Oct. 2012 Climate Summaries For Grand Island, Hastings, Kearney, Ord

 For the NWS Hastings coverage area, the big story during October continued to be the ongoing extreme to exceptional drought in most areas. However, there was a noticeable difference in monthly precipitation totals across the area from northwest to southeast...with most northwestern counties remaining extremely dry while parts of some southeastern counties actually observed above normal rainfall. Temperature-wise, the entire area recorded a monthly mean temperature generally 1-3 degrees below normal. For places such as Grand Island, this broke a streak of 12 consecutive months of above normal temperatures!

...OCTOBER 2012 NARRATIVE FOR CENTRAL NEBRASKA REGIONAL AIRPORT...

A CONTINUED LACK OF RAIN...BUT BELOW NORMAL TEMPS FOR A CHANGE...

FINALLY BREAKING A STREAK OF 12 CONSECUTIVE MONTHS OF ABOVE NORMAL
TEMPERATURES...OCTOBER ACTUALLY FEATURED A BELOW NORMAL MONTHLY
AVERAGE.
HOWEVER...THE SAME OLD DRY STORY CONTINUED IN THE
PRECIPITATION DEPARTMENT...AS GRAND ISLAND NOTCHED ITS EIGHTH
STRAIGHT MONTH OF BELOW NORMAL RAINFALL...KEEPING THE AREA MIRED IN
EXTREME TO EXCEPTIONAL DROUGHT ACCORDING TO THE U.S. DROUGHT
MONITOR.

FOCUSING FIRST ON TEMPERATURES...THE DAILY MEAN TEMPERATURE
RESULTING FROM AVERAGING BOTH THE HIGHS AND LOWS WAS 50.3
DEGREES...OR 1.9 DEGREES BELOW NORMAL. THE GREATEST CONTRIBUTING
FACTOR TO THE BELOW NORMAL MONTH WAS DAILY LOW TEMPERATURES WHICH
AVERAGED 37.2 DEGREES (2.4 BELOW NORMAL). DAILY HIGHS AVERAGED 63.4
DEGREES (1.4 BELOW NORMAL). THE WARMEST HIGH TEMPERATURE OF THE
MONTH WAS 86 DEGREES ON THE 3RD...AND THE COLDEST LOW OF 25 DEGREES
OCCURRED ON SEVERAL OCCASIONS...INCLUDING ON THE 6TH WHICH WAS THE
FIRST OFFICIAL HARD FREEZE OF THE FALL SEASON. BREAKING DOWN THE
MONTH INTO TEMPERATURE TRENDS...THERE WERE TWO FAIRLY DISTINCT
PERIODS OF WELL BELOW NORMAL READINGS...ONE FOCUSED BETWEEN THE
4TH-7TH AND THE OTHER BETWEEN THE 25TH-27TH. DURING THE FIRST OF
THESE STRETCHES...THE HIGH TEMPERATURE OF 45 DEGREES ON THE 6TH SET
A NEW RECORD-COOLEST MAXIMUM TEMPERATURE FOR THE DATE. ON THE WARMER
SIDE OF THINGS ONLY FOUR DAYS REACHED OR EXCEEDED 80 DEGREES DURING
THE MONTH...BUT THIS INCLUDED BACK-TO-BACK DAYS ON THE 15TH-16TH.
FOCUSING ON WEEK-LONG PERIODS...THE OVERALL COOLEST WEEK PER DAILY
HIGH TEMPERATURES WAS CENTERED BETWEEN THE 22ND-28TH...DURING WHICH
ONLY ONE DAY EXCEEDED 56 DEGREES.

PRECIPITATION-WISE...THE MONTHLY TOTAL OF 0.78 INCHES AT CENTRAL
NEBRASKA REGIONAL AIRPORT WAS ONLY 42 PERCENT OF THE NORMAL AMOUNT
OF 1.86 INCHES. HOWEVER...ONE ONLY HAS TO LOOK BACK TWO YEARS TO
FIND A DRIER OCTOBER...AS 2010 ONLY HAD 0.30 INCHES. THE MAJORITY OF
PRECIPITATION THIS MONTH FELL DURING THUNDERSTORMS ON THE 13TH WITH
0.48 INCHES. PROLONGING A DUBIOUS TREND THAT HAS LASTED SEVERAL
MONTHS NOW...GRAND ISLAND CONTINUED TO RECEIVE LESS RAINFALL THAN
NEARBY LOCATIONS SUCH AS HASTINGS AIRPORT...WHICH TALLIED 0.68
INCHES MORE THAN GRAND ISLAND DURING OCTOBER. EARLY-SEASON SNOWFALL
WAS HARDLY AN ISSUE AT ALL DURING THE MONTH...WITH ONLY A
NON-MEASURABLE TRACE FALLING ON THE 25TH. FOR THE YEAR 2012 AS A
WHOLE...THE TOTAL PRECIPITATION OF 9.36 INCHES IS A WHOPPING 15.50
INCHES BELOW NORMAL AND RANKS AS THE DRIEST FIRST 10 MONTHS OF ANY
YEAR ON RECORD OUT OF 117 YEARS...AHEAD OF THE PREVIOUS LOW MARK OF
10.22 INCHES IN 1934.

