NWS Buffalo, NY wrote its last area forecast discussion before the first event at May 27, 6:57 PM EST, 5 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BUFFALO NY 757 PM EDT WED MAY 27 2015 .SYNOPSIS... A WEAK COLD FRONT WILL MOVE ACROSS THE REGION EARLY TONIGHT. HIGH PRESSURE WILL MOVE IN BEHIND THE FRONT THURSDAY...THEN MOVE OFF THE NEW ENGLAND COAST FRIDAY. A SHARP COLD FRONT IS EXPECTED TO PUSH THROUGH THE REGION OVER THE WEEKEND. && .NEAR TERM /THROUGH THURSDAY/... A MID LEVEL TROUGH WILL BE SWINGING THROUGH THE GREAT LAKES TONIGHT WHILE A SURFACE LOW OVER ONTARIO PULLS A COLD FRONT ACROSS WESTERN NEW YORK LATE TONIGHT. THIS WILL FINALLY PROVIDE SOME SURFACE BASED FORCING TO A WARM AND HUMID AIRMASS THATS BEEN IN PLACE FOR THE PAST SEVERAL DAYS. RADAR IMAGERY THIS EVENING SHOWING AN AREA OF SHOWERS AND SCATTERED STORMS CROSSING WESTERN NY ALONG A PRE-FRONTAL TROUGH AND JUST AHEAD OF A MID LEVEL TROUGH MOVING THROUGH THE CENTRAL LAKES. LARGE SCALE ASCENT AHEAD OF THE MID LEVEL TROUGH AND LOW LEVEL CONVERGENCE ALONG THE PRE-FRONTAL TROUGH WILL CONTINUE TO SUPPORT SCATTERED CONVECTION THROUGH THE EARLY OVERNIGHT AS THE PRE-FRONTAL TROUGH AND COMPOSITE OUTFLOW BOUNDARY MOVES EAST ACROSS THE AREA. THE ACTUAL SURFACE COLD FRONT IS LAGGING BEHIND ACROSS THE CENTRAL LAKES...AND WILL CROSS THE AREA LATE TONIGHT POSSIBLY PRODUCING A FEW MORE SHOWERS AND SCATTERED THUNDERSTORMS. A FEW OF THE STRONGER STORMS MAY PRODUCE GUSTY WINDS AND HEAVY RAINFALL THROUGH THIS EVENING. SBCAPE IS AROUND 1000J/KG WITH 0-6KM SHEAR ON THE ORDER OF 30-35 KNOTS...BOTH VERY MARGINAL TO SUPPORT ANY SEVERE POTENTIAL. IN ADDITION...SO FAR THE COMPOSITE OUTFLOW BOUNDARY AHEAD OF THE AREA OF CONVECTION WHICH HAS LIMITED INTENSITY. NEW STORMS DEVELOPING OVER THE GENESEE VALLEY ARE NEAR THE LEADING EDGE OF THE OUTFLOW...AND WILL HAVE SOME ISOLATED SEVERE RISK IN THE NEAR TERM. OVERNIGHT BOUNDARY LAYER STABILIZATION WILL END ANY SEVERE RISK. ONCE THE FRONT PUSHES THROUGH THE THREAT FOR CONVECTION WILL DIMINISH. COOLER AND DRIER AIR WILL MOVE IN OVERNIGHT WITH LOWS IN THE MID 50S TO LOWER 60S. RISING HEIGHTS WILL CONTINUE TO PUSH ACROSS THE GREAT LAKES REGION DURING THE DAY ON THURSDAY. PLENTY OF DRY AIR AND SUBSIDENCE WILL PROVIDE A FAIR WEATHER DAY. HIGH MAINLY IN THE LOWER TO MID 70S...BUT LIKELY REMAINING THE THE UPPER 60S ACROSS THE NORTH COUNTRY. && .SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/... A PROGRESSIVE FLOW FOUND OVER NORTH AMERICA WILL OFFER TWO FAIRLY SIGNIFICANT COLD FRONTAL PASSAGES OVER THE GREAT LAKES DURING THIS PERIOD....BUT THE BULK OF THE TIME WILL BE DOMINATED BY A STRONG EAST COAST RIDGE. THIS WILL TRANSLATE INTO MAINLY DRY...UNEVENTFUL WEATHER. THE GOOD NEWS FOR AGRICULTURALISTS IS THAT THE STRETCH OF DRY WEATHER WILL LIKELY END WITH A 'WET' FRONTAL PASSAGE AS THIS TIME FRAME COMES TO A CLOSE. A STRONG SHORTWAVE CROSSING THE UPPER GREAT LAKES TODAY WILL DRIVE A COLD FRONT ACROSS OUR REGION