THE LOW CLOUDS AND FOG FROM THE MORNING GAVE WAY TO A PARTLY TO
MOSTLY SUNNY SKY.  THE CLOUDS THAT ARE PRESENT DEVELOPED MAINLY OVER
THE AREAS THAT SAW THE FOG THIS MORNING.  A SOUTH WIND AT 10 TO 20
MPH AND THE SUNSHINE HELPED TO PUSH TEMPERATURES INTO THE MID TO
UPPER 60S ACROSS THE STATE.  BY EARLY AFTERNOON...A FEW READINGS
WERE STILL IN THE LOWER 60S ACROSS THE FAR EAST WITH A FEW 70S BEING
REACHED ACROSS THE FAR  WEST.

TODAY WILL BE DRY AND WARM BUT WE ARE TRANSITIONING TO A VERY ACTIVE
SPRING PATTERN AND BY TONIGHT THUNDERSTORM CHANCES WILL INCREASE
ACROSS THE FAR WEST AS WARMER AND MORE MOIST AIR WORKS INTO THE
REGION.  A STORM SYSTEM OVER THE HIGH PLAINS WILL INTENSIFY AND
DEVELOP A WARM FRONT WHICH WILL STRETCH ACROSS NORTHERN IOWA
TONIGHT.  ON SUNDAY THIS LOW WILL MOVE INTO THE CENTRAL PLAINS AS
THE WARM FRONT LIFTS INTO SOUTHERN MINNESOTA.  BY LATE AFTERNOON
THROUGH MONDAY MORNING THE LOW WILL SLOWLY SHIFT EAST ACROSS
NORTHERN IOWA AND SOUTHERN MINNESOTA.  THUNDERSTORMS WILL LIKELY BE
ONGOING BY SUNDAY MORNING ACROSS THE EASTERN DAKOTAS AND NEBRASKA
THEN SLOWLY SHIFT EASTWARD.  THEY WILL WORK INTO WESTERN IOWA BY
LATE AFTERNOON AND INTENSIFY AS THEY DO SO.  STORMS DURING THE LATE
AFTERNOON AND EVENING MAY BECOME SEVERE ACROSS THE WESTERN HALF OF
IOWA WITH LARGE HAIL AND DAMAGING WIND THE MAIN THREAT BUT INITIALLY
ISOLATED TORNADOES ARE ALSO POSSIBLE.

AFTER A BRIEF BREAK ON MONDAY...ANOTHER STRONG LOW PRESSURE SYSTEM
WILL MOVE ACROSS THE PLAINS TUESDAY.  THIS SYSTEM WILL BE FURTHER
SOUTH AND THE WARM FRONT WITH THIS SYSTEM WILL LIE ACROSS NORTHERN
MISSOURI OR SOUTHERN IOWA WITH THE LOW SHIFTING NORTHEAST THROUGH
THURSDAY.  STRONG TO SEVERE STORMS ARE EXPECTED OVER PARTS OF
MISSOURI AND KANSAS TUESDAY AND POSSIBLY AS FAR NORTH AS SOUTHERN
IOWA.  ON WEDNESDAY EASTERN IOWA AND PORTIONS OF WESTERN ILLINOIS
WILL SEE STRONG STORMS AS THAT SYSTEM SHIFTS EAST.  AFTER ANOTHER
BRIEF BREAK...A THIRD SYSTEM WILL IMPACT THE SAME AREA AGAIN NEXT
WEEKEND.

HIGHS ON SUNDAY WILL SURGE INTO THE UPPER 70S TO LOWER 80S.  ON
MONDAY HIGHS ACROSS NORTHWEST IOWA AND LOCATIONS WEST AND NORTH WILL
BE IN THE 60S...WITH 80S ACROSS SOUTHEAST IOWA AND LOCATIONS EAST
AND SOUTH.  HIGHS THE REST OF THE WEEK WILL BE IN THE 60S TO LOWER