ALTHOUGH NO SEVERE THUNDERSTORMS AFFECTED GRAND ISLAND DURING THE
MONTH...A TWO-DAY HIGH WIND EVENT BUFFETED THE REGION BETWEEN THE
17TH-18TH AS A DEEP LOW PRESSURE SYSTEM FORMED IN MINNESOTA. PEAK
WIND GUSTS FROM THE NORTHWEST ON BOTH DAYS WERE 61 MPH AND 63
MPH...RESPECTIVELY.

FOCUSING FIRST ON TEMPERATURES...THE MONTHLY MEAN TEMPERATURE
RESULTING FROM AVERAGING THE HIGHS AND LOWS WAS 49.5 DEGREES (3.1

TEMPERATURE TRENDS...THERE WERE TWO FAIRLY DISTINCT PERIODS OF WELL
BELOW NORMAL READINGS...ONE FOCUSED BETWEEN THE 4TH-7TH AND THE
OTHER BETWEEN THE 25TH-27TH. DURING THE FIRST OF THESE
STRETCHES...THE HIGH TEMPERATURE OF 43 DEGREES ON THE 6TH SET A NEW
RECORD-COOLEST MAXIMUM TEMPERATURE FOR THE DATE...AND IN FACT WAS
THE COOLEST MAX TEMPERATURE EVER RECORDED IN HASTINGS DURING THE
FIRST SIX DAYS OF OCTOBER! ON THE WARMER SIDE OF THINGS ONLY TWO

INCHES...FELL DURING THUNDERSTORMS BETWEEN THE LATE EVENING OF THE
12TH AND THE EARLY MORNING HOURS OF THE 13TH. DESPITE THE STEADILY
GROWING RAINFALL DEFICIT OVER THE PAST SEVERAL MONTHS...HASTINGS
CONTINUES TO FAIR BETTER THAN NEARBY LOCATIONS SUCH AS GRAND ISLAND
CENTRAL NEBRASKA REGIONAL AIRPORT...WHICH MEASURED 0.68 INCHES LESS
THAN HASTINGS DURING OCTOBER. FOR THE YEAR 2012 AS A WHOLE...THE
HASTINGS TOTAL PRECIPITATION OF 18.12 INCHES STANDS 7.09 INCHES
BELOW NORMAL...AND MARKS THE DRIEST FIRST TEN MONTHS OF THE YEAR

A SEVERE LACK OF RAIN PERSISTS...AS TEMPS AVERAGE BELOW NORMAL

FOR THE SECOND CONSECUTIVE MONTH...THE MONTHLY MEAN TEMPERATURE
REGISTERED BELOW NORMAL...BUT THIS TIME AROUND WAS THE FARTHEST
BELOW NORMAL SINCE SEPTEMBER 2011. HOWEVER...THE SAME DIRE STORY
CONTINUED IN THE PRECIPITATION DEPARTMENT...AS ORD NOTCHED ITS SIXTH
STRAIGHT MONTH OF WELL BELOW NORMAL RAINFALL...KEEPING THE AREA
MIRED IN EXCEPTIONAL DROUGHT ACCORDING TO THE U.S. DROUGHT MONITOR.

FOCUSING FIRST ON TEMPERATURES...THE MONTHLY MEAN TEMPERATURE
RESULTING FROM AVERAGING BOTH THE HIGHS AND LOWS WAS 47.1
DEGREES...OR 2.5 DEGREES BELOW NORMAL. THE GREATEST CONTRIBUTING
FACTOR TO THE BELOW NORMAL MONTH WAS DAILY LOW TEMPERATURES WHICH
AVERAGED 31.6 DEGREES (4.7 BELOW NORMAL). DAILY HIGHS AVERAGED 62.5
DEGREES (0.5 BELOW NORMAL). THE WARMEST HIGH TEMPERATURE OF THE

ON THE 7TH. THE FIRST OFFICIAL HARD FREEZE OF THE FALL SEASON
OCCURRED ON THE 2ND WHEN THE MERCURY DROPPED TO 25 DEGREES. BREAKING

THIS MARKED THE 3RD-DRIEST OCTOBER OUT OF THE PAST 36 YEARS...AND
THE DRIEST SINCE 0.21 INCHES IN 1988. NEARLY ALL OF THE
PRECIPITATION FOR THE MONTH FELL DURING THE EARLY MORNING OF THE
25TH...AND CONSISTED OF A HEAVIER-THAN-EXPECTED SLUSHY SNOWFALL OF
2.5 INCHES. SINCE THE ONGOING DRY SPELL REALLY BECAME ESTABLISHED IN
JUNE...ORD HAS MEASURED AN ASTOUNDINGLY MEAGER 1.72 INCHES OF
PRECIPITATION DURING THE PAST FIVE MONTHS...WHICH IS ONLY 12
PERCENT OF THE NORMAL AMOUNT OF 14.32 INCHES! FOR THE YEAR 2012 SO
FAR...THE TOTAL PRECIPITATION OF 11.37 INCHES IS 11.96 INCHES BELOW
NORMAL...AND RANKS AS THE DRIEST FIRST 10 MONTHS OF ANY YEAR SINCE
AT LEAST 1977.

ALTHOUGH NO SEVERE THUNDERSTORMS AFFECTED ORD DURING OCTOBER...A
SIGNIFICANT TWO-DAY HIGH WIND EVENT BUFFETED THE REGION BETWEEN THE
