Lightning ignition potential is lower across Arizona and New Mexico where deeper moisture profiles will promote more wetting rain cores. ..Williams.. 07/16/2025 .PREV DISCUSSION... /ISSUED 0142 AM CDT Wed Jul 16 2025/ ...Synopsis... Moisture will increase on D2/Thursday across the Southwest with a cut off low off the coast of Baja California.

As such, a broad area of isolated dry thunderstorms was maintained with this outlook. ...Please see www.spc.noaa.gov/fire for graphic product... $$
