.DISCUSSION...
Similar conditions today to yesterday as the overall pattern
remains the same with high pressure off the coast and well above
average temperatures continuing with highs near 90F. Winds will be
out of the SSW today, although winds above the surface are not
quite as strong so gusts are expected to remain in the teens.
Tonight winds will once again remain elevated leading to fair
dispersion, although there still remains a possibility of a brief
period of fog right around sunrise mainly in low lying areas.
