Mesoscale Discussion 2124 NWS Storm Prediction Center Norman OK 0340 PM CDT Tue Sep 23 2025 Areas affected...Portions of North Texas Concerning...Severe potential...Watch possible Valid 232040Z - 232245Z Probability of Watch Issuance...40 percent SUMMARY...Large hail and severe gusts will be possible in parts of North Texas. A watch is not currently anticipated, but convective trends will be monitored for the possibility of a watch. DISCUSSION...South of the upper-level trough, forcing for ascent is weak. Even so, strong heating (temperatures near 100 F) have promoted deepening cumulus within a prefrontal confluence band as well as near a weak cold front/surface trough farther west. Given observational trends, it appears probable that a few storms are possible this afternoon. Coverage over the next two hours is not certain. It may take the front moving southward to provide enough lift for additional storms. A very moist airmass (upper 60s to low 70s dewpoints), moderately steep mid-level lapse rates sampled by the 12Z FWD sounding and recent TAMDAR soundings, and around 30 kts of effective shear suggests large hail would be possible. Severe gusts could also occur given steep low-level lapse rates. Limited coverage of storms may ultimately preclude a watch, but convective trends near the DFW metro will be monitored into the evening. ..Wendt/Smith.. 09/23/2025 ...Please see www.spc.noaa.gov for graphic product...
