Tornado Warning Lauderdale Co, AL....possible on the ground:

Fred’s station. His team does an excellent job

 

[UncleJuJu98]

Shoot we are starting off early today. And yeah @Ozonelayer that doesn't look good. May be a busy day in Alabama

Yes, they do. I was watching as it went tornado warned

I will say, if tornadoes are dropping now, then any supercells that form later on should have little problem doing the same.

And yeah, semi-discrete line with prefrontals. 16z is pretty bad.

Getting going before the stronger mid-level flow from the streak rolling around the base of the trough even arrives. Impressive. Certainly we could see some nastiness before growing upscale, just feels like hard to avoid a pretty quick more linear mode unless the HRRR is somehow on the right track with the more backed low levels later

Tower camera shows that it lifted a few minutes ago, but there are several lowerings. I'd send a photo but my internet is poop and it takes forever to load. Also, Threet (included in the warning) is a really unique town name! It rolls off the tongue weirdly, but I like it.

 

[OH-IOan]

There you go.

Lauderdale Co storm restrengthening. Big lightning uptick

HRRR continues to have significant updraft swaths in north and north-central alabama

The NOAA weather radios in these areas are down today through Wednesday for scheduled maintenance. Areas in Tennessee, Kentucky , Alabama, South Carolina and Colorado, please have other ways to receive watches and warnings. We will be posting extra watches and warnings today here on our page and on our x/twitter page.

Watch forthcoming for parts of AR, TN, MS. Strong tornadoes possible.

1234 PM CDT Tue May 20 2025

Areas affected...Eastern Arkansas into western Tennessee and
northwest Mississippi

Concerning...Severe potential...Watch likely

Valid 201734Z - 201930Z

Probability of Watch Issuance...80 percent

SUMMARY...Thunderstorm development is anticipated in the coming
hours across central to eastern Arkansas. Storms will intensify as
they spread east towards the MS River, and will pose a threat for
all hazards. Watch issuance is expected as initiation becomes
imminent.

DISCUSSION...GOES imagery shows slow vertical development of
agitated cumulus along and ahead of a cold front across southern to
central AR with at least one deeper convective tower exhibiting
occasional lightning. This comes amid steady destabilization of a
residual cold pool ahead of the front where temperatures are warming
into the upper 70s and low 80s and MLCAPE climbs into the 2000-2500
J/kg range. Gradual elimination of lingering inhibition will likely
lead to steady growth/intensification of convection through
mid-afternoon. A 60-65 knot mid-level jet will promote storm
organization, though it remains somewhat unclear exactly when
convection will become sufficiently deep to realize the sheared
environment and pose a severe threat. However, by late afternoon
thunderstorms will likely reach sufficient intensity and
organization to produce severe winds, large hail and tornadoes
(including the potential for 2-3 inch hail, and strong tornadoes
with more discrete cells). Latest guidance suggests this is most
probable along the MS River across eastern AR into adjacent portions
of TN and northwest MS. Watch issuance is expected as soon as
convection begins to show signs of steady deepening/intensification.
