...OCTOBER WAS WARMER AND MUCH WETTER THAN NORMAL IN LINCOLN...

THE MONTH OF OCTOBER SAW ABOVE-NORMAL TEMPERATURES COMPARED TO 1981-
2010 CLIMATOLOGY. IT ALSO WAS THE 4TH WETTEST OCTOBER ON RECORD AT
4.90 INCHES. ALMOST ALL OF THE RAIN FELL BETWEEN THE 1ST AND 14TH,
MAKING IT THE WETTEST SUCH PERIOD ON RECORD AT 4.89 INCHES. ALSO, A
TRACE OF SNOW WAS RECORDED, WHICH TIES WITH 16 OTHER YEARS FOR THE
11TH MOST SNOW IN OCTOBER ON RECORD (NOTING THAT LINCOLN SNOWFALL
RECORDS BEGIN IN 1948) AND IS BELOW THE NORMAL OF 0.7 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 8 OF THOSE
ALSO REPORTING THUNDER. THREE OF THOSE DAYS SAW RAINFALL AMOUNTS
OVER AN INCH. 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 THE FIRST FREEZE OF THE SEASON ON THE 11TH,
AT 30 DEGREES, 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 FROM THE 16TH TO THE 26TH, INCLUDING SEVERAL
DAYS IN THE MID 70S TO 80 DEGREES. THE LAST RAINFALL OF THE MONTH,
WITH THUNDER, FELL ON THE 21ST.  A PARTICULARLY WINDY SET OF DAYS
INCLUDED THE 20TH (49 MPH), 21ST (41 MPH), 23RD (50 MPH), AND 26TH
(45 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 41 DEGREES. 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 ON THE 28TH, WITH THE LOW
REACHING 22 DEGREES IN THE MORNING. TEMPERATURES REBOUNDED BRIEFLY
ON THE 29TH, WITH COOL READINGS ON THE 30TH (WITH BRISK 41-MPH
WINDS) AND ESPECIALLY ON THE 31ST. HALLOWEEN BEGAN WITH SNOW IN THE
MORNING TO EARLY AFTERNOON, WITH JUST A TRACE AT LINCOLN AIRPORT BUT
ACCUMULATIONS UP TO AROUND 0.5-1 INCHES ELSEWHERE AROUND THE CITY.
TRICK-OR-TREATERS FACED BRISK CONDITIONS, AS THE HIGH TEMPERATURE ON
THE 31ST WAS JUST 36 DEGREES.


DAILY RECORDS SET IN OCTOBER 2017:
