HIGH PRESSURE WILL BE IN PLACE THRU THE NEXT 7 DAYS RESULTING IN WARMER THAN NORMAL TEMPS AFTER MID WEEK. HIGH PRESSURE WILL MOVE EAST, RESULTING IN AN INCREASE IN SOUTHERLY FLOW - TAKING TEMPS FROM THE LOW 60'S TODAY, WELL INTO THE 70'S BY LATE WEEK.......
DON'T GET USED TO THIS WEATHER HOLDING OUT....JUST AS STRONG HIGH PRESSURE BUILDS OVER THE MIDWEST, LOW PRESSURE HAS BUILT OVER THE COAST FORMING A BLOCKING SITUATION HOLDING THE HIGH BACK FROM MOVING EAST. BY THE END OF NEXT WEEKEND, THE HIGH WILL WEAKEN AND MOVE EASTWARD......BY LATE NEXT WEEK, IOWA WILL RIGHT BACK INTO FALL - AND IT WILL BE THE FALL THAT IOWA IS KNOWN FOR.
