Subj : DAY2SVR: Nws Storm Prediction Center Norman Ok To : All From : Mike Powell Date : Sat May 23 2026 09:15:46 ACUS02 KWNS 230555 SWODY2 SPC AC 230553 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1253 AM CDT Sat May 23 2026 Valid 241200Z - 251200Z ....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM CENTRAL NEBRASKA INTO SOUTHWEST MINNESOTA... ....SUMMARY... Widely scattered thunderstorm activity will be possible from the southern/central Plains to the southeastern US into the lower Ohio Valley. A few stronger storms may be possible from central Nebraska into southwest Minnesota. ....Synopsis... Widely scattered afternoon thunderstorms are likely south of a stationary front extending from the southern Plains into the lower Ohio Valley. A few additional thunderstorms will be possible across the southern High Plains within the easterly upslope regime. A weak shortwave trough will move across the central/northern Plains into the Upper Midwest on D2/Sunday, which may be a focus of thunderstorm development across portions of Nebraska into Minnesota. Large hail and damaging wind will be the primary threat with these storms. ....Nebraska into Minnesota... A plume of mid 50s to 60s dew points will advect northward into portions of eastern Nebraska into southern Minnesota Sunday afternoon amid increasing southerly flow across the central/northern Plains. A weak shortwave will move eastward across this area with thunderstorm development likely by the afternoon. Forecast soundings suggest that deep layer shear will be sufficient to support supercells, with around 40 kts in the 0-6 km layer. In addition to the increase in moisture, steep low to mid-level lapse rates will also overspread the area. This, in combination with strong deep layer shear, will favor potential for large hail (isolated very large hail up to 2" in diameter). Well mixed profiles may also support a few instances of strong to severe wind. ...Thornton.. 05/23/2026 $$ --- MultiMail/DOS * Origin: ILink: Project Scorpio TEST (454:1/105.6) .
