JUNE BEGAN WITH MUCH THE SAME WEATHER PATTERN THAT DOMINATED SPRING.
AN ACTIVE JET STREAM BROUGHT FREQUENT STORM SYSTEMS NEAR THE AREA
BRINGING MORE RAIN EVERY FEW DAYS. THE FREQUENT CLOUDS AND RAIN KEPT
TEMPERATURES COOL UNTIL THE PATTERN FINALLY BEGAN TO SHIFT IN LATE
JUNE WITH WARMER SUMMER-LIKE WEATHER ARRIVING. THIS WARMER WEATHER
GRADUALLY BUILT THROUGH THE BEGINNING OF JULY, PEAKING AT 91 DEGREES
ON JULY 6. A COLD FRONT BROUGHT TEMPERATURES BACK TO NEAR NORMAL
LEVELS FOR THE NEXT WEEK OR SO BEFORE THE HEAT BEGAN TO BUILD AGAIN.
THE TEMPERATURE TOPPED 90 DEGREES AGAIN ON JULY 20 AND 21 BEFORE THE
NEXT COLD FRONT KNOCKED THE TEMPERATURE BACK AGAIN FOR THE NEXT
WEEK. ONE FINAL STRETCH OF WARM WEATHER ARRIVED IN LATE JULY BUT
GRADUALLY FADED IN THE FIRST PART OF AUGUST. SEVERAL COOL, DRY
CANADIAN AIR MASSES MOVED INTO THE REGION. JUST AS THE HEAT AND
HUMIDITY WOULD BUILD AGAIN, ANOTHER COLD FRONT WOULD BRING
THUNDERSTORMS AND A FRESH SUPPLY OF COOL, DRY AIR FROM CANADA. A
WARM FRONT WITH TROPICAL MOISTURE FROM DISTANT OFFSHORE TROPICAL
STORM ERIN BROUGHT HEAVY RAIN THE NIGHT OF AUGUST 28 AND 29 WITH
MORE THAN 2 INCHES FALLING, THE HEAVIEST OF THE SUMMER.

THE AVERAGE TEMPERATURE FOR THE SUMMER WAS 68.0 DEGREES WHICH WAS
0.6 DEGREES ABOVE NORMAL BUT THE COOLEST SUMMER SINCE 2015. THE
WARMEST SUMMER WAS 69.2 DEGREES IN 2016 AND 1999. THE COOLEST WAS
65.5 DEGREES IN 2009.

A TOTAL OF 13.16 INCHES OF RAIN FELL WHICH WAS 0.97 INCHES ABOVE
NORMAL. THE HEAVIEST RAIN CAME ON AUGUST 28 AND 29 WHEN 2.02 INCHES
FELL. THE WETTEST SUMMER WAS IN 2009 WHEN 21.77 INCHES WAS RECORDED.
THE DRIEST WAS IN 1999 WITH ONLY 6.92 INCHES.
