.SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/...
KEY MESSAGES:
- Continued warm and dry weather.
--------------------------------------------------------------
Valley fog is again possible Friday morning with mostly clear
skies and calm to light winds and additional moisture in river
Valleys. Weak upper troughing will progress in from the north,
accompanied by height falls into Saturday, but with prevalent
surface dry air and weak forcing, chances of any rain seem low,
though high clouds will be possible Saturday. Regardless, there
is little temperature uncertainty with high confidence in the
upper pattern (highs Saturday slightly above normal).
Fog chances and the degree of cooling Saturday night will depend
on the extent and density of high clouds. Temperature may be
anywhere from near-normal with minimal fog to slightly below
normal with valley fog.

KEY MESSAGES:
- Low rain chances Sunday; forecast uncertainty increases early
  next week.
------------------------------------------------------------------
The affiliated surface shortwave is most likely to pass late
Saturday into Sunday, though surface dry air will continue to be
present with weak forcing. This will again keep rain chances low
with even the 90th percentile 24-hr QPF showing
