AFTER ITS SECOND WARMEST OCTOBER ON RECORD, CONCORD SAW A SHIFT IN
THE WEATHER PATTERN IN THE MONTH OF NOVEMBER. THE FIRST WEEK OF THE
MONTH REMAINED UNSEASONABLY WARM. THE HIGH TEMPERATURE OF 71 DEGREES
ON NOVEMBER 3 WAS THE WARMEST TEMPERATURE IN THE MONTH. THINGS BEGAN
TO CHANGE WHEN A COLD FRONT ON THE 6TH BROUGHT COOLER AIR INTO THE
AREA. ALTHOUGH TEMPERATURES DROPPED TO A FEW DEGREES BELOW NORMAL,
IT WAS JUST A TASTE OF WHAT WAS TO COME. ANOTHER, STRONGER COLD
FRONT BROUGHT MUCH COLDER AIR STRAIGHT OUT OF THE ARCTIC A FEW DAYS
LATER, WITH THE TEMPERATURE DROPPING TO 19 DEGREES ON THE 11TH.
ALTHOUGH THE BRUTAL COLD ONLY LASTED A FEW DAYS, A SERIES OF COLD
FRONTS KEPT TEMPERATURES BELOW NORMAL FOR THE REST OF THE MONTH WITH
ONLY A FEW BRIEF EXCEPTIONS. THE FIRST MEASURABLE SNOW OF THE SEASON
WAS OBSERVED ON THE 13TH WHEN 0.6 INCHES FELL.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 38.0 DEGREES WHICH WAS 0.3
DEGREES BELOW NORMAL AND THE FIRST BELOW NORMAL NOVEMBER SINCE 2014.
THE COLDEST NOVEMBER ON RECORD WAS IN 1873 WHEN THE AVERAGE
TEMPERATURE WAS 28.8 DEGREES. THE WARMEST WAS 43.3 DEGREES IN 2006.

A TOTAL OF 1.35 INCHES OF PRECIPITATION FELL WHICH WAS 2.37 INCHES
BELOW NORMAL. THE HEAVIEST PRECIPITATION WAS ON THE 6TH WHEN 0.40
INCHES FELL. THE DRIEST NOVEMBER ON RECORD ONLY HAD 0.50 INCHES OF
PRECIPITATION IN 2012 AND 1939. THE WETTEST WAS IN 1937 WHEN 7.59
INCHES WAS MEASURED.

ONLY 0.6 INCHES OF SNOW FELL WHICH WAS 2.0 INCHES BELOW NORMAL. ALL
OF THIS SNOW FELL ON THE 13TH. SNOWFALL IN NOVEMBER IS OFTEN
INCONSISTENT. OF THE 150 YEARS OF SNOWFALL RECORDS AT CONCORD, THERE
HAVE BEEN 5 YEARS IN WHICH NO SNOW FELL IN NOVEMBER, MOST RECENTLY
IN 2015. THERE HAVE BEEN AN ADDITIONAL 31 YEARS IN WHICH ONLY A
TRACE OF SNOW WAS OBSERVED, MOST RECENTLY IN 2010. IN ROUGHLY 25
PERCENT OF YEARS MEASURABLE SNOWFALL IS NOT SEEN IN NOVEMBER. THE
SNOWIEST NOVEMBER WAS IN 1873 WHEN 25.0 INCHES FELL.

NO DAILY RECORDS WERE SET OR TIED IN NOVEMBER 2017.
