PATTERN WITH A FEW DAYS OF ABOVE NORMAL WEATHER FOLLOWED BY A COLD
FRONT AND COOLER WEATHER. BY THE MIDDLE OF THE MONTH WARM WEATHER
BEGAN TO DOMINATE. THE TEMPERATURE REACHED 50 DEGREES OR HIGHER FOR
8 STRAIGHT DAYS FROM THE 13TH THROUGH THE 20TH INCLUDING 3 DAYS OF
60 DEGREES OR MORE. A STORM SYSTEM BROUGHT MORE THAN AN INCH OF RAIN
ON THE 15TH AND 16TH AND COMBINED WITH THE HIGHEST ASTRONOMICAL TIDE
IN DECADES TO PRODUCE MINOR COASTAL FLOODING. THE FIRST SNOWFALL OF
THE SEASON CAME ON THE NIGHT OF THE 20TH INTO THE MORNING OF THE
21ST WHEN 0.5 INCHES OF SNOW WAS MEASURED. ALTHOUGH THE SNOW WAS
LIGHT, IT WAS A SIGN OF A SHIFT IN THE WEATHER PATTERN AS THE
PERSISTENT WARM WEATHER CAME TO AN END. COOLER THAN NORMAL WEATHER
WAS THE RULE FOR THE REST OF NOVEMBER. ANOTHER STORM SYSTEM BROUGHT
MORE THAN AN INCH OF RAIN ON THE 29TH AND 30TH, HELPING TO KEEP THE
PERSISTENT DROUGHT FROM INTENSIFYING.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 41.5 DEGREES WHICH WAS 2.1
DEGREES ABOVE NORMAL. THE WARMEST NOVEMBER ON RECORD WAS 2011 WHEN
THE AVERAGE TEMPERATURE WAS 44.7 DEGREES. THE COLDEST WAS IN 1967 AT
ONLY 34.7 DEGREES.
