NWS Binghamton, NY wrote its last area forecast discussion before the first event at Apr 19, 6:30 PM EST, 3 hours earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 730 PM EDT THU APR 19 2007 .AVIATION /00Z-24Z/... SOME SCT CLDS THIS EVE OTRW MAINLY CLR SKIES OVRNGT AND INTO FRI. STRONG DRY AIR ADVECTING INTO THE REGION SHD PRECLUDE FOG FORMATION OVR NGT. GNRLY WINDS WILL BE LGT AND HAVE LTL EFFECT ON OPS. && .PREV DISCUSSION... /ISSUED 209 PM EDT THU APR 19 2007/ SHORT TERM /TONIGHT THROUGH SUNDAY/... GLOBAL MODELS CONTINUE TO BE IN GOOD AGREEMENT THROUGH SUNDAY TAKING THE OMEGA BLOCK THAT IS OVER THE CENTRAL PORTION OF THE NORTH AMERICAN CONTINENT AND PUSHING IT EASTWARD. AT THE SAME TIME...THE RIDGE ASSOCIATED WITH THIS BLOCK WILL FLATTEN. WE WILL REMAIN EAST OF THE MID LEVEL/SURFACE RIDGE AXIS THROUGH SATURDAY NIGHT...WITH DRY NORTHERLY FLOW OVER THE CWA. MINOR AMOUNTS OF CLOUD COVER THROUGH THE PERIOD WILL BE GOVERNED BY SOME WEAK MID LEVEL IMPULSES THAT WILL ROTATE THROUGH THE AREA. WITH THE SFC RIDGE NEARING THE AREA BY THE END OF THE WEEKEND...EXPECT TEMPS TO MOVE WELL /10F/ ABOVE SEASONAL NORMS BY THE SATURDAY-SUNDAY TIMEFRAME. THIS EVENING...THE RUC AND NAM PROFILES SUGGEST THE ARRIVAL OF ONE LAST WEAK SHORTWAVE FROM THE EAST AROUND OR JUST AFTER 00Z TONIGHT. NAM/RUC RH PROGS SHOW A LITTLE BIT IN THE WAY OF MID LEVEL MOISTURE ASSOCIATED WITH THIS WAVE...MOSTLY IMPACTING OUR SOUTHEASTERN ZONES. WITH 500 HEIGHTS BUILDING THROUGH THE EVENING...CANT SEE THIS WAVE DOING ANYTHING MORE THAN DELAYING THE TRANSITION FROM PCLOUDY TO MCLEAR OVER THE SOUTHERN ZONES THIS EVENING. AFTER THIS WAVE DEPARTS...EXPECT A PROLONGED PERIOD OF DRY WEATHER WITH TEMPERATURES CONTINUING TO CLIMB. MODELS BRING A PRETTY STRONG SHORT WAVE RIDGE THROUGH THE AREA ON FRIDAY...ALLOWING FOR A WONDERFUL DAY. BUFKIT PROFILES ARE QUITE DRY WITH A STRONG SUBSIDENCE INVERSION. GOOD MIXING TO 850 WILL TAP ANY WINDS IN THE LOWER LEVELS AND BRING THEM TO THE SURFACE...BUT THE GRADIENT WONT BE PARTICULARLY IMPRESSIVE...SO NOTHING MORE THAN 20-25MPH GUSTS ARE EXPECTED. T850 RANGES FROM +4-6C IN THE GUIDANCE...WHICH WOULD GIVE HIGHS IN THE L/MID 60S...AND WELL LEAN TOWARDS THE WARMER END BASED ON HOW THE MODELS HAVE BEEN PLAYING CATCH UP WITH THE TEMPS OVER THE PAST FEW DAYS. IT APPEARS WE WILL FINALLY GET A CHANCE TO DRY OUT SOME WITH DEW POINTS REMAINING IN THE U20S/L30S THROUGHOUT THE DAY. TONIGHT...MODELS DROP THE DEWPOINTS RAPIDLY WITH OVER-LAND NORTHEASTERLY FLOW. UPSTREAM