ZCZC SPCSWOMCD ALL ACUS11 KWNS 261235 SPC MCD 261235 ARZ000-MOZ000-OKZ000-261430- Mesoscale Discussion 0524 NWS Storm Prediction Center Norman OK 0735 AM CDT Fri Apr 26 2024 Areas affected...Eastern OK to southwest MO/western AR Concerning...Tornado Watch 138... Valid 261235Z - 261430Z The severe weather threat for Tornado Watch 138 continues. SUMMARY...Severe thunderstorms including the potential for primarily damaging winds and a couple tornadoes continues across eastern Oklahoma, and may develop into far western Arkansas and possibly southwest Missouri. Tornado Watch 138 continues for eastern Oklahoma, and downstream Arkansas/southwest Missouri areas are being monitored for possible but uncertain Watch issuance in the short term. DISCUSSION...A well-organized squall line with LEWP/northern-peripheral bowing characteristics continues across eastern Oklahoma, with bow-related northeastward storm motions around 50 kt. The most intense portion of the squall line and greatest short-term severe risk should be focused where the convective line intercepts the warm front (and just a bit north thereof) in the general vicinity of I-40 in far eastern Oklahoma into west/northwest Arkansas. Farther north, the severe-potential longevity of the surging bowing portion of the line is a bit more uncertain with northward extent, given that the bowing line will gradually encounter an increasingly more stable boundary layer (0.5 km AGL deep per 12z Springfield MO observed sounding). ..Guyer.. 04/26/2024 ...Please see www.spc.noaa.gov for graphic product...
