Mesoscale Discussion 0384 NWS Storm Prediction Center Norman OK 0249 PM CDT Mon Apr 08 2024 Areas affected...eastern portions of central Texas into adjacent western Louisiana Concerning...Tornado Watch 90... Valid 081949Z - 082145Z The severe weather threat for Tornado Watch 90 continues. SUMMARY...The risk for severe hail, and perhaps a couple of tornadoes, may continue to increase with a couple of evolving supercells, before thunderstorms possibly begin consolidating into an organizing cluster near and north of the College Station and Huntsville into Lufkin vicinities toward 5-6 PM CDT. DISCUSSION...Thunderstorms have increased in coverage and intensity within a narrow corridor, which likely coincides with the northern/leading edge of stronger mid-level inhibition, beneath building ridging within the subtropical branch of westerlies. Models suggest that one on two speed maxima within this regime will contribute to strengthening upper divergence along this corridor during the next few hours, supporting potential for considerable further upscale convective growth. A couple of supercells which have recently evolved to the southeast of the College Station and Huntsville vicinities may continue to intensify in the near term, aided by increasing inflow of moist boundary-layer air characterized moderately large CAPE, in the presence of strengthening shear. Gradually, though, it appears that forcing associated with lower/mid-tropospheric warm advection may tend to become focused to the north of College Station and Huntsville into Lufkin vicinity, where strongest storms may evolve into an increasingly organized cluster by 22-23Z. ..Kerr.. 04/08/2024 ...Please see www.spc.noaa.gov for graphic product...
