THE FALL BEGAN WITH A SERIES OF COOL, DRY AIR MASSES MOVING OUT OF
CANADA. THIS BROUGHT MANY COOL DAYS AND EVEN COOLER NIGHTS. THE
COOLEST TEMPERATURE OF THIS STRETCH WAS 41 DEGREES ON SEPTEMBER 19.
BUT THEN SUMMER-LIKE WARMTH MADE A QUICK COMEBACK. HEAT WHICH HAD
BEEN BUILDING OVER THE SOUTHEAST US SPILLED INTO NEW ENGLAND WITH
THE NEXT 5 DAYS SEEING TEMPERATURES IN THE UPPER 70S AND LOW 80S.
AFTER THIS LATE SEASON WARM UP, THE TREND OF COOL, DRY AIR MASSES
COMING OUT OF CANADA RETURNED FOR THE NEXT FEW WEEKS. THIS TIME THE
TEMPERATURE BOTTOMED OUT AT 37 DEGREES ON OCTOBER 3, 4, AND 5. SOON
THE PATTERN CHANGED AGAIN WITH A LARGE UPPER TROUGH DEVELOPING OVER
THE CENTER OF THE COUNTRY. THIS ALLOWED WARM, MOIST AIR TO MOVE
TOWARD NEW ENGLAND ALONG WITH MORE FREQUENT RAINFALL. THE CLOUDS AND
RAIN BROUGHT MANY COOL DAYS AND WARM NIGHTS. A SERIES OF STORM
SYSTEMS BEGAN AFFECTING THE AREA IN LATE OCTOBER. THE FIRST WAS ON
OCTOBER 17 WITH MORE THAN AN INCH OF RAIN ALONG WITH STRONG WINDS.
THE NEXT CAME A WEEK LATER WITH NEARLY 2 INCHES OF RAIN ON OCTOBER
22 AND 23. ANOTHER INCH FELL ON OCTOBER 27. THE LAST BROUGHT RAIN ON
HALLOWEEN. STRONG WINDS BLEW BEHIND THIS SYSTEM WITH THE LAST WARM
DAY OF THE FALL COMING ON NOVEMBER 1 AT 64 DEGREES. THE FIRST FREEZE
CAME A DAY LATER. EVEN COLDER AIR MOVED IN ON NOVEMBER 7 WITH MUCH
OF THE NEXT TWO WEEKS SEEING TEMPERATURES 10 TO 15 DEGREES BELOW
NORMAL. THE FIRST ACCUMULATING SNOW OF THE SEASON CAME ON NOVEMBER
11 AND COLD TEMPERATURES ALLOWED THIS TO STICK AROUND FOR MORE THAN
A WEEK. GRADUALLY, THOUGH, THE TEMPERATURE DRIFTED BACK TOWARD
NORMAL AND THE LAST FEW STORM SYSTEMS BROUGHT MOSTLY RAIN.

THE AVERAGE TEMPERATURE FOR THE FALL WAS 48.3 DEGREES WHICH WAS 1.0
DEGREES BELOW NORMAL. THE COOLEST FALL WAS JUST LAST YEAR WHEN THE
AVERAGE TEMPERATURE WAS 47.2 DEGREES. THE WARMEST WAS THE YEAR
BEFORE THAT WHEN IT WAS 53.0 DEGREES IN 2017.

A TOTAL OF 10.41 INCHES OF PRECIPITATION FELL WHICH WAS 4.27 INCHES
BELOW NORMAL AND THE DRIEST FALL SINCE 2012. THE HEAVIEST
PRECIPITATION CAME ON OCTOBER 22 AND 23 WHEN 1.97 INCHES OF RAIN WAS
RECORDED. THE DRIEST FALL WAS IN 2001 WHEN ONLY 8.91 INCHES WAS
MEASURED. THE WETTEST WAS IN 2005 WITH 26.48 INCHES.

THERE WAS 0.7 INCHES OF SNOWFALL WHICH WAS 2.4 INCHES BELOW NORMAL.
ALL OF THIS FELL ON NOVEMBER 11 AND 12. SNOW IN FALL IS QUITE
VARIABLE WITH MOST OF IT FALLING IN THE LAST HALF OF NOVEMBER JUST
AS THE SNOW SEASON IS GETTING STARTED. THE SNOWIEST FALL WAS IN 1997
WHEN 23.9 INCHES FELL. THERE HAVE BEEN 4 FALLS THAT ONLY SAW A TRACE
OF SNOWFALL, MOST RECENTLY IN 2006.
