.DISCUSSION...Expect an upper-level ridge of high pressure to
begin progressing eastward out of the area today (Tuesday) but
temperatures will continue a warming trend with lower daytime RHs
as well. Offshore flow likely facilitates easterly winds to start
the day, however, these winds will wane in the afternoon and
eventually shift westerly in the evening. Otherwise, a cold
frontal boundary brings showers and breezy west winds back to the
area on Wednesday along with improved RHs and cooler temperatures.
