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.
