SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0149 AM CDT Wed Oct 29 2025 Valid 311200Z - 011200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm potential appears low on Friday. ...Synopsis... A broad, large-scale mid/upper-level trough will remain in place over much of the central/eastern CONUS on Friday. Within the large-scale trough, a mid/upper-level cyclone and attendant deep surface low will move northeastward across New England, as an upstream trough amplifies across parts of the Plains and Upper Midwest. Dry/stable conditions in the wake of a significant frontal passage will limit thunderstorm potential across the CONUS. Weak convection will be possible across parts of northern New England and also across the Great Lakes vicinity, but forecast buoyancy appears insufficient for more than very isolated/sporadic lightning activity. Some low-level moisture return may commence across parts of south TX Friday night, but instability is expected remain negligible through the end of the period. ..Dean.. 10/29/2025
