   The offshore pressure gradient currently in place across coastal
   ranges of southern California should weaken with time throughout the
   day (D2/Thursday), with only localized/terrain-favored areas
   experiencing strong gusts.  Warm temperatures and critically low RH
   values will continue throughout the forecast period, resulting in
   elevated to locally critical fire weather conditions.

   See the previous discussion below for more information.

   An upper-level ridge will break down during the Day 2 period, with
   weak flow aloft accompanying a west-northwesterly flow regime. At
   the surface, an inverted thermal trough and corresponding modest
   pressure gradient will persist across California throughout the

   ...Southern California...
   The aforementioned pressure gradient is expected to be somewhat
   weaker compared to previous days. 15-20 mph sustained
   east-northeasterly offshore winds, critically low RH, and very dry
   fuels are expected to be present across much of southwest
   California, particularly during the morning hours, warranting an
   elevated delineation. Locally critical conditions (20-30 mph
   sustained winds) are possible, mainly within terrain-favoring
   areas/higher terrain of the southern California Foothills. Given the
   brevity and locally constrained nature of the 20-30 mph winds, a
   critical delineation will not be issued at this time, though trends
   will continue to be monitored for the potential of more widespread
   critical surface conditions.
