Valid 241200Z - 251200Z

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

....SUMMARY...
Severe thunderstorms are not forecast today or tonight across the
contiguous United States.

....Synopsis...
A mid- to upper-level trough initially over the High Plains will
feature a shortwave trough pivoting east through the base of the
larger-scale trough and reaching the lower MS Valley tonight.  As
this process occurs, an upstream disturbance over the north-central
Rockies will dig south-southeast into CO/NM during the day before
evolving into a closed mid-level low centered over the central High
Plains early Monday morning.  In the low levels, a cold front over
the southern Great Plains will sweep southeastward across OK and the
eastern half of TX as a cyclone moves east paralleling the OK/KS
border before moving into the lower MO Valley by daybreak Monday.
Showers and isolated to widely scattered thunderstorms will likely
be ongoing across the eastern halves of OK/TX into LA during the
morning.  Considerable cloud cover will likely limit destabilization
during the day across the northwest Gulf Coast.  Although a strong
storm or two cannot be ruled out, it seems likely that general
thunderstorm activity will prevail over the south-central U.S.
through tonight.
