   .PREV DISCUSSION... /ISSUED 0112 AM CST Tue Dec 11 2018/

   An active synoptic pattern will continue across the Lower 48 today,
   with stout mid-level disturbances centered over the northern/central
   Great Plains, Northeast, southern California, and the Pacific
   Northwest.  The Great Plains wave will induce cyclogenesis in
   northeastern New Mexico and vicinity, while Great Basin high
   pressure will assist in development of an offshore pressure gradient
   across southern California.  Although highlights have been withheld
   for this outlook, areas of locally elevated fire weather conditions
   will develop at times across the central Plains and along coastal
   ranges of southern California.

   ...Northeastern New Mexico northeastward into western Kansas...
   10-15 mph westerly downslope flow will develop in vicinity of the
   deepening surface low and west of a front/wind shift from the
   Panhandles into central Kansas.  Minimum RH values will fall to
   around 20-35% west of the wind shift, and fuels are not expected to
   support large fires on a widespread basis.  Nevertheless, where
   finer fuels are cured, locally elevated fire weather will develop
   for a couple of hours during peak heating.

   ...Southern California...
   Gusty offshore flow will develop throughout the day in response to
   the aforementioned pressure gradient.  Minimum RH values should only
   fall to around 20-30% however, and fuels are not cured on a
   widespread basis owing to recent rainfall across the area.  Locally
   elevated fire weather conditions can be expected where fine fuels
   are dry.
