Area forecast discussion, May 29, 1:05 AM EDT, 56 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAY ME 105 AM EDT TUE MAY 29 2012 .SYNOPSIS... A WARM FRONT WILL SLOWLY LIFT INTO SOUTHERN NEW ENGLAND OVERNIGHT, THEN STALL ACROSS THE REGION ON TUESDAY. A COLD FRONT WILL APPROACH FROM THE WEST TUESDAY NIGHT AND WILL CROSS THE AREA ON WEDNESDAY. A SECONDARY COLD FRONT WILL APPROACH FROM THE NORTHWEST WEDNESDAY NIGHT AND WILL PUSH SOUTH OF THE REGION ON THURSDAY. HIGH PRESSURE WILL BUILD IN FROM THE WEST THURSDAY NIGHT AND FRIDAY. LOW PRESSURE WILL MOVE EAST FROM THE GREAT LAKES FRIDAY NIGHT AND SATURDAY AND WILL SLOWLY MOVE EAST THROUGH NORTHERN NEW ENGLAND ON SUNDAY. LOW PRESSURE WILL DRIFT EAST OF THE REGION ON MONDAY. && .NEAR TERM /UNTIL 6 AM TUESDAY MORNING/... 1 AM UPDATE...NOCTURNAL MCS DEVELOPING OVER VT AND NH AS OF 05Z. EXPECT ISOLATED LARGE HAIL AND DAMAGING WINDS FOR THE NEXT SEVERAL HOURS...INCLUDING THE POTENTIAL FOR FLASH FLOODING IN AREAS OF TRAINING CELLS. 935 PM...AS EXPECTED...CONVECTION CONTINUES TO GRADUALLY INCREASE IN COVERAGE ACROSS THE REGION IN DEVELOPING OVERRUNNING PATTERN. I RAISED POPS TO LIKELY FOR AREAS VICINITY OF THE KENNEBEC VALLEY NEXT SEVERAL HOURS AND ADDED THUNDER AS WELL. 1ST PERIOD GRIDS WERE ADJUSTED BASED ON RADAR TRENDS AS WELL AS MESONET. 640 PM...SHOWERS CONTINUE OVER NORTHEAST MAINE IN ASSOCIATION WITH THE STALLED BACKDOOR FRONT. THE SECOND BAROCLINIC ZONE WAS SITUATED JUST SOUTH AND WEST OF THE FORECAST AREA WITH SCATTERED ECHOES OVER NORTHERN AND EASTERN SECTIONS OF OUR AREA AT MOMENT. EXPECT CONVECTION TO INCREASE IN COVERAGE OVERNIGHT AS MOISTURE AND WARM AIR ADVECTION INCREASES. FOR THIS ESTF UPDATE...ONLY MINOR TWEAKS WERE REQUIRED TO 1ST PERIOD GRIDS BASED PRIMARILY ON MESONET. PREV DISC... SPECIAL KALB SOUNDING IS HIGHLIGHTING CONVECTIVE INITIATION TROUBLE FOR THIS AFTN AND EVE ACROSS THE SWRN CWA. DESPITE STEEPENING LAPSE RATES ALOFT...BOUNDARY LYR MOISTURE IS NOT ABLE TO OVERCOME WARM TEMPS ALOFT. AS LAPSE RATES CONTINUE TO IMPROVE INTO TNGT AND MOISTURE CONTINUES TO RISE...CONDS WILL BECOME INCREASINGLY FAVORABLE FOR CONVECTION ACROSS THE AREA. THE OVERNIGHT FCST REMAINS SOMEWHAT UNCERTAIN REGARDING PLACEMENT AND COVERAGE OF TSTMS. INITIALLY THERE IS A SMALL CHC FOR SFC BASED TSTMS TO DEVELOP INVOF SWRN NH...BUT THAT WINDOW WILL CLOSE QUICKLY WITH LOSS OF DAYTIME HEATING. MORE LIKELY SCENARIO IS WITH MID LVL FNT TNGT. IN RESPONSE TO INCREASING HGT FALLS...MID LVL WARM FNT WILL BEGIN TO MOVE NWD...TO A POSITION ROUGHLY BISECTING THE CWA. ALONG THIS FNT...SLOPED ASCENT SHOULD INITIATE ELEVATED CONVECTION. MUCAPE VALUES REMAIN HIGH THRU THE NIGHT...WITH LAPSE RATES FAVORING HAIL PRODUCTION WELL INTO THE SFC MARINE LYR. HAVE ADDED SMALL HAIL AND HEAVY RAFL TO THE FCST GRIDS...THOUGH WOULD NOT BE SURPRISED TO SEE AT LEAST ISOLD SEVERE HAIL FROM ANY STORM GIVEN THE FAVORABLE EFFECTIVE