....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not expected tonight.

....01z Update...

Southwestern US trough has advanced east of the lower CO River
Valley early this evening. This feature is forecast to eject across
the southern Rockies, with negligible height changes expected
along/south of the front currently draped along the I-20 corridor
across TX. Even so, scattered-numerous showers, with isolated
flashes of lightning, extend from far west TX-OK-AR-northern MS.
This activity is primarily elevated and driven by low-level warm
advection. 00z sounding from MAF exhibited near-surface-based
buoyancy with roughly 600 J/kg MUCAPE. LZK also exhibited around 500
J/kg MUCAPE if lifting a parcel around 1km AGL. While deep-layer
shear is strong along the boundary, sustained warm-sector updrafts
will prove difficult tonight. Severe threat appears minimal through
sunrise.
