A BROAD RIDGE OF HIGH PRESSURE ALONG THE EAST COAST DOMINATED THE
WEATHER THROUGH THE FIRST WEEK OF OCTOBER. THIS BROUGHT A PERIOD OF
DRY AND VERY WARM CONDITIONS TO THE MANCHESTER AREA. THE RIDGE BROKE
DOWN BY THE END OF THE FIRST WEEK WITH A FRONTAL SYSTEM CROSSING THE
AREA BRINGING RAIN AND MUCH COOLER TEMPERATURES. AN UPPER LOW
LINGERED NEAR NEW ENGLAND THROUGH MUCH OF THE SECOND WEEK OF THE
MONTH KEEPING TEMPERATURES NEAR NORMAL WITH SHOWERY WEATHER.
ADDITIONAL UPPER LOWS AND TROUGHS CROSSED THE NORTHEAST THROUGH THE
THIRD WEEK OF THE MONTH LIMITING ANY SIGNIFICANT WARM UPS, ALTHOUGH
CONDITIONS WERE MOSTLY DRY WITH ONLY A COUPLE LIGHT RAIN EVENTS. A
MORE SIGNIFICANT SYSTEM IMPACTED THE MANCHESTER AREA THE WEEKEND OF
THE 21ST INTO THE 22ND AS LOW PRESSURE TRACKED ACROSS SOUTHERN NEW
ENGLAND INTO THE GULF OF MAINE BRINGING A SOAKING RAIN. A WARM UP
ENSUED THE FINAL WEEK OF THE MONTH FOLLOWED BY ANOTHER LOW PRESSURE
SYSTEM BRINGING RAIN AND A SHOT OF MUCH COLDER AIR TO CLOSE OUT THE
MONTH. THIS SHOT OF COLDER AIR DROPPED THE MANCHESTER AREA BELOW
FREEZING FOR THE FIRST TIME THIS FALL WHEN THE LOW TEMPERATURE
REACHED 31 DEGREES ON THE 31ST.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 57.4 DEGREES, WHICH WAS
5.2 DEGREES ABOVE NORMAL. THE WARMEST OCTOBER ON RECORD WAS IN 2017
WHEN THE AVERAGE TEMPERATURE WAS 59.6 DEGREES. THE COOLEST WAS 43.1
DEGREES IN 1888

A TOTAL OF 2.33 INCHES OF PRECIPITATION FELL, WHICH WAS 1.55 INCHES
BELOW NORMAL. THE DRIEST OCTOBER WAS IN 1949 WHEN ONLY 0.38 INCHES
OF PRECIPITATION FELL. THE WETTEST WAS IN 2005 WHEN 12.47 INCHES OF
PRECIPITATION FELL.

HISTORICAL RECORDS AT MANCHESTER BEGAN IN 1885, BUT WITHIN THIS
RECORD THERE REMAIN NUMEROUS YEARS OF UNAVAILABLE DATA. DUE TO THIS,
HISTORICAL RECORDS SHOULD BE CONSIDERED INCOMPLETE AS SOME
SIGNIFICANT EXTREMES MAY BE MISSING FROM THE DATA. MORE CONSISTENT
MODERN RECORDS BEGAN IN 1998 AND CONTINUE TO THE PRESENT.
