...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast through tonight across the
contiguous United States.
...Northwest Gulf Coast into the Ark-La-Miss...
The low-level airmass over this region is continuing to slowly
modify after a previous arctic intrusion into the Gulf basin. Only
limited diurnal destabilization (i.e., mainly 50s surface dewpoints
yielding weak CAPE) is expected within a warm conveyor extending
across the central Gulf Coast states eastward into the southern
Appalachians. A mid-level trough will approach the region and aid
in pushing a cold front southeast. Forecast soundings suggest weak,
isolated thunderstorms are possible this afternoon over east TX and
the Ark-La-Tex before shifting east-southeast across the lower MS
Valley later this evening into tonight.
