AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CARIBOU ME 251 PM EDT SAT JUN 30 2012 .SYNOPSIS... A SERIES OF DISTURBANCES WILL CROSS THE REGION THROUGH THE WEEKEND KEEPING UNSETTLED CONDITIONS ACROSS THE AREA. && .NEAR TERM /THROUGH SUNDAY/... THE MAIN CONCERN ONCE AGAIN WILL BE THE CHANCE FOR STRONG TO SEVERE CONVECTION LATE THIS AFTERNOON AND EARLY THIS EVENING IN ADVANCE OF AN UPPER TROF AND ASSOCIATED COLD FRONT APPROACHING FROM THE WEST. A FEW WEAK CELLS HAVE ALREADY BEGAN TO DEVELOP ACROSS PORTIONS OF THE CWA BUT THUS FAR HAVE BEEN BELOW SEVERE LIMITS. ATMOSPHERE NOT QUITE AS UNSTABLE AS YESTERDAY AS DEW POINTS AND CAPES ARE SOMEWHAT LOWER. THINK THE BIGGER POTENTIAL WILL BE LATER THIS AFTERNOON AND INTO THIS EVENING AS MESO SCALE MODELS ARE STILL INDICATING THE POTENTIAL FOR A LINE TO FORM IN MOVE INTO THE WESTERN PORTIONS OF THE CWA FROM QUEBEC JUST IN ADVANCE OF THE COLD FRONT. WILL CONTINUE TO REFERENCE DAMAGING WINDS AND LARGE HAIL WITH ANY THUNDERSTORMS THROUGH EARLY EVENING. ANY CONVECTION WILL DIMINISH EARLY TONIGHT AS THE COLD FRONT AND UPPER TROF SLOWLY MOVE OFF TO THE EAST. EXPECT SKIES TO BECOME PARTLY CLOUDY TO MAINLY CLEAR OVERNIGHT WITH LOWS FALLING INTO THE MID TO UPPER 50S NORTH AND LOW TO MID 6OS DOWNEAST. SUNDAY SHOULD BE A MAINLY DRY DAY. AN UPPER LEVEL TROF WILL STILL REMAIN ACROSS NORTHERN NEW ENGLAND AND TONIGHTS COLD FRONT WILL BE SLOW TO MOVE OFF THE COAST. THERE STILL COULD BE AN ISOLATED SHOWER ACROSS DOWNEAST AND WESTERN SECTIONS DURING THE AFTERNOON UNTIL THE COLD FRONT PUSHES EAST. HIGH TEMPERATURES ON SUNDAY WILL BE IN THE MID TO UPPER 70S NORTH AND LOW TO MID 80S DOWNEAST. && .SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/... A SHORTWAVE UPPER TROUGH MOVES THROUGH NEW ENGLAND ON MONDAY. EXPECT SCATTERED SHOWERS AND THUNDERSTORMS TO FIRE ALONG AN ASSOCIATED COLD FRONT. MUCAPE VALUES ARE BELOW 1000 J/KG... THEREFORE DO NOT ANTICIPATE ANY SEVERE WEATHER WITH THIS FRONTAL PASSAGE. HIGH PRESSURE BUILDS IN BEHIND THIS SYSTEM ON TUESDAY. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... NORTHERN AND DOWNEAST MAINE WILL SIT ON THE EDGE OF POLAR JET WITH A MASSIVE H5 RIDGE OVER MUCH OF CONUS. A SHORTWAVE TROUGH IS FORECAST TO MOVE THROUGH ON THE 4TH OF JULY AND WEDNESDAY NIGHT FOR A CHANCE OF SHOWERS AND THUNDERSTORMS. THE NEXT SHORTWAVE TROUGH IS PROJECTED FOR SATURDAY WITH THE NEXT CHANCE FOR SIGNIFICANT PRECIPITATION. OTHERWISE EXPECT ABOVE NORMAL TEMPERATURES AND MAINLY DRY CONDITIONS. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... NEAR TERM: MAINLY VFR CONDITIONS THROUGH SUNDAY. SCT TSTMS ARE EXPECTED TO BE IN THE VICINITY OF THE TERMINALS THIS AFTERNOON AND INTO THIS EVENING. THIS COULD RESULT IN LCL MVFR OR BRIEF IFR IN ANY OF THE STRONGER STORMS.
