WHILE THE LAST FEW MONTHS SAW PERSISTENT WARMTH UNDERNEATH A RIDGE
OF HIGH PRESSURE, THE WEATHER PATTERN SHIFTED IN OCTOBER. THE WARM
WEATHER PERSISTED FOR THE FIRST PART OF THE MONTH, CLIMAXING WITH
TWO DAYS IN THE 80S ON OCTOBER 9 AND 10. BUT A COLD FRONT BLEW
THROUGH LATE ON THE 10TH WHICH BROUGHT COOLER TEMPERATURES FOR THE
REST OF THE MONTH. A TROUGH OF LOW PRESSURE OVER THE CENTRAL AND
EASTERN PART OF THE COUNTRY BROUGHT SEVERAL ROUNDS OF COLDER WEATHER
ALONG WITH FREQUENT CLOUDS AND PRECIPITATION. THE FIRST FREEZE OF
THE SEASON CAME ON OCTOBER 18 ALONG WITH THE FIRST FLAKES OF SNOW.
THE CLOUDY WEATHER LED TO COOLER THAN NORMAL HIGH TEMPERATURES WITH
WARMER THAN NORMAL LOW TEMPERATURES.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 50.4 DEGREES WHICH WAS THE
COLDEST OCTOBER SINCE 2009. THE TEMPERATURE RANGED FROM 84 DEGREES
ON THE 10TH TO 28 DEGREES ON THE 31ST. A TOTAL OF 2.98 INCHES OF
PRECIPITATION FELL WHICH WAS 1.18 INCHES BELOW NORMAL. ALTHOUGH
TOTAL PRECIPITATION WAS BELOW NORMAL, THERE WERE 14 DAYS WITH
MEASURABLE RAINFALL, ABOUT 40 PERCENT MORE THAN NORMAL. A TRACE OF
SNOW WAS REPORTED ON THE 18TH, THE FIRST SNOWFALL REPORTED IN
OCTOBER SINCE 2011.

HISTORICAL RECORDS AT MANCHESTER ARE NOT PROVIDED DUE TO NUMEROUS
MISSING YEARS WITHIN THE HISTORICAL RECORD. ALTHOUGH THE EARLIEST
DATA AVAILABLE IS IN 1885, THERE ARE SIGNIFICANT GAPS IN THE DATA. A
LOCAL STUDY HAS YET TO BE COMPLETED TO DETERMINE IF MEANINGFUL
INFORMATION ON EXTREME TEMPERATURE, PRECIPITATION, OR SNOWFALL CAN
BE REPORTED.
