Area forecast discussion, May 13, 8:21 PM EDT, 51 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BUFFALO NY 821 PM EDT FRI MAY 13 2011 .SYNOPSIS... WEAK LOW PRESSURE EXTENDING FROM ILLINOIS THROUGH OHIO WILL CONSOLIDATE OVER NORTHEASTERN OHIO DURING THE WEEKEND. THE LOW WILL BE RESPONSIBLE FOR ANOTHER SPELL OF UNSETTLED WEATHER THROUGH THE BEGINNING OF NEXT WEEK. && .NEAR TERM /THROUGH SATURDAY/... SHOWERS AND SCATTERED THUNDERSTORMS THIS EVENING WILL DIMINISH WITH LOSS OF DAYTIME HEATING. WITHOUT MUCH UPPER LEVEL SUPPORT...WILL BACK OFF TO JUST CHANCE POPS ACROSS WESTERN NEW YORK AFTER MIDNIGHT AND MAINTAIN HIGHER POPS TO THE EAST. WE WILL CONTINUE TO REMAIN UNSTABLE ALOFT AND GIVEN THE RIDGE OF HIGH THETA-E OVER THE EASTERN GREAT LAKES ACTIVITY COULD BLOSSOM AT ANY TIME. TOWARDS THE FINGER LAKES REGION AND EASTERN LAKE ONTARIO REGION WILL CONTINUE WITH LIKELY AND CATEGORICAL THROUGH THE NIGHT AS ACTIVITY ACROSS CENTRAL NEW YORK WILL CARRY ACROSS THIS REGION. EXPECT MOSTLY CLOUDY SKIES AND MILD CONDITIONS THROUGH THE REMAINDER OF THE NIGHT...WITH LOWS GENERALLY IN THE UPPER 50S TO LOWER 60S. IN AREAS THAT RECEIVED HEAVY RAIN...AND GIVEN THE MILD DEW POINTS OVERNIGHT AND LIGHT FLOW WILL INCLUDE PATCHY FOG ACROSS MUCH OF THE SOUTHERN TIER...AND LOWER GENESEE VALLEY REGION. ON SATURDAY AS THE OHIO SURFACE LOW BECOMES A BIT MORE ORGANIZED THERE WILL BE THE POTENTIAL TO DEVELOP STRONGER BOUNDARIES TO INITIATE CONVECTION AND THE POPS REFLECT THE BEST CHANCES FOR RAIN ONCE AGAIN IN THE AFTERNOON. && .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/... THE DOMINANT WEATHER FEATURES DURING THIS PERIOD WILL BE A PERSISTENT CLOSED LOW THAT WILL REMAIN SITUATED OVER THE OHIO VALLEY...AND ITS BROAD SURFACE REFLECTION EXTENDING FROM THE OHIO VALLEY ACROSS THE MID ATLANTIC STATES. TOGETHER...THESE TWO FEATURES WILL MAINTAIN A SOUTHEASTERLY TO EASTERLY FLOW OF MOISTURE-RICH AIR ACROSS OUR AREA...RESULTING IN PLENTY OF CLOUD COVER AND A RATHER HIGH LIKELIHOOD OF RAIN. LOOKING A LITTLE MORE CLOSELY AT THE FORECAST DETAILS...THE STEADIEST RAIN IS MOST LIKELY TO INITIALLY BE FOUND ALONG AND NORTH OF A KBUF-KROC-KSYR AXIS SATURDAY EVENING...OR JUST NORTH OF A STALLED OUT FRONTAL BOUNDARY AND ALONG A RATHER WELL DEFINED MID-LEVEL DEFORMATION ZONE EXTENDING NORTHEASTWARD FROM THE MAIN LOW. SOUTH OF THIS...THE PRECIP SHOULD INITIALLY BE MUCH MORE SHOWERY OWING TO WEAKER AND MORE DIFFUSE FORCING