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.

Checked means retrieved, not newly issued. Each graphic retains its issue, observation, initialization or valid time. Site publishing status is separate.

Potential too low: SPC expects too little severe weather to outline a 15% area. Predictability too low: the forecasts differ too much to place an area; severe storms are not ruled out. Neither means no hazardous weather.

Hazard & forecast product

...DISCUSSION...
A rather stagnant upper-air pattern will be in place across the
CONUS into early next week, with an upper ridge continuing over the
central U.S. as a mid-level cut-off low meanders along the Atlantic
coastline and an upper trough gradually amplifies along the West
Coast. By the middle to end of next week, the West Coast upper
trough will advance eastward toward the Rockies, encouraging surface
lee troughing and subsequent low-level moisture return (albeit
modest) across the Great Plains states. Thunderstorm development is
possible, especially across portions of the southern High Plains
Days 6-7 (next Wednesday-Thursday). However, deterministic guidance
suggests that little overlap of meaningful buoyancy and vertical
wind shear will take place over the southern High Plains next
Wednesday-Thursday, with calibrated ML/AI guidance only hinting at a
severe threat that will be isolated at best. Therefore, severe
probabilities have been withheld this outlook.

Forecast details

SPC’s Days 4–8 outlook outlines where it sees at least a 15% or a 30% chance of severe thunderstorms within 25 miles of a point on each day. It has no categories and no hazard of its own. “Potential too low” means SPC expects too little severe weather to outline 15%; “Predictability too low” means the forecasts differ too much to place an area, and severe storms are not ruled out. A day further out is less certain than Days 1–3. SPC’s Days 4–8 page.
