How to read the Wallace County map
The colored swath is NOAA's MRMS radar estimate of the largest hail per ~1 km cell; the dots are SPC ground reports. Deep violet is about an inch, the violet grows lighter as the hail grows, and pale lilac to near-white is 2″ and up (hail size vs roof damage). On this county's worst day the reports reached 4.25 inches, which is the pale lilac band. Look up a street address with the hail history by address tool.
