WELL ABOVE NORMAL TEMPERATURES CONTINUE TODAY WITH HIGHS IN THE  
UPPER 80S TO AROUND 90 IN SOME PLACES. SATELLITE CONTINUES TO SHOW A  
LITTLE BIT OF UPPER LEVEL HAZE FROM SMOKE FROM WILDFIRES IN THE  
WESTERN US. A BROAD SURFACE TROF IS CURRENTLY DRAPED ACROSS THE AREA  
AND SLOWLY WORKING ITS WAY EAST AND IS KEEPING OUR SURFACE WINDS  
RATHER LIGHT AND VARIABLE. AN UPPER LEVEL RIDGE AXIS IS NUDGING ITS  
WAY EAST AND HELPING TO KEEP SKIES MOSTLY CLEAR AND TEMPS WELL ABOVE  
NORMAL AS WE HEAD INTO THE START OF THE WEEKEND. EXPECTING WARMER  
LOWS TONIGHT, IN THE MID TO UPPER 50S, AHEAD OF A HOT DAY ON FRIDAY.  
WITH THE UPPER LEVEL RIDGE AXIS TILTED FAR EAST AND DRAPED ACROSS  
THE CENTRAL PLAINS FRIDAY, WE CAN EXPECT TO SEE ANOTHER HOT DAY!  
EXPECTING MOSTLY CLEAR SKIES AND HIGHS AROUND 90 FOR MOST OF SOUTH  
CENTRAL NEBRASKA, AND IN THE LOW TO MID 90S FOR NORTH CENTRAL  
KANSAS.  
 
A SURFACE COLD FRONT WILL DIVE SOUTH THROUGH THE PLAINS ON FRIDAY,  
BUT WILL ESSENTIALLY STALL OUT AND WEAKEN BY THE TIME IT REACHES US.  
THIS MEANS HIGHS ON SATURDAY WILL STILL BE WELL ABOVE NORMAL IN THE  
LOW TO MID 90S MOST PLACES. WESTERLY WINDS ON SATURDAY HAVE THE  
POTENTIAL TO PUSH HIGHS EVEN HIGHER FROM THE EFFECTS OF DOWNSLOPING  
AND DRYING SO I HAVE KEPT TEMPS ON THE WARM SIDE OF GUIDANCE TO  
ACCOUNT FOR THIS POSSIBILITY. REGARDING FIRE WEATHER POTENTIAL ON  
SATURDAY...WESTERLY WINDS WILL HELP BRING DEW POINTS DOWN AND  
DROP RHS INTO THE 20S AND TEENS IN A FEW PLACES. CURRENTLY WINDS  
LOOK TO STAY JUST BELOW 20 MPH BUT IT COULD BE CLOSE FOR A FEW  
PLACES. SO NEAR CRITICAL CONDITIONS ARE POSSIBLE MAINLY NORTH OF  
I-80 SATURDAY AFTERNOON.  
 
SATURDAY EVENING/NIGHT IS WHERE THINGS REALLY BEGIN TO CHANGE. AHEAD  
OF AN UPPER LEVEL TROF, A MORE POTENT SURFACE TROF IS EXPECTED TO  
DROP SOUTH THROUGH THE CENTRAL PLAINS AND BRING A SURGE OF COLDER  
AIR INTO THE REGION. THIS WILL PULL SUNDAY'S HIGHS BACK DOWN TO  
AROUND NORMAL, MAINLY IN THE LOW TO MID 70S. THE APPROACHING UPPER  
LEVEL TROF WILL SWING THROUGH THE PLAINS SUNDAY NIGHT INTO MONDAY  
MORNING AND COULD BRING SOME WEAK PRECIP CHANCES SUNDAY NIGHT. WITH  
NORTH AND NORTHWESTERLY FLOW ALOFT ON THE BACKSIDE OF THE TROF, AND  
NORTHERLY FLOW AT THE SURFACE, TEMPERATURES WILL TAKE ANOTHER TUMBLE  
INTO THE LOW TO MID 60S FOR THE MIDDLE OF THE WEEK. THIS SURGE OF  
COLDER AIR COULD ACTUALLY BRING OUR FIRST FROST POTENTIAL FOR THE  
YEAR WITH LIGHT WINDS AND LOWS EXPECTED TO BE IN THE MID TO UPPER  
30S EARLY THURSDAY MORNING.
