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

THE MOST NOTEWORTHY CLIMATE/WEATHER ASPECT OF THE MONTH WAS A BIG
SWING IN TEMPERATURE TRENDS FROM THE FIRST HALF OF THE MONTH
(COOLER) TO THE SECOND HALF OF THE MONTH (WARMER). PRECIPITATION-
WISE...ALTHOUGH IT WAS NOT NEARLY AS WET AS AUGUST WAS...SEPTEMBER
AGAIN FEATURED ABOVE NORMAL RAINFALL...MARKING THE FIRST TIME IN
NEARLY ONE YEAR (SEP-OCT 2013) THAT CONSECUTIVE MONTHS WERE ABOVE
NORMAL.

STARTING WITH A CLOSER LOOK AT MONTHLY RAINFALL...THE TOTAL OF 3.03
INCHES AT CENTRAL NEBRASKA REGIONAL AIRPORT WAS 0.80 INCHES ABOVE
THE 30-YEAR SEPTEMBER NORMAL OF 2.23 INCHES. IN OTHER WORDS...GRAND
ISLAND RECEIVED 136 PERCENT OF NORMAL SEPTEMBER RAINFALL. ALTHOUGH
THIS ONLY RANKED AS THE 32ND-WETTEST SEPTEMBER ON RECORD OUT OF 119
YEARS DATING TO 1896...IT WAS THE WETTEST SEPTEMBER IN EIGHT
YEARS...SINCE 4.75 INCHES FELL IN 2006. THE MAJORITY OF RAIN FOR THE
MONTH (2.06 INCHES) FELL DURING THE FIRST HALF...HIGHLIGHTED BY 1.40
INCHES ON THE 9TH.

TEMPERATURE-WISE...ALTHOUGH THE MONTH AS A WHOLE WENT DOWN IN THE
BOOKS AS BEING VERY AVERAGE/TYPICAL...IT TRULY WAS A TALE OF A
COOLER FIRST HALF AND A WARMER SECOND HALF. STARTING WITH THE NET
RESULT...THE AVERAGE MONTHLY TEMPERATURE (RESULTING FROM AVERAGING
BOTH THE HIGHS AND LOWS) WAS 64.6 DEGREES...ONLY 0.5 DEGREES BELOW
THE 30-YEAR NORMAL. HOWEVER...BREAKING DOWN THE MONTH INTO ROUGHLY
HALVES...THE FIRST 16 DAYS AVERAGED NOTABLY COOL...AND IN FACT TIED
WITH 1974 FOR THE 2ND-COOLEST OPENING 16 DAYS OF SEPTEMBER ON RECORD
OUT OF 119 YEARS WITH AN AVERAGE TEMPERATURE OF ONLY 61.4 DEGREES.
THE ONLY SEPTEMBER ON RECORD THAT STARTED COOLER WAS 1993 (61.3
DEGREES). NEEDLESS TO SAY...A NOTABLE REVERSAL IN TEMPERATURE TRENDS
TOOK PLACE DURING THE LATTER HALF OF THE MONTH...AS THE 14-DAY
STRETCH FROM THE 17TH-30TH WAS THE 6TH-WARMEST ON RECORD WITH AN
AVERAGE TEMPERATURE OF 68.3 DEGREES...AND WAS THE WARMEST SINCE
1998. FOR THE MONTH AS A WHOLE...15 DAYS FEATURED AN ABOVE NORMAL
AVERAGE TEMPERATURE...14 DAYS WERE BELOW NORMAL AND ONE DAY EQUALED
ITS DAILY NORMAL. BREAKING DOWN THE MONTH INTO WEEK-LONG
CHUNKS...THE OVERALL-WARMEST WEEK CAME AT THE VERY END OF THE MONTH
FROM THE 24TH-30TH...AS SIX OF THE SEVEN DAYS FEATURED HIGHS OF AT
LEAST 82 DEGREES AND LOWS NEVER DROPPED BELOW 54 DEGREES.
HOWEVER...THE OUTRIGHT-WARMEST HIGH AND LOW TEMPERATURES OF THE
MONTH ACTUALLY OCCURRED EARLIER ON...CONSISTING OF A HIGH OF 90 ON
THE 19TH AND A LOW OF 66 ON THE 3RD. IN STARK CONTRAST...THE OVERALL-
COOLEST WEEK OF THE MONTH WAS CENTERED FROM THE 10TH-16TH...DURING
WHICH NO DAYS EXCEEDED 72 DEGREES AND LOWS EACH NIGHT WERE EITHER IN
THE 30S OR 40S. BY FAR THE CHILLIEST TWO DAYS DURING THIS STRETCH
WERE THE 11TH-12TH WITH HIGHS OF ONLY 52 AND 55
DEGREES...RESPECTIVELY. THE 52-DEGREE HIGH ON THE 11TH EVEN SET A
NEW RECORD FOR THE DATE. AS FOR LOW TEMPERATURES...THE LOW POINT OF
THE MONTH WAS 36 DEGREES ON THE 13TH...WHICH BROUGHT AN UNUSUALLY
EARLY ROUND OF PATCHY FROST TO PARTS OF THE AREA. IN FACT...THIS
TIED WITH THE SAME DATE IN 1949 FOR THE 8TH-EARLIEST 36-DEGREE-OR-
COLDER FALL TEMPERATURE ON RECORD...AND MARKED THE EARLIEST 36-
DEGREE-OR-COLDER TEMPERATURE IN GRAND ISLAND SINCE IT REACHED 36 ON
9-12-1975.

THE MOST EXTREME DAY-TO-DAY CHANGE IN HIGH TEMPERATURES DURING THE
MONTH WAS 17 DEGREES...CONSISTING OF A NOTICEABLE COOL-DOWN FROM 83
DEGREES ON THE 4TH TO 66 DEGREES ON THE 5TH.

ALTHOUGH GRAND ISLAND EXPERIENCED SEVERAL THUNDERSTORMS DURING THE
MONTH...NWS HASTINGS RECEIVED NO REPORTS OF LARGE HAIL OR DAMAGING
WINDS FROM ANYWHERE WITHIN HALL COUNTY DURING SEP. 2014. THE HIGHEST
WIND GUST OF THE MONTH AT THE AIRPORT WAS ONLY 41 MPH FROM THE NORTH-
NORTHWEST...AND OCCURRED ALONG A THUNDERSTORM OUTFLOW BOUNDARY ON
THE EVENING OF THE 1ST.
