.AVIATION...It is apparent that orographic effects along with some
limited assistance with dry air advection is keeping the terminals
vfr right now. The question is will a low level northeasterly
component bring some lower ceilings southwest into the Great
Valley. The possibility exists and forecast cha to become mvfr due
to ceiling and fog while forecasting a deteriorating situation at
tri due to mvfr fog. Models indicate a strato cu ceiling hangs
around through much of the day today but it looks like it will be
a few thousand feet above mvfr category. The ceiling may scatter
out later this afternoon.
