...NO THUNDERSTORM AREAS FORECAST...

CORRECTED

...SUMMARY...
Severe thunderstorms are not expected across the U.S. on Saturday.

...Synopsis...
While weakly anticyclonic westerly/west-northwesterly flow aloft
prevails over the eastern half of the U.S. Saturday, an upper trough
will continue moving southeastward across the California and the
Great Basin, toward the Desert Southwest through the period.

At the surface, an evolving cold front is forecast to shift across
Utah and Arizona through the end of the period, while high pressure
prevails east of the Rockies.

While showers will occur over portions of the West, a cool air/steep
lapse rates aloft accompany the upper troughing, instability will
generally be insufficient to support thunderstorms.  A few sporadic
flashes may occur across the region, but coverage is expected to
remain too limited to warrant inclusion of a 10% thunder area.
