Well I figured I should start one of these as there appears to be an embedded supercell in the line in C MN right now over Southern Mille Lacs County. Also, some cells beginning to pop up a little south of that as well.

Should be interesting to see if anything can get out by itself a little bit over the next 3 or 4 hours.

An isolated cell going up a little more quickly now about 50 wnw of Minneapolis. New PDS Tornado Watch out for the area.

Sitting in Cresco Iowa right now with Joel Wright getting some updated info. Liking the new PDS watch. The grunge we've been in all day is finally starting to break up and surface winds are picking up.

Dewpoints pushing the mid 70s out in central Iowa with surface winds still backed pretty nicely at near due south. A couple cells already firing up in Minnesota as Alex already pointed out.

We're gonna play the southern edge of the the watch where the best moisture and instability is juxtaposed with the better helicity values to the north.

With a few more hours of good heating ahead, this should be a damn good afternoon and evening...

Well, I guess we've got some tired folks, or perhaps those just trying to get to their target today - but for an armchair like me today, we'll try to keep this NOW thread going, and acknowledge the persistent sup (68 dbz / 69 VIL) near Scott City, Kansas now. Has show a couple of meso signatures through its life, but still seems fairly persistent.

Surface low in SE CO slowly but surely deepening and surface winds out ahead starting to back w/ time. Looks like some more treats in store today for those out on their chasecation; particularly hope our international friends are able to see some action today.

Tornado warning on the scott city cell...looks like is starting to turn right.

 

[Joey Ketcham]

Can we add Arkansas and Missouri to this?

Tornado watch extending from Oklahoma northeast into Missouri, 2 very good looking storms in NW Arkansas that'll be pushing into Missouri showing some rotation within the storm.

 

[Eric Flescher]

Scott city hail yes no indication of tornado yet

Nowcasting :
Scott city has big hail - no indication of tornado yet though . Another cell is due West

Tornado warning on the scott city cell...looks like is starting to turn right.

 

[Benjamin Smith]

That cell to the NE of Scott City KS looks to have some rotation in it. TVS signature just came up on the last couple of scans.

Edit:

Rotation seems to have backed off a little bit, even though TVS signature is still present.

 

[Tyler Yarnell]

Dennis Sherrod has a nice wall cloud on his cam on the cell west of Great Bend

 

[Kenny Drake]

Cell south of St. Cloud, MN is starting to get it's act together. Good mid-level rotation per KMPX radar.

 

[Alex Lamers]

Yep, was just going to post about that Kenny. Looks to be organizing quickly. Getting an appendage on the lowest two cuts now.

Confirmed torando on the ground Northwest of Amarillo, TX. TVS shows 191 knots of shear. Wow.

 

[HAltschule]

Also...an enormous wall cloud near the grouind on JF Massicotte's streaming webcam. It is very close to the ground and must be at least 1/2 mile wide.

EDIT: There are several houses very close to this near-tornado. I hope the tornado sirens are wailing!!! (Maybe JF should start honking his horn like crazy to let these people know. There's a new business idea...mobile tornado warning network).

 

[Tyler Yarnell]

Huge rotating wall cloud on the La Crosse, KS cell

 

[Derek Weston]

Supercell with a major hook echo and huge hail just NW of the twin cities.
