High Risk Of Severe Weather Saturday (Nebraska, Kansas, Oklahoma, Iowa)

The Storm Prediction Center has predicted a slight chance of severe weather for parts of Texas and Oklahoma this entire week, thus it should come as no surprise that the weekend holds the best chance of dangerous severe weather.

The Storm Prediction Center has issued an upgraded, high chance of severe weather from central Oklahoma through eastern Kansas (see image below). In addition, there is a moderate risk of severe weather from western Texas through southern Iowa, and a slight risk in the greater area from central Texas through southern Wisconsin.

I cannot stress the severity of this situation enough. Residents living in these regions should prepare for severe weather on Saturday.

Throw in strong surface-level winds at a 45 degree angle to the jet and you have the ingredients to incorporate rotation.

Thank you for the great posts DB! I'm in western Oklahoma and looking to my North and East I can see huge supercell Mammatus clouds.......I think most of the activity today will be East of me, but I have my storm cellar door unlocked and ready. Pleasr keep the posts coming...thanks.

From a blog post at wunderground:

Significant Tornado Parameters are expected to be near 25 this evening. This is the highest values we have seen since April 27 when there was a value of 37.

Hmmm...I think maybe I’ll go check out the supplies in the basement...could get wild and wooly up our way later in the day.

Just got in from getting all of my patio furniture and outdoor stuff secured. I do have a man cave and am heading down there to get that prepared. Hoping all of this stuff they are talking about misses us.
My wife has to lector at 5pm mass. Dont wanna leave my dogs alone but its only for an hour.

From the Warning in northern Kansas. It's getting more organized.

Check out the dew point map in post 30 and how much the dew points have juiced up in Oklahoma since I posted it.

Another joined it

Wow.

[FourPeas]

Growing fast, too.

I’m up in Minneapolis-St Paul. We’re on the far northern fringe of getting any sever weather. I can feel a large uptick in the dewpoint from last night.

I can only imagine what it feels like down in the targets area of kansas and Nebraska.

Not only does that mean more juice for thunderstorm development, but also strong southerly winds at the surface for the jet stream to ride over and create rotation.
