OCTOBER WAS A TALE OF TWO SEASONS FOR BUFFALO...WITH THE FIRST TWO THIRDS OF THE MONTH ENJOYING LATE SUMMER`S WARMTH...WHILE THE LAST THIRD OF THE MONTH TURNED COOL. OCTOBER WAS A WET MONTH...AND SOME GRAUPEL SHOWERS FELL IN THE LATER COOL DAYS OF THE MONTH. THE AVERAGE TEMPERATURE FOR THE MONTH WAS 54.2F DEGREES WHICH IS ABOUT THREE AND A HALF DEGREES ABOVE NORMAL. OCTOBER`S FIRST THREE WEEKS WERE WARM WITH NINE DAYS TOPPING THE 70F MARK. THE FIRST DAY WITH A BELOW NORMAL MEAN TEMPERATURE OCCURRED ON THE 20TH. FOLLOWING A WARM FRONT...AN 83F DEGREE READING ON THE 6TH WAS THE WARMEST DAY OF THE MONTH. AS THE MONTH TURNED COOLER EIGHT OF THE FINAL TEN DAYS FINISHED BELOW NORMAL. OCTOBER WAS A WET MONTH. MEASURABLE PRECIPITATION FELL ON EIGHTEEN DAYS OF THE MONTH...AND THE 1.22 INCHES OF RAIN ON THE FINAL DAY WAS ENOUGH TO ESTABLISH A NEW DAILY RECORD FOR THE 31ST. THE TOTAL RAINFALL FINISHED WELL ABOVE AVERAGE AT 7.00 INCHES. THIS TOTAL MAKES OCTOBER 2013 THE 6TH WETTEST OF THE 143 OCTOBERS IN BUFFALO`S WEATHER HISTORY BOOK. THERE WERE SEVEN DAYS WITH AT LEAST A HALF INCH OF PRECIPITATION WHICH IS ONE OFF FROM THE MONTHLY RECORD. THERE WERE ONLY TWO DAYS WITH THUNDER...AND TWO DAYS MEASURING A TRACE OF SNOWFALL. OCTOBER`S TEMPERATURES PICKED UP WHERE SEPTEMBER FINISHED...WITH THE STRING OF TEMPERATURES IN THE 70S CONTINUING. A CLOUDY AND RAINY SATURDAY ON THE 5TH ENDED A TEN DAY STREAK OF TEMPERATURES IN THE 70S OR HIGHER...WHICH IS ONE OF THE LONGEST STRETCHES OF SUCH TEMPERATURES FOR THIS LATE IN AUTUMN. A STRONGER COLD FRONT WHICH CROSSED THE REGION ON MONDAY THE 7TH BROUGHT RAIN...AND WITH THE ONSET OF COOLER AIR ALOFT...SOME LAKE EFFECT RAIN SHOWERS. THIS COOL SHOT WAS BRIEF AS WARMER AIR QUICKLY RETURNED. THE WARMER AIR MADE FOR A PLEASANT STRETCH DURING THE SECOND WEEK OF OCTOBER WITH FIVE STRAIGHT DAYS OF SUNSHINE. A SERIES OF COLD FRONTS BROUGHT MORE RAIN STARTING ON THE 13TH WITH SOME LAKE EFFECT RAIN ON THE 17TH AND 18TH. AS THE COOLER AIR DEEPENED...SOME GRAUPEL SHOWERS DEVELOPED...WITH BUFFALO FIRST RECEIVING SOME GRAUPEL AND WET SNOWFLAKES ON THE 23RD. A PATTERN CHANGED BROUGHT COOLER THAN NORMAL CONDITIONS FOR THE FOURTH WEEK OF THE MONTH. CLEAR SKIES AND LIGHT WINDS BROUGHT THE FIRST WIDESPREAD FREEZE TO WESTERN NEW YORK ON THE MORNING OF THE 28TH...ABOUT A WEEK LATER THAN NORMAL. ON THE 31ST...A WARM FRONT LIFTED ACROSS THE REGION AND BROUGHT PERIODS OF RAIN AND TEMPERATURES IN THE UPPER 60S. THE TOTAL MONTHLY SUNSHINE FINISHED TWO PERCENT ABOVE NORMAL...WITH ELEVEN DAYS SEEING MOSTLY SUNNY SKIES. AVERAGE WIND SPEED FOR THE MONTH WAS ABOUT 2 MPH BELOW NORMAL AND THE STRONGEST GUST OF 44 MPH OCCURRED ON THE 7TH WITH THE PASSAGE OF A COLD FRONT. LAKE ERIE CONTINUED TO RUN ABOVE NORMAL THROUGH THE MONTH...WITH THE 64F READING ON THE 17TH SETTING A NEW RECORD HIGH FOR THE DAY. BY MONTHS END LAKE ERIE WAS DOWN TO 54 DEGREES. IN ALL A WET OCTOBER...THOUGH MANY MILD DAYS HELP TO BALANCE THE UNSETTLED WEATHER. && THOMAS $$
