.DISCUSSION... Not much has changed for the long term forecast.
Next week still looks very mild with highs in the upper 60s to 70s
each day. Relative humidity will drop to between 12-20% each day.
The tricky part of the forecast will be getting enough wind to
increase the smoke dispersal but not too much. Monday and
Wednesday may have issues with getting enough wind to reach fair
smoke dispersal. Light and variable winds staying mostly less than
6 mph are expected each of those days. Thursday and Friday will
have better chances to see enough southerly or westerly winds to
reach fair to good smoke dispersal.
