   Valid 281200Z - 291200Z
   
   The previous forecast remains on track for southern California, with
   no changes made. Locally Elevated conditions are possible across
   portions of the southern Great Basin, with 15 mph sustained
   north-northeasterly surface winds overlapping critically low RH and
   receptive fuels. However, given overall cooler temperatures
   expected, along with a weaker surface flow field compared to
   previous days, an Elevated area has been withheld this outlook.

   ...Synopsis...
   Although many areas in the West (particularly California, Nevada,
   and Arizona) will remain very dry, surface winds will slacken in
   many areas as Great Basin high pressure weakens and shifts to the
   east of that region.  Additionally, mid/upper flow will slacken as
   an evolving cutoff low moves away toward the southern High Plains. 
   Enough surface flow will remain across coastal ranges of southern
   California to introduce highlights for elevated fire weather in that
   area.  Elsewhere, a cold and unsettled pattern (particularly across
   the southern Plains/Rockies) will keep any fire-weather concerns at
   a minimum.
   
   ...Southern California...
   Recent high-resolution guidance indicates that areas of 15-25 mph
   surface flow will linger especially in terrain-favored areas of the
   coastal ranges through the forecast period.  The offshore nature of
   the flow will maintain dry low-level conditions (5-15% RH).  Areas
   of dry fuels remain given the antecedent dry conditions through much
   of summer.  These conditions merit an elevated fire-weather
   delineation.
