SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0800 PM CDT Thu Jul 27 2023 Valid 280100Z - 281200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM WISCONSIN INTO CENTRAL AND SOUTHERN MINNESOTA... ...SUMMARY... Scattered severe storms capable of wind damage or hail remain possible mainly from central Wisconsin into southern Minnesota. Isolated hail is possible over parts of South Dakota this evening. ...MN into WI... A large complex of storms current stretches across much of northern WI and back into central MN. Substantial outflow has been produced by these storms clusters, with embedded stronger bows at times. 00Z soundings from MPX and GRB indicate MLCAPE of 2000-3000 J/kg along with steep midlevel lapse rates, and moderate mid to high level flow. However, winds in the low levels are generally below 20 kt at this time. Given the amount of outflow and the unstable air mass to the south, a continued threat of sporadic damaging wind and hail will remain for several more hours. For more information see mesoscale discussion 1744. Elsewhere, several cells have increased in intensity over central SD, and these may interact with moisture to the east and yield sporadic hail. ..Jewell.. 07/28/2023
