SUMMER-LIKE WARMTH CONTINUED THROUGH MUCH OF SEPTEMBER. THE NATIONAL
WEATHER SERVICE OFFICE IN GRAY RECORDED ITS DRIEST SEPTEMBER IN ITS
SHORT 21-YEAR HISTORY, LEADING TO INTENSIFYING DROUGHT. THE WARM
WEATHER PATTERN FINALLY BROKE ON SEPTEMBER 23 WHEN A COLD FRONT
MOVED THROUGH THE REGION USHERING IN A COOLER AIR MASS. A MORE
TYPICAL FALL-LIKE WEATHER PATTERN EMERGED WITH ALTERNATING PERIODS
OF WARMER AND COOLER WEATHER AS A SERIES OF COLD FRONTS MOVED
THROUGH THE REGION. BY THE MIDDLE OF OCTOBER, WARMER WEATHER BEGAN
TO DOMINATE AGAIN, WITH A FEW MORE DAYS IN THE 70S. ON OCTOBER 21
TROPICAL AIR SURGED NORTHWARD AHEAD OF AN APPROACHING COLD FRONT AND
LED TO VERY HEAVY RAINFALL. MORE THAN 4 INCHES OF RAIN FELL IN JUST
A FEW HOURS ON THE EVENING OF OCTOBER 21 INTO THE 22ND. THIS FRONTAL
PASSAGE ALSO SIGNALED A SHIFT IN THE WEATHER PATTERN WITH COOLER
WEATHER LASTING THROUGH THE END OF THE MONTH. MORE HEAVY RAIN FELL
ON OCTOBER 28, HELPING TO PUT A DENT IN THE DROUGHT WHICH HAD
INTENSIFIED THROUGH THE SUMMER AND EARLY FALL. WARMER WEATHER BEGAN
TO BUILD BACK INTO THE AREA IN MID NOVEMBER, BUT A STORM SYSTEM
MOVING THROUGH THE AREA ON NOVEMBER 20 AND 21 BROUGHT COLDER AIR IN
AGAIN ALONG WITH THE FIRST ACCUMULATING SNOWFALL OF THE SEASON.
ANOTHER STORM SYSTEM ON NOVEMBER 29 BROUGHT LIGHT FREEZING RAIN AND
RAIN AS THE FALL CAME TO A CLOSE.

THE AVERAGE TEMPERATURE FOR THE FALL WAS 51.8 DEGREES WHICH WAS 2.5
DEGREES ABOVE NORMAL. THE WARMEST FALL ON RECORD WAS IN 2011 WHEN
THE AVERAGE TEMPERATURE WAS 52.4 DEGREES. THE COOLEST WAS IN 1997
WHEN THE AVERAGE TEMPERATURE WAS ONLY 47.3 DEGREES.

A TOTAL OF 13.20 INCHES OF PRECIPITATION FELL WHICH WAS 1.48 INCHES
BELOW NORMAL. MORE THAN HALF OF THIS PRECIPITATION FELL DURING TWO
HEAVY RAINSTORMS IN LATE OCTOBER. THE WETTEST FALL ON RECORD WAS IN
2005 WHEN 26.48 INCHES WAS MEASURED. THE DRIEST WAS IN 2001 WITH
ONLY 8.91 INCHES.

THERE WAS A TOTAL OF 1.3 INCHES OF SNOW WHICH WAS 1.8 INCHES BELOW
NORMAL. MOST OF THIS SNOW FELL ON NOVEMBER 20 AND 21. FALL SNOWFALL
IS QUITE VARIABLE, WITH MEASURABLE SNOW BEING OBSERVED ABOUT 82
PERCENT OF THE TIME. THE MOST FALL SNOWFALL WAS IN 1997 WHEN 23.9
INCHES WAS RECORDED. THERE HAVE BEEN 4 YEARS WHEN ONLY A TRACE OF
SNOW WAS OBSERVED IN FALL, MOST RECENTLY IN 2006.
