.DISCUSSION...

An increase in mid-level cloud cover can be expected over the next few
hours. General winds are expected to remain very light and variable in
direction. However, virga showers could result in a sudden increase in
winds at any moment, which would most likely originate from the west or
northwest. This threat will diminish after sunset. Appreciable RH
recoveries can be expected overnight. Gusty southeasterly winds with
gusts 25 to 35 MPH are expected after 1200L Wednesday with scattered to
numerous showers and thunderstorms likely after 1500L. Gusty and erratic
winds are possible near thunderstorms. The strongest storms should end
by early evening, but a slight chance of showers or storms may persist
through 2400L.
