NORMAN, Okla. (AP) – The Storm Prediction Center says severe thunderstorms are possible Saturday across the southern and central Plains as a cold front rolls out of the Rockies. Humid air could extend well into the Mississippi and Missouri valleys, making the atmosphere ripe for storms. The forecasters say the greatest chance for bad weather is from eastern Oklahoma to northeastern Iowa, including parts of Kansas and Missouri, but that storms are also possible from Texas into Minnesota and Wisconsin.

Supercells with hail and possibly tornadoes could occur, especially before the storms form a squall line.  After a squall line forms, high winds could be worrisome.  The prediction center, based in Norman, Okla., categorizes the area from Austin, Texas, to Minneapolis and Milwaukee and Chicago as having a slight risk of severe storms.

The latest forecast shows severe weather making its way into Iowa tonight (Friday). National Weather Service Meteorologist Craig Cogill said late Thursday afternoon, that the initial primary threat will be heavy rain and hail, but the system has the potential to cause more serious damage on Saturday. “Right now, it looks like the best threat of severe weather is going to be across western Iowa where damaging winds, large hail and possibly a few tornadoes – especially during the late afternoon and evening hours – will be possible,” Cogill said. The much needed rain could range from one to two inches. If tornadoes touch down over the weekend in Iowa, it wouldn’t be unprecedented.

“Usually we see tornadoes in the fall about every other year or every third year,” Cogill said. “Certainly, it’s not a tornado season like we see from late April through June, but it’s not totally out of the question to see fall tornadoes.” The storm system is expected to leave Iowa Saturday night. The forecast for Sunday calls for highs mainly in the 60s.
