An enhanced risk of severe weather has been issued from central Iowa back into southwest Iowa. Main risks for severe weather today will be large hail and damaging wind. However, an isolated tornado threat will be possible in the enhanced risk, but this threat will be very conditional.
The greatest tornado threat will extend from Des Moines, back through southwest Iowa. A few locations in the enhanced risk of tornadoes includes: Creston, Red Oak, Clarinda, and Corning. This tornado threat will only exist if we get a couple hours of clearing early this afternoon. If we do not get a break in the rain before the second wave moves through this afternoon, then the tornado threat will diminish.
The next concern will be for flash flooding later on this evening. Because of the thunderstorms that are expected throughout the day today and into tonight, a flash flood watch has been issued from 10am this morning through late tonight. These storms will be capable of producing heavy rain at times, causing widespread total rainfall amounts ranging from 2 to 4 inches with locally higher amounts certainly possible. Rainfall rates as high as two inches per hour at times may lead to flash flooding and rises in area rivers.
If you live across central and southwest Iowa, pay close attention to the weather this afternoon, as if clearing takes place as the models are showing, this afternoon will be bumpy. We will be here all afternoon to track this severe weather threat so check back here for all of the very latest developments.
