Service.

.DISCUSSION...A cool and moisture rich Pacific system will impact the
region through Thursday. Showers will continue to become more
widespread through the afternoon, with a few embedded
thunderstorms also possible. Shower chances then remain high
overnight, and while a lull might develop briefly, elevated shower
chances are noted throughout Thursday as the core of the low
pressure shifts overhead. In general the forecast supports around
0.60" to 0.90" of water or so, and given the colder air associated
with the system around 3" to 6" of snow by events end. High
pressure starts to build back in Friday into the weekend,
supporting a period of drier and more stable conditions along with
a gradual warm up. Models then generally support (~80% chance)
some system early next week. The breakdown appears to be around
50% supporting a moderate strength system, 30% a weaker more
grazing type system, and 20% more of a continuation of
drier/milder conditions.
