AN UPPER LEVEL DISTURBANCE OVER EASTERN IOWA IS INTERACTING
WITH AN UNSTABLE ATMOSPHERE LEADING TO THE DEVELOPMENT OF

STORMS WILL POSS A SEVERE THREAT THROUGH EARLY THIS EVENING.
THE MAIN THREATS FROM THESE THUNDERSTORMS WILL BE WIND GUSTS IN
EXCESS OF 70 MPH AND HAIL TO THE SIZE OF QUARTERS.

PERIODS OF HEAVY RAINFALL WILL LIKELY ACCOMPANY THESE STORMS.
ADDITIONAL THUNDERSTORMS ARE EXPECTED TONIGHT AS A LOW LEVEL
JET STRENGTHENS...AND THESE STORMS COULD BE SLOW MOVING AND
CONTAIN VERY HEAVY RAINFALL. THEREFORE...THE POTENTIAL FOR
FLASH FLOODING DOES REMAIN A CONCERN...ESPECIALLY ACROSS AREAS
THAT HAVE RECEIVED HEAVY RAINFALL IN THE PAST 24 TO 48 HOURS.


.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.

THERE WILL BE PERIODIC CHANCES FOR THUNDERSTORMS WEDNESDAY
THROUGH FRIDAY. SOME OF THESE STORMS COULD BE SEVERE WEDNESDAY.
