A broken line of storms is moving northeastward across eastern Iowa towards northwest Illinois. With already soaked grounds and repeated rounds of storms possible, localized flash flooding is the primary threat with this line. Lightning and gusty winds remain possible as well. Remember to slow down when driving in reduced visibility and on wet pavement!
Additional rounds of rain with embedded storms will be seen through Saturday afternoon before ending from west to east. A few strong to severe storms are possible this evening south of I-80. Breezy conditions will be developing on Saturday as well.
Moderate to heavy rainfall will continue tonight into Saturday. An additional 0.5 to 2+ inches of rain are possible by mid-day Saturday. Rainfall rates may approach 1 inch per hour at times in storms tonight/Saturday which may result in flash flooding in urban or poor drainage areas.