LATE TONIGHT AND EARLY THURSDAY. THE MAIN FRONT SHOULD BE THROUGH MOST OF OUR FORECAST AREA BY DAYBREAK WITH MID LEVEL DRYING ALREADY BECOMING ESTABLISHED OVER THE WESTERN COUNTIES. A SECONDARY FRONTAL BOUNDARY WILL SWEEP ACROSS THE NORTH COUNTRY BY MIDDAY THOUGH...AND THIS SHOULD DELAY THE ONSET OF FAIR WEATHER FOR THAT AREA BY SOME 3 TO 6 HOURS. OTHERWISE...HIGH PRESSURE CENTERED IN THE VCNTY OF JAMES BAY WILL NOSE SOUTH ACROSS THE LOWER GREAT LAKES DURING THE COURSE OF THE DAY....WITH SUBSIDENCE AND CONTINUED DRYING LEADING TO INCREASING AMOUNTS OF SUNSHINE. IT WILL BE COOLER AND NOTICEABLY LESS HUMID AS WELL...AS DEWPOINTS THAT HAD BEEN IN THE 60S WILL DROP BACK THROUGH THE 50S. AFTERNOON MAX TEMPS WILL GENERALLY BE IN THE 70S. THURSDAY NIGHT WILL FEATURE MOONLIT SKIES AS A BURGEONING H5 RIDGE WILL SLIDE ACROSS THE LOWER GREAT LAKES. IT WILL BE A COMFORTABLE NIGHT WITH TEMPERATURES GENERALLY SETTLING INTO THE 50S. SITES IN THE COOLER SRN TIER VALLEYS AND IN THE FOOTHILLS OF THE ADIRONDACKS COULD CONCEIVABLY EXPERIENCE MINS IN THE UPPER 40S. WARMER WEATHER WILL RETURN TO OUR FORECAST AREA ON FRIDAY...AS A STRENGTHENING RIDGE WILL TAKE SHAPE ALONG THE EAST COAST. THE DEEPENING SOUTHERLY FLOW FOUND BETWEEN THE ASSOCIATED OFFSHORE SFC HIGH AND A COLD FRONT OVER THE UPPER GREAT LAKES WILL PUMP H85 TEMPS BACK INTO THE MID TEENS CELSIUS...WHICH WILL EASILY SUPPORT AFTERNOON MAX TEMPS IN THE MID 80S FOR ALL BUT THE LAKE SHORES AND HIGHER TERRAIN. THE ONLY FLY ION THE OINTMENT FOR FRIDAY WILL BE THE POTENTIAL FOR A LATE AFTERNOON THUNDERSTORM IN THE VCNTY OF A LAKE BREEZE BOUNDARY OVER THE SRN TIER. FROM THIS VANTAGE POINT THOUGH...THE AIRMASS LOOKS LIKE IT WILL STILL BE DRY ENOUGH TO KEEP THIS THREAT FROM BEING TOO WIDESPREAD. AFTER A VERY MILD AND UNEVENTFUL FRIDAY NIGHT WHEN MIN TEMPERATURES WILL HOLD IN THE MID TO UPPER 60S...IT WILL LIKELY TURN QUITE UNSETTLED FOR SATURDAY. A SHARP COLD FRONTAL BOUNDARY STRETCHING FROM GEORGIAN BAY AND LOWER MICHIGAN TO ABOUT CHICAGO AT DAYBREAK SATURDAY WILL SLOWLY PRESS SOUTHEAST TO LAKES ERIE AND ONTARIO BY EVENING. A WARM UNSTABLE AIRMASS IN ADVANCE OF THE FRONT WILL SUPPORT THE DEVELOPMENT OF NUMEROUS SHOWERS AND THUNDERSTORMS BY AFTERNOON...WITH A STRONG 130KT H25 JET OVER QUEBEC REINFORCING DEEP SYNOPTIC LIFT THROUGH THE ENTIRE BOUNDARY LAYER. THIS SHOULD RESULT IN SOME AREAS OF SIGNIFICANT DOWNPOURS WITH RAINFALL AMOUNTS OF OVER AN INCH POSSIBLE. HIGH PRESSURE OVER ONTARIO WILL SLOWLY PUSH THE FRONT ACROSS WESTERN AND NORTH CENTRAL NEW YORK SATURDAY NIGHT. THE ANABATIC NATURE OF THE SLOW MOVING COLD FRONT WILL LIKELY KEEP SHOWERS IN PLACE SATURDAY NIGHT WHEN ANOTHER HALF INCH OR MORE OF RAIN COULD FALL. THIS FRONTAL PASSAGE CERTAINLY HAS THE POTENTIAL TO PRODUCE THE MOST WIDESPREAD SOAKING RAINFALL IN QUITE SOME TIME. