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 CONCORD 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 67.6 DEGREES, WHICH WAS
1.9 DEGREES BELOW NORMAL. THE COOLEST AUGUST ON RECORD WAS IN 1903
WHEN THE AVERAGE TEMPERATURE WAS 61.1 DEGREES. THE WARMEST WAS 73.5
DEGREES IN 2022.

A TOTAL OF 4.49 INCHES OF RAIN FELL, WHICH WAS 0.86 INCHES ABOVE
NORMAL. THE HEAVIEST RAIN FELL FROM THUNDERSTORMS ON THE 8TH WHEN
1.25 INCHES WAS MEASURED. THE WETTEST AUGUST ON RECORD WAS IN 2018
WHEN 10.67 INCHES OF PRECIPITATION FELL. THE DRIEST WAS 0.06 INCHES
IN 1906.

NO RECORDS WERE SET OR TIED IN THE MONTH OF AUGUST AT CONCORD.
