THE FALL STARTED OFF ON A WARM NOTE AS A FAMILIAR WEATHER PATTERN
CONTINUED. A RIDGE OF HIGH PRESSURE OVER THE EAST COAST AND WESTERN
ATLANTIC KEPT A FREQUENT FLOW OF WARM, HUMID AIR MASSES AROUND IT
AND INTO NEW ENGLAND. THERE WERE BRIEF PERIODS OF COOLER WEATHER
BEHIND OCCASIONAL COLD FRONTS ALONG WITH INFREQUENT STORMS WHICH
BROUGHT HEAVY RAINFALL, BUT OVERALL THE WARM WEATHER CONTINUED DEEP
INTO OCTOBER. THE TEMPERATURE PEAKED AT 83 DEGREES ON OCTOBER 10,
BUT THIS WAS THE LAST OF THE WARM WEATHER. A COLD FRONT MOVED
THROUGH THAT DAY AND THE TEMPERATURE TOOK A TUMBLE AND THE
PERSISTENT WEATHER PATTERN BEGAN TO CHANGE. A TROUGH DEVELOPED OVER
THE EASTERN UNITED STATES BRINGING SEVERAL ROUNDS OF COLD AIR INTO
THE AREA. BEING FREQUENTLY ON THE EASTERN SIDE OF THIS TROUGH MEANT
THAT STORM SYSTEMS EXITING THE COUNTRY FREQUENTLY PASSED NEAR NEW
ENGLAND BRINGING NEW PRECIPITATION EVERY FEW DAYS. JUST AS THE
TEMPERATURE STARTED TO DRIFT BACK TOWARD NORMAL, TWO SIGNIFICANT
WAVES OF ARCTIC AIR MOVED INTO THE REGION IN MID NOVEMBER. THE FIRST
ARRIVED WITH A COLD FRONT ON NOVEMBER 13 THAT BROUGHT 1 INCH OF RAIN
AND PLUNGING TEMPERATURES. THE TEMPERATURE DID NOT EVEN WARM OUT OF
THE 20S ON NOVEMBER 15 AND 16, ABOUT TWO WEEKS EARLIER THAN
AUGUSTA`S AVERAGE FIRST SUBFREEZING DAY. SOON SNOW BEGAN TO FALL AS
WELL AND ANOTHER STRONG ARCTIC AIR MASS ARRIVED JUST IN TIME FOR
THANKSGIVING. AFTER DROPPING TO 4 DEGREES ON THANKSGIVING MORNING,
NOVEMBER 22, THE TEMPERATURE ONLY WARMED TO 14 THAT AFTERNOON. THIS
WAS THE COLDEST FALL DAY ON RECORD AT AUGUSTA. THE TEMPERATURE
GRADUALLY MODERATED BACK TOWARD NORMAL BY THE END OF NOVEMBER WITH
MORE SNOW AND RAIN.

THE AVERAGE TEMPERATURE FOR THE FALL WAS 46.9 DEGREES WHICH WAS 1.9
DEGREES BELOW NORMAL AND THE 9TH COLDEST FALL ON RECORD AT AUGUSTA.
THE COLDEST FALL WAS IN 1974 WHEN THE AVERAGE TEMPERATURE WAS 45.2
DEGREES. THE WARMEST WAS JUST LAST YEAR WHEN  THE AVERAGE
TEMPERATURE WAS 52.6 IN 2017. THE FOLLOWING TABLE LISTS THE COLDEST
