AFTER WARM WEATHER FOR THE FIRST TWO DAYS OF THE MONTH, A SHIFT TO
ONSHORE WINDS BROUGHT A FEW DAYS OF COOL, DAMP CONDITIONS. BUT SOON
THE WEATHER PATTERN WOULD SHIFT TO WHAT HAD BECOME NORMAL FOR LATE
SPRING: ROUND AFTER ROUND OF COOL, DRY HIGH PRESSURE DROPPING
SOUTHEAST OUT OF THE ARCTIC AND INTO NEW ENGLAND. THIS BROUGHT WARM
DAYS AND COOL NIGHTS FOR MUCH OF THE MONTH WITH ONLY BRIEF PERIODS
OF WARM, HUMID WEATHER AHEAD OF EACH COLD FRONT. THE WARMEST OF
THESE WAS ON JUNE 18 WHEN THE TEMPERATURE REACHED 92 DEGREES BEFORE
A COLD FRONT ARRIVED AGAIN. THE LAST OF THE COOL, DRY HIGH ARCTIC
HIGH PRESSURES MOVED THROUGH ON THE 26TH, WITH CONCORD SEEING THE
TEMPERATURE DROP ALL THE WAY TO 42 DEGREES. THE PATTERN BEGAN TO
SHIFT AT THE END OF JUNE, THOUGH, WHEN A STRONGER LOW PRESSURE
SYSTEM BROUGHT MORE THAN 1.5 INCHES OF RAIN ON JUNE 27 AND 28, THE
MOST SUBSTANTIAL RAINFALL CONCORD HAD SEEN SINCE APRIL. THIS
SIGNALED A SHIFT IN THE WEATHER PATTERN AS WARM, HUMID AIR BEGAN
MOVING INTO NEW ENGLAND FROM THE SOUTHWEST BRINGING 90 DEGREE HEAT
FOR THE LAST TWO DAYS OF THE MONTH.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 64.7 DEGREES WHICH WAS 0.2
DEGREES BELOW NORMAL. THE AVERAGE HIGH WAS A BIT ABOVE NORMAL AND
THE AVERAGE LOW WAS BELOW NORMAL, INDICATIVE OF THE DRY AIR MASSES
THAT FREQUENTED THE AREA DURING THE MONTH. THE COOLEST JUNE ON
RECORD WAS IN 1903 WHEN THE AVERAGE TEMPERATURE WAS 48.8 DEGREES.
THE WARMEST WAS IN 1876 WHEN IT WAS 70.3 DEGREES.

A TOTAL OF 3.06 INCHES OF RAIN FELL WHICH WAS 0.63 INCHES BELOW
NORMAL. THE HEAVIEST RAIN FELL ON THE 27TH AND 28TH WHEN 1.53 INCHES
WAS RECORDED. THE DRIEST JUNE ON RECORD WAS IN 1913 WHEN ONLY 0.10
INCHES WAS RECORDED. THE WETTEST WAS IN 1944 WHEN 10.10 INCHES FELL.

NO DAILY RECORDS WERE SET OR TIED IN JUNE 2018.
