NWS Gray, ME wrote its last area forecast discussion before the first event at Jun 25, 2:20 PM EST, 55 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAY ME 320 PM EDT TUE JUN 25 2013 .SYNOPSIS... SCATTERED AND POTENTIALLY SEVER THUNDERSTORMS ARE POSSIBLE INTO THIS EVENING AS AN UPPER LEVEL DISTURBANCE MOVES ACROSS THE HOT AND HUMID AIR MASS. AN UPPER LEVEL TROUGH WILL DEVELOP OVER THE GREAT LAKES ON THURSDAY AND REMAIN NEARLY STATIONARY THROUGH EARLY NEXT WEEK. AS A RESULT... SEVERAL ROUNDS OF RAIN WILL BEGIN TO AFFECT NEW ENGLAND FROM THURSDAY EVENING THROUGH THE WEEKEND. && .NEAR TERM /THROUGH TONIGHT/... MAIN ISSUE WILL BE POTENTIAL SEVERE STORMS THIS AFTERNOON INTO EARLY EVENING. INSTABILITY IS THERE...BUT SHEAR AND ORGANIZED FORCING ARE CURRENTLY MINIMAL. MODELS DO SUGGEST STORMS GET BETTER ORGANIZED OVER THE NEXT SEVERAL HOURS...SO SEVERE POTENTIAL WILL REMAIN THROUGH ABOUT 00Z. EXPECTING LITTLE CHANGE IN AIR MASS OVERNIGHT...AND ANY CLEARING THAT MAY OCCUR WILL LEAD TO FOG AND LOW STRATUS. LOWS ONCE AGAIN WILL BE LIMITED TO THE 60S...WARMEST NEAR THE COAST AND IN SRN NH. && .SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/... FRONTAL BOUNDARY...MAINLY REFLECTING WIND SHIFT AND COOLER TEMPS...WILL DROP SE ACROSS THE CWA DURING WED. THIS WILL SET OFF SHRA AND TSRA ACROSS THE CWA DURING THE DAY. FAR SRN ZONES SHOULD REMAIN ON THE HOT AND HUMID SIDE AGAIN...BUT TO THE N AND E COOLER AIR WILL MOVE IN BEHIND THE FRONT. LOOKS FOR STRATUS AND FOG TO DEVELOP BEHIND THE FRONT WED NIGHT. LOWS MAY END UP A FEW DEGREES COOLER THAN PREVIOUS NIGHTS. && .LONG TERM /THURSDAY THROUGH TUESDAY/... SURFACE HIGH PRESSURE IS EXPECTED TO BE OVER THE GULF OF SAINT LAWRENCE AREA ON THURSDAY WITH AN UPPER LEVEL TROUGH DEVELOPING OVER THE GREAT LAKES. SURFACE FLOW WILL BE EASTERLY OVER NEW ENGLAND... AND AS A RESULT EXPECT COOL AND CLOUDY WEATHER ON THURSDAY WITH POSSIBLE FOG AND DRIZZLE ESPECIALLY IN THE FOOTHILLS AND MOUNTAINS. AS THE UPPER TROUGH DIGS TO THE WEST... SURFACE LOW PRESSURE WILL FORM OVER THE UPPER OHIO RIVER VALLEY INTO WESTERN PENNSYLVANIA. MORE HIGH AND MID LEVEL CLOUD COVER WILL SPREAD INTO THE AREA IN ADVANCE OF THE LOW. EVENTUALLY RAIN WILL SPREAD NORTH INTO THE AREA LATER IN THE DAY AS A WARM FRONT SHARPENS OVER SOUTHERN NEW ENGLAND. THE WARM FRONT WILL LIFT NORTH INTO NEW HAMPSHIRE AND WESTERN MAINE THURSDAY NIGHT... SPREADING RAIN OVER THE ENTIRE REGION. TOTAL RAINFALL AMOUNTS OF 1 TO 2 INCHES ARE POSSIBLE. GFS AND ECMWF DIFFER SOMEWHAT ON HOW TO HANDLE THE SURFACE LOW LATER THIS WEEK. GFS DEVELOPS A STRONGER LOW WITH SHARPER FRONTS. AS A RESULT... IT PUSHES THE LOW OFF TO THE NORTH NORTHEAST WITH A COLD FRONT SWEEPING IN FROM THE WEST ON FRIDAY... CUTTING OFF THE SIGNIFICANT PRECIPITATION. HOWEVER... THE ECMWF KEEPS THE LOW MUCH WEAKER AND HANGS IT FURTHER BACK CLOSER TO THE UPPER TROUGH. THIS KEEPS PRECIPITATION IN OUR AREA THROUGH FRIDAY AND SATURDAY. REGARDLESS... EVEN WITH THE GFS SOLUTION... CONVECTION WILL BE POSSIBLE IN THE MOIST AND BROADLY DIVERGENT FLOW PATTERN TO THE EAST OF THE UPPER TROUGH... ESPECIALLY IN THE AFTERNOONS. KEPT POPS AT LEAST IN THE CHANCE RANGE THROUGH EARLY NEXT WEEK AS THE TROUGH STAYS TO OUR WEST AND KEEPS US IN THE SOUTHERLY FLOW. TEMPERATURE FORECAST IS A BIT UNCERTAIN FROM SATURDAY ONWARD. SOUTHERLY FLOW WOULD GENERALLY PUT US IN A WARM AIR MASS... BUT THE ONSHORE FLOW AND SHOWERS WOULD KEEP TEMPERATURES DOWN. IF THE DRIER GFS SOLUTION BECOMES REALITY... THEN THERE WILL BE MORE SUNNY BREAKS AND HIGHS WILL REACH THE 80S. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... SHORT TERM...TSRA CONTAINING WIND GUSTS TO 50+ KTS AND LARGE POSSIBLE THROUGH ABOUT 00Z. THEN IFR OR LOWER LOW CLOUDS AND FOG DEVELOP...ESPECIALLY ALONG THE COAST OVER NIGHT. A LITTLE IMPROVEMENT IS POSSIBLE DURING THE DAY INLAND...BUT IFR OR LOWER RETURNS WED NIGHT. LONG TERM...EXPECT IFR OR LOWER CONDITIONS ON THURSDAY AND ESPECIALLY THURSDAY NIGHT INTO FRIDAY. CONDITIONS MAY VARY FROM VFR TO IFR IN SHOWERS THIS WEEKEND. && .MARINE... SHORT TERM...WINDS SEAS QUIET THROUGH WED NIGHT. SEVERE TSRA POSSIBLE LATE TODAY INTO EARLY EVENING. LONG TERM...SOUTHERLY FLOW WILL INCREASE AHEAD OF LOW PRESSURE ON THURSDAY INTO FRIDAY. EXPECT WINDS IN THE 25 TO 30 KT RANGE WITH SEAS INCREASING ESPECIALLY OVER THE EASTERN WATERS. CONDITIONS IMPROVE THIS WEEKEND. && .GYX WATCHES/WARNINGS/ADVISORIES... ME...NONE. NH...NONE. MARINE...NONE. && SYNOPSIS... NEAR TERM...CEMPA SHORT TERM...CEMPA LONG TERM...KIMBLE AVIATION...
