NOVEMBER WAS COOLER AND DRIER THAN NORMAL ACROSS NORTHERN NEW
ENGLAND. IF IT WAS NOT FOR AN AREA OF LOW PRESSURE BRINGING 1.84
INCHES OF RAIN TO PORTLAND ON THE 22ND, PRECIPITATION WOULD HAVE
BEEN WELL BELOW NORMAL. THERE WERE ONLY SIX DAYS OF THE MONTH WHERE
PORTLAND RECEIVED MEASURABLE PRECIPITATION. MUCH OF THE MONTH
FEATURED DAYS WHERE TEMPERATURES RAN BELOW NORMAL OR WERE CLOSE TO
NORMAL WHILE THERE WERE NOT ANY NOTABLE WARM SPELLS. THE DOMINANT
PATTERN THROUGH THE MONTH WAS A TROUGH OF LOW PRESSURE OVER HUDSON
BAY EXTENDING ACROSS NEW ENGLAND WITH A RIDGE OF HIGH PRESSURE OVER
WESTERN CANADA. THE TROUGH AXIS OVER NEW ENGLAND WAS OFTEN TOO FAR
EAST LIMITING THE POTENTIAL FOR MOISTURE TO BE DRAWN INTO NEW
ENGLAND. THEREFORE, DESPITE BELOW NORMAL TEMPERATURES THERE OFTEN
WAS NOT ENOUGH MOISTURE AROUND LEADING TO PORTLAND ONLY SEEING A
COUPLE DAYS OF SNOW FLURRIES AND NO MEANINGFUL SNOW EVENTS.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 37.0 DEGREES, WHICH WAS
3.0 DEGREES BELOW NORMAL. THE COLDEST NOVEMBER ON RECORD WAS IN 1967
WHEN THE AVERAGE TEMPERATURE WAS 34.7 DEGREES. THE WARMEST WAS 44.7
DEGREES IN 2011.

A TOTAL OF 3.20 INCHES OF PRECIPITATION FELL, WHICH WAS 1.05 INCHES
BELOW NORMAL. THE HEAVIEST PRECIPITATION FELL ON THE 22ND WHEN 1.84
INCHES WAS RECORDED. THE DRIEST NOVEMBER ON RECORD WAS IN 1939 WHEN
ONLY 0.56 INCHES FELL. THE WETTEST WAS 13.50 INCHES IN 1983.

A TOTAL OF 0.2 INCHES OF SNOW FELL, WHICH WAS 2.1 INCHES BELOW
NORMAL. THERE HAVE BEEN 7 YEARS ON RECORD WHERE NO SNOW FELL AT
PORTLAND DURING NOVEMBER WITH THE MOST RECENT OCCURRING IN 2006. THE
SNOWIEST NOVEMBER ON RECORD WAS 24.3 INCHES IN 1921.

THE FOLLOWING DAILY RECORDS WERE SET OR TIED IN NOVEMBER 2023...
