WEATHER SUMMARY FOR IOWA
NATIONAL WEATHER SERVICE DES MOINES IA
505 AM CDT FRI AUG 29 2014

SCATTERED SHOWERS AND THUNDERSTORMS WITH HEAVY RAINFALL DEVELOPED
ALONG THE I-80 CORRIDOR DURING LAST EVENING AND PUSHED TO THE
NORTHEAST OVERNIGHT REACHING FAR NORTH CENTRAL IOWA BY 5 AM.  MANY
LOCATIONS THAT SAW THUNDERSTORMS OVERNIGHT ALSO SAW ANYWHERE FROM AN
INCH AND A HALF TO 3 INCHES OF ADDITIONAL RAINFALL.  BY 5 AM
TEMPERATURES ACROSS IOWA WERE IN THE MID TO UPPER 60S AND THE WIND
WAS LIGHT OUT OF THE SOUTH.

ANOTHER STORMY DAY IS ON TAP FOR MUCH OF THE REGION AS YET ANOTHER
UPPER LEVEL DISTURBANCE MOVES ACROSS THE UPPER MIDWEST FOLLOWED BY
AN UPPER LEVEL TROUGH.  AT THE SURFACE A COLD FRONT WILL SWEEP THE
REGION THROUGH THIS EVENING.  DURING PEAK HEATING AND LASTING INTO
THE EVENING HOURS STORMS WILL RE-DEVELOP ALONG AND AHEAD OF THE
FRONT.  HEAVY RAINFALL WILL ONCE AGAIN BE LIKELY WITH THE STORMS AND
WITH SOME SUN TODAY...THE AIRMASS WILL BECOME UNSTABLE ENOUGH TO
ALLOW SOME STORMS TO BECOME VERY STRONG TO SEVERE.  AN ISOLATED
STORM COULD PRODUCE LARGE HAIL OR DAMAGING WIND.

AFTER THE FRONT PASSES WE WILL SEE A BRIEF RETURN TO DRY CONDITIONS
AND SEASONALLY WARM TEMPERATURES.  HOWEVER...BY LATE SUNDAY THROUGH
MONDAY YET ANOTHER STORM SYSTEM WILL PASS ACROSS THE UPPER MIDWEST.
THIS SYSTEM IS FAIRLY POTENT AND WILL BRING THE BEST CHANCE FOR
SEVERE STORMS THAT WE HAVE SEEN FOR SOME TIME.  IN ADDITION TO AN
INCREASED THREAT FOR SEVERE WEATHER...HEAVY RAINFALL WILL ALSO BE
LIKELY.  AFTER THAT SYSTEM PASSES ON TUESDAY THE REGION WILL FINALLY
GET A CHANCE TO DRY OUT INTO THE MIDDLE OF NEXT WEEK.  HIGHS THROUGH
THE MIDDLE OF NEXT WEEK WILL BE IN THE UPPER 70S TO MID 80S WITH
LOWS IN THE 60S.
