..SEVERAL ABOVE NORMAL TEMPERATURE DAYS AHEAD
 
 
COLD FRONT MOVING THROUGH THE FORECAST AREA THIS AFTERNOON, WHICH  
ALLOWED HIGHS TO CLIMB INTO THE MID TO UPPER 70S AHEAD OF IT. THIS  
SET A NEW RECORD TEMPERATURE OF 75 AT LINCOLN, PREVIOUSLY RECORD  
WAS 72 SET IN 2011. OMAHA REACHED 72, BUT WAS JUST SHY OF THE  
RECORD OF 73 ALSO SET IN 2011. WINDS ALSO GUSTED TO ABOUT 43 TO 46  
MPH IMMEDIATELY BEHIND THE FRONT FOR ABOUT AN HOUR. WINDS WILL  
DIMINISH THIS EVENING AS HIGH PRESSURE CONTINUES TO BUILD INTO THE  
AREA.  
 
WEST NORTHWEST WINDS PREVAIL ON SATURDAY, BUT WILL BE SIGNIFICANTLY  
LOWER THAN TODAY. AND WHILE IT WILL BE COOLER ON SATURDAY WITH  
HIGHS IN THE MID TO UPPER 50S, IT WILL STILL BE WELL ABOVE NORMAL  
WHICH ARE IN THE MID 40S.  
 
LIGHT WEST SOUTHWEST FLOW CONTINUES ON SUNDAY, WHICH HELPS BOOST  
HIGHS INTO THE UPPER 50S TO LOWER 60S.  
 
WELL ABOVE NORMAL HIGHS ARE FORECAST MONDAY, WITH H85 TEMPS  
WARMING INTO THE UPPER TEENS. THIS SHOULD TRANSLATE INTO SURFACE  
HIGHS IN THE UPPER 60S TO LOWER 70S FOR US, WHICH WOULD BE ANOTHER  
RECORD BREAKING TEMPERATURE DAY AT OMAHA AND LINCOLN, WHERE  
RECORDS ARE 67 AND 68 RESPECTIVELY, BUT PROBABLY NOT WARM ENOUGH  
TO REACH 73 AT NORFOLK.

(MONDAY NIGHT THROUGH FRIDAY)

A STRONG COLD FRONT MOVES INTO THE AREA MONDAY NIGHT. THIS USHERS  
IN COOLER TEMPERATURES AND BREEZY CONDITIONS FOR TUESDAY, BUT  
HIGHS WILL STILL BE ABOVE NORMAL IN THE 50S.  
 
MODELS ARE FOCUSING ON A TROUGH MOVING THROUGH THE CENTRAL ROCKIES  
TUESDAY THEN ONTO THE PLAINS TUESDAY NIGHT. THE GFS IS TAKING A  
SLIGHTLY MORE SOUTHERN LATITUDINAL POSITION THAN THE ECMWF OR THE  
CANADIAN. GFS WOULD KEEP PRECIP SOUTH OF I80, BUT OTHER TWO MODELS  
SUGGEST IT COULD BE A LITTLE FURTHER NORTH. THUS, WILL HAVE A  
CHANCE OF RAIN AND SNOW FOR WEDNESDAY, BUT CONFIDENCE IS LOW  
RIGHT NOW DUE TO MODEL SPREAD. EVEN STILL, TEMPS ON WEDNESDAY ARE  
STILL ABOVE NORMAL, IN THE UPPER 40S TO LOWER 50S.  
 
DRY WEATHER CONTINUES NEXT THURSDAY AND FRIDAY AS ANOTHER WEAK  
REINFORCING COOL FRONT SETTLES INTO THE AREA, BUT WITH STILL JUST  
SLIGHTLY ABOVE NORMAL TEMPS IN THE MID TO UPPER 40S.
