SUMMER WARMTH CONTINUED THRU THE MIDDLE OF SEPTEMBER WITH THE
TEMPERATURE REACHING 80 DEGREES OR WARMER FOR 15 OF THE FIRST 22
DAYS OF SEPTEMBER. APART FROM A LOCALIZED THUNDERSTORM WHICH DROPPED
MORE THAN 2 INCHES OF RAIN ON SEPTEMBER 19, DRY WEATHER DOMINATED
WITH DROUGHT INTENSIFYING INTO THE FALL. THE SUMMER WARMTH WAS
EVENTUALLY PUSHED ASIDE AS COOLER AIR MOVED IN FOR THE FINAL WEEK OF
SEPTEMBER. THE FIRST FREEZE OF THE SEASON OCCURRED ON SEPTEMBER 26
WHICH WAS NEAR THE NORMAL DATE OF FIRST FREEZE. THIS COOLER WEATHER
DID NOT LAST TOO LONG AS THE WARMTH BEGAN TO BUILD AGAIN THROUGH MID
OCTOBER. ON OCTOBER 21 TROPICAL MOISTURE SURGED NORTHWARD AHEAD OF
AN APPROACHING COLD FRONT LEADING TO VERY HEAVY RAINFALL. MORE THAN
3 INCHES OF RAIN FELL IN JUST A FEW HOURS THAT EVENING. GRADUALLY
COOLER AIR BEGAN MOVING IN BEHIND THIS SYSTEM. ANOTHER SIGNIFICANT
RAINSTORM ARRIVED ON OCTOBER 28TH, HELPING TO PUT A DENT IN THE
PERSISTENT DROUGHT. AFTER A COUPLE OF BRIEF PERIODS OF COOLER
WEATHER, THE WARM WEATHER BEGAN BUILDING AGAIN INTO THE MIDDLE OF
NOVEMBER WITH SEVERAL DAYS OF TEMPERATURES IN THE 60S. THIS CAME TO
AN END ON NOVEMBER 20 WHEN COLDER AIR ARRIVED ALONG WITH THE FIRST
MEASURABLE SNOWFALL OF THE SEASON.
