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

MAY 2013 WAS THE WETTEST MONTH IN EXACTLY TWO YEARS...SINCE MAY
2011. IN FACT...THE ABOVE NORMAL PRECIPITATION IN BOTH APRIL AND MAY
MARKED THE FIRST BACK-TO-BACK MONTHS OF ABOVE NORMAL PRECIPITATION
SINCE APRIL-MAY 2011. THANKS TO THIS RECENT WET PATTERN...A FAIRLY
SIGNIFICANT IMPROVEMENT IN DROUGHT CONDITIONS OCCURRED DURING THE
MONTH...AS GRAND ISLAND WENT FROM THE EXTREME D3 CLASSIFICATION TO
THE MODERATE D1 CATEGORY. TEMPERATURE-WISE...THE MONTH STARTED QUITE
CHILLY...BUT REBOUNDED TO SLIGHTLY ABOVE NORMAL IN THE END.

FOCUSING ON PRECIPITATION AND SNOWFALL IN MORE DETAIL...THE MONTHLY
PRECIPITATION TOTAL OF 6.77 INCHES AT CENTRAL NEBRASKA REGIONAL
AIRPORT WAS 2.36 INCHES ABOVE THE MAY NORMAL OF 4.41 INCHES. THIS
RANKED AS THE 15TH-WETTEST MAY ON RECORD OUT OF 118 YEARS...ALTHOUGH
IT WAS NOT AS WET AS TWO YEARS AGO IN MAY 2011 (8.70 INCHES). THE
OVERALL WETTEST CALENDAR DAY OF THE MONTH WAS THE 25TH WITH 2.82
INCHES...MOST OF WHICH FELL DURING THE PRE-DAWN HOURS AND SET A
RECORD FOR THE DATE. INCREDIBLY...THE 24-HOUR RAINFALL TOTAL OF 3.09
INCHES THAT FELL FROM THE 24TH-25TH WAS MORE THAN ALL CUMULATIVE
RAIN THAT FELL DURING THE FOUR-MONTH PERIOD BETWEEN JUNE-SEPTEMBER
2012 (2.84 INCHES). SNOWFALL TOTALED 0.7 INCHES FOR THE MONTH...ALL
OF WHICH FELL ON THE 1ST. THIS WAS NOT ONLY A DAILY RECORD...BUT
MORE NOTABLY...WAS THE FIRST MAY MEASURABLE SNOW IN GRAND ISLAND
SINCE 4.3 INCHES ON MAY 3, 1967...46 YEARS AGO.

TEMPERATURE-WISE...THE MONTHLY MEAN TEMPERATURE RESULTING FROM
AVERAGING BOTH THE HIGHS AND LOWS WAS 61.5 DEGREES...ONLY 0.3
DEGREES ABOVE THE MAY NORMAL AND THUS NOT A VERY SIGNIFICANT
DEPARTURE. OF THE 31 DAYS DURING THE MONTH...18 DAYS FEATURED AN
ABOVE NORMAL MEAN TEMPERATURE...12 DAYS WERE BELOW NORMAL...AND ONE
DAY TIED THE DAILY NORMAL. HOWEVER...THE MONTH STARTED OFF QUITE
COLD WITH AVERAGE TEMPERATURES ON EACH OF THE FIRST FOUR DAYS
SOMEWHERE BETWEEN 11-16 DEGREES BELOW NORMAL. TWO OF THESE
DAYS...THE 1ST AND THE 4TH...ONLY REACHED 47 DEGREES...MARKING THE
COLDEST HIGH TEMPERATURES OF THE MONTH. THE COLDEST LOW TEMPERATURE
OF THE MONTH WAS 30 DEGREES ON THE 3RD...WHICH ALSO MARKED THE LAST
SUB-FREEZING TEMPERATURE OF THE SPRING. TEMPERATURES MODERATED INTO
THE SECOND WEEK OF THE MONTH...AND A SHARP WARM-UP ARRIVED ON THE
13TH AND 14TH...WITH HIGHS OF 90 AND 102 DEGREES...RESPECTIVELY. THE
102 ON THE 14TH NOT ONLY SET A DAILY RECORD...BUT WAS ALSO THE
EARLIEST-EVER OCCURRENCE OF 100+ DEGREES...SMASHING THE
PREVIOUS-EARLIEST SET ON MAY 20, 1925. ALTHOUGH A COLD FRONT EASED
HIGH TEMPERATURES BACK DOWN INTO THE 80S FROM THE 15TH-18TH...THE
SEVEN-DAY STRETCH FROM THE 13TH-19TH WAS CLEARLY THE WARMEST PART OF
THE MONTH. FOLLOWING THE ROLLER-COASTER RIDE IN TEMPERATURES DURING
THE FIRST HALF OF THE MONTH...THE LATTER HALF ACTUALLY AVERAGED
FAIRLY CLOSE TO NORMAL ON MOST DAYS. THE MILDEST LOW TEMPERATURE OF
THE MONTH WAS 66 DEGREES ON THE 26TH.

