The lightning images below are updated daily around 7:30–8:30 AM and contain 24-h accumulations of lightning ending at 6 am MDT (5 am MST) each day. There are two sets of images for (1) NLDN cloud-to-ground flashes only and (2) GOES-East Lightning Mapper (GLM) cloud flash points. Option #1 only represents cloud-to-ground lightning flashes, and is based on a surface detection network. Option #2 does not discriminate between cloud-to-ground versus in-cloud flashes (i.e., it represents the total lightning) and is based on satellite. In-cloud lightning flashes can comprise 60–90% of the total lightning (i.e., most lightning does not reach the ground). Satellite-based lightning detection also does not depict the exact location where the flash occurred because of an issue known as "parallax." Mouse over each day to view the 24-h cumulative lightning flash maps. Printable versions are at the bottom of each of the three map segments.
