***UPDATED AT 10:50 AM***
Good morning everyone. As some of you know the Storm Prediction Center has shifted the moderate risk northward into the area. I am currently examining data and will have a detailed post in the coming hour. The placement of the warm front will be key to our severe weather chances as well as the amount of moisture. Stay tuned and I will get to your questions this morning as soon as I am finished with the post.

Good afternoon and evening bloggers. Thanks for checking in today. A big thank you to the students at John C. Thomas Elementary School in Nixa who invited me out for a school visit about severe weather safety. They were a great group of kids and I hope they invite me back yesterday. And who knew that we have quite the blog following at Thomas. I was able to meet a few regular bloggers and really enjoyed myself!
The weather picture for tomorrow is not really all that clear cut and is not a classic severe weather setup by any means, but it looks as if the southern portions of our viewing area (i.e. northern Arkansas) could see a rather active severe weather day tomorrow.
First though, tonight looks pleasant as temperatures drop into the lower 50s after a fairly mild evening depending on where you are. Look at the temperature difference between northern Arkansas/southern Missouri and areas to the north!

Tomorrow we will start out with scattered clouds across the area. Here is the expected surface setup in the central part of the US.

Showers and thunderstorms will form along and north of the warm front, near the low, and along the cold front. Instability is very limited north of the warm front (generally areas north of Highway 60) but it should be sufficient enough for severe thunderstorm development after 1 PM tomorrow across most of southern Missouri. Notice the arae of greatest instability (in excess of 3,000) is centered across southeast Oklahoma.

My main concern lies with what may happen in northern Arkansas. Much of Arkansas will be in the warm sector and will also have sufficient amounts of shear for supercell thunderstorm formation. Much of Arkansas is in a moderate risk and very large hail, damaging winds, and tornadoes will be possible.

It's an interesting scenario and we'll see how the mesoscale affects play out tomorrow. Again, severe weather is possible areawide, but primarily across northern Arkansas. I'll have an update very late tomorrow morning and I'll be updating the blog throughout the afternoon. If severe weather does develop we'll also open the chat. Feel free to ask questions in the blog tonight and I'll get to them as soon as I can.

Does anyone notice how some models have changed their minds putting the warm front to Central Missouri. Also, moderate risk may be expanded further north/northwest ward?

Good Morning everyone! Has anyone noticed as of 7 am this morning, SPC has substantially moved the moderate and slight risks north and northwest. A moderate risk of severe weather is currently in place over southern Missouri. I think more instability has developed as there is full sunshine at my house.

what do you think is the chance for severe weather south of a line from cassville to taneyville?

Hey, Josh, when do you APPROXIMATILY think the rain/thunderstorms/severe weather will begin and end tomorrow for Greene County? I have heard that parts of Arkansas and surrounding areas have been upgraded to a high risk area, is this true? Thanks for all of your hard work!!! ~WESTON :)

Thanks for the post Josh. Sounds like Bolivar will not be under the gun. I will pray for those in Arkansas-they look to get most of it by what you showed. Will check later for updates. Friend, Val

Do you think springfield will be under the gun for tornados or do you think it is a small threat?
