This morning, the Storm Prediction Center has upgraded all of western Iowa to an enhanced risk of severe weather. Isolated thunderstorms are expected to develop later on this afternoon ahead of a cold front, and will eventually line out.

Storms will begin to form across northwest Iowa after 5pm Saturday. These storms initially will be isolated, which is when the greatest potential for all modes of severe weather will exist. This includes very large hail, damaging winds, and tornadoes.

The Storm Prediction Center has outlined a large area of an enhanced risk for tornadoes. If you live within the yellow shaded area, or the 10% risk, this places you at the highest risk of a tornado. This includes the cities of: Omaha, Carroll, Spencer, Cherokee, Algona, Fort Dodge, Red Oak, Atlantic, Sioux City, and Shenandoah.

It does appear as storms move off to the east, that they will begin to line out as the sun goes down. This will transition the severe threat over to a damaging wind threat. A few embedded tornadoes may still be possible, and this is why a 5% tornado risk extends through much of central Iowa.

You will want to make sure to stay tuned to the weather today, as it will be rough going later on in the afternoon. We will have our teams out in the field providing live updates. Make sure to follow all of our sources, as we will be updating you with the very latest information. You can find us on Facebook at the Iowa Storm Chasing Network, on Twitter at @IAStormChasing and on Instagram @iowachase. I will also be updating my twitter page with extra material of behind the scenes as we track this severe weather threat @stormchaserzach.
