Area forecast discussion, Mar 19, 3:27 PM EDT, 2 hours 11 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BUFFALO NY 327 PM EDT MON MAR 19 2012 .SYNOPSIS... HIGH PRESSURE WILL REMAIN ANCHORED OFF THE ATLANTIC COAST RIGHT THROUGH THURSDAY...ENSURING A CONTINUATION OF UNSEASONABLE SUMMERLIKE WARMTH THROUGH THAT TIME. ASIDE FROM A CHANCE OF SHOWERS AND THUNDERSTORMS LATE THIS AFTERNOON AND EARLY THIS EVENING AS A WEAKENING UPPER LEVEL DISTURBANCE MAKES ITS WAY ACROSS THE AREA...EXPECT CONDITIONS TO REMAIN LARGELY DRY AS WELL. && .NEAR TERM /THROUGH TUESDAY/... IN THE NEAR TERM PERIOD...A WEAK MID LEVEL LOW DRAPED ACROSS WESTERN NEW YORK AND PENNSYLVANIA WILL CONTINUE TO SLOWLY DRIFT SOUTHEAST AND WEAKEN AS IT RUNS SMACK INTO THE CORE OF THE DOMINANT EASTERN CONUS UPPER RIDGE. THROUGH EARLY THIS EVENING...THIS FEATURE WILL CONTINUE TO INTERACT WITH THE UNSTABLE AIRMASS CURRENTLY IN PLACE ACROSS AREAS AWAY FROM ANY LAKE INFLUENCES...WHERE SBCAPES HAVE SOARED TO BETWEEN 500-1500 J/KG WITH DAYTIME HEATING OF OUR UNSEASONABLY WARM AND SOMEWHAT MOIST AIRMASS. THIS WILL RESULT IN SCATTERED SHOWERS AND THUNDERSTORMS PERSISTING THROUGH THAT TIME...THOUGH ANY CHANCES FOR SEVERE STORMS WILL REMAIN EXTREMELY LOW GIVEN THE RATHER WEAK WIND FIELDS IN PLACE ALOFT...WHICH WILL INSTEAD BE MUCH MORE FAVORABLE FOR LOCALIZED HEAVY RAINFALL. CLOSER TO THE LAKES...A MUCH COOLER AND MORE STABLE AIRMASS WILL HELP TO PRECLUDE ANY REAL THUNDER THREAT...THOUGH THIS WILL ALSO BE MORE FAVORABLE FOR SOME AREAS OF FOG...PARTICULARLY ALONG THE CHAUTAUQUA COUNTY SHORE AND THE SOUTH SHORE OF LAKE ONTARIO GIVEN THE WEAK N/NE ONSHORE FLOW CURRENTLY IN PLACE IN THESE AREAS. AFTER SUNSET...THE LOSS OF DIURNAL HEATING/DAYTIME INSTABILITY SHOULD THEN RESULT IN THIS ACTIVITY DIMINISHING RELATIVELY QUICKLY...LEAVING BEHIND WHAT SHOULD BE A QUIET AND DRY BALANCE OF THE NIGHT. WITH NOCTURNAL COOLING...SOME PATCHES/AREAS OF FOG WILL AGAIN BECOME POSSIBLE. THIS WILL ESPECIALLY BE THE CASE WHEREVER IT RAINS THIS AFTERNOON...THOUGH HAVE NOT YET INCLUDED THIS IN THE FORECAST GIVEN THE DIFFICULTY IN PINPOINTING ALL SUCH LOCATIONS AT THIS TIME. AS FOR TUESDAY...THAT SHOULD BE A MAINLY QUIET AND YET ANOTHER UNSEASONABLY WARM DAY AS THE UPPER RIDGE REBUILDS ACROSS THE LOWER LAKES...WITH 850 MB TEMPS OF +10C TO +12C ONCE AGAIN SUPPORTING WIDESPREAD SUMMERLIKE HIGHS IN THE MID AND UPPER 70S AWAY FROM ANY LAKE INFLUENCES. CLOSER TO THE LAKES...THE WEAK LOW LEVEL FLOW SHOULD ALLOW AT LEAST SOME WEAK LAKE BREEZE CIRCULATIONS TO FORM...RESULTING IN COOLER TEMPS IN THE 60S ALONG THE IMMEDIATE LAKESHORES. WHILE THERE WILL STILL BE AN OUTSIDE CHANCE OF A SHOWER ACROSS OUR CENTRAL AND EASTERN ZONES WHICH WILL BE IN CLOSER PROXIMITY TO THE DECAYING MID LEVEL LOW...THE EVEN WEAKER NATURE OF THIS FEATURE WARRANTS NO HIGHER THAN SOME SLIGHT CHANCE POPS FOR NOW. