ACUS11 KWNS 070058 SWOMCD SPC MCD 070058 ARZ000-OKZ000-070200- Mesoscale Discussion 1011 NWS Storm Prediction Center Norman OK 0758 PM CDT Sat Jun 06 2026 Areas affected...lfar eastern Oklahoma and western Arkansas Concerning...Severe potential...Watch unlikely Valid 070058Z - 070200Z Probability of Watch Issuance...5 percent SUMMARY...Locally enhanced low-level shear could support sporadic damaging gusts or a brief tornado with a band of thunderstorms this evening. Broader organization is unlikely and a Watch is not expected. DISCUSSION...Early evening radar imagery showed a band of storms had developed near a remnant MCV across portions of far eastern OK and western AR. A very moist environment is in place with dewpoints in the 70s F. This is supporting low cloud bases and moderate buoyancy with MLCAPE of 1500-2000 J/kg. Locally backed low-level flow near the MCV is enhancing low-level shear with the SRX VAD showing 100-200 m2/s2 of ESRH. This is supporting weak storm-based rotation within the band of storms. While the lack of broader ascent and deep-layer shear should keep storm organization limited/transient, sporadic damaging gusts and a brief tornado are possible over the next couple of hours. Given the short duration and local risk, a WW is not expected. ..Lyons/Gleason.. 06/07/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LZK...SHV...TSA...
