.DISCUSSION...
Temperatures will be quite warm (by November standards) on Wednesday
with highs expected to be in the lower 70s. Humidity will become
moderately low in the afternoon, but winds are currently expected to
be light as an area of high pressure moves into the area. With
relatively light winds, smoke ventilation will be fair at best during
the day. Also with light winds, the wind direction will depend on the
timing of the high pressure ridge moving into the area, so if wind
direction is important for the burn, it will be good to verify the
latest forecast tomorrow and/or Wednesday morning.
