SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1048 AM CST Sat Jan 31 2026 Valid 011200Z - 021200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm potential appears low on Sunday. ...Synopsis... A large and powerful cyclone initially offshore of the Carolina coast will move northeastward over the western Atlantic on Sunday, with cold, dry, and stable conditions expected in its wake across the eastern CONUS. Elsewhere, a low-amplitude midlevel shortwave trough will move across the Pacific Northwest early in the period. Cold temperatures aloft and very weak buoyancy will accompany this system, and very isolated/sporadic lightning flashes cannot be ruled out, but it currently appears that convection will be too weak/shallow for a more substantial thunderstorm threat. ..Dean.. 01/31/2026
