SPC 0600Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1242 AM CDT Thu Oct 30 2025 Valid 311200Z - 011200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm potential appears low on Friday. ...Synopsis... A strong mid/upper-level shortwave trough and embedded midlevel cyclone will move northeastward across New England on Friday, in conjunction with a deep surface low. Stable conditions in the wake of this system and its attendant cold front will limit thunderstorm potential through the period. Weak elevated convection may accompany the midlevel cyclone across northern New England early in the day, but buoyancy appears too weak/shallow for more than very isolated/sporadic lightning flashes. Farther west, a mid/upper-level trough will dig southeastward across the Great Plains and upper MS Valley. Cold temperatures aloft associated with this trough could support weak convection across parts of the Upper Midwest and Great Lakes, but this convection is generally expected to remain too shallow for thunderstorm development. Weak low-level moisture return may commence near the TX Gulf Coast by early Saturday morning, but forecast buoyancy is very weak to negligible through the end of the period. ..Dean.. 10/30/2025