OBS FROM OUR CANADIAN NEIGHBORS AND EVEN THOSE OVER NEW ENGLAND INDICATE DEWPOINTS DROPPING INTO THE TEENS. THINK THIS STRONG LLEVEL DRYING WILL HOLD OFF UNTIL OVERNIGHT TONIGHT. THIS SHOULD ALLOW TEMPS TO FALL NICELY TONIGHT...PROBABLY COOLER THAN OVER THE PAST FEW NIGHTS. WILL GENERALLY FOLLOW MET GUIDANCE. THESE DRY READINGS...ALONG WITH A LITTLE BIT OF WIND SHOULD KEEP FOG FROM BEING A PROBLEM. THE DRY WEATHER CONTINUES INTO SATURDAY WITH LITTLE CHANGE. RH PROGS SHOW A LITTLE BIT IN THE WAY OF UPPER LEVEL MOISTENING IN THE AFTERNOON AS A WEAK SHORT WAVE ROTATES TOWARDS THE AREA IN THE NORTHWEST FLOW ALOFT. HOWEVER...THE DAY SHOULD BE SUNNY/MSUNNY AND WITH T850 BETWEEN 5-6C HIGHS AROUND U60S TO AROUND 70 LOOK GOOD. ALTHOUGH DEEP MIXING IS AGAIN EXPECTED...WEAKER GRADIENTS WILL LESSEN THE WINDS EVEN MORE...15MPH OR LESS EVEN IN GUSTS. LLEVEL RHS WILL LIKELY BE A LITTLE HIGHER THAN ON FRIDAY AS BOUNDARY LAYER WIND TRAJECTORIES TAKE MORE OF A TRACK OVER THE LAKES. THIS INCREASED LLEVEL MOISTURE SHOULD HELP KEEP LOWS SATURDAY NIGHT A LITTLE WARMER THAN ON FRIDAY NIGHT...PROBABLY JUST ABOVE FREEZING RATHER THAN AT/JUST BELOW. A LOW PRESSURE SYSTEM WILL MOVE EAST SOUTH OF HUDSON BAY ON SUNDAY AS THE EAST COAST RIDGE BEGINS TO FLATTEN. ALTHOUGH WELL NORTH OF THE CWA...SOME UPPER LEVEL CLOUDINESS MAY FILTER IN FROM THE NORTH. HOWEVER...THE DAY WILL STILL TURN OUT MSUNNY. WITH T850 REACHING 6-7C...U60S/L70S ARE LIKELY FOR HIGHS ACROSS THE CWA. WINDS WILL REMAIN QUITE LIGHT AS THE CREST OF THE SURFACE RIDGE MOVES OVER THE AREA. LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... NEXT WEEK WILL START OFF WITH A CONTINUATION OF DRY MILD WEATHER. BY TUESDAY...A COLD FRONT IS EXPECTED TO MOVE ACROSS FROM THE NORTHWEST...ACCOMPANIED BY SOME SHOWERS. AT THIS POINT...THE FRONT LOOKS AS THOUGH IT WILL BE PROGRESSIVE ENOUGH...SO THAT DRIER AND SOMEWHAT COOLER WEATHER SHOULD RETURN FOR WEDNESDAY AND THURSDAY. HYDROLOGY... BAINBRIDGE AND CONKLIN STILL THE PRIMARY SITES OF CONCERN WITH CONKLIN JUST ABOVE FS AND BAINBRIDGE VERY NEAR IT. RIVERS CONTINUE TO BE FED BY SNOWMELT...BUT THIS WILL COME TO AN END SOON. WAVERLY ALSO FORECAST TO COME CLOSE TO FS TOMORROW. HAVE KEPT WARNINGS AS THE ARE ATTM...BUT EXPECT RIVERS TO BEGIN TO FALL ESPECIALLY AS WE MOVE INTO TOMORROW AS THE REMAINING SNOWPACK IS LOST AND WE SEE AN EXTENDED DRY PERIOD. AGAIN...ONLY VERY MINOR FLOODING IS EXPECTED. && .BGM WATCHES/WARNINGS/ADVISORIES... NY...NONE. PA...NONE. && AVIATION...DGM
