Areas affected...Portions of southwestern KS and northwestern OK

Concerning...Severe Thunderstorm Watch 405...

Valid 280147Z - 280315Z

The severe weather threat for Severe Thunderstorm Watch 405
continues.

SUMMARY...A small, intense bowing complex will pose a threat for
significant severe wind gusts of 75-100 mph this evening as it
spreads eastward across southwestern Kansas and northwestern OK.

DISCUSSION...Multiple measured severe wind gusts ranging from 65 mph
up to around 100 mph and damage reports have recently occurred in
the OK Panhandle with a small bowing cluster now moving into far
northwestern OK and southwestern KS. Strong inbound velocities noted
from KVNX around 9000 ft AGL along the apex of the bow suggest the
development of a pronounced rear-inflow jet. The thermodynamic
environment in the near term (next 1-2 hours) should remain quite
favorable for significant severe wind gusts of 75-100 mph in a
narrow corridor across far northwestern OK into southwestern and
south-central KS. Instability gradually decreases with eastward
extent into north-central OK and south-central KS along/north of a
stalled surface boundary. The potential for significant severe winds
farther east into these areas beyond 04Z (11 PM CDT) is less clear
owing to the somewhat weaker instability. Still, some severe wind
threat will likely persist tonight as the bowing complex develops
eastward.
