   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHERN CALIFORNIA...

   ...Synopsis...
   A broad trough across the West will undergo intensification today. A
   strong mid-level jet will develop in the western Great Basin and
   California. At the surface, high pressure will strengthen in the
   Great Basin into the lower Colorado River Valley.

   ...Southern California...
   The offshore pressure gradient may be sufficient to support elevated
   to critical fire weather by this afternoon. RH will be the main
   uncertainty during the afternoon, but around 20% appears likely and
   near 15% is certainly possible. Winds this afternoon will peak at
   20-25 mph outside of the terrain. Both the offshore gradient and the
   supporting upper-level winds are expected to increase in magnitude
   during the evening/overnight into Wednesday morning. The strongest
   upper-level winds (and thus wind gusts) are most likely around very
   late today to early Wednesday. How low RH will remain overnight is
   also somewhat uncertain, but wind strength (25-35 mph) would still
   support higher-end critical conditions in the typical Santa Ana
   corridors in LA/Ventura Counties.
