How to read the North Dakota map

The colored swath is NOAA's MRMS radar estimate of the largest hail in each ~1 km cell; the dots are individual SPC ground reports. Yellow is around an inch, red is 1.5 to 2″, and purple is 2″ and up -- see how hail size maps to roof damage. Click any spot on the map to see the hail history at that point, or look up a full street address on the hail history by address tool. Today's nationwide activity is on today's hail report.
