.KEY MESSAGES...

  dry conditions.
* A warming trend arrives Tuesday into at least Thursday, with dry
  weather.
* There is the chance for another system by the end of next week,
  but confidence in the details remains low.

.DISCUSSION...
Today will be another cool, fall-like day, with light easterly
breezes giving way to afternoon gusts around 15 mph. Tonight, Sierra
valleys will realize overnight lows that once again dip below
freezing. This cool weather pattern is about to shift slightly
to a warmer trend this week.
Starting Tuesday, we see a minor ridge develop over the west, which
will bring about a warmer airmass to the region. By Wednesday,
leeside valleys will see high temperatures well into the mid to
upper 70s, with areas such as Hawthorne flirting with the low 80s.
This pattern is short-lived, and after midweek the guidance becomes
clear as mud.
For late week, guidance is resolving a low dropping along the
Pacific coast. Beyond that, there is little agreement as of now
regarding the depth of the trough, the placement of the center of
circulation and it`s trajectory. This lets us know there is
*something* out there, but the timing, placement and trajectory are
all in question. For the time being, NBM blended guidance hints at a
wetter pattern emerging, but there is discrepancy around the details
for now. HRICH

.AVIATION...
