FOR A SECOND CONSECUTIVE YEAR, THE MONTH OF NOVEMBER AVERAGED WELL BELOW NORMAL TEMPERATURES...AIDED BY THE COLDEST FIRST HALF OF NOVEMBER ON RECORD. SNOWFALL WAS ALSO WELL ABOVE MONTHLY NORMS, WITH A MID-MONTH WIDESPREAD SNOWSTORM ACCOUNTING FOR MUCH OF THIS MONTHS SNOWS. THE TEMPERATURE THIS MONTH AVERAGED 35.8F WHICH IS ALMOST 5 DEGREES BELOW NORMAL. THIS AVERAGE TEMPERATURE RANKS 12TH COLDEST FOR NOVEMBER ON RECORD. THE WARMEST TEMPERATURE MEASURED WAS 62F ON THE 27TH...AND THIS WAS THE ONLY OCCURRENCE OF 60S THIS MONTH...MUCH LESS THAN THE AIRPORT NORMAL OF 5 DAYS. THERE WERE 5 DAYS THAT REMAINED AT OR BELOW FREEZING...TIED WITH NOVEMBER OF 2014 AND IS ALSO THE MOST AMOUNT OF DAYS AT OR BELOW FREEZING IN NOVEMBER SINCE 1951 WHEN THERE WERE 7 SUCH DAYS. THERE WERE 3 TEMPERATURE RECORDS SET, ALL OCCURRING IN A MID-MONTH COLD SPELL. THE HIGH TEMPERATURE ON THE 12TH WAS ONLY 25F, BREAKING THE RECORD COLDEST MAXIMUM FOR THE DATE PREVIOUSLY SET BACK IN 1983 (31F). THE LOW TEMPERATURE ON THE 12TH (16F) ALSO BROKE A RECORD LOW TEMPERATURE THAT WAS SET BACK IN 1921 (22F). THE NEXT DAY, THE TEMPERATURE DIPPED EVEN COLDER, DOWN TO 14F WHICH BROKE THE RECORD LOW FOR THE 13TH, THAT WAS PREVIOUSLY SET BACK IN 1986 (16F). PRECIPITATION WAS MUCH BELOW NORMAL FOR THE MONTH, TOTALING 1.97 INCHES. THIS TOTAL IS MORE THAN 2 INCHES BELOW NORMAL. OF THIS MONTHLY TOTAL, OVER HALF FELL AS SNOW. THE BIG PRECIPITATION EVENT FOR THE MONTH OCCURRED ON THE 11TH AND 12TH AS A WIDESPREAD SNOW EVENT UNFOLDED. A DAILY RECORD 8.7 INCHES OF SNOW FELL ON VETERANS DAY. OTHERWISE THE GREATEST PRECIPITATION EVENT WAS JUST 0.24 INCHES ON THE 5TH OF THE MONTH. SINCE RECORDS MOVED TO THE AIRPORT IN 1943, EVERY NOVEMBER HAS HAD AT LEAST 2 CALENDAR DAYS WITH A QUARTER OF AN INCH OF PRECIPITATION...EXCEPT FOR THIS NOVEMBER. IN TOTAL THERE WAS 12.6 INCHES OF SNOW MEASURED FOR THE MONTH. NOVEMBER STARTED VERY WINDY, AS THE HALLOWEEN WIND EVENT CARRIED OVER INTO THE FIRST FEW HOURS OF NOVEMBER WITH NUMEROUS POWER OUTAGES ACROSS THE REGION. THE SOUTHWEST WINDS ALSO PUSHED A SEICHE ON LAKE ERIE TO JUST OVER 10.5 FEET IN THE FIRST HOUR OF THE MONTH..WHICH PRODUCED DAMAGE ALONG THE COASTLINE FROM DUNKIRK TO BUFFALO. COLD AIR BEHIND A COLD FRONT, BROUGHT THE AVERAGE TEMPERATURE FOR THE 1ST TO BELOW NORMAL, AND THIS BELOW NORMAL TEMPERATURE TREND CONTINUED FOR THE NEXT 3 WEEKS. A PLUNGE OF POLAR AIR MID-MONTH BROUGHT EXTREME NOVEMBER COLD TEMPERATURES, WITH BOTH THE 12TH AND 13TH SETTING RECORD LOW TEMPERATURES WHILE ALSO AVERAGING 21 DEGREES BELOW NORMAL. THIS FRESH ARCTIC AIR ALSO SET THE STAGE FOR AN EARLY SEASON WIDESPREAD SNOW EVENT ACROSS WESTERN NEW YORK. ON NEARLY A FOOT-MAGNITUDE SCALE, THIS SNOW EVENT WAS ONE OF THE EARLIEST WIDESPREAD SNOW EVENTS FOR BUFFALO ON RECORD. AS BELOW NORMAL TEMPERATURES CONTINUED, THE SNOWPACK REMAINED ACROSS BUFFALO TILL THE 19TH OF THE MONTH. A MINOR WIND EVENT OCCURRED ON THE 22ND AS A SURFACE LOW DEEPENED ACROSS EASTERN CANADA. A MORE WIDESPREAD WIND EVENT OCCURRED ON THE 27TH AS A DEEP SURFACE LOW TRACKED JUST TO THE WEST AND NORTH OF WESTERN NEW YORK, AND SENT WINDS GUSTING TO 59 MPH AT THE AIRPORT. IN ADDITION TO TREE DAMAGE AND LOCALIZED POWER OUTAGES, ANOTHER SEICHE OCCURRED FOR THE MONTH, WITH WATER RISES ON THIS EVENT UP TO NEAR 9.5 FEET ABOVE LOW WATER DATUM. THE LAST 10 DAYS OF THE MONTH ALSO WERE NOT NEARLY AS COLD AS THE START OF THE MONTH...AND INCLUDED A DAY IN THE 60S ON THE 27TH. WHILE SNOW HAMPERED MID-MONTH OUTDOOR WORK, A RELATIVELY DRY AND MILD END TO THE MONTH ALLOWED FOR LATE AUTUMN OUTDOOR WORK TO BE COMPLETED. THE TEMPERATURE ON LAKE ERIE DROPPED FROM 56F AT MONTHS START TO 44F DEGREES IN THE CLOSING DAYS OF THE MONTH. AFTER LAKE TEMPERATURES RAN ABOVE NORMAL EARLY IN THE AUTUMN SEASON, A COLDER THAN NORMAL NOVEMBER BROUGHT THE LAKE TEMPERATURE DOWN TO NEARLY NORMAL BY THE END OF THE MONTH. EVEN WITH SEVERAL STRONG WIND EVENTS THIS MONTH, THE AVERAGE WIND SPEED WAS ABOUT A HALF MILE-PER-HOUR BELOW NORMAL FOR THE MONTH. THE STRONGEST WIND GUST WAS FROM THE SOUTHWEST ON THE 27TH, REGISTERING A SPEED OF 59 MPH. IN ALL, A COLD AND SNOWY START TO THE MONTH...MODIFIED BY A MILD END. && THOMAS $$