UNDER AN AREA OF BROAD DIFFLUENCE ALOFT. HAVE REFLECTED THIS IN THE FORECAST WITH A NORTH-SOUTH GRADIENT IN PRECIP CHANCES SATURDAY EVENING...RANGING FROM CATEGORICAL NORTH TO LOW LIKELY FURTHER SOUTH. AS TIME PROGRESSES SATURDAY NIGHT AND SUNDAY...THE AFOREMENTIONED SURFACE BOUNDARY AND DEFORMATION ZONE ALOFT SHOULD TEND TO SAG A LITTLE FURTHER TO THE SOUTH. THIS...IN CONJUNCTION WITH ANOTHER SURGE OF MOISTURE WORKING INTO THE AREA FROM THE SOUTH...SHOULD RESULT IN THE STEADIER RAIN SPREADING FURTHER SOUTH ACROSS THE REMAINDER OF THE FORECAST AREA...AND AS SUCH HAVE INDICATED A TREND TOWARD CATEGORICAL POPS EVERYWHERE DURING THIS TIME FRAME. DURING THE SUNDAY NIGHT-MONDAY NIGHT PERIOD...THE MAIN DEFORMATION ZONE WILL REMAIN PARKED ACROSS OUR AREA...HOWEVER LIFT WITHIN THIS ZONE WILL BECOME WEAKER AND MORE DIFFUSE...WHILE SOME MID-UPPER LEVEL DRYING ALSO TAKES PLACE. THIS SHOULD TRANSLATE INTO SOMEWHAT LIGHTER RAIN AND LOWER OVERALL PRECIP CHANCES...THOUGH THERE WILL STILL BE A PRETTY GOOD LIKELIHOOD OF EVERYONE SEEING AT LEAST SOME RAIN...SO HAVE CONTINUED WITH LIKELY POPS. IN CONTRAST TO THE NEAR TERM PERIOD WHICH WILL FEATURE MORE IN THE WAY OF INSTABILITY...OUR REGION WILL BE IN A MORE STABLE ENVIRONMENT DURING THE BULK OF THE SHORT TERM PERIOD...TRANSLATING INTO LITTLE OR NO THREAT FOR THUNDER. ABOUT THE ONLY CHANCE FOR THUNDER WILL COME EARLY SATURDAY EVENING SOUTH OF LAKE ONTARIO...WHERE SOME WEAK ELEVATED INSTABILITY WILL STILL BE PRESENT BEFORE MIDNIGHT. OVERALL...THE HEAVIEST PRECIP AMOUNTS DURING THIS PERIOD APPEAR MOST LIKELY DURING THE SATURDAY NIGHT AND SUNDAY TIME FRAME...WHEN LIFT ALONG THE DEFORMATION ZONE WILL BE THE STRONGEST AND MOST PERSISTENT. POTENTIAL RAINFALL AMOUNTS THROUGH SUNDAY LOOK TO RANGE FROM AROUND AN INCH TO AN INCH AND A THIRD ALONG AND NORTH OF A KBUF-KROC-KSYR LINE...TO A HALF TO TWO THIRDS OF AN INCH FURTHER SOUTH. THIS WILL THEN LIKELY BE FOLLOWED BY ANOTHER GENERAL QUARTER TO HALF AN INCH OF RAIN AS THE DEFORMATION ZONE SLOWLY WEAKENS IN PLACE SUNDAY NIGHT AND MONDAY. WITH ALL THE CLOUD COVER AND PRECIP...THE DIURNAL SPREAD IN TEMPERATURES WILL BE SIGNIFICANTLY SMALLER THAN USUAL...WITH NIGHTTIME LOWS RUNNING FROM NEAR NORMAL TO ABOVE NORMAL...AND DAYTIME HIGHS REMAINING BELOW NORMAL. IN FACT...READINGS WILL LIKELY NOT MAKE IT OUT OF THE MID 50S IN MOST PLACES ON MONDAY...WHICH WILL BE A SOLID 10 DEGREES BELOW NORMAL FOR MID MAY. && .LONG TERM /TUESDAY