Valid 081200Z - 091200Z

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

....SUMMARY...
Severe thunderstorms are not forecast on Sunday.

....Synopsis and Discussion...
An upper trough should progress eastward from the MS Valley across
the eastern CONUS on Sunday. A weak surface low is forecast to
translate from the TN Valley towards the Mid-Atlantic through the
period. Low-level moisture return ahead of a southeastward-moving
cold front will likely remain limited across coastal TX into the
lower MS Valley and Southeast. Corresponding instability should also
be quite weak, with low potential for robust convection over land.
Still, general thunderstorms will probably be ongoing Sunday morning
in a modest low-level warm advection regime across parts of coastal
TX into the lower MS Valley along/near the cold front. This activity
should generally move offshore through the day. Isolated
thunderstorms may also occur over portions of CA, mainly Sunday
morning. This low-topped convection will largely be aided by strong
ascent and cool mid-level temperatures associated with another
shortwave trough moving quickly eastward over the western states.
