AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAY ME 931 PM EDT MON APR 23 2007 .SHORT TERM /REST OF TONIGHT/... A RATHER IMPRESSIVE LINE OF SHOWERS AND THUNDERSTORMS HAS SET UP ACROSS NEW YORK THIS EVENING...GENERATING SOME SEVERE WEATHER. WINDS ALOFT ARE INDEED STRONG...WITH A 50-60 KT JET AT 850 MB. THIS LINE GENERATED ENOUGH OF A DOWNDRAFT TO BRING THIS DOWN TO THE SURFACE. HOWEVER...WITH DEW POINTS STILL IN THE 30S IN NEW HAMPSHIRE...AND OUR GYX 00Z SOUNDING VERY DRY...FEEL THIS LINE WILL FALL APART RAPIDLY AS IT ENTERS NEW HAMPSHIRE. LIGHTNING ACTIVITY ACTUALLY SUPPORTS HIS...WITH THE LINE GOING FROM MOSTLY NEGATIVE STRIKES...TO MAINLY POSITIVE STRIKES...INDICATING THE LINE IS WEAKENING. EVEN STILL...DO EXPECT SOME SHOWERS TO MAKE IT INTO THE MOUNTAINS. THE QUESTION FOR US IS...WILL ANY OF THE WINDS ALOFT MAKE IT DOWN TONIGHT. BUFKIT INDICATES SOME MIXING AFTER MIDNIGHT TONIGHT...WITH WINDS BECOMING MORE GUSTY IN NATURE. THE SHOWERS COULD ALSO AID MIXING...ALTHOUGH NO SEVERE WEATHER IS EXPECTED. WILL ALSO UPDATE ZONES TO RAISE OVERNIGHT LOWS...GIVEN THE GUSTY WINDS...EXPECT LITTLE RADIATIONAL COOLING TONIGHT. WILL ALSO ADD A MENTION OF WIND GUSTS TO THE ZONE AHEAD OF THE FRONTAL PASSAGE...AND SLIGHTLY EXPAND CHANCE POPS...ALTHOUGH STILL FEEL MOST ALONG THE COAST WILL STAY DRY. && .MARINE... WILL BUMP UP WINDS TO JUST BELOW GALE THRESHOLD. EXPECT A FEW 35-40 KT GUSTS JUST AHEAD OF THE FRONT...BUT THESE WILL BE ISOLATED...GIVEN THE STABLE MARITIME ENVIRONMENT. && .FIRE WEATHER... ALLOWED THE RED FLAG WARNING TO EXPIRE. RELATIVE HUMIDITIES DROPPED TO 15 TO 20 PERCENT IN ALL BUT THE MAINE COASTLINE...WITH WINDS GUSTING OVER 25 MPH AT MOST LOCATIONS. EXPECT DRY AND WINDY CONDITIONS TOMORROW AS WELL...BUT HUMIDITIES SHOULD BE A TAD HIGHER...AND WINDS A TAD LESS. ALSO COULD SEE SOME RAIN IN THE MOUNTAINS TONIGHT. WILL LEAVE THE RED FLAG DECISION UP TO THE MID NIGHT SHIFT. && .HYDROLOGY... SWIFT RIVER AT ROXBURY CRESTING ABOUT A TENTH OF A FOOT BELOW FLOOD STAGE...BUT WILL LET THIS WARNING DROP...AS THE SNOW MELT RUNOFF SHOULD/VE MAXED OUT BASED ON OBS FROM THE PAST SEVERAL DAYS. WILL CONTINUE THE WARNING AT SKOWHEGAN AND PITTSFIELD. SKOWHEGAN IS WAVERING JUST BELOW FLOOD STAGE...BUT STILL EXPECT IT TO RISE OVERNIGHT AS WATER UPSTREAM REACHES THE GAGE. && .PREV DISCUSSION... /ISSUED 222 PM EDT MON APR 23 2007/ SHORT TERM /TONIGHT THROUGH TUESDAY/... THE WARM SOUTHWEST FLOW WITH CLEAR CONDITIONS AHEAD OF AN APPROACHING COLD FRONT