MESH Drastically Underestimates a Right Mover while HSDA is Right on Target

Posted in Live Blogs on by Greg Stumpf.

A storm producing reported 2.75 inch hail was estimated by the MRMS MESH product to be dropping only 1 inch hail. This storm was moving right as it continued to develop.

The HSDA algorithm did a good job of keeping a large to giant hail tag on this storm as it became severe and maintained its intensity.
