UPDATED: Tornado watch SE of Lubbock until 4 a.m.

Here is current radar:

 

Updated 10:15 p.m. - A new tornado watch has been issued for areas east and south of Lubbock, including Ralls, Dickens, Tahoka, Post, Lamesa, Gail and Snyder. The main risk with storms will be hail and wind, though a few tornadoes are possible.

We're also still watching for more lift to move in from New Mexico, since the big storm system is still west of us. The dry line has retreated west. Where you see the dew point in the 50s and 60s there's humidity for possible storm development.

South Plains dew point

But it's not a certainty. We'll simply wait and see if any storms can develop along the dry line west of Lubbock. And we'll keep an eye on the cluster of severe storms over the southern South Plains. Storms are moving NE around 40mph.


Updated 7:46 p.m. - We watched a couple big storms east of Lubbock. It appears one produced a tornado near Dickens then again in eastern Dickens County and possibly west of Guthrie. There was also significant rotation near Spur from another storm. These storms also contained some golf ball-size hail, including another one that prompted a tornado warning near Lake Alan Henry.

The dry line has retreated just west of Lubbock. We're waiting for some upper-level lift to arrive from the west. It may provide the lift for some more storms, but we really don't know at this point. If storms can develop, they'll likely turn severe. But we don't yet know if the atmosphere has been too worked over to support another round of storms. 

Because of this possibility, the NWS has extended the tornado watch a couple hours. It now runs until 10 p.m.


Updated 4:48 p.m. - Scattered severe storms are moving NE across the area. Around 4 p.m. we had a storm produce a 75mph gust near New Home and looks like pretty widespread 60 to perhaps 70mph wind through the eastern half of Lubbock.

It caused some power outages both to LP&L and SPEC customers, though many of the customers got power back pretty quickly.

Additional storms are expected next few hours. The primary risk on the South Plains will be large hail, though some storms will produce damaging wind. Tornadoes are possible, though like we've mentioned through the day, the greater tornado risk is NE of Lubbock, in the northern Rolling Plains and Eastern Panhandle.

There is still a lot of instability and a lot of shear, plus stronger lift will move in overhead. This means we still have hours to go on these storms. 


The Storm Prediction Center in Norman, OK has issued a PDS - Particularly Dangerous Situation - Tornado Watch until 8 p.m. for Lubbock and roughly the eastern half of the area, counties in blue.

Here in Lubbock, our main concern is very large hail, though any storm that forms will have the potential to produce a tornado. The tornado risk increases significantly east and northeast of Lubbock.

You need to have your tornado safety plan ready now. Once a tornado warning is issued for your area it's time to use that plan. Now would also be a good time to get out of a mobile home or weak structure to something safer. Storms will be moving 40 to 55mph, meaning there may be little time to get to a safe place once storms have developed.

We expect storm development over the next hour or two, with storms quickly going from nothing to major supercells.  Here is the text from the SPC:

1235 PM CDT Mon May 20 2019

The NWS Storm Prediction Center has issued a

* Tornado Watch for portions of
West Texas including much of the Panhandle

* Effective this Monday afternoon and evening from 1235 PM until
800 PM CDT.

...THIS IS A PARTICULARLY DANGEROUS SITUATION...

* Primary threats include...
Numerous tornadoes expected with a few intense tornadoes likely
Widespread large hail and scattered very large hail events to 4
inches in diameter expected
Widespread damaging wind gusts to 70 mph likely

SUMMARY...Intense tornadic supercell thunderstorms are expected to
develop across west Texas as the eastern half of the Texas
Panhandle. In addition to the risk of strong tornadoes, very large
hail and damaging winds are likely in the strongest cells.

The tornado watch area is approximately along and 55 statute miles
east and west of a line from 50 miles east northeast of Amarillo TX
to 35 miles east of Big Spring TX. For a complete depiction of the
watch see the associated watch outline update (WOUS64 KWNS WOU7).

PRECAUTIONARY/PREPAREDNESS ACTIONS...

REMEMBER...A Tornado Watch means conditions are favorable for
tornadoes and severe thunderstorms in and close to the watch
area. Persons in these areas should be on the lookout for
threatening weather conditions and listen for later statements
and possible warnings.
