oh yeah, can we get a theta-e/streamline data set is possible?

After witnessing the continued decrease of involvement in the SpotterNetwork staff in serving SN members with troubleshooting issues recently, I have unilaterally decided to terminate the relationship between SpotterNetwork's support and Stormtrack. I have witnessed multiple users unable to receive support weeks after initiating help threads on the forum. I find this lack of response from SpotterNetwork officials disappointing and a failure to hold up their end of the agreement that was made years ago, before I took over management of this site. In my opinion, having Stormtrack users sit and wait for so long to receive help on SpotterNetwork issues on the Stormtrack forums reflects poorly not only on SpotterNetwork, but on Stormtrack and (by association) me as well. Since the issue has not been satisfactorily addressed, I no longer wish for the Stormtrack forum to be associated with SpotterNetwork.
I apologize to those who continue to have issues with the service and continue to see their issues left unaddressed. Please understand that the connection between ST and SN was put in place long before I had any say over it. But now that I am the "captain of this ship," it is within my right (nay, duty) to make adjustments as I see necessary. Ending this relationship is such an adjustment.
For those who continue to need help, I recommend navigating a web browswer to SpotterNetwork's About page, and seeking the individuals listed on that page for all further inquiries about SpotterNetwork.
From this moment forward, the SpotterNetwork sub-forum has been hidden/deleted and there will be no assurance that any SpotterNetwork issues brought up in any of Stormtrack's other sub-forums will be addressed. Do not rely on Stormtrack for help with SpotterNetwork issues.
Sincerely, Jeff D.

Driving directions to Osceola, IA 97.7 mi – about 1 hour 30 mins...
Time to go, but again, not to far, I want that southern edge.

I just got into the game. But my plans for the day were to leave Springfield Mo and head up I-44 to Rolla, MO. Then north up 63 hwy to Columbia. My destination in ne MO up near KIRKSVILLE

Just left Omaha and now moving to Ft.Dodge,Ia. We have already nice convection but I still hope in some isolated cells ahead of the low.
Just because I like you...and because I have the capabililty, I went ahead and got some data and made some graphics for that. It wasn't easy, and you'll only get it for 18-21Z, but here are the 18Z and 19Z analyses for surface theta-e and streamlines
18Z Surface Theta-e and Streamlines
19Z Surface Theta-e and Streamlines (note: the analyses can only be considered to be fully accurate at 18Z and 21Z, because that's all the datasets I got had. I was able to make 19 and 20Z analyses by linearly interpolating between the two times, so just know that's what you're looking at when you view 19Z and 20Z analyses of this product)
Hopefully I'll be able to get the 20Z update out by early afternoon. I plan on having up to 22Z updates out by late tonight, so stay tuned!

I'm inclined to stay on the more isolated tail-end action in sw IA. Even though there was a tornado reported in northern IA that radar looks messy and not something I would have chased.

I'm making the 1 hour 15 minute drive out of Nebraska City to Bedford, IA. That should put me there around 2030ish.

Hey Buddy! Can Brian and I ride with you. We are broke and out of gas. You need to pick us up in Anderson, Mo. before you head up. Also, can you buy our beer after the chase?
Well, we are still hanging out here at the southern extent of this line debating whether to cross over into Oklahoma a tad. Wondering if this is going to be one of these Illinois/Tennessee valley events?
20Z Update
As of 3:00 PM CDT, the tornado in Kossuth Co., Iowa was still on the ground, now southeast of Ledyard.
Satellite:
National IR
Central Plains visible
Mid-Mississippi Valley visible
Radar (with watches):
National
Kansas
South Dakota
Iowa
Illinois
Surface:
Northern US
Southern US
Wind profilers:
Lower troposphere
Upper troposphere (not available this hour)
20Z Surface Theta-e and Streamline analysis
Wayfaring map as of approximately 2000 UTC: http://www.wayfaring.com/maps/show/60975. Looks like most people are now clustering in southwest Iowa.
-At 3:10 PM CDT, a brief tornado touchdown was witnessed near Blue Earth, MN in Faribault County.

The line has come to me over by DeSoto and I'm now on the road playing it. May head for the new cell formation at the tail end. However, I also note low-level shear building across the river in western IL. Not sure that'll be a practical option, but at this point, with lots to think about, I'll play things by ear.

I haven't made it to Bedford yet but with the latest data coming in, I will be proceeding through Bedford and to the N to get in position for this second wave of cells moving into IA. I am going to try to make it to Creston, IA. Hoping to be there around 22z

Not liking too much Iowa convection...I hang on here in Mason City, Ia, hoping to see some isolated stuff.

My confidence in a second round near me is very low at the moment. Heading to the I-35 corridor just south of Des Moines. It's still pretty early, so we'll wait and see.

Show me in Mt. Ayr, IA Good north south option here at Hwy 2 and US 169. Winds seem to be a little better back further east.
