*** Note - Due to the wet weather and Thanksgiving holiday this product may not be updated for several days ***                            Deep low pressure over CA will continue to produce deep vertical mixing through Friday. Transport winds will be moderate to locally strong from variable directions. Any smoke created will disperse easily, and occasional precipitation will add to that. More wet unsettled weather expected late Saturday through next week will continue the trend of active smoke dispersion.
