Convective/observational trends will continue to be monitored for a possible watch this afternoon. DISCUSSION...Storms have recently initiated along a pre-frontal confluence zone in Northeast Texas. Based on the observed 12Z Shreveport, LA sounding as well as the character of boundary layer clouds on visible satellite, there is still inhibition left to overcome this morning. That said, objective mesoanalysis shows more minimal amounts of MLCIN remaining right along the confluence zone. Activity may initially struggle to intensify until greater surface heating occurs through the day. Strong effective shear is in place, though it is largely parallel to confluence zone and cold front that lags to the northwest. 2000-2500 J/kg MLCAPE and steep mid-level lapse rates will eventually support rapid storm intensification. Large/very-large hail and severe gusts would be possible. The tornado threat will depend on the overall storm mode, which could lean linear, but strong low-level shear apparent on regional VAD data and a very moist airmass (mid/upper 60s F dewpoints) would favor potential for tornadoes, some of which could be strong. Timing of storm intensification is uncertain given the inhibition and overall lack of a stronger/focused forcing mechanism. Convective/observational trends will be monitored for a possible watch this afternoon. ..Wendt/Guyer.. 04/02/2025 ATTN...WFO...SHV...FWD...
