A mesoscale discussion is the Storm Prediction Center’s note on an area it is watching, which may or may not lead to a watch. A discussion reaches a state when SPC’s outline does.

About this data
Not an official warning service. Warnings and watches are drawn from the National Weather Service, and discussions, outlooks and reports from its Storm Prediction Center (Data: NOAA/NWS, NOAA/SPC). When a warning is issued for you, act on it — and use weather.gov or a NOAA Weather Radio for where you are.
Radar: NOAA MRMS mosaic via nowCOAST, drawn live with no last-good copy: an empty radar means we cannot see, not that the sky is clear. Warnings and watches: NOAA/NWS. Discussions, outlook and reports: NOAA/SPC. The maps are ours; the warnings are theirs.
