AFTER MONDAY BROUGHT SOME VERY MILD AIR TO THE REGION, TUESDAY WILL  
BE A MUCH, MUCH DIFFERENT DAY IN TERMS OF WEATHER. TEMPERATURES MONDAY  
AFTERNOON TOPPED OUT IN THE MID 50S TO LOW 60S ACROSS MUCH OF IOWA.  
THESE TEMPERATURES REMAINED WARM OVERNIGHT AS 4 AM TEMPERATURES ALONG  
AND SOUTH OF INTERSTATE 80 WERE IN THE UPPER 30S TO LOW 40S. NORMAL  
LOWS FOR THIS TIME OF YEAR ARE IN THE MID 20S, PLACING THE ACTUAL LOW  
TEMPERATURES FOR THIS TIME OF YEAR A SOLID 10 TO 15 DEGREES ABOVE  
NORMAL. ACROSS NORTHERN IOWA, HOWEVER, A COLD FRONT HAD BEGUN TO MAKE  
ITS WAY SOUTHEASTWARD INTO THE STATE. BEHIND THIS FRONT, TEMPERATURES  
WERE ALREADY IN THE MID TO UPPER 20S. WINDS WERE ALSO STARTING TO  
PICK UP BEHIND THE FRONT, AS SPEEDS WERE REACHING 10 TO 20 MPH, WITH  
GUSTS TO 25 MPH.

MORE THAN A FEW DEGREES, AS THEY MAY EVEN DROP A DEGREE OR TWO

WE SHOULD STAY COOL AGAIN WEDNESDAY, BUT WARM UP THURSDAY, AND  
ESPECIALLY FRIDAY. HIGHS THURSDAY WILL BE NEAR 50 DEGREES, AND HIGHS
