.DISCUSSION...High pressure will maintain dry and stable
conditions at the burn site through the weekend with light,
terrain-driven diurnal winds. Temperatures today will trend a bit
warmer and humidities a bit lower compared to yesterday. Few to
scattered high clouds will remain possible through the day,
clearing out in the evening. Mixing will be poor through the
weekend. A weak but dry weather disturbance crossing the area on
Monday will have the potential to bring increased mixing, with an
increase in southwesterly flow. A somewhat stronger storm system
is expected to bring stronger southwesterly flow on Wednesday
before a cold front arrives on Thursday. However, latest models
have trended weaker with this storm with precipitation now
remaining north of the burn site.
