NOVEMBER WILL GO DOWN AS A PERSISTENTLY MILD MONTH, EXCEPT FOR ONE BRIEF COLD SPELL THAT GAVE THE BUFFALO REGION ITS FIRST MEASURABLE SNOWFALL OF THE SEASON. PRECIPITATION FOR THE MONTH REMAINED BELOW NORMAL, THOUGH SEVERAL EVENTS BROUGHT A DECENT AMOUNT OF PRECIPITATION. THE AVERAGE TEMPERATURE FOR NOVEMBER WAS 45.1F DEGREES, PLACING THIS NOVEMBER TIED FOR THE 8TH WARMEST ON RECORD. TEMPERATURE RECORDS FOR BUFFALO DATE BACK TO 1871. THERE WERE 24 DAYS THIS MONTH THAT FINISHED ABOVE NORMAL, AND WHILE THE MONTH AS A WHOLE FINISHED MILD, THERE WERE NO DAILY RECORDS ESTABLISHED. TEMPERATURES REMAINED AT OR ABOVE FREEZING THROUGH THE AUTUMN SEASON, AND IT WAS NOT UNTIL NOVEMBER 21ST THAT THE FIRST SUBFREEZING TEMPERATURE OCCURRED. THIS IS THE 4TH LATEST OCCURRENCE OF A SUBFREEZING TEMPERATURE ON RECORD FOR BUFFALO. IN TOTAL THERE WERE JUST FOUR DAYS THAT REACHED BELOW FREEZING, WHICH IS TIED FOR 5TH FEWEST NUMBER OF DAYS. THE MILD AUTUMN ALSO BROUGHT A LATER TREE FOLIAGE CHANGE THAN NORMAL TO THE REGION. THERE WERE 8 DAYS THIS MONTH THAT TOPPED THE 60F MARK, WHICH IS 4 DAYS MORE THAN NOVEMBER NORMAL. BUFFALO, LIKE MUCH OF THE NORTHEAST U.S. HAD BELOW NORMAL PRECIPITATION THIS MONTH, WITH 3.35 INCHES OF PRECIPITATION MEASURED. THIS IS TWO-THIRDS OF AN INCH BELOW THE NORMAL OF 4.01 INCHES. SEVERAL EVENTS BROUGHT CALENDAR DAY HALF TO ONE INCH PRECIPITATION TOTALS, BUT THERE WERE NO EXTREME OR RECORD BREAKING RAINFALL EVENTS. THE 12 DAYS OF MEASURABLE PRECIPITATION WAS 3 DAYS FEWER THAN NORMAL. SNOWFALL FOR THE MONTH WAS ALSO BELOW NORMAL, WITH JUST 0.9 INCHES MEASURED ON THE 20TH. THERE WERE SEVERAL NOTABLE WEATHER EVENTS THIS MONTH. THE FIRST WAS A LONG DURATION RAIN EVENT, THIS ON THE 2ND AND 3RD OF THE MONTH WHEN WAVES OF RAIN ALONG A WEAK, AND SLOW MOVING COLD FRONTAL BOUNDARY PASSED ACROSS THE REGION. THIS BROUGHT 2-DAY RAINFALL TOTALS OF OVER AN INCH TO MUCH OF WESTERN NEW YORK. THE SECOND EVENT WAS THE FIRST SIGNIFICANT LAKE EFFECT SNOW EVENT FOR THE LOWER GREAT LAKES. A DEEP AREA OF LOW PRESSURE SLOWLY TRAVELED ACROSS SOUTHERN QUEBEC OVER THE WEEKEND OF THE 19TH TO 20TH. THIS SYSTEM TRANSPORTED ATLANTIC MOISTURE OVER THE EASTERN GREAT LAKES THAT FED ABUNDANT MOISTURE INTO BANDS OF LAKE EFFECT SNOW THAT FELL SOUTHEAST OF THE LAKES ON A COLD NORTHWEST FLOW. GREATEST SNOW TOTALS (NEARLY A FOOT) FELL TO THE SOUTHEAST OF LAKE ERIE, AND ALSO EAST OF BUFFALO, WHERE A GEORGIAN BAY CONNECTION BROUGHT A BAND OF SNOW THAT DROPPED A FOOT TO A FOOT AND A HALF OF SNOW ACROSS THE GENESEE VALLEY AND NORTHERN FINGER LAKES REGION. THE THIRD EVENT WAS A STRONG COLD FRONT THAT PASSED ACROSS WESTERN NEW YORK AS THE MONTH OF NOVEMBER CLOSED. THIS FRONT BROUGHT HALF TO ONE INCH OF RAINFALL, AND ALSO PRODUCED A THUNDERSTORM ACROSS THE BUFFALO METRO AREA. OUTSIDE OF THESE THREE EVENTS, THERE WERE A FEW STORM SYSTEMS THAT BROUGHT MINOR RAINFALL AMOUNTS. LAKE ERIE REMAINED QUITE WARM THROUGH THE MONTH, DROPPING FROM 58F DEGREES ON THE 2ND TO 47F DEGREES AT MONTHS END. IN A MONTH THAT FAVORS HIGH WIND EVENTS, THE GREATEST WIND GUST REGISTERED WAS 49 MPH, THIS BEHIND A COLD FRONTAL PASSAGE ON THE 10TH. IN ALL A MILD MONTH FOR WESTERN NEW YORK, INTERRUPTED BRIEFLY BY THE SEASON`S FIRST NOTABLE LAKE EFFECT SNOW EVENT. AUTUMN STATS...SEPTEMBER, OCTOBER, NOVEMBER. DEPARTURE FROM NORMAL IN PARENTHESIS. TEMPERATURE... 55.5F (+4.3) 3RD WARMEST PRECIPITATION... 11.29" (-0.14) 50TH WETTEST SNOWFALL... 0.9" && THOMAS $$
