THE NAO REMAINED DEEP INTO NEGATIVE TERRITORY THROUGH THE FIRST TWO
WEEKS OF JULY ALLOWING FOR THE THEME OF WET, CLOUDY, AND OFTEN FOGGY
WEATHER TO CONTINUE IN THE GRAY AREA. A BLOCKING RIDGE OF HIGH
PRESSURE NEAR LABRADOR, CANADA INHIBITED THE ABILITY FOR INCOMING
FRONTAL SYSTEMS TO SWEEP ACROSS NORTHERN NEW ENGLAND. INSTEAD, THESE
FRONTS OFTEN STALLED OVER THE AREA PROVIDING A FOCUS FOR HEAVY
RAINFALL EVENTS AND ALLOWED FOR HUMID AIRMASSES TO BECOME ENTRENCHED
ALONG THE COASTAL PLAIN OF MAINE. DURING THE SECOND HALF OF JULY THE
NAO TRENDED TOWARDS NEUTRAL AS THE BLOCKING RIDGE WEAKENED AND
SHIFTED EAST. HOWEVER, BROAD TROUGHING CONTINUED OVER THE NORTHEAST
THROUGH MUCH OF THE SECOND HALF OF THE MONTH, ONLY DURING THIS TIME
FRONTS WERE ABLE TO MAKE A CLEAN SWEEP ACROSS THE AREA LEAVING A FEW
DAYS OF DRY WEATHER IN BETWEEN SYSTEMS. THE HUMID AIRMASSES LIMITED
THE GRAY AREA TO COOL OFF AT NIGHT WITH LOW TEMPERATURES STAYING
ABOVE 60 DEGREES THROUGHOUT THE MONTH. AT THE END OF THE MONTH A
SERIES OF COLD FRONTS CROSSED THE AREA BRINGING COOLER AND DRIER AIR
ALLOWING FOR THE LOW TEMPERATURE TO DROP INTO THE 50S THE LAST THREE
NIGHTS OF THE MONTH.
THE AVERAGE TEMPERATURE FOR THE MONTH WAS 71.4 DEGREES, WHICH WAS
1.9 DEGREES ABOVE NORMAL. THE WARMEST JULY ON RECORD WAS IN 2011
WHEN THE AVERAGE TEMPERATURE WAS 73.2 DEGREES. THE COOLEST WAS 65.7
DEGREES IN 2009.
A TOTAL OF 7.09 INCHES OF PRECIPITATION FELL, WHICH WAS 3.36 INCHES
ABOVE NORMAL. THE HEAVIEST PRECIPITATION FELL FROM THUNDERSTORMS ON
THE 29TH WHEN 2.43 INCHES FELL. THE WETTEST JULY ON RECORD WAS IN
2021 WHEN 10.47 INCHES OF RAIN FELL. THE DRIEST WAS 1.08 INCHES IN
2003.
