Areas affected...portions of northwestern Texas

Concerning...Severe Thunderstorm Watch 159...160...

Valid 230357Z - 230530Z

The severe weather threat for Severe Thunderstorm Watch 159, 160
continues.

SUMMARY...Severe gusts may accompany an organized MCS over the next
few hours.

DISCUSSION...An MCS has organized a couple of hours ago, and the
KCDS ASOS measured a southeasterly gust of 47 kts within the
trailing precipitation region, indicating that a localized severe
gust threat may be increasing. This is in agreement with the last
several runs of Warn-on-forecast, which has depicted a severe wind
swath with this MCS along/near the Red River. Given residual MLCAPE
around 2000 J/kg and increasing WAA with a strengthening nocturnal
low-level jet, this MCS may persist, perhaps with severe gusts for
at least a few more hours. Given the approaching expiration time of
the ongoing severe thunderstorm watches, a downstream watch may be
needed pending favorable convective trends against increasing
MLCINH.
