...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms may occur today across parts of the lower
Colorado River Valley and southern Great Basin. Severe thunderstorms
are not expected.

...Synopsis and Discussion...
Thunderstorm chances appear minimal east of the Rockies today with
surface high pressure dominating much of the central CONUS and
offshore flow continuing over the Gulf of Mexico and western
Atlantic. Isolated showers and thunderstorms off the coast of south
FL this morning will continue moving southeastward over water in
tandem with a surface cold front. Large-scale upper ridging will
prevail over the western CONUS today as a weak, closed upper low
migrates slowly from CA to the Great Basin. Even though low-level
moisture and instability will remain quite limited, isolated
thunderstorms appear possible across parts of the lower CO River
Valley and southern Great Basin through the period.
