SEPTEMBER FEATURED A FAMILIAR WEATHER PATTERN WITH A FREQUENT RIDGE  
OF HIGH PRESSURE OVER THE EAST COAST OR THE WESTERN ATLANTIC  
ALLOWING WARM, HUMID AIR TO MOVE NORTH AND INTO NEW ENGLAND. THE  
WARMEST STRETCH WAS AT THE BEGINNING OF THE MONTH WHEN MANCHESTER  
SAW 4 STRAIGHT DAYS OF 90 DEGREE HEAT ALONG WITH HIGH HUMIDITY. A  
COLD FRONT CAME THROUGH AND BROUGHT A FEW DAYS OF COOLER WEATHER,  
BUT THEN AFTER A FEW DAYS OF RAIN THE WARM AND HUMID WEATHER  
RETURNED FOR THE MIDDLE OF THE MONTH. HURRICANE FLORENCE MADE  
LANDFALL IN NORTH CAROLINA BUT EVENTUALLY ITS REMNANTS MOVED THROUGH  
NEW ENGLAND. MANCHESTER RECEIVED MORE THAN 3 INCHES OF RAIN AS THIS  
MOVED THROUGH ON THE 18TH. ANOTHER COLD FRONT BROUGHT SOME COOLER  
WEATHER FOR A FEW DAYS BEFORE THE WARMTH BEGAN TO BUILD AGAIN.  
 
THE AVERAGE TEMPERATURE FOR THE MONTH WAS 66.6 DEGREES WHICH WAS 4.0  
DEGREES ABOVE NORMAL. THE TEMPERATURE RANGED FROM 94 DEGREES ON THE  
3RD TO 44 DEGREES ON THE 30TH. A TOTAL OF 7.30 INCHES OF RAIN FELL  
WHICH WAS 3.49 INCHES ABOVE NORMAL AND THE WETTEST SEPTEMBER SINCE  
2008. THE HEAVIEST RAIN FELL ON THE 18TH WHEN 3.86 INCHES WAS  
MEASURED.  
 
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.
