Tornado Outbreak Possible to End the Week

day1otlk_1200 After Thursday’s severe weather in southwest and north central Iowa, another round is expected in the eastern half of Iowa on Friday.  Primary threat is expected to be the development of tornadoes.

The Storm Prediction Center in Norman, OK has posted a slight risk for the eastern half of the state for Friday afternoon and evening.  The front that served as the focal point for thunderstorms in western Iowa Thursday will push into the eastern half.  Ahead of it, warm and unstable air is expected to collect over the area. 

day1probotlk_1200_torn Taking a look at the breakdown between wind, hail and tornadoes, it appears the threat of tornadic development is the primary concern.  Shear profiles should be quite impressive over the area.  Once storms begin developing in the mid afternoon, supercells should quickly form and tornadoes shouldn’t be too far behind.

Behind the tornado threat, large hail between 2-3” is possible with the strongest storms.  Storms should then move out of the area by early to mid evening into Wisconsin and Illinois. 

All in all it is shaping up to be a pretty active Friday.  Storm chasers will likely be out throughout the state tracking the storms.  Of concern is the fact some storms could move rather quickly to the northeast as they develop, making it difficult to chase.  Once supercells take shape, some storms could slow down which would help in tracking them.

We’ll pass along the latest as we get it in the coming hours.  Once chase teams deploy we’ll pass along all information here on the blog.
