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.

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected Sunday.

...Synopsis...
A front will stall in the vicinity of south FL and provide a focus
for thunderstorm development in a moist environment with PW values
in excess of 2 inches.  Across AZ/NM, a midlevel trough will eject
northeastward in advance of height falls over the Pacific Northwest
coast late in the period.  Midlevel lapse rates, moisture and ascent
could be sufficiently deep for charge separation and isolated
lightning flashes with weak midlevel convection.

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.
