Day 2 Convective Outlook  

NWS Storm Prediction Center Norman OK

1245 AM CDT Sat Oct 17 2026



Valid 181200Z - 191200Z



...NO SEVERE THUNDERSTORM AREAS FORECAST...



...SUMMARY...

Severe thunderstorms are not expected tomorrow (Sunday).



...Synopsis...

A mid-level ridge will remain over the central U.S. while a 500 mb

cut-off low meanders off of the Atlantic Coast and broad upper

troughing dominates the western CONUS tomorrow (Sunday). A

relatively cool and stable low-level airmass will overspread much of

the CONUS, inhibiting thunderstorm development. A few thunderstorms

may occur over the southern FL Peninsula, where the heating of

remnant low-level moisture will promote localized lift and buoyancy.

A couple of lightning flashes may also occur over portions of the

Desert Southwest, where cooler temperatures aloft and modest ascent

will accompany a weak mid-level impulse.
