SIMILAR TO JUNE AND JULY A TROUGH OF LOW PRESSURE CONTINUED TO
DOMINATE THE NORTHEAST US THROUGH MUCH OF AUGUST. THIS TROUGH OF LOW
PRESSURE CONTINUED THE THEME FOR UNSETTLED WEATHER IN NEW HAMPSHIRE.
DURING THE FIRST HALF OF THE MONTH THE NAO REMAINED NEGATIVE WHILE
THE PNA REMAINED POSITIVE WITH THESE TELECONNECTIONS FAVORING A
TROUGH JUST WEST OF NEW ENGLAND. THE NAO DID TREND TOWARDS NEUTRAL
AT TIMES, WHICH ALLOWED THE TROUGH AXIS TO SHIFT NEAR OVERHEAD OF
THE MANCHESTER AREA AND SOMETIMES EAST OF NEW ENGLAND. THIS EASTWARD
SHIFT OF THE TROUGH AXIS ALLOWED FOR COOL AND DRY HIGH PRESSURE
SYSTEMS TO BUILD INTO THE AREA BRINGING PERIODS OF DRY WEATHER WITH
TEMPERATURES TRENDING BELOW NORMAL. TOWARDS THE END OF THE MONTH,
TROPICAL ACTIVITY INCREASED IN THE ATLANTIC BASIN WITH TROPICAL
STORMS TRACKING OFFSHORE OF THE EAST COAST. A SERIES OF FRONTAL
SYSTEMS THAT CROSSED FROM THE WEST HELPED TO PUSH THESE SYSTEM
OFFSHORE WHILE AREA BEACHES DID SEE INCREASED SWELLS.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 70.5 DEGREES, WHICH WAS
1.7 DEGREES BELOW NORMAL. THE COOLEST AUGUST ON RECORD WAS IN 1929
WHEN THE AVERAGE TEMPERATURE WAS 61.1 DEGREES. THE WARMEST WAS IN
2022 WHEN THE AVERAGE TEMPERATURE WAS 76.5 DEGREES.

A TOTAL OF 3.58 INCHES OF PRECIPITATION RECORDED, WHICH WAS 0.23
INCHES ABOVE NORMAL. ON AUGUST 18TH THERE WAS A TIPPING BUCKET ERROR
AND PRECIPITATION FOR THE DAY IS MARKED AS MISSING. NEARBY
OBSERVATIONS IN THE AREA SHOWED AROUND 0.50 INCHES OF RAIN FELL THAT
DAY. THE WETTEST AUGUST ON RECORD WAS IN 2011 WHEN 7.23 INCHES OF
PRECIPITATION FELL. THE DRIEST WAS 0.60 INCHES IN 2007.

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.
