Day 1 Fire Weather Outlook

0111 AM CDT Sat Jun 13 2026

Valid 131200Z - 141200Z

...Synopsis...
Isolated dry thunderstorms are forecast from the Four Corners region into parts of the Great Basin during the afternoon as deep boundary layer mixing with meager moisture content results in deep inverted-V profiles across the area. Precipitable water content of 0.5-0.75 in and tall LCLs exceeding 3.5 km will significantly reduce precipitation efficiency, and with ERCs in the 90th-98th percentile ranges, lightning ignitions will be a concern. Precipitable water content increases to 1.0-1.25 in with southward extent, suggesting the dividing line between wet/dry thunderstorms will be somewhere in the central portions of Arizona and New Mexico. While the exact details of where the dry-to-wet thunderstorm transition will set up remains unclear, some lightning ignitions may be supported on the periphery of more precipitation efficient downdrafts as well.
