...OCTOBER WAS WARMER AND WETTER THAN NORMAL IN OMAHA...

THE MONTH OF OCTOBER SAW ABOVE-NORMAL TEMPERATURES COMPARED TO 1981-
2010 CLIMATOLOGY. IT ALSO WAS THE 19TH WETTEST OCTOBER ON RECORD AT
4.06 INCHES. ALMOST ALL OF THE RAIN FELL BETWEEN THE 1ST AND 14TH,
MAKING IT THE 4TH WETTEST SUCH PERIOD ON RECORD AT 3.98 INCHES.
ALSO, A TRACE OF SNOW WAS RECORDED, WHICH TIES WITH 33 OTHER YEARS
FOR THE 25TH MOST SNOW IN OCTOBER ON RECORD (NOTING THAT 1997
SNOWFALL IS MISSING FROM THE OFFICIAL OMAHA RECORDS) AND IS BELOW
THE NORMAL OF 0.3 INCHES.

THE FIRST HALF OF OCTOBER WAS VERY WET AND MOSTLY WARM. FROM THE 1ST
TO 14TH, 9 OF THOSE DAYS RECORDED MEASURABLE RAIN, WITH 7 OF THOSE
ALSO REPORTING THUNDER. TEMPERATURES FROM THE 1ST TO THE 8TH WERE
ABOVE NORMAL, WITH THE WARMEST TEMPERATURE OF THE MONTH ON THE 2ND
AT 84 DEGREES AND WITH MOST DAYS IN THE 70S OR 80S. A BRIEF COOL-
DOWN FROM THE 9TH TO 11TH BROUGHT A RELATIVELY COOL HIGH IN THE 40S
ON THE 10TH, WITH ABOVE-NORMAL TEMPERATURES RETURNING ON THE 12TH TO
14TH.

CONDITIONS TURNED MUCH DRIER FOR THE END OF THE MONTH - A WELCOME
DRYNESS, ALLOWING FIELD CONDITIONS TO DRY FOR HARVEST IN THE AREA.
TEMPERATURES ON THE 15TH WERE SLIGHTLY BELOW NORMAL, WITH ABOVE-
NORMAL TEMPERATURES ON ALL BUT ONE DAY FROM THE 16TH TO THE 26TH,
INCLUDING SEVERAL DAYS IN THE MID TO UPPER 70S. THE LAST (LIGHT)
RAINFALL OF THE MONTH, WITH THUNDER, FELL ON THE 21ST. A
PARTICULARLY WINDY SET OF DAYS INCLUDED THE 20TH (43 MPH), 23RD (47
MPH), 26TH (50 MPH), AND 27TH (43 MPH). THE STRONG COLD FRONT ON THE
26TH BROUGHT MUCH COLDER TEMPERATURES ALONG WITH THE GUSTY WINDS.
THE HIGH TEMPERATURE ON THE 27TH REACHED JUST 38 DEGREES, MATCHING
THE LOW TEMPERATURE ON THE 26TH PRECEDING IT. TEMPERATURES ON THE
EVENING OF THE 27TH BEGAN A PLUNGE THAT CONTINUED INTO THE MORNING
OF THE 28TH. THIS PRODUCED THE FIRST FREEZE OF THE YEAR, AS WELL AS
A HARD FREEZE, ON THE 27TH (IN THE EVENING), WITH THE LOW REACHING
20 DEGREES ON THE MORNING OF THE 28TH. TEMPERATURES REBOUNDED
BRIEFLY ON THE 29TH, WITH COOL READINGS ON THE 30TH (WITH BRISK 45-
MPH WINDS) AND ESPECIALLY ON THE 31ST. OMAHA AREA TRICK-OR-TREATERS
WERE GREETED WITH PERSISTENT SNOW FLURRIES IN THE EVENING ON THE
31ST, WITH A LOW OF 23 IN THE MORNING AND A HIGH OF JUST 38 IN THE
AFTERNOON.