THROUGH FRIDAY/... IN A NUTSHELL...THIS PERIOD STILL LOOKS AS IF IT WILL REMAIN UNSETTLED...WITH BELOW NORMAL TEMPERATURES AND ABOVE NORMAL RAINFALL CONTINUING. THE MEDIUM RANGE OPERATIONAL AND ENSEMBLE GUIDANCE REMAINS IN GOOD AGREEMENT THAT A PERSISTENT CLOSED UPPER LOW WILL LINGER OVER THE OHIO VALLEY THROUGH AT LEAST MIDWEEK...BEFORE SLOWLY WEAKENING AND LIFTING OUT ACROSS THE GREAT LAKES REGION TOWARD THE END OF THE PERIOD. THIS PATTERN WILL ALLOW FOR A FAIR AMOUNT OF CLOUD COVER AND SHOWER ACTIVITY TO PERSIST ACROSS OUR AREA THROUGH WEDNESDAY... BEFORE DRIER AIR GETS ENTRAINED INTO THE CIRCULATION OF THE WEAKENING LOW AND LEADS TO SOMEWHAT DIMINISHED SHOWER CHANCES FOR BOTH THURSDAY AND FRIDAY. && .AVIATION /00Z SATURDAY THROUGH WEDNESDAY/... AT 00Z SHOWERS AND THUNDERSTORMS CONTINUE TO WEAKEN WITH THE LOSS OF DAYTIME HEATING. THUNDERSTORMS WILL BE SLOW MOVING AND LIKELY REMAIN IN THE VICINITY OF KROC FOR ANOTHER HOUR OR SO BEFORE DRIFTING SLOWLY NORTH AND EASTWARD. ELSEWHERE VFR FLIGHT CONDITIONS...THOUGH A LOWERING INTO IFR IN LOW CEILINGS AND FOG IS LIKELY ACROSS THE SOUTHERN TIER WHERE HEAVY RAIN HAS FALLEN...AND HIGH DEWPOINTS REMAIN. GIVEN THE AIRMASS WILL REMAIN UNSTABLE ALOFT THROUGH THE NIGHT HOURS...A SHOWER IS POSSIBLE ACROSS WESTERN NEW YORK AND PORTIONS OF CENTRAL NEW YORK TOWARDS DAWN. ON SATURDAY GENERALLY VFR CONDITIONS WILL PREVAIL BUT WE SHOULD SEE A RETURN OF CONVECTION DURING THE AFTERNOON ACROSS MOST OF THE CWA THAT WILL OCCASIONALLY TAKE CONDITIONS DOWN TO MVFR. ACTIVITY WILL LINGER TOWARDS THE EVENING HOURS...DIMINISHING WITH THE LOSS OF DAYTIME HEATING. OUTLOOK... SATURDAY NIGHT THROUGH WEDNESDAY...MVFR WITH RAIN LIKELY THROUGH TUESDAY...BEFORE DIMINISHING TO SCATTERED SHOWERS ON WEDNESDAY. && .MARINE... AS NOTED ABOVE THE WEAK AREA OF LOW PRESSURE EXTENDING FROM ILLINOIS THROUGH OHIO WILL CONSOLIDATE OVER NORTHEASTERN OHIO DURING THE WEEKEND. THROUGH SATURDAY WINDS WILL GENERALLY BE LIGHT RESULTING IN CONDITIONS REMAINING BELOW ADVISORY CRITERIA. SATURDAY NIGHT AND SUNDAY THE SURFACE LOW CONSOLIDATES OVER NORTHEAST OHIO AND HIGH PRESSURE FROM CENTRAL CANADA SLIDES SOUTHEAST TO THE UPPER GREAT LAKES. THAT COMBINATION WILL CREATE A TIGHTER PRESSURE GRADIENT ACROSS THE LOWER GREAT LAKES RESULTING IN BRISK NORTHEASTERLY FLOW...WITH WINDS AND WAVES LIKELY TO REACH SMALL CRAFT ADVISORY CRITERIA THROUGH EARLY NEXT WEEK. && .BUF WATCHES/WARNINGS/ADVISORIES...
