.DISCUSSION...

Temperatures are going to continue to gradually cool down throughout
the next couple of days as the ridge over the region weakens and
there is more influence from the trough upstream over the E Pac
waters. This will allow for there to be a slight increase of
moisture, although min RH values will be roughly around the same, at
29 percent for the rest of this afternoon, as well as tomorrow.
Southwesterly winds also will become more gusty during the afternoon
hours, with gusts up around 26 mph by later in the afternoon
tomorrow.
