...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Scattered thunderstorms are possible from the Gulf Coast states to the Carolinas, and across the northern Plains/Upper Midwest. Severe thunderstorm potential appears limited at this time.


...Synopsis...


Broad upper troughing will envelop much of the CONUS east of the Rockies on Monday. Modest deepening of the trough will result in a belt of increasing northwesterly flow aloft from the northern High Plains into the Mid-South. At the surface, a cold front will extend from the southern Mid-Atlantic coast west/southwest across the Gulf Coast states into central TX. This boundary will sag southward through the period. Rich boundary layer moisture will be in place ahead of the boundary, but this region will remain displaced to the south of strong mid/upper level flow. Scattered thunderstorms are possible, and some gusty winds could occur. However, organized severe potential appears limited.  

Further north across the northern Plains/Upper Midwest, scant boundary layer moisture is forecast. Weak destabilization is possible via cooling aloft/steepening lapse rates. This could be sufficient for isolated, higher-based thunderstorms. Gusty winds and maybe small hail could occur, but overall severe potential appears low.
