ALTHOUGH JUNE MARKS THE BEGINNING OF METEOROLOGICAL SUMMER, IN THIS
PART OF NEW ENGLAND SPRING WEATHER OFTEN LASTS THROUGH MUCH OF JUNE,
AND THAT WAS THE CASE AGAIN THIS YEAR. AN ACTIVE JET STREAM PATTERN
BROUGHT FREQUENT STORM SYSTEMS INTO THE REGION EACH WITH RENEWED
RAINFALL. THE MOST SIGNIFICANT OF THESE MOVED THROUGH ON JUNE 20 AND
21 WHEN MORE THAN AN INCH OF RAIN FELL. SOME WARMER WEATHER MADE AN
APPEARANCE LATE IN THE MONTH WITH THE TEMPERATURE TOPPING 80 DEGREES
ON 4 DAYS.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 62.8 DEGREES WHICH WAS 0.6
DEGREES BELOW NORMAL. HIGH TEMPERATURES WERE WELL BELOW NORMAL WHILE
LOW TEMPERATURES WERE SLIGHTLY ABOVE NORMAL, INDICATIVE OF A CLOUDY
AND WET WEATHER PATTERN. THE COOLEST JUNE ON RECORD WAS IN 1958 WHEN
THE AVERAGE TEMPERATURE WAS ONLY 58.1 DEGREES. THE WARMEST WAS IN
2001 WHEN IT WAS 67.1 DEGREES.

A TOTAL OF 5.85 INCHES OF RAIN FELL WHICH WAS 2.06 INCHES ABOVE
NORMAL. THE HEAVIEST RAIN CAME ON JUNE 20 AND 21 WHEN A STORM SYSTEM
BROUGHT 1.28 INCHES OF RAIN. THE WETTEST JUNE WAS IN 1917 WHEN 10.86
INCHES OF RAIN FELL. THE DRIEST WAS IN 1908 WHEN ONLY 0.53 INCHES
WAS RECORDED.

THE FOLLOWING RECORDS WERE SET OR TIED IN JUNE 2019...
