...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated to scattered thunderstorms are possible across portions of
central Texas.
...Synopsis...
The upper low/trough over the Southwest and northwest Mexico will
minutely shift east on Friday. As this occurs, modestly enhanced
mid/upper southwesterly flow will overspread the southern Plains.
Boundary layer moisture will remain scant across TX due to prior
cold frontal intrusion into the Gulf of Mexico. However, a few
elevated thunderstorms will be possible across central TX.
Increasing midlevel moisture coupled with steep midlevel lapse rates
and cool temperatures aloft will support meager elevated
instability. Subtle large-scale ascent associated with the eastward
creeping upper trough may be sufficient to aid in isolated lightning
flashes. Severe thunderstorms are not expected.
