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 CONCORD 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
ACROSS NORTHERN NEW ENGLAND. 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
CONCORD AREA FROM COOLING OFF AT NIGHT THROUGH THE FIRST THREE WEEKS
OF THE MONTH. DURING THIS TIME LOW TEMPERATURES STAYED ABOVE 60
DEGREES AND THERE WERE A FEW NIGHTS WHEN THE LOW TEMPERATURE DID NOT
DROP BELOW 70 DEGREES. IT WASN`T UNTIL THE LAST WEEK OF THE MONTH
WHEN FRONTAL SYSTEMS WERE MORE PROGRESSIVE THAT LOW TEMPERATURES
WERE ABLE TO DROP INTO THE 50S.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 73.3 DEGREES, WHICH WAS
2.2 DEGREES ABOVE NORMAL. THE WARMEST JULY ON RECORD WAS IN 1872
WHEN THE AVERAGE TEMPERATURE WAS 75.2 DEGREES. THE COOLEST WAS 65.4
DEGREES IN 1969.

A TOTAL OF 6.41 INCHES OF PRECIPITATION FELL, WHICH WAS 2.79 INCHES
ABOVE NORMAL. THE HEAVIEST PRECIPITATION FELL ON THE 16TH WHEN 1.53
INCHES OF RAIN FELL. THE WETTEST JULY ON RECORD WAS IN 2021 WHEN
13.04 INCHES OF RAIN FELL. THE DRIEST WAS 0.91 INCHES IN 1910.

THE FOLLOWING DAILY RECORDS WERE SET OR TIED IN JULY 2023...
