The entire state is under the threat for severe thunderstorms later today (Wednesday). National Weather Service Meteorologist Cory Martin says the system is expected to enter western Iowa late this afternoon and push east through the evening and into the early overnight hours. “All modes of severe weather are possible including large hail, strong wind gusts, and also the possibility of a few tornadoes,” Martin said.
The biggest tornado threat appears to be over west-central and southwest Iowa, according to Martin. Heavy rain is also likely. “It remains to be seen if it’s going to lead to any flash flooding concerns. It looks like the storms will be moving at a decent clip. That would alleviate any threat for flash flooding, but it’s something that we’ll monitor,” Martin said.

ANAMOSA, Iowa (AP) – The National Weather has confirmed that a tornado destroyed and damaged buildings in a rural part of eastern Iowa’s Jones County.
The service rated Saturday night’s twister at EF1 with winds estimated at 100 mph. The twister touched down about 4 miles northeast of Anamosa and ran 3 miles east. It flattened or damaged farm buildings at two locations before lifting. No injuries were reported.
The first corn seeds got into the ground last week, but weather has kept most farmers out of the fields. The U-S-D-A’s week crop report says there were just three days suitable for fieldwork last week thanks to wet weather. Soil temperatures that are warm enough for planting have also been an issue. But there were some farmers who pulled the planter into the field — and two percent of the new crop is now in the ground. The crop report says this year’s start is five days behind last year and three days behind the five-year average for corn planting.
