.Discussion...
Light to gentle east to southeast breezes will further slacken
through the start of the upcoming weekend. This will promote poor
to fair dispersion indices through the next several days. Despite
dry conditions, min RH values will hold above 70 percent and
recover in the mid 90 percentile overnight. Moisture will begin
increasing Saturday night with slight chances for rain returning.
