   ...Synopsis...
   The upper-level flow today across the CONUS will be predominantly
   northwesterly with a trough in the east and a ridge over the west. 
   At the surface, a strong high pressure system over the
   central/southern Plains will weaken as it shifts eastward across the
   Mississippi and Ohio Valleys.  As a result, the surface pressure
   gradient will weaken across the Southwest throughout the day.

   The pressure gradient across Southern California will peak in the
   morning and weaken rapidly after 18Z (10 a.m. local time). 
   Consequently, sustained offshore/downslope flow of 10-15 mph across
   portions of the Transverse and Peninsular Ranges will be limited to
   the morning hours.  Nevertheless, interior portions of Southern
   California will remain dry (minimum RH values of 8-15%), resulting
   in locally elevated fire weather conditions, especially for favored
   mountain/valley locations in Ventura and Los Angeles Counties.
