SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1059 AM CST Thu Jan 15 2026 Valid 161200Z - 171200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not forecast across the contiguous United States on Friday. ...Discussion... Embedded within a large-scale trough encompassing the eastern two-thirds of the CONUS, a shortwave trough will overspread the mid-Mississippi Valley into the lower Great Lakes during the afternoon. Strengthening large-scale ascent and steepening of deep-layer lapse rates may yield weak and shallow buoyancy. However, thermodynamic profiles appear insufficient to support deep convection or lightning at this time. ..Weinman.. 01/15/2026
