Area forecast discussion, Jun 4, 8:27 AM EST, 2 hours 23 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BUFFALO NY 927 AM EDT SAT JUN 4 2011 .SYNOPSIS... A WARM FRONT WILL APPROACH FROM THE SOUTHWEST TODAY...BRINGING MID AND HIGH LEVEL CLOUDS. SCATTERED SHOWERS AND THUNDERSTORMS WILL DEVELOP ALONG THE FRONTAL ZONE. A COLD FRONT WILL QUICKLY FOLLOW TONIGHT WITH ANOTHER CHANCE FOR SHOWERS AND THUNDERSTORMS. && .NEAR TERM /THROUGH TONIGHT/... 920 AM UPDATE...ALL EYES ON LARGE MCS APPROACHING FROM THE NORTHWEST AT MID MORNING. CENTER OF ACTIVITY MOVING DOWN OFF LK HURON AND GEORGIAN BAY INTO SRN ONTARIO...WITH LEADING EDGE OF SHOWERS INTO TORONTO AREA ATTM. HRRR INITIALIZING FAIRLY WELL AND SHOWS THIS FEATURE DIVING SSE AND AFFECTING AREAS FROM BUF TO CHAUT COUNTY...BUT WILL RELY MORE ON ACTUAL IR SATELLITE... RADAR...AND LIGHTNING TRENDS FOR THE NEXT FEW HOURS. THESE SHOW CLOUD TOPS BEGINNING TO WARM AND MOVEMENT TURNING A BIT MORE SOUTHERLY...MORE LIKE 340-350 FOR CENTER OF FEATURE. THIS WOULD TAKE IT DOWN ACROSS EASTERN LK ERIE AND CHAUT COUNTY...BUT OUTER EDGE WOULD STILL WET DOWN BUF-NIAG REGION IN THE 11 AM TO 1 PM TIME FRAME. DID MAJOR UPDATE TO GRIDS TO ACCOUNT FOR THIS...WITH CATEG POPS FROM BUF WEST AND SOUTHWEST...BUT SHARP GRADIENT TO SLGT CHC GEN VALLEY EAST WHICH WILL MISS THIS SYSTEM COMPLETELY. BUF 12Z RAOB VERY DRY SO THIS WILL ALSO HELP TO WEAKEN SYSTEM AS IT REACHES OUR AREA...BUT IT IS TOO CLOSE ALREADY SO WE WILL GET SOME RAIN. EXPECT THE MCS TO WEAKEN THROUGH MIDDAY AND EARLY AFTERNOON AS IT REACHES CHAUT CO AND NW PA/NE OHIO...BUT WILL THEN NEED TO KEEP AN EYE ON REDEVELOPMENT LATER THIS AFT/EARLY EVE AS WARM SECTOR TRIES TO PUSH EAST FROM MICH AHEAD OF THE COLD FRONT LATER TONIGHT. OF CONCERN IS TONGUE OF 70+ DEW PTS OVER CHICAGOLAND AND MKE WHICH WILL QUICKLY ADVECT ACROSS SRN MICH AND SW ONTARIO THIS AFTERNOON. WILL FOCUS MORE ON THIS IN LATER PACKAGE. ADJUSTED TEMP GRIDS DOWNWARD IN FAR WEST AND INCREASED QPF GRIDS. SHOULD STILL SEE SOME PARTIAL CLEARING BUF AREA EARLY-MID AFTERNOON AFTER THIS FEATURE WORKS THROUGH. RELEVANT PORTION OF PREV DISC FOLLOWS... A SECOND CONVECTIVE POTENTIAL WILL EXIST LATER IN THE DAY AND EARLY TONIGHT AS THE COLD FRONT ARRIVES. MODEL SOUNDINGS SUGGESTING MLCAPES FROM 1500-2000 J/KG BY EARLY EVENING AS THE FRONT DROPS DOWN ACROSS THE AREA. THE POTENTIAL EXISTS FOR SEVERE WEATHER...WITH UNIDIRECTIONAL SHEAR PROFILES SUPPORTING LINEAR SEGMENTS AND DAMAGING WINDS