...JANUARY 2015 NARRATIVE FOR CENTRAL NEBRASKA REGIONAL AIRPORT...

ALTHOUGH THE MONTH AS A WHOLE AVERAGED A FEW DEGREES ABOVE NORMAL
AND PRECIPITATION FELL JUST SHORT OF NORMAL...THE THREE MOST
MEMORABLE/SIGNIFICANT WEATHER ASPECTS OF THE MONTH WERE:

1) A MAJOR TEMPERATURE TURN-AROUND: FOLLOWING 13 CONSECUTIVE DAYS OF
BELOW NORMAL COLD TO START THE MONTH...THINGS CHANGED IN A MAJOR WAY
AS THE FINAL 17 DAYS OF THE MONTH ALL FEATURED ABOVE NORMAL
TEMPS...INCLUDING A PARTICULARLY MILD 3-DAY STRETCH FROM THE 26TH-
28TH.

2) BONE-DRY UNTIL THE VERY LAST DAY: RIGHT UP UNTIL THE 31ST...GRAND
ISLAND WAS STARING AT THE 6TH-DRIEST JANUARY ON RECORD (OUT OF 120)
WITH A MEASLY TOTAL OF ONLY 0.03 INCHES. THEN AT THE "LAST MINUTE"
ON THE 31ST...A SIGNIFICANT STORM SYSTEM ENDED THE MONTH ON A RAINY
THEN SNOWY NOTE...WITH THE DAILY PRECIPITATION TOTAL OF 0.44 INCHES
BLOWING AWAY ANY NOTION OF GRAND ISLAND HAVING ONE OF THE DRIEST
MONTHS OF JANUARY ON RECORD.

3) A NEW HIGH PRESSURE RECORD: AN UNUSUALLY STRONG ARCTIC HIGH
PRESSURE SYSTEM PASSED OVER THE AREA ON THE 7TH...SETTING A RECORD
FOR THE HIGHEST ATMOSPHERIC SEA LEVEL PRESSURE EVER MEASURED AT
GRAND ISLAND...TOPPING OUT AT 1056.9 MILLIBARS (31.21 INCHES OF
MERCURY).

FOCUSING ON TEMPERATURES IN MORE DETAIL...THE OVERALL AVERAGE
MONTHLY TEMPERATURE (RESULTING FROM AVERAGING BOTH THE HIGHS AND
LOWS) WAS 27.6 DEGREES...WHICH WAS 2.5 DEGREES ABOVE NORMAL. THE
MAJORITY OF THE ABOVE NORMAL AVERAGE STEMMED FROM DAILY
HIGHS...WHICH AVERAGED 4.3 DEGREES ABOVE NORMAL. AS OUTLINED
ABOVE...IT WAS A UNIQUE MONTH WITH EACH OF THE FIRST 13 DAYS
AVERAGING BELOW NORMAL AND EACH OF THE LAST 17 DAYS ABOVE
NORMAL...WITH A SINGLE TRANSITION DAY IN BETWEEN (ON THE 14TH) THAT
EQUALED ITS DAILY AVERAGE. STARTING WITH THE EARLY-MONTH COLD
SNAP...COUNTING THE FINAL FIVE DAYS OF DECEMBER THIS ACTUALLY ENDED
UP BEING AN IMPRESSIVE 18-DAY STRETCH OF BELOW NORMAL TEMPERATURES.
MORE SPECIFICALLY...THE AVERAGE DAILY TEMPERATURE FROM DEC. 27-JAN.
14 WAS ONLY 13.2 DEGREES...MARKING THE COLDEST STRETCH OF WEATHER
BETWEEN THOSE PARTICULAR DATES IN 27 YEARS. DURING THIS FIRST PART
OF JANUARY...THE OVERALL-COLDEST WEEK WAS CENTERED FROM THE 3RD-
9TH...DURING WHICH HIGH TEMPERATURES ON FIVE OF THE SEVEN DAYS
FAILED TO EXCEED 26 DEGREES. THIS INCLUDED THE OVERALL-COLDEST DAY
OF THE MONTH ON THE 4TH...WITH A HIGH OF ONLY 9 AND A LOW OF -4.
ONCE THE TEMPERATURE PATTERN CHANGED...IT DID SO IN A MAJOR WAY AS
10 OF THE LAST 17 DAYS REACHED AT LEAST 50 DEGREES...AND A
REMARKABLE THREE-DAY STRETCH FROM THE 26TH-28TH FEATURED HIGHS
BETWEEN 63-68 DEGREES...WITH THE HIGH OF 68 ON THE 28TH SETTING A
NEW DAILY RECORD. MORE IMPRESSIVELY...THE THREE-DAY AVERAGE HIGH
TEMPERATURE OF 65.0 DEGREES MARKED THE THIRD-WARMEST THREE-DAY
STRETCH OF JANUARY HIGH TEMPERATURES ON RECORD...AND THE WARMEST
SINCE A 65.3 AVERAGE FROM JAN. 11-13, 1987 (28 YEARS AGO). THE MOST
EXTREME DAY-TO-DAY CHANGE IN HIGH TEMPERATURES DURING THE MONTH WAS
A 27-DEGREE WARM-UP FROM 12 DEGREES ON THE 7TH TO 39 DEGREES ON THE
8TH.

TURNING TO JANUARY PRECIPITATION...THE TOTAL OF 0.47 INCHES AT
CENTRAL NEBRASKA REGIONAL AIRPORT FELL ONLY 0.06 INCHES SHY OF THE
30-YEAR NORMAL OF 0.53 INCHES...AND ACTUALLY MARKED THE WETTEST
JANUARY SINCE 2011 (1.49 INCHES). AS OUTLINED ABOVE...THE VAST
MAJORITY OF MONTHLY PRECIPITATION FELL ON THE VERY LAST DAY AS RAIN
TRANSITIONED TO 2.8 INCHES OF SNOW...EQUATING TO 0.44 INCHES OF
TOTAL DAILY PRECIPITATION (NOTE: COUNTING THE PRECIPITATION THAT
CONTINUED INTO FEB. 1ST THE STORM-TOTAL PRECIPITATION WAS 0.59
INCHES AND 4.7 INCHES OF SNOW). PRIOR TO THE 31ST...THE ONLY
MEASURABLE LIQUID-EQUIVALENT OF THE MONTH WAS A MEASLY 0.03 INCHES
ON THE 3RD. AS FOR SNOWFALL...THE MONTHLY TOTAL OF 3.7 INCHES FELL
2.8 INCHES SHORT OF THE 30-YEAR NORMAL OF 6.5 INCHES. THROUGH THE
END OF JANUARY...TOTAL SNOWFALL FOR THE 2014-15 SEASON STOOD AT 11.8
INCHES...WHICH WAS 4.0 INCHES BELOW THE 30-YEAR NORMAL.

NO THUNDERSTORMS AFFECTED GRAND ISLAND DURING THE MONTH. AS FOR DAY-
TO-DAY WIND...ALTHOUGH THERE WAS PLENTY OF TYPICAL JANUARY BREEZE IT
WAS NOT AN OVERLY-WINDY MONTH. IN STARK CONTRAST TO LAST YEAR THERE
WERE NO SEVERELY-WINDY DAYS. ONLY THREE DAYS FEATURED PEAK
NORTHWESTERLY WIND GUSTS OF 50+ MPH...LED BY A 52 MPH PEAK GUST
SHORTLY AFTER MIDNIGHT ON THE 29TH. IN TOTAL...EIGHT DAYS FEATURED
PEAK NORTHWESTERLY GUSTS OF AT LEAST 40 MPH.
