   ...Synopsis...
   Tomorrow (Saturday), a high-amplitude mid-level trough associated
   with a cold airmass is forecast to overspread much of the central
   and eastern US. This trough will be accompanied by a strong jet
   maximum moving southward across the Intermountain West, which will
   bring dry and windy conditions to portions of Arizona and New
   Mexico. However, with generally cooler temperatures and a lack of
   receptive fuels, any fire-weather threat should remain localized.

   Day 3-8 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   0359 PM CST Fri Jan 17 2025

   Valid 191200Z - 251200Z

   ...Southern California...
   Within the base of a highly amplified, positive-tilt large-scale
   trough over the West, an embedded shortwave trough will track
   southeastward across the Southwest into the southern Rockies from
   Day 4/Monday into Day 5/Tuesday. At the same time, an amplified
   upper ridge will build over the eastern Pacific, favoring
   strengthening surface high pressure over the Intermountain West.
   This pattern will result in a strengthening offshore pressure
   gradient across southern CA (-6 to -8 mb LAX-DAG gradient), with
   moderate midlevel support across the area. Given reasonably good
   agreement in the development of single-digit to lower teens RH and
   strong/gusty east-northeasterly surface winds, 70-percent Critical
   probabilities have been introduced for the wind-prone Santa Ana
   corridor (much of Ventura County, northern/western Los Angeles
   County, and portions of northern San Bernardino County) for Day
   4/Monday into Day 5/Tuesday. 

   From Day 6/Wednesday into Day 7/Thursday, another shortwave trough
   should track southeastward across the Great Basin and Southwest,
   while an upstream ridge builds over the eastern Pacific. While
   noteworthy differences are evident among the medium-range guidance
   regarding this overall evolution, current indications are that
   surface high pressure will once again strengthen over the
   Intermountain West, favoring the potential for another dry offshore
   wind event across southern CA. 40-percent Critical probabilities
   have been added for Day 6/Wednesday into Day 7/Thursday, and higher
   probabilities could eventually be needed as the details become more
   clear.
