WEATHER SUMMARY FOR IOWA
NATIONAL WEATHER SERVICE DES MOINES IA
901 PM CDT MON MAY 9 2005

SKIES WERE MOSTLY CLOUDY OVER THE NORTHERN HALF OF THE STATE THIS 
EVENING...WHILE THE SOUTHERN HALF OF THE STATE WAS MAINLY MOSTLY 
CLEAR. HIGH TEMPERATURES TODAY WERE IN THE MID 60S NORTHWEST TO THE 
UPPER 70S SOUTHEAST. EXTREMES RANGED FROM 63 AT ESTHERVILLE TO 79 AT 
CLINTON. BY 900 PM...READINGS HAD COOLED INTO THE 60S AND LOWER 70S. 
BREEZY SOUTHWEST TO WEST WINDS HAD DIMINISHED TO 5 TO 15 MPH.

LOW PRESSURE OVER CENTRAL MINNESOTA HAD PULLED A WEAK COLD FRONT 
THROUGH IOWA DURING THE AFTERNOON. THE RESULT WAS A PARTLY SUNNY SKY 
AND A WIND SHIFT TO WESTERLY AT 15 TO 25 MPH. TEMPERATURES BY 5 PM 
RANGED FROM THE MID TO UPPER 60S NORTH TO THE MID 70S SOUTH.

UNSETTLED WEATHER WILL BE THE RULE FOR THE REMAINDER OF THE WEEK.  
ANOTHER LOW PRESSURE SYSTEM WILL DEVELOP OVER THE SOUTHERN PLAINS 
AND LIFT NORTHEAST OVER NEBRASKA AND SOUTH DAKOTA. THE LOW WILL DRAG 
A WARM FRONT ACROSS THE UPPER MIDWEST. THIS FRONT WILL BE THE FOCUS 
FOR THUNDERSTORM DEVELOPMENT BEGINNING LATE TUESDAY. SEVERE WEATHER 
IS LIKELY IN THE VICINITY OF THE FRONT AS GULF MOISTURE MAKES THE 
AIR VERY UNSTABLE. THUNDERSTORMS WILL PRODUCE HEAVY RAIN TUESDAY 
NIGHT WITH MANY LOCATIONS RECEIVING SEVERAL INCHES OF RAIN.  

THE FRONT WILL STALL SOMEWHERE OVER THE REGION AND THOSE LOCATIONS 
ALONG AND AHEAD OF THE FRONTAL BOUNDARY WILL BE PRONE TO SEVERE 
WEATHER AND VERY HEAVY RAINFALL THROUGH FRIDAY. AT THIS TIME IT IS 
HARD TO TELL WHERE THE FRONT WILL BE BUT IT IS SAFE TO ASSUME THAT 
MOST LOCATIONS...ESPECIALLY ACROSS IOWA...WILL RECEIVE A PERIOD OF 
HEAVY RAIN.  LOCALIZED FLASH FLOODING MAY ALSO OCCUR.
