Storms should reach Hammond between 2 and 6 am, in general all modes of severe weather are possible.

this is for the 2nd cell by Anacoco that's colliding with the tornadic warned cell

quote:

The National Weather Service in Shreveport has issued a

* Severe Thunderstorm Warning for... Southern Natchitoches Parish in northwestern Louisiana... Southeastern Sabine Parish in northwestern Louisiana...
* Until 615 PM CDT
* At 514 PM CDT, a severe thunderstorm was located near Anacoco, moving northeast at 30 mph. HAZARD... 60 mph wind gusts and quarter size hail. SOURCE... Radar indicated. IMPACT... Hail damage to vehicles is expected. Expect wind damage to roofs, siding, and trees.
* Locations impacted include... Natchitoches, Provencal, Kisatchie, Cloutierville, Flora, Bellwood, Chopin and Gorum. PRECAUTIONARY/PREPAREDNESS ACTIONS... For your protection move to an interior room on the lowest floor of a building

That tornado warning needs to be moved south. That cell you're talking about is taking over and turning right

The National Weather Service in Shreveport has issued a

* Tornado Warning for... Southern Natchitoches Parish in northwestern Louisiana... East central Sabine Parish in northwestern Louisiana...
* Until 615 PM CDT
* At 522 PM CDT, a severe thunderstorm capable of producing a tornado was located near Hornbeck, or 7 miles north of Anacoco, moving northeast at 30 mph. HAZARD... Tornado and quarter size hail. SOURCE... Radar indicated rotation. IMPACT... Flying debris will be dangerous to those caught without shelter. Mobile homes will be damaged or destroyed. Damage to roofs, windows, and vehicles will occur. Tree damage is likely.
* Locations impacted include... Natchitoches, Provencal, Kisatchie, Cloutierville, Melrose, Flora, Bellwood, Chopin and Gorum. PRECAUTIONARY/PREPAREDNESS ACTIONS... TAKE COVER NOW! Move to a basement or an interior room on the lowest floor of a sturdy building. Avoid windows. If you are outdoors, in a mobile home, or in a vehicle, move to the closest substantial shelter and protect yourself from flying debris.

basically just replaced the severe thunderstorm warning I just posted with a tornado warning

Am I seeing a potential TVS or debris ball east of Hornbeck and north of Anacoco?

Hard to say for certain, but it could be a debris ball.

The cell about to roll into the Anacoco area is warned too far north imho. Looks like a tornado is forming up and riding to the South of the current warning. ETA: rotation is still rather broad but bright greens and reds on the velocity.

makes you wonder if that's the line of demarcation between the NWS Shreveport office and the NWS Lake Charles office and Lake Charles handed it off thinking they were done with it and haven't picked it back up yet

Pretty sure Fort Polk has an office and they'd be the ones putting out warnings. Could just be a radar station I guess.

It's a messy set up right there. Lots of storms starting to fire up. It's one to keep an eye on as it progresses.

You looking at the velocity radar? Because I'm seeing evident rotation out of fort Polk.

I'm on severestudios and they only have the precip radar

I don't think it's real good... could use something else to look at

Id say there's a tornado going right over Anacoco now, and it's unwarned per my radar app.

rt3 the NWS site has radar with precip and velocity for every station they operate. Get on the fort Polk radar and check out the velocities. Tight green and red right next to each other is a good sign of a tornado.

Areas affected...Portions of LA...western MS...southeast AR

Concerning...Tornado Watch 98...

Valid 292250Z - 300045Z

The severe weather threat for Tornado Watch 98 continues.

SUMMARY...The risk for severe thunderstorms and tornadoes continues
across Tornado Watch 98, and will spread east-northeastward and
northeastward through the evening and overnight hours. An additional
Watch will likely be required prior to the 02Z expiration of Watch
98.

DISCUSSION...Clusters of thunderstorms, including embedded rotating
updrafts and bowing segments, continue in the vicinity of the lower
Sabine Valley. Inflow for this activity is characterized by around
500-2000 J/kg of MLCAPE (higher buoyancy amid richer moisture with
southward extent), based on modifications to the 18Z Lake Charles
and Shreveport observed soundings. This activity lies within the
warm sector of a broader extratropical cyclone, within which modest
positive theta-e advection will continue during the next several
hours.

As a result, convection will continue to spread east-northeastward
and northeastward into the evening and overnight hours. This will
occur while ascent attendant to the right-entrance region of a
midlevel speed maximum encourages both (1) the maintenance of at
least modest instability, and (2) a low-level mass response
supporting moderate low-level shear and isentropic ascent. Moreover,
with 40-55 kt of effective shear attendant to the speed maximum,
organized convective modes will continue to be favored.

While damaging winds and sporadic severe hail will be the primary
concerns with this activity, tornado potential will exist with
embedded supercell structures and meso-vortices. This would
especially be the case as strengthening low-level shear juxtaposes
increasing boundary-layer theta-e through the night. Accordingly, a
new watch will likely be issued from parts of southern LA to the
ArkLaMiss region prior to the expiration of Tornado Watch 98.