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/... ANY CONVECTION WHICH LINGERS INTO THE EVENING HOURS WILL DIE OUT QUICKLY WITH THE LOSS OF DAY TIME HEATING LEAVING FAIR WEATHER WEATHER FOR THE REMAINDER OF TUESDAY NIGHT. TREND IN THE LATEST MODEL GUIDANCE HAS BEEN TO SLOW THE EASTWARD PROGRESSION OF THE SOUTHERN PLAINS CUT OFF LOW DURING THIS TIME PERIOD. THIS SLOWER MOVEMENT OF THE CUT OFF WILL LEAD TO A HIGHLY ANOMALOUS EASTERN CONUS UPPER RIDGE THROUGH THE PERIOD. BASED ON THE SLOWER SOLUTION HAVE OPTED TO RAISE TEMPERATURES FOR BOTH WEDNESDAY AND THURSDAY SEVERAL DEGREES. RECORDS HIGH TEMPERATURES AT BUFFALO... ROCHESTER...AND WATERTOWN LOOK ATTAINABLE BOTH DAYS...ESPECIALLY WEDNESDAY. MINIMAL SENSIBLE WEATHER WEDNESDAY WITH MOSTLY SUNNY SKIES AS THE ATMOSPHERE WILL BE WELL CAPPED WITH WARMING ALOFT. WEDNESDAY LIKELY TO THE WARMEST OF THIS STRETCH OF RECORD HEAT WITH 850 MB TEMPERATURES FORECAST TO REACH NEAR +14C. QUESTION MARK BEGINS LATER THURSDAY AS A BACKDOOR COLD FRONT STARTS TO APPROACH WITH THE POTENTIAL FOR SOME AFTERNOON CONVECTION...IF ENOUGH INSTABILITY CAN DEVELOP AND THE MID LEVEL CAP CAN BE OVERCOME. && .LONG TERM /FRIDAY THROUGH MONDAY/... LATEST MEDIUM RANGE MODEL AND ENSEMBLE FORECASTS CONTINUING TO SUGGEST THE IDEA OF A BACKDOOR COLD FRONT DROPPING THROUGH THE REGION AT THE BEGINNING OF THE PERIOD. COOLER AIR WILL BUILD DOWN BEHIND THE FRONT...BUT STILL TEMPERATURES AT OR ABOVE NORMAL FOR FRIDAY. THE AIR MASS LOOKS RATHER DRY BEHIND THE FRONT WITH A BROAD CANADIAN HIGH BUILD DOWN THROUGH THE NORTHEAST CONUS. THE REMAINDER OF THE EXTENDED PORTION OF THE FORECAST WILL HINGE ON THE EVOLUTION OF THE UPPER LEVEL LOW WORKING ACROSS THE MIDDLE PART OF THE COUNTRY AND ITS INTERACTION WITH A NORTHERN STREAM WAVE. ECMWF/CANADIAN/GFS ALL SUGGEST MOISTURE BEING DRAWN NORTHWARD WITH DECENT CHANCES FOR SHOWERS FOR BOTH WEEKEND DAYS WITH A GRADUAL IMPROVING TREND DEVELOPING AS THE UPPER LOW PUSHES TO THE EAST COAST BY MONDAY. ASSUMING CLOUDS AND THE POTENTIAL FOR AT LEAST SCATTERED SHOWER ACTIVITY HAVE SUGGESTED COOLER TEMPERATURES DURING THE REST OF THE PERIOD...ALTHOUGH STILL ABOVE NORMAL. && .AVIATION /20Z MONDAY THROUGH SATURDAY/... SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE THIS AFTERNOON AS A WEAK MID LEVEL DISTURBANCE SLOWLY DRIFTS EAST ACROSS THE REGION...AND INTERACTS WITH AN UNSTABLE AIRMASS. OVERALL... CONDITIONS WILL GENERALLY BE VFR...WITH MORE LOCALIZED AREAS OF IFR/MVFR FOUND WITHIN ANY SHRA/TSRA...AS