A drastic change in the weather is expected as Iowans flip their calendars to the month of October. National Weather Service meteorologist Brad Small says showers and storms will move from west to east across the state sometime after midnight. Some of the storms could be severe.
“Generally, the greatest threat will be in the form of large hail,” Small said. “There could be some damaging winds and possibly a tornado or two toward the Missouri border, but for the vast majority of the state the main threats will be large hail and heavy rain.” Some areas of the state could receive one to two inches of rain through Thursday and minor flooding could occur in places were rivers and streams are already running high. The rain and storms on Thursday will be followed by much cooler temperatures.
“Friday will be a very fall-like day, probably the most extreme we’ve seen so far this season,” Small said. “Highs will struggle to get into the low 50s, with off and on rain and some brisk winds too.” Partly to mostly cloudy conditions are expected statewide Saturday and Sunday with highs in the mid 50s to low 60s.
