.DISCUSSION...Precipitation chances will be less than 10% with
diurnally driven winds under 10 mph today through Saturday
afternoon. An approaching system late Saturday will produce a
marine push through the Cascade gaps, which will result in
west winds increasing to 7 to 12 mph Saturday evening. RHs will
decrease into the upper 30s to lower 40s today, but the marine
push Saturday will keep afternoon RHs in the lower to mid 40s.
