.DISCUSSION...
Winds are expected to remain fairly light through much of the day
with a ridge of high pressure sliding across the area. Morning winds
will feature a greater northerly component and will be influenced
more by terrain.  Gradually, a greater westerly component will
evolve toward midday, with winds shifting to south of west by late
afternoon.  With the light winds, smoke dispersion is unlikely to
exceed fair this afternoon.  There will be a small chance for light
rain Thursday morning, otherwise the main weather feature will be a
shift to strong and gusty northerly wind between 8 and 10 am Thursday
morning.
