Additional development will be possible near and north of the warm front. A Tornado Watch will likely be needed downstream of WW144. DISCUSSION...A pair of supercells have developed across Le Flore County in OK and will track eastward into Arkansas. It is possible that additional development will be possible along and north of the warm front across central Oklahoma into western Arkansas. The environment across this region is very favorable for supercell maintenance, with MLCAPE around 1500-3000 J/kg. VAD profiles from KSRX shows an elongated hodograph with some low-level clock-wise curvature. Given the location of current development north of the warm front, the primary risk will likely be for elevated storms with potential for large to very large hail (some 2-3+ inches in diameter). Should a storm track further south near the warm front and become surface based, potential for a tornado or two will increase. A Tornado Watch will be needed soon. ..Thornton/Leitman.. 04/25/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LZK...SHV...TSA...
