DEWPOINTS IN THE UPPER 60S TO NEAR 70 DEGREES. EXPECT THE STRENGTH OF THE UPPER RIDGE AND WARM AIR ALOFT TO PREVENT THUNDERSTORM DEVELOPMENT THIS AFTERNOON...THOUGH IF A STORM CAN DEVELOP OVER THE HIGHER TERRAIN AND MOVE INTO NEW HAMPSHIRE IT COULD BECOME SEVERE WITH DAMAGING WINDS AND LARGE HAIL. THE GREATER THREAT FOR THUNDERSTORMS WILL BE TONIGHT. THERE MAY BE A COMPLEX OF THUNDERSTORMS DEVELOPING ALONG THE COLD FRONT IN ONTARIO AND QUEBEC THIS AFTERNOON. THESE MAY MOVE INTO NORTHERN NEW ENGLAND...ESPECIALLY NORTHERN MAINE AND NEW HAMPSHIRE LATER THIS EVENING AND OVERNIGHT. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/... THE HOT AND HUMID AIR MASS OVER NEW YORK AND WESTERN VERMONT TODAY WILL ADVECT EASTWARD ON WESTERLY WINDS BY THURSDAY. A COLD FRONT WILL BE APPROACHING FROM THE NORTH OUT OF QUEBEC. THE COMBINATION OF LIFT ASSOCIATED FROM THE FRONT AND THE INSTABILITY GENERATED BY THE HIGH LOW LEVEL HEAT AND HUMIDITY WILL LEAD TO SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS BY THURSDAY AFTERNOON. OVERALL WIND SHEAR WILL BE MARGINALLY CONDUCIVE FOR MULTICELL OR EVEN SUPERCELL STORM STRUCTURE...ESPECIALLY FURTHER TO THE NORTH AND LATER IN THE EVENING. THIS WILL BRING A THREAT FOR LARGE HAIL AND DAMAGING WINDS WITH THE THUNDERSTORMS THROUGH THURSDAY EVENING. THE COLD FRONT WILL PASS THROUGH THURSDAY NIGHT...BRINGING COOLER AND DRIER AIR INTO THE AREA. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... FRONTAL BOUNDARY MOVES OFFSHORE EARLY FRIDAY WITH COOLER AND DRIER AIR FILTERING IN FROM THE NORTH. ZONAL FLOW ALOFT WILL KEEP THINGS MOVING THOUGH AS ANOTHER SURFACE LOW APPROACHES THE REGION FROM THE WEST ON SATURDAY. THIS SYSTEM WILL TAKE A LITTLE LONGER TO MOVE THROUGH AND WILL PRODUCE A THREAT OF RAIN THROUGH SUNDAY NIGHT. AS THE UPPER LEVEL FLOW TURNS MORE TO THE NORTHWEST HIGH PRESSURE WILL BEGIN TO BUILD OVER NEW ENGLAND AT THE SURFACE LATE MONDAY AND THROUGH WEDNESDAY. && .AVIATION /00Z THURSDAY THROUGH MONDAY/... SHORT TERM /THROUGH THURSDAY NIGHT/...SVR TSTM WATCH INCLUDES LEB AND CON THRU 11 PM THIS EVENING. STRONG TO PSBL SVR TSTMS EXPECTED AND THEY MAY MOVE TOWARD THE OTHER TAF SITES LATER ON THIS EVENING OR POSSIBLY OVERNIGHT. MORE STRONG CONVECTION PSBL ON THURSDAY WITH A SLGT RISK OF SVR WX. SOME STRATUS AND F MAY MOVE IN OFF THE OCEAN TNGT LOWERING CIG AND VSBY TO IFR/LIFR AT PWM AND AUG AND POSSIBLY AS FAR W AS PSM. NOT EXPECTING MUCH AT CON AND LEB THOUGH IF THEY GET A PERIOD OF RN FROM A TSTM THEN THAT COULD LEAD TO SOME LOCAL F FORMATION OVERNIGHT. CD FNT MOVES THRU WITH FAIR WX TO FOLLOW THURSDAY NGT. LONG TERM...VFR CONDITIONS ARE EXPECTED THROUGHOUT THE PERIOD WITH SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS LATE SATURDAY AND SUNDAY. && .MARINE... SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/...WINDS AND SEAS REMAIN BELOW SCA LEVELS. MAIN CONCERN IS A STRONG COLD FRONT THAT WILL MOVE ACROSS THE WATERS THURSDAY NGT. STRONG TSTMS ARE PSBL AHEAD OF THE FNT WITH WINDS SHIFTING FROM SW TO NW WITH THE PASSAGE OF THE FNT. LONG TERM...LOOKS QUIET ON THE WATERS. && .GYX WATCHES/WARNINGS/ADVISORIES... ME...NONE.