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... ANOMALOUSLY STRONG HIGH PRESSURE WILL DRIFT ACROSS EASTERN CANADA SUNDAY AND MONDAY...AND THIS WILL SHOVE A MOISTURE RICH COLD FRONT FURTHER SOUTH ACROSS THE MID ATLANTIC STATES. LEFTOVER SHOWERS OVER MUCH OF OUR REGION ON SUNDAY WILL FINALLY COME TO AN END AS A RESULT...BUT A FAIR AMOUNT OF CLOUDS WILL LIKELY PERSIST. THIS WILL ESPECIALLY BE THE CASE CLOSER TO THE PENNSYLVANIA BORDER. H85 TEMPS IN THE WAKE OF THE FRONT ARE FORECAST TO BE IN THE UPPER SINGLE DIGITS (CELSIUS)...SO SUNDAY AND MONDAY WILL FEATURE BELOW NORMAL TEMPERATURES WITH MAX TEMPS GENERALLY IN THE 60S. AS THE AFOREMENTIONED SFC HIGH MOVES OFF THE NEW ENGLAND COAST MONDAY NIGHT AND TUESDAY...ITS CLOCKWISE CIRCULATION WILL OPEN THE DOOR FOR SOMEWHAT MILDER AIR TO RETURN TO THE REGION FROM THE UPPER OHIO VALLEY. TEMPERATURES ON TUESDAY ARE THUS FORECAST TO CLIMB BACK INTO THE LOW TO MID 70S. && .AVIATION /00Z THURSDAY THROUGH MONDAY/... A BAND OF SHOWERS AND SCATTERED THUNDERSTORMS ACROSS WESTERN NY THIS EVENING WILL CONTINUE TO MOVE EAST OVERNIGHT ALONG A MID LEVEL DISTURBANCE AND PRE-FRONTAL TROUGH. THE ACTUAL COLD FRONT WILL CROSS THE AREA OVERNIGHT AND MAY PRODUCE A FEW MORE SHOWERS AND SCATTERED THUNDERSTORMS. VFR WILL PREVAIL MOST OF THE TIME THROUGH 06Z WITH ONLY THE HEAVIER SHOWERS AND STORMS PRODUCING BRIEF/LOCAL MVFR TO IFR CONDITIONS. A FEW STORMS MAY ALSO PRODUCE GUSTY WINDS. LATE TONIGHT THE SHOWERS AND SCATTERED STORMS WILL TAPER OFF FROM WEST TO EAST. IN THE WAKE OF THE SHOWERS SEVERAL HOURS OF MVFR TO IFR CIGS MAY DEVELOP ACROSS THE HIGHER TERRAIN OF THE WESTERN SOUTHERN TIER...FINGER LAKES...AND EAST OF LAKE ONTARIO AS MOISTURE BECOMES TRAPPED BENEATH A SHALLOW FRONTAL INVERSION AND UPSLOPES INTO THE HIGHER TERRAIN. ON THURSDAY ANY EARLY SHOWERS EAST OF LAKE ONTARIO WILL END. THIS WILL LEAVE CLEARING SKIES WITH ANY MVFR/IFR CIGS ACROSS HIGHER TERRAIN SCATTERING OUT BY MID MORNING. VFR WILL THEN PREVAIL THROUGH THE REST OF THE DAY. OUTLOOK... FRIDAY...MAINLY VFR WITH A CHANCE OF SHOWERS AND THUNDERSTORMS ACROSS THE SOUTHERN TIER AND INTERIOR PORTIONS OF THE FINGER LAKES. SATURDAY...MAINLY VFR THOUGH SHOWERS AND THUNDERSTORMS MAY BRING BRIEF FLIGHT RESTRICTIONS. SUNDAY AND MONDAY...MAINLY VFR. && .MARINE... SOUTHWEST WINDS ARE DIMINISHING THIS EVENING ACROSS THE NIAGARA RIVER AND SAINT LAWRENCE RIVER WITH THE LOSS OF DAYTIME MIXING. THERE WILL BE A VEERING TO THE WINDS TO WESTERLY TONIGHT FOLLOWING A COLD FRONTAL PASSAGE. SHOWERS AND A FEW THUNDERSTORMS WILL BE POSSIBLE AS THIS FEATURE MOVES THROUGH WITH THE POTENTIAL FOR LOCALLY HIGHER WIND AND WAVES. THERE IS VERY LITTLE COLD AIR BEHIND THE FRONT AND WE DO NOT EXPECT MUCH INCREASE IN EITHER WINDS OR WAVE HEIGHT LATER TONIGHT AND INTO THURSDAY. EXPECT ANOTHER PERIOD OF NON SCA CONDITIONS ON THE AREA WATER BODIES INTO THE BEGINNING OF THE WEEKEND. LATER SATURDAY SOUTHWEST WINDS WILL INCREASE AHEAD OF A STRONGER COLD FRONT...POSSIBLY NECESSITATING THE HOISTING OF ADDITIONAL SMALL CRAFT FLAGS. && .BUF WATCHES/WARNINGS/ADVISORIES... NY...NONE.
