821 ACUS11 KWNS 270127 SWOMCD SPC MCD 270127 OKZ000-TXZ000-270300- Mesoscale Discussion 1441 NWS Storm Prediction Center Norman OK 0827 PM CDT Wed Jun 26 2024 Areas affected...Portions of North Texas Concerning...Severe Thunderstorm Watch 470... Valid 270127Z - 270300Z The severe weather threat for Severe Thunderstorm Watch 470 continues. SUMMARY...Large hail and severe winds remain possible with a supercell in North Texas. Southern extent of the threat is not clear. Watch extensions will need to be considered if trends warrant. DISCUSSION...A supercell near Denison/Sherman has generally been moving south-southwestward roughly along an outflow boundary. This storm will likely continue into the mid evening. So far, 1 inch hail has been reported with this storm. MLCIN has been increasing to the south over the last hour. However, with an established supercell, it will take time to have a negative impact on the storm. The outflow boundary drapes southward trough western portions of the Metroplex. The observed 00Z FWD showed modest MLCIN along with steep mid-level lapse rates and 34 kts of effective shear. It is not clear whether this storm will persist far enough to impact DFW proper, but it is possible. Trends will need to be monitored for possible watch extensions farther south. ..Wendt.. 06/27/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...FWD...OUN...
