FRONTAL BOUNDARY CONTINUES TO WEAKEN AS IT CROSSES IOWA. UPPER LEVEL FEATURES FAVORING THE FRONT TO CONTINUE TO STRETCH AND LOSE INTEGRITY AND LESSEN TSHOWER ACTIVITY ALONG THE BOUNDARY IN THE NEXT
24 HOURS. THE UPPER LEVEL SYSTEM WILL SWING EAST BY EARLY THURSDAY MORNING.......AND TAKE ANY CHANCES FOR ADDITIONAL SHOWERS ALONG WITH IT. TONIGHT...HOWEVER...WE STILL HAVE A JUICED AIRMASS - WITH RANFALL AMOUNTS OF 1.5 TO 2.00 INCH RANGE FROM MIDNITE TO EARLY THURSDAY.

BY LATE THURSDAY SOME PUSH OF DRIER AIR TO ADVANCE INTO CENTRAL IOWA - TEMPS WILL BE SLIGHTLY COOLER. WITH MORNING TEMPS IN THE 50S TO LOWER 60S, THE POTENTIAL EXISTS FOR SOME WIDESPREAD FOG FRIDAY AND SATURDAY MORNING.

****HEAT IS ON IT'S WAY - WE'RE LOOKING AT AN EXTENDED PERIOD (A WEEK) OF TEMPS IN THE LOW TO MID 90'S, DEW POINTS WELL INTO THE 70'S. AND HEAT INDEX'S IN THE 100-110 RANGE.....WE'LL SEE TYPICAL SUMMERTIME AFTERNOON TSHOWERS DURING THE PERIOD.......LOOK OUT WHEN THIS ONE BREAKS THOUGH....MAJOR STORM OUTBREAK WILL ACCOMPANY A COLD FRONTAL PASSAGE TO BREAK THE PATTERN.........
