WARM WEATHER BEGAN TO BUILD AT THE BEGINNING OF OCTOBER WITH ABOVE
NORMAL TEMPERATURES OBSERVED THROUGH THE 9TH. A COLD FRONT BROUGHT
RAIN ON THE 9TH ALONG WITH A FEW DAYS OF COOLER TEMPERATURES.
ANOTHER BRIEF WARM UP CAME FOLLOWED QUICKLY BY ANOTHER COLD FRONT
AND A FEW DAYS OF COOL TEMPERATURES. THIS BACK AND FORTH PATTERN
BEGAN TO SHIFT IN MID OCTOBER WHEN A PROLONGED STRETCH OF MUCH
WARMER WEATHER PERSISTED FROM THE 16TH THROUGH THE 22ND, INCLUDING A
HIGH OF 79 DEGREES ON THE 17TH. ON OCTOBER 21 TROPICAL MOISTURE
SURGED NORTHWARD AHEAD OF A COLD FRONT, BRINGING VERY HEAVY RAINFALL
THAT EVENING. OVER THE COURSE OF JUST A FEW HOURS MORE THAN 3 INCHES
OF RAIN WAS OBSERVED. COOLER AIR MOVED IN BEHIND THE FRONT AND
PERSISTED THROUGH MUCH OF THE REST OF THE MONTH. A NOR`EASTER MOVING
OFFSHORE BROUGHT ANOTHER 2 INCHES OF RAIN ON THE 27TH AND 28TH.
THESE TWO MAJOR RAINSTORMS HELPED PUT A DENT IN THE DROUGHT WHICH
HAD INTENSIFIED THROUGH THE SUMMER AND EARLY FALL.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 50.7 DEGREES WHICH WAS 2.5
DEGREES ABOVE NORMAL. THE WARMEST OCTOBER ON RECORD WAS IN 1879 WHEN
THE AVERAGE TEMPERATURE WAS 57.6 DEGREES. THE COOLEST WAS IN 1925 AT
ONLY 42.2 DEGREES.

A TOTAL OF 6.26 INCHES OF RAIN FELL WHICH WAS 2.22 INCHES ABOVE
NORMAL AND THE WETTEST OCTOBER SINCE 2011. THIS WAS THE FIRST MONTH
OF ABOVE NORMAL PRECIPITATION SINCE FEBRUARY. THE WETTEST OCTOBER
WAS IN 2005 WHEN 14.57 INCHES FELL. THE DRIEST WAS IN 1924 WITH ONLY
0.05 INCHES.

NO SNOW WAS OBSERVED IN OCTOBER 2016. SNOW IS RELATIVELY RARE IN
OCTOBER WITH AT LEAST A TRACE OF SNOW BEING RECORDED IN 52 OF THE
LAST 149 YEARS, MOST RECENTLY IN 2013. MEASURABLE SNOWFALL HAS ONLY
BEEN OBSERVED IN 15 OF THOSE YEARS, MOST RECENTLY IN 2011. THE
SNOWIEST OCTOBER WAS IN 2011 WHEN 23.0 INCHES FELL.
