The Storm Prediction Center has posted a slight risk for severe weather in Nebraska Saturday. This risk area includes a portion of western Iowa. Even so, I expect most areas, including western Iowa, to remain dry for most of the day on Saturday.
The closer we get to the evening hours things get a little active out west. Showers and thunderstorms are expected to develop in Nebraska. That development could carry into western Iowa by the early evening hours.
With that in mind, a slight risk for tornadoes is posted. You can see that risk area in the graphic to the right. For the first 3 hours of the severe weather event Saturday Night, tornadoes will represent the primary threat before concern shifts to more straight line winds.
Overall, the greatest risk for western Iowa is the straight line winds. Close to sunset, a wind event could set up shot in Nebraska and make its way into Iowa.
The graphic on the left shows the risk area for strong winds. What happens beyond this point remains up in the air. Of concern is that a strong wind event will last through the evening and overnight hours. If that happens, parts of central and eastern Iowa might also face the threat of strong winds closer to sunrise on Sunday.
We’ll have more on the risk for Sunday in another post this afternoon as things remain rather interesting…
