....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Thunderstorms are not forecast across the contiguous United States
on Sunday.

....Synopsis...

Fast, zonal mid/upper-level flow will spread across the southern
tier of the U.S. as a midlevel upper trough develops eastward from
the northern Rockies toward the Midwest. Surface high pressure over
the Southeast will maintain a mostly dry boundary-layer. By the end
of the period, weak surface troughing over the High Plains will
result in some modest moistening on southerly low-level return flow
across coastal and eastern TX. However, little instability, and weak
forcing for ascent, will preclude thunderstorm development.
