3 PM Update: Severe Thunderstorm Watch #266 has been issued to include portions of extreme western Iowa until 10 PM.

2:30 PM Update: Severe Thunderstorm Watch #265 remains in effect for portions of northwestern Iowa until 7 PM. Currently a small line of thunderstorms has continued to evolve as it enters a more favorable environment with the latest radar scans indicating continual expansion and strengthening. Currently severe thunderstorm warnings are issued for Yankton county South Dakota, and Cedar county in Nebraska. These two cells should continue to move eastward and cross into the state of Iowa before 4 PM.

More development is expected to the south of this current line and work into the state this afternoon. Both large hail and damaging winds are likely with the storms this afternoon for northwest Iowa.

More thunderstorms will continue to work into the state tonight, with the potential for damaging winds and large hail. Some parts of the state may see more than one round depending on how and where storms develop. More updates as we continue through the afternoon/evening and overnight will address these issues.
