MOST OF THE MONTH WAS DOMINATED BY A RIDGE IN THE WESTERN UNITED
STATES...WITH A TROUGH IN THE EAST. THIS RESULTED IN NORTHWEST 
FLOW ALOFT WHICH BROUGHT SEVERAL WEAK DISTURBANCES ACROSS THE 
AREA...HOWEVER THE ATMOSPHERE WAS FAIRLY DRY RESULTING IN THE 
SHORT WAVES ONLY PRODUCING CLOUDS AND LIGHT...IN 
ANY...PRECIPITATION. THERE WERE A COUPLE OF STRONGER SYSTEMS THAT 
MOVED NORTHEAST ACROSS THE AREA BRINGING A COUPLE OF DAYS OF 
MEASURABLE RAINFALL. ONE SLOW MOVING SYSTEM LATER IN THE 
MONTH...THE TWENTY FIFTH TO THE TWENTY SEVENTH...ALSO BROUGHT 
VERY STRONG WINDS...WITH PEAK WIND GUSTS AROUND 60 MPH ACROSS 
MUCH OF WESTERN AND NORTH CENTRAL NEBRASKA.  
 
DURING THE MONTH OF OCTOBER FOR NORTH PLATTE...THE AVERAGE DAILY 
HIGH TEMPERATURE WAS 68.5 DEGREES WHICH WAS 2.9 DEGREES ABOVE THE 
NORMAL OF 65.6 DEGREES. THE AVERAGE DAILY LOW TEMPERATURE WAS 
35.7 DEGREES WHICH WAS 2.0 DEGREES ABOVE THE NORMAL OF 33.7 
DEGREES. THE MEAN DAILY TEMPERATURE WAS 52.1 DEGREES WHICH WAS

FOR VALENTINE...THE AVERAGE DAILY HIGH TEMPERATURE WAS 68.6 
DEGREES WHICH WAS 5.1 DEGREES ABOVE THE NORMAL OF 63.5 DEGREES. 
THE AVERAGE DAILY LOW TEMPERATURE WAS 37.6 DEGREES WHICH WAS 4.5 
DEGREES ABOVE THE NORMAL OF 33.1 DEGREES. THE AVERAGE DAILY MEAN

PRECIPITATION RECORDS WERE SET DURING THE MONTH. UNLIKE NORTH 
PLATTE...VALENTINE DID SEE LIGHT SNOW DURING THE MONTH...ON 
OCTOBER 27...HOWEVER ONLY A TRACE WAS RECORDED. THIS IS WELL PAST 
THE 50 PERCENT CHANCE OF THE FIRST SNOW...WHICH IS OCTOBER 18.  
 
2010 WAS A BIG DIFFERENCE COMPARED TO LAST YEAR...2009...WHICH 
WAS THE SECOND COLDEST ON RECORD AND FOR NORTH PLATTE THE 
SNOWIEST MONTH ON RECORD. THE AVERAGE HIGH TEMPERATURE FOR 2009 
FOR NORTH PLATTE AND VALENTINE WERE ONLY 51.8 AND 49.8 DEGREES 
RESPECTFULLY...WHICH WAS LOWER THAN THE AVERAGE TEMPERATURE THIS 
YEAR. ALSO THERE WERE THREE STRONG LOW PRESSURE SYSTEMS THAT 
EFFECT THE AREA...WITH NORTH PLATTE RECORDING AN ALL TIME MONTHLY 
RECORD OF 30.3 INCHES OF SNOW.
