A storm tracking across the Southern U.S. will bring heavy to excessive rainfall over portions of west-central Texas into tonight then from central Texas through the central Gulf Coast on Friday. The Southeast U.S. will see heavier rain Saturday. While much of this rainfall will be beneficial to the drought, excessive rainfall may bring areas of flash and urban flooding. Read More >
The lightning images below are updated daily around 7:30 to 8:30 AM and contain 24-hr 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.
