CORRECTED FOR TORNADO WATCH

The severe weather threat for Tornado Watch 146 continues.

SUMMARY...Severe threat continues across western/central Oklahoma
into northwest Texas.

DISCUSSION...Latest satellite imagery suggests large-scale ascent is
gradually spreading east across the southern High Plains, per
thickening mid-high cloudiness noted into the TX Panhandle. Later
this evening the mid-level speed max will round the base of the
trough and translate into southwest OK. LLJ will strengthen ahead of
this feature along the I35 corridor along with low-level shear.

Southwest-northeast oriented corridor of convection, currently
observed from northwest TX into southwest OK, may not move
appreciably east over the next few hours until large-scale forcing
shunts this region downstream later tonight. Upscale growth may
occur as the aforementioned jet approaches in conjunction with the
LLJ. Environmental parameters continue to favor supercells, and
tornadoes, but some of this activity may exhibit linear
characteristics along with clustering.

Overall, severe threat is expected to linger well into the overnight
hours with a gradual shift east later this evening.