WELL AS ACROSS THE SOUTHERN TIER WHERE SOME LOWER CIGS STILL LINGER. TONIGHT...ANY SHOWERS/STORMS SHOULD DISSIPATE FAIRLY QUICKLY WITH THE LOSS OF DAYTIME HEATING...LEAVING BEHIND MAINLY VFR CONDITIONS. SOME MVFR/IFR IN BR/FG WILL THEN BECOME POSSIBLE LATER ON TONIGHT...ESPECIALLY WHERE ANY RAIN FALLS THIS AFTERNOON. TUESDAY...EXPECT ANY RESTRICTIONS IN BR/FG TO DISSIPATE BY MID-LATE MORNING WITH INCREASING HEATING...WITH GENERAL VFR CONDITIONS THEN EXPECTED TO PREVAIL FOR THE BALANCE OF THE DAY. OUTLOOK... TUESDAY NIGHT THROUGH SATURDAY...MAINLY VFR...WITH A CHANCE OF SHOWERS THURSDAY AND A CHANCE OF SHOWERS/THUNDERSTORMS SATURDAY. && .MARINE... AREAS OF FOG WILL BE COMMONPLACE ACROSS BOTH EASTERN LAKE ERIE AND THE SOUTH HALF OF LAKE ONTARIO THROUGH AT LEAST THIS EVENING. OTHERWISE...HIGH PRESSURE AND MUCH WARMER THAN NORMAL TEMPERATURES WILL REMAIN DOMINANT ACROSS THE LOWER LAKES REGION THROUGH THE END OF THE WORK WEEK...PROMOTING A CONTINUATION OF QUIET MARINE CONDITIONS. && .CLIMATE... RECORD HIGHS...AND HIGH MINIMUMS FOR BUFFALO AND ROCHESTER THIS WEEK. BUFFALO DATE RECORD HIGH (YEAR) HIGH MINIMUM (YEAR) MON 3/19 70 (1921) 58 (1903) TUE 3/20 74 (1903) 51 (1921) WED 3/21 69 (1913) 48 (1948) THU 3/22 71 (1938) 59 (1938) FRI 3/23 78 (1966) 48 (1920) ROCHESTER DATE RECORD HIGH (YEAR) HIGH MINIMUM (YEAR) MON 3/19 77 (1903) 58 (1903) TUE 3/20 79 (1903) 57 (1903) WED 3/21 72 (1921) 43 (1938) THU 3/22 83 (1938) 53 (1938) FRI 3/23 79 (1966) 50 (1938) A COMPARISON OF THIS CURRENT WARM SPELL IN MARCH OF 2012 TO OTHER YEARS SHOWS JUST HOW AMAZING THIS STRETCH OF WARM TEMPERATURES ARE. FOR BUFFALO THE GREATEST AMOUNT OF DAYS REACHING 60F DEGREES OR WARMER IN THE MONTH OF MARCH IS 11 DAYS SET IN 1973. FOR ROCHESTER THE GREATEST AMOUNT OF DAYS REACHING 60F OR WARMER IN THE MONTH OF MARCH IS 12 DAYS SET IN 1946. BASED ON CURRENT FORECAST HIGHS...WE WILL LIKELY TIE THIS MARK ON TUESDAY...AND THEN BREAK THOSE RECORDS ON WEDNESDAY AS BOTH CITIES ARE 2 DAYS SHY OF THEIR RECORD THROUGH SUNDAY MARCH 18TH. A TYPICAL MARCH AVERAGES ABOUT 3 DAYS OF 60F OR GREATER. ANOTHER WAY TO DISPLAY HOW GREAT A STRETCH THIS WARM SPELL IS...IS TO LOOK AT CONSECUTIVE DAYS AT OR ABOVE 60F IN MARCH. FOR BUFFALO THE GREATEST NUMBER OF CONSECUTIVE DAYS 60F OR GREATER IN MARCH WAS 6 DAYS SET IN 1945. FOR ROCHESTER THE GREATEST STRETCH OF 60F OR GREATER TEMPERATURES IN MARCH WAS ALSO 6 DAYS SET IN 1945...1968 AND 1998. PRESENTLY THROUGH SUNDAY MARCH 18TH THE STREAK FOR BUFFALO IS 7 DAYS...AND ROCHESTER 8 DAYS...AND COUNTING. MARCH OF 2012 WILL GO DOWN AS ONE OF...IF NOT THE WARMEST MARCH MONTHS IN RECORDED HISTORY. && .BUF WATCHES/WARNINGS/ADVISORIES... NY...NONE.
