Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0744 PM CDT Sun Oct 18 2026
Valid 190100Z - 191200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast across the U.S. through
tonight.
...DISCUSSION...
An upper-level ridge will move eastward into the southern
Appalachians tonight, as southwesterly flow at mid-levels remains in
place across much of the western and central U.S. At the surface, a
large area of high pressure will remain entrenched from the Gulf
Coast states to the Northeast. As a result, dry and cool conditions
will remain over much of the continental U.S. Isolated thunderstorms
will be possible over south Florida and in parts of the Desert
Southwest, but no severe threat is forecast this evening through
tonight.
