Critical to extremely critical fire-weather conditions will be ongoing across southern CA at the start of the Day 3/Tuesday period, as the offshore pressure gradient will be at peak magnitudes (LAX-DAG gradient around -8 to -10 mb). This gradient, coupled with continued upper-level support through at least 15Z, will result in very strong/gusty northeasterly surface winds and single-digit RH across much of southern CA. The strongest winds should remain focused over the wind-prone Santa Ana corridor of northern/western Los Angeles County into eastern Ventura County -- where the greatest risk of Extremely Critical conditions will persist through at least 15Z. Thereafter, the positive-tilt shortwave trough and strong winds aloft that were providing upper-level support for the strong Santa Ana event on Day 3/Tuesday will continue east-southeastward into the central CONUS. However, strong surface high pressure will persist across the Intermountain West, favoring continued dry offshore flow across southern CA on Day 4/Wednesday through Day 5/Thursday. Current indications are that the offshore pressure gradient will yield elevated to locally critical fire-weather conditions both days/mornings, though the lack of upper-level support limits confidence in any more than locally critical conditions -- precluding 70-percent probabilities at this time. ..Weinman.. 01/19/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
