Mesoscale Discussion 0963 NWS Storm Prediction Center Norman OK 1016 PM CDT Sat May 25 2024 Areas affected...Far North-Central TX Concerning...Tornado Watch 308... Valid 260316Z - 260415Z The severe weather threat for Tornado Watch 308 continues. SUMMARY...An intense supercell capable of producing a strong tornado is expected to continue for at least the next hour over far north-central Texas. DISCUSSION...Recent radar imagery has shown an notable increase in intensity of the supercell over Montague and Cooke County in far north-central Texas. Echo tops now over 60 kft, with a very strong low-level circulation observed as well. Recent mesoanalysis estimates that effective helicity is over 800 m2/s2 and effective shear is over 70 kt near this supercell. This intense shear coupled with very strong buoyancy (i.e. 4500 J/kg) is resulting in STP values from 16 to 18. Given the supercellular mode, a strong tornado is possible within this environment. An extension in time for Tornado Watch 308 may be needed. ..Mosier.. 05/26/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...FWD...OUN...
