The previous forecast remains on track with only minor adjustments needed based on trends in recent high-res guidance. Solutions continue to suggest the onset of critical fire weather conditions between 20-00 UTC along the southern CA coast. Windier solutions, notably the HRRR, suggest widespread sustained winds between 25-35 mph are possible during the overnight hours with some locations seeing RH reductions to near 10%, and possibly into the upper single digits. Consequently, high-end critical fire weather conditions are possible by the end of the period (early Wednesday morning). ..Moore.. 01/06/2025 .PREV DISCUSSION... /ISSUED 0132 AM CST Mon Jan 06 2025/ ...Synopsis... An upper-level trough is expected to strengthen within the Great Basin/lower Colorado River Valley on Tuesday. This trough will eventually evolve into a cutoff low centered over the lower Colorado River Valley overnight Tuesday into Wednesday morning. At the surface, a strong surface high will build into the Great Basin, extending even into the Plains. ...Southern California... The combination of an intensifying offshore pressure gradient and strong upper-level wind support will promote elevated to critical fire weather across much of southern California. The strongest winds will occur within the typical Santa Ana wind corridors. Winds of at least 20-25 mph will be possible, with stronger winds within the terrain. Current model guidance suggests the strongest wind gusts will be during the evening when mid-level jet core will be overhead. RH during Tuesday afternoon could fall to 10-20%. Some overnight RH recovery is possible, but strong winds should continue to support fire weather concerns into Wednesday morning. ...Please see www.spc.noaa.gov/fire for graphic product... $$