AS FOR SEVERE THUNDERSTORMS...THE CITY OF GRAND ISLAND MANAGED TO
DODGE THE VAST MAJORITY OF HAIL AND DAMAGING WIND EVENTS THAT
AFFECTED MUCH OF SOUTH CENTRAL NEBRASKA DURING WHAT WAS AN ACTIVE
THUNDERSTORM MONTH. HOWEVER...NICKEL SIZE HAIL WAS REPORTED IN THE
CITY ON THE AFTERNOON OF THE 19TH...WITH QUARTER SIZE HAIL REPORTED
JUST TO THE SOUTHWEST IN THE ALDA AREA. THE HIGHEST WIND GUST OF THE
MONTH AT CENTRAL NEBRASKA REGIONAL AIRPORT WAS ONLY 45 MPH FROM THE
SOUTHEAST...AND OCCURRED AROUND SUNRISE ON MEMORIAL DAY THE 27TH IN
ASSOCIATION WITH NEARBY DEPARTING THUNDERSTORMS.


...SPRING 2013 SEASONAL RECAP COVERING MARCH-MAY...

FOR THE METEOROLOGICAL SPRING SEASON OF MARCH...APRIL AND MAY AS A
WHOLE...THE AVERAGE DAILY MEAN TEMPERATURE WAS 47.9 DEGREES...OR 2.5
DEGREES BELOW THE NORMAL OF 50.4 DEGREES. THIS TIED SPRING 2013 FOR
THE 32ND-COOLEST ON RECORD OUT OF 118 YEARS DATING BACK TO 1896. THE
MAJORITY OF THIS COOL SEASONAL AVERAGE STEMMED FROM MARCH AND APRIL.
COMPARED TO SPRING 2012 ONE YEAR AGO...THIS SPRING WAS A NOTABLE
11.1 DEGREES COOLER. THE HOTTEST HIGH TEMPERATURE THIS SPRING WAS
102 DEGREES ON MAY 14TH...AND THE COLDEST HIGH TEMPERATURE WAS 29
DEGREES ON MARCH 25TH. THE COLDEST LOW TEMPERATURE OF THE SEASON WAS
10 DEGREES ON MARCH 2ND...AND THE MILDEST LOW WAS 66 DEGREES ON MAY
26TH.

TURNING TO PRECIPITATION...THE SEASONAL TOTAL OF 12.24 INCHES WAS
3.50 INCHES ABOVE NORMAL...AND RANKED AS THE 17TH-WETTEST SPRING ON
RECORD OUT OF 118 YEARS. THIS WAS IN SHARP CONTRAST TO ONE YEAR
AGO...WHEN SPRING 2012 ONLY FEATURED 4.53 INCHES OF PRECIPITATION.
THE WETTEST CALENDAR DAY THIS SPRING WAS MAY 25TH WITH 2.82
INCHES...AND THE SNOWIEST CALENDAR DAY WAS APRIL 18TH WITH 4.0
INCHES. SNOWFALL DURING THE MARCH-MAY SPRING SEASON TOTALED 13.8
INCHES...WHICH WAS TWICE THE NORMAL AMOUNT OF 6.9 INCHES. THIS
INCLUDED THE 9TH-SNOWIEST APRIL ON RECORD...AND THE FIRST MEASURABLE
SNOW IN MAY SINCE 1967.

THE TOTAL SNOWFALL FOR THE 2012-2013 SEASON WAS 35.2 INCHES...WHICH
WAS 6.2 INCHES ABOVE THE NORMAL OF 29.0 INCHES. THIS RESULTED IN A
TIE FOR THE 32ND-SNOWIEST SEASON ON RECORD OUT OF 118 YEARS.
