6AM Day 1 Convective Outlook for Tuesday, February 3. 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.
