THE SUMMER SEASON STARTED OFF COOL AND DAMP IN THE MANCHESTER AREA
AS AN UPPER LOW REMAINED NEARLY STATIONARY OVER THE CANADIAN
MARITIMES THROUGH THE FIRST SEVERAL DAYS OF JUNE. ONCE THIS UPPER
LOW LOOSENED ITS GRIP ON THE REGION, TEMPERATURES REBOUNDED CLOSER
TO NORMAL WHILE ADDITIONAL TROUGHS OF LOW PRESSURE CROSSED THE
REGION BRINGING A SOAKING RAIN TO BEGIN THE SECOND WEEK OF JUNE.
ANOTHER UPPER LOW ROLLED ACROSS SOUTHERN CANADA AND SETTLED OVER NEW
ENGLAND AT THE END OF THE THIRD WEEK OF JUNE BRINGING SEVERAL DAYS
OF BELOW NORMAL TEMPERATURES. DURING THIS PERIOD, THE UPPER LOW
BROUGHT SUB-FREEZING TEMPERATURES AT THE HIGHEST PEAKS IN THE WHITE
MOUNTAINS WITH MT WASHINGTON RECORDING 1.7 INCHES OF SNOW FROM THE
18TH INTO THE 19TH. TEMPERATURES THEN REBOUNDED CLOSER TO NORMAL
DURING THE FINAL WEEK OF JUNE. THE PERSISTENT TROUGHING AND UPPER
LOWS OVER THE NORTHEAST LED TO TEMPERATURES RUNNING CLOSE TO NORMAL
FOR THE MONTH OF JUNE, BUT THIS WOULD CHANGE THROUGH THE END OF
SUMMER. THE PERSISTENT TROUGHING OVER THE NORTHEAST US CONTINUED
INTO JULY, ALTHOUGH THE CORE OF THE TROUGH SHIFTED FARTHER NORTH
INTO EASTERN CANADA WITH THE TROUGH AXIS BECOMING ALIGNED ALONG A
SIMILAR LONGITUDE TO MANCHESTER. THIS TROUGH POSITION ACTED TO
SUPPRESS MOISTURE SOUTH OF NEW ENGLAND AND FAVORED HIGH PRESSURE
SYSTEMS TO BUILD INTO NEW ENGLAND FROM THE NORTHWEST BRINGING DRY
AND COOL CANADIAN AIRMASSES THROUGH THE MIDDLE OF JULY. DURING THE
THIRD WEEK OF JULY THE TROUGH STARTED TO SHIFT TO THE WEST AND
ALLOWED FOR WARMER AND MORE HUMID AIRMASSES TO ENTER THE REGION.
FROM JULY 19TH TO THE 24TH MANCHESTER EXPERIENCED 6 STRAIGHT DAYS
WITH HIGH TEMPERATURES AT OR ABOVE 90 DEGREES. THE HEAT AND HUMIDITY
CONTINUED INTO AUGUST WITH THE HOTTEST STRETCH OF THE SUMMER
OCCURRING FROM AUGUST 2ND TO THE 9TH WHEN THE HIGH TEMPERATURES
CLIMBED TO AT LEAST 90 DEGREES WITH THE HOTTEST DAY REACHING 99
DEGREES ON AUGUST 4TH AND AGAIN ON THE 8TH. A SLOW MOVING COLD FRONT
CROSSED THE AREA LATE AUGUST 9TH BRINGING RELIEF FROM THE HEAT WITH
TEMPERATURES RUNNING BELOW NORMAL THROUGH THE MIDDLE OF AUGUST. THE
SECOND HALF OF AUGUST FEATURED A BUILDING RIDGE IN THE WESTERN
ATLANTIC THAT ALLOWED FOR THE HEAT AND HUMIDITY TO RETURN WITH
TEMPERATURES RUNNING ABOVE NORMAL THROUGH THE END OF SUMMER.
RAINFALL AVERAGED BELOW NORMAL DURING ALL OF THE SUMMER MONTHS WITH
THE LAST MONTH THAT MANCHESTER RECEIVED ABOVE NORMAL RAINFALL
OCCURRING BACK IN APRIL. THIS LED TO EXPANDING AND INTENSIFYING
DROUGHT CONDITIONS ACROSS NEW ENGLAND DURING THE SUMMER WITH THE
MANCHESTER AREA STILL EXPERIENCING SEVERE DROUGHT CONDITIONS TO
CLOSE OUT THE SUMMER SEASON.
THE AVERAGE TEMPERATURE FOR SUMMER WAS 73.9 DEGREES, WHICH WAS 2.5
DEGREES ABOVE NORMAL AND THE SECOND WARMEST SUMMER ON RECORD. THE
WARMEST SUMMER WAS IN 2020 WHEN THE AVERAGE TEMPERATURE WAS 74.4
DEGREES. THE COOLEST WAS 64.9 DEGREES IN 1946.
A TOTAL OF 6.39 INCHES OF PRECIPITATION FELL, WHICH WAS 4.30 INCHES
BELOW NORMAL. THE DRIEST SUMMER WAS IN 2016 WHEN ONLY 5.21 INCHES OF
PRECIPITATION FELL. THE WETTEST WAS 20.32 INCHES IN 1938. THE
HEAVIEST PRECIPITATION FELL ON JUNE 9TH WHEN 1.06 INCHES WERE
RECORDED.
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.
