.DISCUSSION...
Expect southwest winds around 10 mph with gusts to around 20 mph this
afternoon.  The lower atmosphere will be fairly unstable this afternoon
which will allow smoke to rise rapidly.  Smoke dispersal will initially
be poor due to low mixing heights, but will improve through the afternoon
as temperatures warm up and mixing heights rise to over 3000 ft. A cold
front will move through the area this evening which will shift the wind
to the northwest.
