...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms may develop late Friday night across parts of
central/east Texas to the ArkLaTex vicinity. Severe thunderstorms
are not expected.

...Synopsis and Discussion...
An upper trough will move eastward from the Southwest across the
southern/central Plains on Friday. Gradual and modest low-level
moisture return should occur across parts of central/east TX to the
ArkLaTex vicinity through the period. As large-scale ascent
preceding the upper trough overspreads this region late Friday
night, isolated thunderstorms may develop in a low-level warm/moist
advection regime. Weak instability (MUCAPE 500 J/kg or less) is
expected to preclude a severe risk, with any convection that does
develop likely remaining elevated.