SHEAR VALUES. THERE CONTINUES TO BE SUPPORT...MAINLY FROM THE 28/12Z NAM AND ECMWF...FOR THIS CONVECTION WITH UPR LVL DIVERGENCE AND HIGH MID LVL RH VALUES COLLOCATED OVER THE CNTRL CWA. THE 28/12Z GFS HAS A SIMILAR EVOLUTION...THOUGH DISPLACED ABOUT 100 MILES SWD...HENCE SOME REMAINING UNCERTAINTY. && .SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/... EARLY MORN CONVECTION SHOULD LIFT OUT OF THE CWA WITH TIME...AND EXPECT CLEARING TO DEVELOP IN THE FAR S AND W AGAIN. THOUGH THE HEART OF THE REMNANT ELEVATED MIXED LYR WILL BE DISPLACED E AND MODERATING WITH TIME...FAVORABLE LAPSE RATES LINGER OVER THE CWA THRU TUE EVE. INCREASING DEWPOINTS WILL YIELD MODERATE INSTABILITY...ESPECIALLY FOR THE CT RIVER VALLEY AND ADJACENT PARTS OF NH. IN ADDITION TO HAIL...STEEP LLVL LAPSE RATES WILL SUPPORT A DMGG WIND THREAT. PWAT VALUES INCREASING TO NEAR 1.50 INCHES WILL POOL AHEAD OF THE APPROACHING COLD FNT...MEANING HEAVY RAFL WILL ALSO BE PSBL WITH ANY TSTM. SELY LLVL FLOW VEERING TO NWLY ALOFT WILL ALSO SUPPORT SUPERCELLULAR CHARACTERISTICS...WITH AT LEAST AN ISOLD TORNADO THREAT...AGAIN ESPECIALLY FOR FAR WRN/SWRN NH. THIS WILL BE MOSTLY TIED TO THE SFC WARM FNT...IF IT CAN MAKE THE ADVANCE THIS FAR N. EXPECT THAT PRESSURE FALLS INCREASING IN SRN CANADA WILL PREVENT THE BOUNDARY FROM PULLING A BACKDOOR COLD FNT ROUTINE LIKE TODAY. SEVERE TSTM WORDING HAS BEEN INCLUDED FOR NEARLY ALL OF NH AND IMMEDIATELY ADJACENT ME...COINCIDING WITH SPC SWODY2. FARTHER NE...LOW CLOUDS...FOG...AND COOL TEMPS WILL REMAIN IN NELY ONSHORE FLOW N OF WARM FNT. COLD FNT WILL BE APPROACHING THE CWA TUE NGT...BUT WILL NOT CLEAR THE AREA UNTIL WED. THIS MEANS SHRA/TSRA WILL CONTINUE THRU WED NGT...THOUGH THE SEVERE THREAT WILL EVENTUALLY BE MITIGATED OVERNIGHT BY LOSS OF DAYTIME HEATING. && .LONG TERM /WEDNESDAY THROUGH MONDAY/... A COLD FRONT WILL BE CROSSING THE REGION EARLY WED...WITH THE GREATEST THREAT FOR A SHOWER EXPECTED DURING THE EARLY MORNING HOURS. A SECOND FRONT WILL BRING A CHC FOR A SHOWER OVER NRN AREAS ON THU...FOLLOWED BY SFC HIGH PRES FROM THE GTLKS THU NGT AND FRI. THIS WILL BRING A SHORT REPRIEVE FM THE WET CONDS AND THE BRIEF SHOT OF DRY WX TO NEW ENG. A RELATIVELY STG LOW PRES SYS FOR THIS TIME OF THE YEAR MOVES TOWARDS THE GTLKS ON SAT. AHEAD OF THIS SYSTEM...GUSTY SOUTHERLY WINDS WILL BE DEVELOPING. AREAS OF RA WILL CROSS THE REGION IN BANDS PROPAGATING FROM WEST TO EAST SAT NGT. THIS WILL NEED TO BE MONITORED AS SOME OF THIS RAIN MAY BE PARTICULARLY HEAVY AS MOISTR WILL BE TAPPED FROM THE MID ATLC REGION. THEREAFTER...THE UPPER LVL LOW PRES SYS WILL SLOWLY CROSS THE REGION THROUGH MON...BRINGING SLGTLY DRIER AIR TO THE REGION...HOWEVER A BRIEF PASSING SHOWER OR TWO CANNOT BE RULED OUT. VERY HIGH ASTRONOMICAL TIDES WILL NEED TO BE MONITORED OVER THE WEEKEND AND INTO EARLY NEXT WEEK AS WELL. && .AVIATION /02Z TUESDAY THROUGH SATURDAY/...
