IN THE SHORT TERM...WK FNTL BOUNDARY NOW MOVG ACRS NRN AND CNTRL PTNS OF THE FA. THE BEST INSTAB...OF COURSE...IS RIGHT ALG THIS LN ATTM. WUD EXPECT THIS ACTIVITY TO CONT AS THE FNT APCHS THE CST. WIND FIELD DO NOT APPEAR TO BE STG ENUF FOR ORGANIZED SVR...BUT INSTAB IS IMPRESSIVE. WL WATCH FOR HAIL AND WINDS FOR THE REMAINDER OF THE AFTN. INSTAB BHND THIS AS WELL...AS ACTIVITY IS FIRING ON ANOTHER OLD BOUNDARY IN QUEBEC. THIS ACTIVITY CUD SURVIVE TO AFFECT THE NRN AND CNTRL ZNS LATER THIS EVENING...SO MAY HAVE TO EXTEND THE EFFECTIVE TIME OF THE PCPN TIL MIDN THESE ZNS. MAY JUST LEAVE A MENTION FOR THE EVE FOR THE CST...BUT GIVEN THE AMS REMAINS UNSTABLE...MAY EXTEND THE MENTION THRU MIDN TO THE CST AS WELL. OTRW...NOT MUCH ELSE IN THE WAY OF FORCING FOR TNGT...SO WL PROBABLY DROP THE MENTION OF PCPN AS IT DIES OUT DURG THE EVENING. VIS LOOP SHOWS SUM ST ALG THE CST...ESP IN THE MID COAST REGION...SO WL BRING FG BACK INTO THE FCST. ELSEWHERE...WL MENTION PATCHY FOG...ESP WHERE RA FALLS. MOS MINS NUMBERS APPEAR OK...SINCE THERE IS REALLY NO AMS CHANGE BHND THIS BOUNDARY. FOR TUE...INGREDIENTS APPEAR TO AVBL FOR A DECENT CONVECTIVE EVENT TUE AFTN. LIMITING FACTOR CUD END UP BEING INSTAB...SINCE THE BREAKUP OF ANY ST...AND INFLUX OF MID LEVEL MOIST AHEAD OF THE FNT. BLV THAT THERE WL BE A PD OF SUN DURG THE MRNG. THIS SHUD ALLOW INSTAB TO MAXIMIZE IN THE AFTN. BEST CHC FOR SIG CONVECTION WUD BE SRN NH AND SWRN AND INTERIOR CNTRL...WHERE THE ONSHORE FLO SHUD BE MITIGATED.
