...DECEMBER 2014 NARRATIVE FOR CENTRAL NEBRASKA REGIONAL AIRPORT...

ALTHOUGH THE MONTH AS A WHOLE AVERAGED SLIGHTLY ABOVE NORMAL IN THE
TEMPERATURE...PRECIPITATION AND SNOWFALL DEPARTMENTS...THE TWO MOST
MEMORABLE ASPECTS OF THE MONTH WERE:

1) AN UNUSUALLY LONG-STRETCH OF CLOUDY "WINTER GLOOM" THAT HUNG OVER
THE AREA FOR ESSENTIALLY TWO STRAIGHT WEEKS DURING THE MIDDLE PART
OF THE MONTH. IN FACT...GRAND ISLAND SAW VERY LITTLE (IF ANY)
SUNSHINE FOR TWO CONSECUTIVE WEEKS BETWEEN THE 10TH AND
23RD...BEFORE THE SUN MADE A TRIUMPHANT RETURN JUST IN TIME FOR
CHRISTMAS EVE-CHRISTMAS DAY.

2) THROUGH THE FIRST 26 DAYS OF THE MONTH...DECEMBER WAS ON PACE TO
BE ONE OF THE TOP-15 WARMEST ON RECORD WITH AN AVERAGE TEMPERATURE
THAT WAS 6.1 DEGREES ABOVE NORMAL. HOWEVER...A NOTICEABLY COLDER
AIRMASS SETTLED INTO THE AREA DURING THE FINAL 5 DAYS AND ESPECIALLY
THE LAST TWO DAYS...THUS KNOCKING THE MONTHLY AVERAGE TEMPERATURE
DOWN SEVERAL DEGREES FROM ITS INITIAL PACE.

FOCUSING ON TEMPERATURES IN MORE DETAIL...THE OVERALL AVERAGE
MONTHLY TEMPERATURE (RESULTING FROM AVERAGING BOTH THE HIGHS AND
LOWS) WAS 29.1 DEGREES...WHICH WAS 2.4 DEGREES ABOVEN NORMAL. AS
MENTIONED IN THE PRECEDING PARAGRAPH...THE MAJORITY OF THE MONTH WAS
SEASONABLY MILD...AS 21 OF THE FIRST 26 DAYS CARRIED AN ABOVE NORMAL
AVERAGE TEMPERATURE. HOWEVER...NOTICEABLY COLDER AIR ARRIVED DURING
THE FINAL 5 DAYS...PEAKING IN INTENSITY ON THE 30TH-31ST AS LOW
TEMPERATURES BOTTOMED OUT AT -8 AND -7 DEGREES...RESPECTIVELY.
FURTHERMORE..THE HIGH OF ONLY 4 DEGREES ON THE 30TH MARKED THE
COLDEST HIGH TEMPERATURE FOR THE ENTIRE YEAR OF 2014. DURING THE
MILD MAJORITY OF THE MONTH...THE OVERALL-WARMEST WEEK WAS CENTERED
BETWEEN THE 8TH-14TH DURING WHICH FOUR OF THE SEVEN DAYS REACHED AT
LEAST 51 DEGREES...INCLUDING THE WARMEST MONTHLY HIGH OF 58 ON THE
14TH. HOWEVER...MILD LOW TEMPERATURES STOLE THE SPOTLIGHT ON THE
12TH AND 13TH...AS NOT ONLY DID BOTH DAYS SET NEW RECORD WARM LOWS
FOR THE DATE...BUT THE LOW OF ONLY 47 DEGREES ON THE 13TH SET A NEW
RECORD-WARMEST LOW FOR THE ENTIRE MONTH OF DECEMBER! THIS VALUE
ECLIPSED THE PREVIOUS MARK OF 46 DEGREES WHICH WAS INITIALLY SET ON
DEC. 3-4, 1913 AND THEN MATCHED ON DEC. 1, 1998. THE MOST EXTREME
DAY-TO-DAY CHANGE IN HIGH TEMPERATURES DURING THE MONTH WAS 27
DEGREES AND OCCURRED EARLY-ON...CONSISTING OF A SHARP WARM-UP FROM
25 DEGREES ON THE 1ST TO 52 ON THE 2ND.

TURNING TO DECEMBER 2014 PRECIPITATION...THE TOTAL OF 0.76 INCHES AT
CENTRAL NEBRASKA REGIONAL AIRPORT WAS 0.13 INCHES ABOVE THE 30-YEAR
NORMAL OF 0.63 INCHES. OVER HALF OF THIS PRECIPITATION (0.42 INCHES)
FELL IN THE FORM OF RAIN ON THE 14TH-15TH. THEN DURING THE LATTER
HALF OF THE MONTH...GRAND ISLAND RECEIVED FOUR FAIRLY "MINOR" ROUNDS
OF ACCUMULATING SNOW...THE MOST SIGNIFICANT OF WHICH WAS 3.5 INCHES
THAT FELL BETWEEN THE EVENING OF THE 26TH AND THE EARLY MORNING OF
THE 27TH. DESPITE ONLY BEING 3.5 INCHES...THIS WAS ACTUALLY THE
SINGLE-BIGGEST SNOW "EVENT" OF THE YEAR 2014. TOTAL SNOWFALL FOR THE
MONTH ENDED UP AT 5.9 INCHES...ONLY 0.8 INCHES ABOE THE 30-YEAR
NORMAL.

NO THUNDERSTORMS AFFECTED GRAND ISLAND DURING THE MONTH.
FURTHERMORE...IT WAS NOT ON OVERLY-WINDY DECEMBER AS ONLY THREE DAYS
FEATURED PEAK NORTH-NORTHWESTERLY GUSTS OF 40+ MPH...LED BY A 49 MPH
GUST ON THE 15TH.