AS THE MAIN THREAT...PRIMARILY ALONG THE SOUTHERN TIER. LARGE HAIL NOT OUT OF THE QUESTION GIVEN POTENTIAL STRENGTH OF UPDRAFTS. BEHIND THE COLD FRONT A BUBBLE HIGH WILL SETTLE IN WITH GRADUAL DRYING OVERNIGHT TONIGHT. && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... THE WEAK COLD FRONT/SURFACE TROUGH THAT WILL BE IN PLACE OVER CENTRAL NEW YORK SUNDAY MORNING WILL MOVE INTO EASTERN NEW YORK DURING THE AFTERNOON. WEAK CONVERGENCE IN THE VICINITY OF THIS BOUNDARY AND DAYTIME HEATING WILL GENERATE A FEW SHOWERS...BUT MOST OF THE PCPN SHOULD STAY EAST OF OUR CWA. OTHERWISE...EXPECT A WEST TO EAST INCREASE IN SUNSHINE DURING THE DAY AS DRIER AIR WORKS EAST ACROSS THE AREA. A WEAK SURFACE RIDGE WILL THEN SETTLE ACROSS THE LOWER LAKES MONDAY AND MONDAY NIGHT AND BRING MORE DRY WEATHER AND SLIGHTLY ABOVE AVERAGE TEMPERATURES. && .LONG TERM /TUESDAY THROUGH FRIDAY/... DRY AND WARM WEATHER WILL CONTINUE TUESDAY AND WEDNESDAY WITH WEAK HIGH PRESSURE STILL IN PLACE OVER THE LOWER LAKES AND OHIO VALLEY. THE CHANCES FOR A FEW SHOWERS AND THUNDERSTORMS WILL GO UP THURSDAY AS INCREASING LOW LEVEL MOISTURE INTERACTS WITH A COLD FRONT THAT IS FORECAST TO APPROACH LAKE ONTARIO. WITH 850 MB TEMPERATURES EXPECTED TO AVERAGE AROUND 18C...CORRESPONDING SURFACE TEMPERATURES MAY WARM WELL INTO THE 80S AWAY FROM LAKE INFLUENCES. OF COURSE...CLOUD COVER AND THE POTENTIAL FOR CONVECTION IN THE VICINITY OF A PRE-FRONTAL TROUGH WILL IMPACT TEMPERATURES. EXPECT A FEW MORE SHOWERS AND THUNDERSTORMS TO LINGER THURSDAY NIGHT AND FRIDAY AS THE AFOREMENTIONED COLD FRONT DROPS SOUTH ACROSS NEW YORK STATE. && .AVIATION /13Z SATURDAY THROUGH WEDNESDAY/... CONVECTIVE COMPLEX MOVING SOUTHEAST FROM LK HURON WILL AFFECT THE FAR WESTERN TERMINALS BETWEEN 15Z AND 19Z TODAY. WILL GO WITH "VCTS" AT KBUF/KIAG AND TSRA AT KJHW WHERE IT IS MORE CERTAIN. NO PROBLEMS FURTHER EAST TODAY. MVFR CONDITIONS WHERE CONVECTION DEVELOPS. MORE CONVECTION POSSIBLE THIS EVENING AHEAD OF A COLD FRONT. OUTLOOK... SUNDAY THROUGH WEDNESDAY...MAINLY VFR. && .MARINE... HIGH PRESSURE WILL SLOWLY MOVE SOUTHEAST ACROSS THE EASTERN GREAT LAKES REGION WHILE A WARM FRONT APPROACHES FROM THE SOUTHWEST. LOCALLY MARINE INFLUENCES WILL DOMINATE THE WIND AND WAVE CONDITIONS TODAY. A COLD FRONT WILL MOVE THROUGH TONIGHT AND BRING LIGHT NORTHWESTERLY WINDS TO THE LAKES. THERE WILL BE A CHANCE FOR SHOWERS AND THUNDERSTORMS TODAY AND TONIGHT. && .BUF WATCHES/WARNINGS/ADVISORIES... NY...NONE.
