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.

Rain in the past 24 hours for South Dakota

MRMS radar estimate · the past, not a forecast

Most anywhere in South Dakota: 0.1 to 0.25 in

MRMS estimates 0.1 to 0.25 in fell at the most, somewhere in the state in the 24 hours to 04:00Z.

The highest cell anywhere in the state, from its outline; not every point in it.

When: 16 Oct 04:00Z to 04:00Z: the 24 hours MRMS summed. Written 04:08Z.
Limits: Radar alone, not corrected to rain gauges: it can be too high or too low, most far from a radar, in mountains, and where hail or melting snow brightens the echo. It says nothing of what will fall, and is not a flood warning.

Forecast details

NOAA’s Multi-Radar Multi-Sensor system (MRMS) mosaics every radar into one estimate of the rain that fell, a grid about 1 km across, which this page samples every 0.05°, about 5 km. This is its radar-only estimate, written every hour. River Forecast Centers make a slower estimate corrected to rain gauges; this is not that. MRMS products.