WILL RAPIDLY GIVE WAY TO CLOUDS AND SCATTERED SHOWERS IN THE MOUNTAINS AND FOOTHILLS AS WELL AS SOME INTERIOR PORTIONS LATER THIS EVENING AND INTO THE EARLY MORNING HOURS. ALONG THE COAST CONDITIONS SHOULD REMAIN DRY. MODELS HAVE CONDITIONS RAPIDLY CLEARING AFTER 09Z AND BY 12Z A WEST FLOW WITH DRY CONDITIONS AND CLEAR SKIES RETURN. TEMPERATURES WILL BE MILD TONIGHT DUE TO CLOUDS AND MIXING DUE TO THE COLD FRONT MOVING THROUGH THE AREA. TUESDAY SHOULD BE MOSUNNY AND COOLER BUT STILL ABOVE NORMAL. DOWNSLOPE WINDS SHOULD ALSO HELP KEEP ANY FAIR WEATHER CLOUD DEVELOPMENT TO A MINIMUM. LONG TERM /TUESDAY NIGHT THROUGH MONDAY/... AT THE START OF THE PERIOD CWA WILL BE SITTING BENEATH 500MB ZONAL FLOW ON THE THE PERIPHERY OF BROAD TROUGH OVER ERN CANADA. WEAK WAVES WILL MOVE THRU...FIRST ONE OF WHICH WILL OCCUR LATED WED INTO WED NIGHT. BOTH NAM AND GFS NOW SUGGEST THAT THIS SYSTEM STAYS FAR ENOUGH S THAT IT WILL ONLY PROVIDE SOME CLOUDS TO SRN ZONES...WITH AN OUTSIDE SHOT THAT SOME SHRA MAKE IT INTO FAR SRN ZONES. THIS WILL BE FOLLOWED BY RIDGING ON THU...BEFORE A CLOSED 500MB LOW TRACKS OUT OF THE PLAINS AND INTO THE GREAT LAKES...WHICH COULD BRING SOME RA INTO THE CWA FOR THE WEEKEND...ALTHOUGH CONFIDENCE IN MODEL HANDLING OF CLOSED LOWS THAT FAR OUT IS WEAK. -CEMPA AVIATION /18Z-18Z/... VFR CONDITIONS INTO THIS EVENING BEFORE A COLD FRONT MOVES THROUGH WITH SCATTERED SHOWERS POSSIBLY LOWERING CONDITIONS BRIEFLY TO MVFR IN A FEW INLAND SPOTS AFT 03Z. AFTER 09Z THE FRONT MOVES OFF THE COAST AND WINDS SHIFT TO WEST ALLOWING CLEAR CONDITIONS TO RETURN BY 12Z FROM WEST TO EAST. MARINE... WILL CONTINUE THE SCA THROUGH TONIGHT SINCE WINDS AND SEAS WILL SUPPORT THE CRITERIA AHEAD OF THE COLD FRONT. BY MORNING WINDS WILL SHIFT TO THE WEST TO NORTHWEST BUT WILL NOT BE AS STRONG. ALSO SEAS BY MORNING SHOULD GET KNOCKED DOWN BY THE DEVELOPING OFFSHORE FLOW WHICH WILL CONTINUE THROUGH TUESDAY. FIRE WEATHER... WILL CONTINUE THE RED FLAG WARNING THROUGH THIS EVENING SINCE THE COMBINED WARM TEMPS..LOW RH VALUES..AND BREEZY CONDITIONS ALL WARRANT THE WARNING TIL SUNSET. HYDROLOGY... KEEPING AN EYE ON THE KENNEBEC AT SKOWHEGAN...AS WELL AS OTHER RIVERS IN THE NORTH...AS SNOWMELT HAS INCREASED DURING TODAY. THE SNOWMELT WILL ALSO SLOW THE FALL OF THE SEBASTICOOK...WHICH WILL REMAIN ABOVE FLOOD STAGE THROUGH TONIGHT. && .GYX WATCHES/WARNINGS/ADVISORIES... ME...NONE. NH...NONE. MARINE...SMALL CRAFT ADVISORY UNTIL 8 AM EDT TUESDAY FOR ANZ150. && UPDATE: APFFEL
