...FIRE WEATHER WATCH IN EFFECT FROM WEDNESDAY EVENING THROUGH
THURSDAY MORNING...

.DISCUSSION...Dry weather is expected during the day Wednesday.
However, as an upper low moves into the Pacific Northwest later
Wednesday, rain chances will increase and there will be slight chances
of thunderstorms.  The thunderstorm potential has prompted the issuance
of fire weather watches through Thursday morning.  Rain chances will
decrease Thursday morning before increasing again Thursday afternoon.

Wetting rain chances are low, but remain possible by Thursday afternoon.

High temperatures will be rather cool in comparison to the last few days...
in the 60s on Wednesday and only around 60 degrees on Thursday.

Winds will generally be on the lighter side, generally 10 mph or less.

With the cooler temperatures and increased rain chances, relative humidities
will be higher as well.  MIN RH values will be in the upper 30s to lower 40s
on Wednesday and about 65 to 70 percent on Thursday, with excellent recoveries
overnight.

Dry weather returns again Thursday night into early Friday before more rain
and thunderstorm chances return for the weekend, though at this time the
chances are only about (20-30%) on Saturday and 20% on Sunday.
