MD 0189 CONCERNING SEVERE THUNDERSTORM WATCH 21... FOR WESTERN NORTH-CENTRAL TX

Mesoscale Discussion 0189
NWS Storm Prediction Center Norman OK
0303 AM CDT Wed Mar 13 2019

Areas affected...Western North-Central TX

Concerning...Severe Thunderstorm Watch 21...

Valid 130803Z - 130900Z

The severe weather threat for Severe Thunderstorm Watch 21
continues.

SUMMARY...Corridor of greater wind damage and QLCS tornado potential
exists across western north-central TX.

DISCUSSION...Recent KDYX imagery has shown a sharpening of the
convective line moving into western north-central TX. This
sharpening is coincident  with the lines interaction with slightly
better low-level moisture and moderate southerly/southeasterly
surface winds. Additionally, VAD wind profiles from KDYX show a
well-defined rear-inflow jet. Interaction between this
well-organized part of the convective line, southeasterly surface
winds, slightly better low-level moisture, and favorable orientation
of the storm motion to the vertical shear suggests a higher wind
damage and QLCS tornado threat within this corridor for the next
hour or so.
