Valid 231200Z - 241200Z

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

....SUMMARY...
Severe thunderstorms are not expected on Wednesday.

....Synopsis...

An upper trough over the Rockies will deepen and shift east over the
Plains Wednesday and Wednesday night. As this occurs, weak low
pressure will develop over the southern Plains. Weak southerly
low-level flow will allow for meager northward transport of Gulf
moisture, with surface dewpoints increasing to the low 50s F across
central TX and the low 60s along the TX coast. A cold front will
shift east/southeast, extending from near northeast KS into western
TX by Thursday morning. Some showers may occur over central/northern
TX in this weak warm advection regime ahead of the cold front, but
poor boundary-layer moisture and scant instability will likely limit
thunderstorm potential overnight Wednesday/early Thursday morning.

Isolated thunderstorms are possible once again across parts of the
FL Peninsula where rich boundary-layer moisture will persist.
Nebulous forcing over the region, along with weak instability and
modest vertical shear, will preclude severe potential.
