To quote Heath Ledger's Joker: "And here we go."
 
Area of very weak rotation over North Johns area (borders West Birmingham). Is anyone reporting hail there? The ZDR is showing a spike in that area.
Just curious.

It would appear that storms back in eastern Texas are becoming more discrete. The one that's about to cross the TX/LA border bears watching.

The Laurel rotation is still broad and weaker, the lowest scan elevation is ~6300ft.

Rotation has improved with every new scan. It won't be long until it drops something.
 
Rotation has really tightened up the last couple of scans (with the obvious caveat of distance from the radar)

Mesoscale Discussion 0202
NWS Storm Prediction Center Norman OK
1202 PM CDT Wed Mar 17 2021

Areas affected...Portions of southeast Mississippi and southwest
Alabama

Concerning...Tornado Watch 29...

Valid 171702Z - 171800Z

The severe weather threat for Tornado Watch 29 continues.

SUMMARY...A strong tornado threat will increase from Wayne county,
Mississippi to Marengo and Wilcox counties in Alabama over the next
1-2 hours.

DISCUSSION...Shower activity through the morning has continued to
deepen and a strong storm has developed in Jones County, MS. This
storm has quickly exhibited low-level rotation which is indicative
of the favorable low-level shear profile in this region. SPC
mesoanalysis shows an area of 300 to 400 m2/s2 of 0-3km SRH in this
region which is a result of southeasterly surface winds in local
observations in this area and a 50 knot south-southwesterly
low-level jet around 1.5km to 2km sampled by the KMOB and KDGX VWP.
The ongoing storm in this region in addition to any subsequent
development could pose a significant tornado threat given the
aforementioned favorable low-level shear profile and STP values
around 2 to 3.

SPC just issued a localized MD, highlighting the threat of strong tornadoes increasing, specifically near the strengthening TOR warned storm in SE MS

Just a note - if you have satellite television like I do, or if your cable goes out, you can stream The Weather Channel on Roku or other streaming devices, and local stations should be streaming as well when they go to full on-air weather coverage. You can also pick up local TV stations over the air using a simple antenna. Heavy rain may cause some dropouts though.
