WW 240 SEVERE TSTM TX 070240Z - 070800Z
URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 240
NWS Storm Prediction Center Norman OK
940 PM CDT Sun Jun 6 2021
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
The southern Texas Panhandle and South Plains
* Effective this Sunday night and Monday morning from 940 PM
until 300 AM CDT.
* Primary threats include...
Scattered damaging wind gusts to 70 mph possible
Isolated large hail events to 1.5 inches in diameter possible
SUMMARY...Thunderstorms are developing rapidly with the collision of
outflow from New Mexico and the retreating dryline, and storms are
expected to persist as line segments or clusters into the overnight
hours while spreading east-southeastward.Damaging winds and large
hail will be possible with the stronger embedded storms.
The severe thunderstorm watch area is approximately along and 65
statute miles east and west of a line from 35 miles northeast of
Amarillo TX to 60 miles southeast of Lubbock TX. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU0).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for 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. Severe thunderstorms can and occasionally do produce
tornadoes.
&&
AVIATION...A few severe thunderstorms with hail surface and aloft to
1.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A
few cumulonimbi with maximum tops to 550. Mean storm motion vector
28025.

Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0741 PM CDT Sun Jun 06 2021
Valid 070100Z - 071200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF THE SOUTHERN PLAINS TONIGHT...
...SUMMARY...
Strong to severe storms capable of producing hail and strong gusts
are possible across portions of northwest Texas and southwest
Oklahoma through the overnight hours.
...Northwest TX in southwest OK...
Uncertainty remains regarding convective development/evolution this
evening into the overnight hours. CAMs guidance remains consistent
in developing an organized cluster/bowing segment across parts of
the Texas South Plains into northwest Texas/southwest OK overnight.
While the thermodynamic and kinematic parameter space would support
such development, large-scale forcing remains nebulous over the
region. Currently, a small cluster of storms near Clovis NM has
produced a well-defined outflow boundary surging east/southeast
toward the NM/TX border west of Amarillo and Lubbock. There is some
potential that storms could intensify/redevelop along this boundary
as it shifts east into better low level moisture and stronger
instability across the TX Panhandle/South Plains vicinity. Steep low
level lapse rates and moderate to strong instability could support
strong downdrafts and cold pool development, which in turn would
support an increasing threat for damaging winds into the nighttime
hours. However, this scenario remains conditional and uncertain. As
such, will maintain a Marginal risk.
...Upper MS Valley and Lower MS Valley...
Severe potential has diminished across these areas this evening and
the Marginal risk has been removed with this 01z update.
