...BURWELL TORNADOES JUNE 16TH 2014...

ON MONDAY JUNE 16TH A STRONG STORM SYSTEM WAS TAKING SHAPE IN THE
PACIFIC NORTHWEST. WELL AHEAD OF THIS SYSTEM...A WARM AND HUMID
ATMOSPHERE WAS IN PLACE ACROSS MUCH OF CENTRAL AND EASTERN NEBRASKA
THANKS TO STRONG SOUTHERLY WINDS BRINGING MOISTURE ORIGINATING FROM
THE GULF OF MEXICO. BY MONDAY AFTERNOON...ONE PIECE OF THE STORM
SYSTEM OUT WEST WAS APPROACHING THE PLAINS FROM THE SOUTHWEST.
PLENTY OF SUNSHINE THROUGH THE AFTERNOON...COMBINED WITH THE
PLENTIFUL MOISTURE...ALLOWED A VERY UNSTABLE AIRMASS TO DEVELOP
ACROSS MUCH OF THE AREA. AS A BOUNDARY SEPARATING DRY AIR FURTHER
WEST FROM THE MORE MOIST AIR FURTHER EAST SURGED INTO NORTH CENTRAL
NEBRASKA...ISOLATED STRONG TO SEVERE THUNDERSTORMS DEVELOPED OVER
NORTHERN CUSTER AND SOUTHERN LOUP COUNTIES BY LATE AFTERNOON.

ONE OF THESE THUNDERSTORMS...A SPECIFIC TYPE OF THUNDERSTORM CALLED
A SUPERCELL...INTENSIFIED RAPIDLY AND MOVED ACROSS HIGHWAY 183
BETWEEN SARGENT AND TAYLOR AND PRODUCED A BRIEF TORNADO NORTH OF
SARGENT IN OPEN COUNTRY. THE STORM CONTINUED TO INTENSIFY AND MOVED
ALONG HIGHWAY 91 BETWEEN TAYLOR AND BURWELL...AND EVENTUALLY
PRODUCED SEVERAL TORNADOES AS IT APPROACHED AND MOVED PAST THE TOWN
OF BURWELL.

ONE OF THE TORNADOES...REPORTED AS A LARGE WEDGE TORNADO BY STORM
CHASERS...JUST MISSED THE TOWN OF BURWELL AND PRODUCED UP TO EF-2
DAMAGE FROM 1 MILE NORTH OF BURWELL TO 10 MILES EAST-NORTHEAST OF
THE TOWN. IN THIS AREA...TREE TRUNKS WERE SNAPPED...POWER POLES WERE
DESTROYED...AND A NUMBER OF OUTBUILDINGS DAMAGED OR DESTROYED AS
WELL. THANKFULLY NO INJURIES WERE REPORTED WITH ANY OF THE TORNADOES.

BY LATE EVENING...SIX SEPARATE TORNADO TOUCHDOWNS WERE REPORTED
ALONG A PATH 23 MILES LONG FROM NORTHEAST CUSTER COUNTY TO
SOUTHEASTERN GARFIELD COUNTY. THE EF-2 DAMAGE PRODUCED BY THE
STRONGEST TORNADOES CORRELATED TO WIND SPEEDS UP TO 130 MPH.


...LATE SEASON (MAY) THEN EARLY SEASON (SEPTEMBER) SNOW...

A STRONG LOW PRESSURE SYSTEM MOVED ACROSS THE AREA DURING THE SECOND
WEEK OF MAY.  SNOW IN MAY DOES HAPPEN ACROSS WESTERN AND NORTH
CENTRAL NEBRASKA...HOWEVER IT IS RARE TO OCCUR AFTER THE FIRST WEEK
OF THE MONTH.  THE LAST TIME WIDESPREAD SNOW WAS OBSERVED WAS IN
2008 BUT THIS WAS ON THE SECOND OF THE MONTH.  THIS YEAR...SNOW WAS
REPORTED ON THE 12TH OF MAY.

FOUR MONTHS LATER...IN SEPTEMBER...A RARE STRONG COLD FRONT BROUGHT
ARCTIC AIR TO THE REGION.  DURING THE EVENING HOURS OF THE 12TH AS
THE PRECIPITATION WAS ENDING A BRIEF CHANGEOVER TO SNOW OCCURRED
ACROSS THE SOUTHERN SANDHILLS AND PORTIONS OF SOUTHWEST NEBRASKA.
NOT ALL AREAS RECORDED SNOW...HOWEVER THOSE THAT DID...RECORDED THE
EARLIER SNOWFALL ON RECORD. THIS BROKE THE PREVIOUS EARLIEST
SNOWFALL OF SEPTEMBER 12...WHICH WAS SET IN 1989.


...ANOMALOUSLY COLD TEMPERATURES HIT NEBRASKA MID NOVEMBER...

NOVEMBER 2014 ACROSS NEBRASKA WAS COLDER THAN NORMAL THANKS TO A
STRONG COLD SNAP THAT IMPACTED THE AREA FROM THE 10TH THROUGH THE
17TH. AFTER TEMPERATURES IN THE 60S AND 70S THE FIRST WEEK OF THE
MONTH...A STRONG ARCTIC COLD FRONT MOVED ACROSS THE STATE DROPPING
TEMPERATURES SIGNIFICANTLY. THIS AIRMASS REMAINED IN PLACE FOR MORE
THAN A WEEK...WHICH LED TO MOST OF WESTERN AND NORTH CENTRAL
NEBRASKA OBSERVING TEMPERATURES THAT FAILED TO RISE ABOVE FREEZING
FOR 7 CONSECUTIVE DAYS. HIGHS THROUGH THIS PERIOD WERE GENERALLY IN
THE 20S...WHILE LOWS DROPPED INTO THE SINGLE DIGITS ABOVE ZERO TO
LOW TEENS BELOW ZERO. NORMAL HIGHS AND LOWS FOR THIS PERIOD WERE
AROUND 50 AND THE LOW 20S RESPECTIVELY. THERE WERE INSTANCES WHERE
DAILY HIGHS WERE COLDER THAN THE NORMAL LOW TEMPERATURE. COOLER THAN
NORMAL TEMPERATURES PERSISTED THROUGH THE 21ST OF THE MONTH.

AT VALENTINE...THREE RECORD LOW TEMPERATURES WERE BROKEN DURING THIS
COLD SNAP. THESE RECORD LOWS WERE THE FOLLOWING:

-13 DEGREES F / NOVEMBER 15TH / OLD RECORD: -10/1997
-13 DEGREES F / NOVEMBER 16TH / OLD RECORD: -12/1955
-14 DEGREES F / NOVEMBER 18TH / OLD RECORD:   0/1969

BECAUSE OF THE PERSISTENT COLD TEMPERATURES...ABUNDANT ICE WAS ABLE
TO FORM ON AREA RIVERS WHICH IN TURN CAUSED ICE JAMS TO DEVELOP IN
SOME LOCATIONS. THE ICE JAMMING WAS MOST NOTABLE ALONG THE NORTH
PLATTE RIVER NEAR LEWELLEN...THE SOUTH PLATTE RIVER AT NORTH
PLATTE...AND THE NORTH LOUP RIVER NEAR TAYLOR. THESE ICE JAMS CAUSED
HIGH RIVER LEVELS...BUT ONLY MINOR LOW LAND FLOODING WAS OBSERVED.
