AFTER A RELATIVELY COOL AUGUST, THE COOL FALL-LIKE WEATHER CONTINUED  
INTO THE FIRST FEW DAYS OF SEPTEMBER. AFTER A FEW DAYS OF RAIN, A  
NEW WEATHER PATTERN BEGAN TO EMERGE. A RIDGE OF HIGH PRESSURE OVER  
THE WESTERN ATLANTIC AND THE EAST COAST BROUGHT RELATIVELY WARM AIR  
NORTHWARD INTO NEW ENGLAND. ALTHOUGH A FEW COLD FRONTS MANAGED TO  
SNEAK INTO THE AREA BRINGING BRIEFLY COOLER WEATHER, THE OVERALL  
TREND OF WARMER THAN NORMAL TEMPERATURES CONTINUED FOR SEVERAL  
WEEKS. THE WARMEST PERIOD WAS IN LATE SEPTEMBER WHEN THE TEMPERATURE  
SURPASSED 85 DEGREES FOR 5 STRAIGHT DAYS FROM SEPTEMBER 23 THROUGH  
27. THE PERSISTENT WARMTH CONTINUED DEEP INTO OCTOBER. AFTER A  
MOSTLY DRY FIRST HALF OF FALL, A SERIES OF LOW PRESSURE SYSTEMS  
MOVED THROUGH NEW ENGLAND LATE IN OCTOBER. MORE THAN 3 INCHES OF  
RAIN FELL FROM OCTOBER 24 THROUGH 26. ANOTHER LOW PRESSURE SYSTEM  
BROUGHT ANOTHER TWO INCHES OF RAIN AND STRONG WINDS GUSTING TO 58  
MPH ON THE NIGHT OF OCTOBER 29 INTO THE MORNING OF THE 30TH. THE  
STRONG WINDS BROUGHT WIND DAMAGE TO THE REGION. THIS PERIOD OF  
STORMY WEATHER SIGNALED A COMING CHANGE IN THE WEATHER PATTERN AS  
THE PERSISTENT WARMTH FINALLY BEGAN TO BREAK DOWN. AFTER ANOTHER  
BRIEF PERIOD OF WARMTH, A COLD FRONT ON NOVEMBER 6 BROUGHT COLD AIR  
INTO THE REGION. EVEN COLDER AIR POURED IN STRAIGHT OUT OF THE  
ARCTIC A FEW DAYS LATER. THE FIRST MEASURABLE SNOW OF THE SEASON  
OCCURRED ON NOVEMBER 13 WHEN 0.1 INCHES FELL. COLD WEATHER CONTINUED  
THROUGH MUCH OF NOVEMBER WITH ONLY BRIEF EXCEPTIONS AS A SERIES OF  
COLD FRONTS KEPT BRINGING MORE COLD AIR IN DURING THE MONTH.  
 
THE AVERAGE TEMPERATURE FOR THE FALL WAS 55.7 DEGREES WHICH WAS 4.1  
DEGREES ABOVE NORMAL. THE TEMPERATURE RANGED FROM 90 DEGREES ON  
SEPTEMBER 24 TO 19 DEGREES ON NOVEMBER 28. A TOTAL OF 12.19 INCHES  
OF RAIN FELL WHICH WAS 0.15 INCHES ABOVE NORMAL. THE HEAVIEST RAIN  
FELL ON OCTOBER 24 THROUGH 26 WHEN 3.42 INCHES WAS MEASURED. ONLY  
0.1 INCHES OF SNOW FELL ON NOVEMBER 13.  
 
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.
