Areas affected...Western/Central OK...Northwest TX
Concerning...Severe Thunderstorm Watch 392...393...
Valid 040026Z - 040130Z
The severe weather threat for Severe Thunderstorm Watch 392, 393
SUMMARY...Strong to severe wind gusts remain likely with an MCS
moving southeast from northwest OK and the eastern TX Panhandle,
along with a separate cluster evolving east across northwest TX.
DISCUSSION...Strong to severe wind gusts of 45-60 kt have been
common over the past couple hours with an MCS centered over
northwest OK/eastern TX Panhandle and an additional cluster near the
I-27 corridor in northwest TX. With 20-25 kt low-level inflow per
area VWP data that should increase slightly through the evening,
strong to embedded severe wind gusts should persist for the next few
hours amid the steep lapse rate (7.5 to 8.5 degree C/km from 700-500
mb) environment sampled by the 00Z AMA and OUN soundings. The MCS
and cluster will merge over northwest TX and likely continue
east-southeast along towards the Red River in OK. Prior to this
occurring, isolated severe hail is most probable within this region.
