...APRIL 2013 NARRATIVE FOR CENTRAL NEBRASKA REGIONAL AIRPORT...

APRIL 2013 WILL LIKELY BE MOST REMEMBERED FOR A PRONOUNCED STRETCH
OF WELL-BELOW NORMAL TEMPERATURES...THAT ESPECIALLY DOMINATED THE
MIDDLE TWO WEEKS OF THE MONTH. IN FACT...APRIL 2013 NOT ONLY
AVERAGED ABOUT 10 DEGREES COLDER THAN APRIL 2012...BUT AVERAGED
EIGHT DEGREES COOLER THAN THE INCREDIBLY WARM MARCH OF 2012. WITH
BOTH MARCH AND APRIL OF 2013 FEATURING BELOW NORMAL TEMPS...THIS WAS
THE FIRST INSTANCE OF BACK-TO-BACK BELOW NORMAL MONTHS SINCE
APRIL-MAY 2011. PRECIPITATION-WISE...THE MONTH WAS VERY
BENEFICIAL...WITH GRAND ISLAND RECEIVING ITS MOST PRECIPITATION IN A
CALENDAR MONTH SINCE JULY 2011. IN FACT...ACCORDING TO THE U.S.
DROUGHT MONITOR...A SLIGHT IMPROVEMENT IN DROUGHT CLASSIFICATION
FROM THE EXCEPTIONAL TO THE EXTREME CATEGORY OCCURRED DURING THE
MONTH IN THE IMMEDIATE GRAND ISLAND AREA.

FOCUSING ON PRECIPITATION AND SNOWFALL IN MORE DETAIL...THE MONTHLY
PRECIPITATION TOTAL OF 3.83 INCHES AT CENTRAL NEBRASKA REGIONAL
AIRPORT WAS 1.30 INCHES ABOVE THE APRIL NORMAL OF 2.53 INCHES. THIS
RANKED AS THE 24TH-WETTEST APRIL ON RECORD OUT OF 118 YEARS...AND
THE WETTEST SINCE 4.62 INCHES IN 2007. THE OVERALL WETTEST CALENDAR
DAY OF THE MONTH WAS THE 9TH WITH 1.51 INCHES...WHICH SET A DAILY
RECORD AND INCLUDED VARIOUS PRECIPITATION TYPES INCLUDING
RAIN...HAIL...SLEET AND FREEZING RAIN. ALL MEASURABLE PRECIPITATION
DURING THE MONTH FELL BETWEEN THE 7TH-22ND...WITH BOTH THE FIRST AND
LAST WEEKS FEATURING PREDOMINANTLY DRY CONDITIONS. SNOWFALL TOTALED
6.9 INCHES FOR THE MONTH...A NOTABLE 5.4 INCHES ABOVE THE APRIL
NORMAL OF 1.5 INCHES. THIS RANKED AS THE 9TH-SNOWIEST APRIL ON
RECORD OUT OF 118 YEARS...AND THE SNOWIEST SINCE 7.3 INCHES IN 2003.
THE HIGHEST CALENDAR DAY SNOWFALL OF 4.0 INCHES FELL ON THE
18TH...SETTING A RECORD FOR THE DATE.

TEMPERATURE-WISE...THE MONTHLY MEAN TEMPERATURE RESULTING FROM
AVERAGING BOTH THE HIGHS AND LOWS WAS 46.1 DEGREES...4.5 DEGREES
BELOW THE APRIL NORMAL. THIS RESULTED IN THE 13TH-COLDEST APRIL ON
RECORD OUT OF 118 YEARS...AND THE COLDEST SINCE 1997. IF NOT FOR A
PRONOUNCED WARM-UP DURING THE LAST WEEK OF THE MONTH...APRIL 2013
MIGHT HAVE THREATENED THE TOP-5 COLDEST. A PRONOUNCED SPRING CHILL
DOMINATED THE MAJORITY OF THE MONTH...AS 18 OF THE 30 DAYS FEATURED
A BELOW NORMAL MEAN TEMPERATURE...INCLUDING 15 OF 17 DAYS BETWEEN
THE 9TH-25TH. IN FACT...FOUR OF THESE DAYS EITHER SET OR TIED DAILY
RECORDS FOR COLDEST HIGH TEMPERATURE WITH HIGHS ONLY CLIMBING
BETWEEN 31-43 DEGREES (THE 10TH...18TH...22ND AND 23RD). ONE OF THE
MOST NOTABLE TEMPERATURE TIDBITS OF THE MONTH WAS THAT 18 DAYS
FEATURED LOW TEMPERATURES OF 32 DEGREES OR COLDER...THE 3RD-MOST IN
APRIL OUT OF 118 YEARS...TRAILING ONLY 1904 AND 1950 WHICH HAD 19
DAYS. ALONG THESE SAME LINES...12 DAYS FEATURED HIGH TEMPERATURES
LESS THAN OR EQUAL TO 50 DEGREES...TIED FOR THE 3RD-MOST IN APRIL
OUT OF 118 YEARS...BEHIND 16 DAYS IN 1920 AND 14 DAYS IN 1944. BY
FAR THE WARMEST STRETCH OF THE MONTH WAS THE FINAL SIX DAYS...WHICH
FEATURED HIGH TEMPERATURES BETWEEN 73-86 DEGREES. THE WARMEST HIGH
OF THE MONTH WAS 86 DEGREES ON THE 28TH...WHICH ALSO MARKED THE
FIRST 80+ DEGREE READING OF THE YEAR. FOR LOW TEMPERATURES...THE
COLDEST READING WAS 23 DEGREES ON THE 1ST...AND THE MILDEST LOW WAS
53 DEGREES ON THE 29TH.

ALTHOUGH NO SIGNIFICANT SEVERE THUNDERSTORMS AFFECTED THE IMMEDIATE
GRAND ISLAND AREA DURING THE MONTH...THERE WERE A FEW REPORTS OF
HAIL RANGING FROM NICKEL TO GOLF BALL SIZE WITHIN SEVERAL MILES OF
THE CITY ON THE 9TH. THE HIGHEST WIND GUST OF THE MONTH AT CENTRAL
NEBRASKA REGIONAL AIRPORT...55 MPH FROM THE NORTHEAST...OCCURRED
AROUND 2 AM ON THE 9TH...IN ASSOCIATION WITH A VERY STRONG COLD
FRONT AND THUNDERSTORMS IN THE AREA.
