.DISCUSSION...
Cold front is moving into northwest part of forecast area at this
time, with continued southward movement expected today.  By day`s
end, front should lie just south of the area, with northeast and
east winds providing an upslope component.  Weak disturbances in
northwest flow aloft will provide enough lift to release
instability, with good chance of thunderstorms, mainly across
southern sections, near the front today and tonight.  Abundance
of moisture and expected slow movement of thunderstorms will keep
threat of heavy rains as a primary concern.  Northeast and east
sections expected to be more stable, owing to slightly drier post-
frontal air associated with filling surface ridge.

Threat for showers and thunderstorms will continue for the next
several days, with western and northwestern sections being
favored, as northwest flow aloft will provide opportunities for
convection to move in from the higher terrain, while southeast
low-level flow will keep moisture and instability maximized over
western sections.  Models suggest that a shortwave trof will
arrive Thursday night, with chances for showers and thunderstorms
increasing Thursday night and Friday morning.  Northwest flow
prevails through Monday, with continuing chances for rain.
