An upper-level trough will dig southeastward across the Rockies and close-off in the western part of the southern plains during the day 3 period. This will spread strong ascent across the region favorable for widespread thunderstorm development during the day. In response to the upper-trough...a low-level jet will organize Saturday across the northern Gulf of Mexico spreading abundant moisture into the gulf coastal states. Sfc dewpoints of 65 to 70 f will aid destabilization with moderate instability likely from east TX extending eastward to southern Mississippi Saturday afternoon. Forecast soundings show strong vertical shear across the region which suggests an environment favorable for supercells. Backed low-level winds...strong 850 mb and steep mid-level lapse rates will increase the potential for tornadoes...large hail and wind damage as a large cluster of storms develops Saturday afternoon in east Texas/western Louisiana and spreads eastward into southern Mississippi. Portions of the outlook may need to be upgraded to a moderate risk in later outlooks.
