Mesoscale Discussion 0494 NWS Storm Prediction Center Norman OK 1010 PM CDT Sat Apr 19 2025 Areas affected...portions of north Texas Concerning...Tornado Watch 149... Valid 200310Z - 200415Z The severe weather threat for Tornado Watch 149 continues. SUMMARY...The supercell tornado threat continues across southern parts of Tornado Watch 149. A brief, short-term uptick in tornado potential is possible with supercells merging with a baroclinic boundary. DISCUSSION...Three supercells are currently tracking northeastward across portions of north TX, west of the DFW metroplex. The Parker County supercell has a history of tornadoes, and tornado potential will continue with both of these storms over the next few hours. In the next 1-2 hours, these storms are poised to merge with a baroclinic boundary, which has encouraged other storms to merge into an MCS. With the boundary merger, a localized, brief uptick in tornado potential may be realized, and a strong tornado may occur. Thereafter, the storms will merge into the MCS and either become embedded supercells, or LEWPs/bowing segments, with some tornado threat persisting, though severe gusts will also be a concern. ..Squitieri.. 04/20/2025 ...Please see www.spc.noaa.gov for graphic product...
