Looks like a tornado just touched down west of Norman, and then lifted as it reached downtown. Norman police department reporting damage at their station and in downtown.

How well fortified is SPC?

We might have a developing tornado in Anadarko.

They're in a multi-story office building on the Univ. of Oklahoma campus... It looks pretty sturdy.

The new office is fairly new. I imagine it was built to withstand strong winds line the NHC. I watched it being built on my trips to Norman.....MGC

This is in Norman.

Cell is east of Norman and appears to be recycling as it heads toward Shawnee. Pink, Bethel Acres and Shawnee probably should take shelter as if a tornado were approaching, won't be surprised if it tries to drop another one, even though there is only a Severe warning at this time.

Set up wise it's a bit different. 5h vorticity/jet entered a very rich moist air mass in Alabama/MS with virtually no capping. Rare event, as I've mentioned before this set up is more usual to the typical plains outbreaks but with a more jet energy. Entry point is going to be in the Missouri River area but that is farther from gulf source, though can still be violent. Down south bc of SW flow capping will inhibit initiation but storms that do will go severe fast but less in coverage.
