Areas affected...Portions of southwestern/south-central KS into the
TX/OK Panhandles and northwestern OK
Concerning...Severe Thunderstorm Watch 129...
Valid 290208Z - 290315Z
The severe weather threat for Severe Thunderstorm Watch 129
SUMMARY...Mainly a damaging wind and isolated large hail threat
continues across eastern portions of WW 129. While downstream watch
issuance remains unlikely, a local extension in time of the Severe
Thunderstorm Watch beyond the scheduled 03Z expiration time may be
needed if current radar trends continue.
DISCUSSION...Across southwestern KS convection has organized into a
line with multiple wind gust/damage reports, including a 73 mph gust
recorded at Garden City, KS at 0106Z. Mainly a damaging wind threat
should continue into parts of south-central KS over the next hour or
two before increasing convective inhibition likely reduces the
overall severe threat. Farther south into the central/eastern TX/OK
Panhandles, convection has remained a bit more discrete, with
several supercells producing hail up to baseball size noted. A
downstream watch into northwestern OK and central KS remains
unlikely due to a less favorable thermodynamic environment with
eastward extent, but a local extension in time of WW 129 for an hour
or two may be needed if current radar trends continue.
