Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1125 PM CST Fri Jan 30 2026
Valid 311200Z - 011200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not forecast across the U.S. today through
tonight.
...Synopsis...
Long-wave troughing will persist across the eastern CONUS as an
embedded shortwave trough steadily intensifies off the East Coast.
Isolated to scattered thunderstorms are likely off the GA/Carolina
coast as an attendant surface cyclone intensifies; however, the warm
sector of the low will remain well offshore, precluding the
potential for thunderstorms over land. Elsewhere, seasonally cool
conditions across the central CONUS and upper ridging over the West
will further nullify thunderstorm development.
