Valid 281200Z - 291200Z

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

....SUMMARY...
Severe thunderstorms are not expected across the Contiguous U.S.
tomorrow (Sunday).

....Synopsis...
Broad yet weak mid-level troughing will overspread the western U.S.
while upper ridging dominates the CONUS east of the Rockies tomorrow
(Sunday). A weak surface low will meander over the Baja Peninsula
while surface high pressure will overspread the Rockies, as well as
the Upper MS Valley into the Great Lakes and northern Appalachians.
As such, the best chance for thunderstorms will be across portions
of the Interior West, where upper support with the mid-level trough
will lift a marginally buoyant airmass. Thunderstorms will also be
possible across the Florida Peninsula, up to the Carolina coastline,
where convective bands associated with Tropical Depression Nine
attempt to move ashore amid marginal instability. The chance of any
severe in these aforementioned areas is very low, so severe
probabilities are not currently warranted.
