MD 0546 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR NORTHEAST TEXAS AND NORTHWEST LOUISIANA Mesoscale Discussion 0546 NWS Storm Prediction Center Norman OK 0803 AM CDT Sun Apr 26 2026 Areas affected...Northeast Texas and northwest Louisiana Concerning...Severe potential...Watch unlikely Valid 261303Z - 261430Z Probability of Watch Issuance...20 percent SUMMARY...Elevated storms could continue to produce isolated large hail this morning, but storm coverage is in question and a watch appears unlikely. DISCUSSION...Elevated storms have persisted overnight in small clusters, aided by warm advection along an outflow/baroclinic zone. A couple of storms have developed supercell structures, with isolated 2-3 inch hail earlier in north TX. Isolated large hail may occur with newer storm development into northwest LA, where profiles display enough vertical shear for storm organization. The coverage and persistence of storms through the morning is not clear, as is the need for a watch. ..Thompson/Gleason.. 04/26/2026 ...Please see www.spc.noaa.gov for graphic product...
