EARLY THIS MORNING, AN UPPER LEVEL WAVE IS IN THE PROCESS OF  
SLOWLY MOVING THROUGH THE AREA, WITH THE CENTER OF THE 500MB LOW  
SITUATED ALMOST DIRECTLY OVER CENTRAL NEBRASKA. THE AREA REMAINED  
MOSTLY DRY THROUGH THE EVENING, ALTHOUGH SHORT-TERM MODELS  
INDICATE THAT ADDITIONAL RAIN WILL DEVELOP INTO THE PRE-DAWN HOURS  
OF WEDNESDAY, BEFORE GRADUALLY SHIFTING SOUTHEASTWARD WITH THE  
UPPER-LEVEL SYSTEM.  
 
THE AREA WILL DRY OUT FROM NORTH TO SOUTH TODAY. IF CURRENT  
TRENDS HOLD, PRECIPITATION SHOULD END BY AROUND DAWN IN  
NORTHWESTERN PARTS OF THE AREA (LEXINGTON, ORD, ETC), MID MORNING  
IN THE TRI-CITIES, AND BY MID AFTERNOON IN SOUTHEASTERN PARTS OF  
THE FORECAST AREA (BELOIT, HEBRON, ETC). WE SHOULD SEE RAPID  
CLEARING SKIES BEHIND THE PRECIPITATION ALLOWING SOME LOCATIONS TO  
SALVAGE A PRETTY NICE AFTERNOON AS HIGHS REACH THE MID 50S TO LOW  
60S. WINDS WILL ALSO TAPER OFF THIS AFTERNOON AS THE SURFACE  
RIDGE MOVES OVERHEAD AND THE PRESSURE GRADIENT WEAKENS.  
 
LIGHT WINDS AND CLEAR SKIES SHOULD ALLOW TEMPERATURES TO FALL  
INTO THE 30S ACROSS THE AREA TONIGHT.  
 
ATTENTION THEN SHIFTS TO THE NEXT WAVE AND ASSOCIATED COLD FRONT  
THAT IS POISED TO MOVE THROUGH THE AREA THURSDAY MORNING. THIS  
WILL LIKELY BRING STRONGER NORTHERLY WINDS THAN THE LAST SYSTEM  
DID. GUSTS AROUND 35 MPH ARE LIKELY. DUE TO THE QUICK-MOVING  
NATURE OF THIS SYSTEM, IT WON'T HAVE MUCH MOISTURE TO WORK WITH,  
SO IT ONLY BRINGS A SLIGHT CHANCE OF VERY LIGHT RAIN...PROBABLY NO  
MORE THAN SPRINKLES AT MOST PLACES.  
 
HIGH PRESSURE ONCE AGAIN MOVES INTO THE AREA THURSDAY EVENING,  
ALLOWING SKIES TO CLEAR AND WINDS TO GO CALM. THIS WILL LIKELY  
LEAD TO A CHILLY OVERNIGHT WITH LOWS IN THE LOW-MID 30S.  
   
LONG TERM
 
(THURSDAY THROUGH TUESDAY)  
ISSUED AT 243 AM CDT WED APR 25 2018  
 
NO MAJOR CHANGES WERE MADE TO THE EXTENDED FORECAST. WE ARE STILL  
EXPECTING A SHIFT TO SIGNIFICANTLY WARMER WEATHER. THIS IS DUE TO  
UPPER RIDGE MOVING OVERHEAD ON FRIDAY-SATURDAY, AND EVENTUALLY  
SHIFTING INTO SOUTHWESTERLY FLOW SUNDAY THROUGH EARLY NEXT WEEK.  
 
HIGHS FRIDAY ARE EXPECTED TO BE IN THE UPPER 60S TO NEAR 70  
DEGREES...NOT OVERLY WARM, BUT IT WILL FEEL VERY NICE AS WINDS ARE  
EXPECTED TO BE LIGHT. SATURDAY WILL BE A BIT WARMER, BUT SOUTH  
WINDS WILL ALSO BE ON THE INCREASE DURING THE AFTERNOON. SOUTHERLY  
WINDS REALLY PICK UP SUNDAY THROUGH TUESDAY, ALLOWING  
TEMPERATURES TO REACH THE UPPER 70S AND LOW 80S.  
 
REGARDING PRECIPITATION, AN UPPER LOW IS EXPECTED TO MOVE ONTO  
THE WEST COAST LATE IN THE WEEK, AND WILL EJECT SEVERAL SMALLER  
WAVES INTO THE CENTRAL CONUS SUNDAY NIGHT THROUGH TUESDAY. WITH  
THE INCREASED WARM/MOIST AIR IN THE REGION, WE MAY FINALLY SEE  
SOME THUNDERSTORMS ACROSS THE LOCAL AREA AGAIN. DEPENDING ON HOW  
THINGS PLAY OUT, SEVERE WEATHER IS POSSIBLE, BUT FINE SCALE  
DETAILS ARE MUCH TOO UNCERTAIN TO PIN DOWN ANY SPECIFIC DETAILS.
