The main threats are strong wind, large hail, and localized flooding due to heavy rain, but isolated tornadoes along the cold front can not be ruled out.
Chris Broyles, a meteorologist with the service's Storm Prediction Centre, said: "The tornadoes are being caused by supercell storms that are being driven by the strong wind shear".
Rain - 2.97 inches in Harrison County near Little Sioux, Iowa.
Wednesday is a First Alert Weather Day due to the threat of isolated severe storms in our eastern counties.
Small said the potential for severe weather will eventually move on, but that depends on when the stalled boundary moves out of the area.
- A marginal risk for a swath that includes York and Denison, Iowa.
Officially, parts of the Tulsa metro are under the "slight" to "marginal" risk categories for severe weather on Wednesday into Thursday morning. The entire line is expected to march eastward however, individual storms will probably move to the northeast. Enhanced risk suggests more numerous and persistent storms. Rain and storms affect the I-20 corridor as a cold front moves through Friday but the severe risk appears to be quite low. Tornadoes, hail to the size of apples - a shade bigger than baseballs - and wind gusts up to 80 miles per hour are all possible as storms develop Wednesday afternoon. Expect a high in the upper 60s. Plus, a few showers or storms can't be ruled out.
Today other than a few non severe storms this morning we will be mostly cloudy today with highs in the upper 70s-mid 80s.
If the heavy rain hits certain spots repeatedly, momentary flooding is possible.
Saturday night: Mostly clear, with a low around 56.
Sunday: Sunny, with a high near 83.
