Each feed is judged on its own clock. The masthead’s reading is the site’s publishing health, which is a different thing: a publishing delay does not make a freshly read warning stale, and a fresh check does not make an old outlook newly issued.

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.

Forecast details

SPC’s categorical outlook rates the coverage and intensity of organized severe storms on five levels, from Marginal (1) to High (5); “Thunderstorms” outlines a 10% or greater chance of thunderstorms and is not a severe category. Each probability is the chance of that hazard within 25 miles of a point during the valid period. An intensity overlay marks where significant severe hazards are more likely should storms occur. An outlook is a forecast; a warning means a storm is happening or imminent. SPC’s definitions.
