Smoke Call Status: UFN, smoke calls will be on Mondays only at 1300 PST
Issued: 12:30 PM   Thursday, February 23, 2017
Discussion:
Cold northerly flow will bring in another weather system Friday that will linger through Saturday morning. This will allow afternoon dispersion conditions to remain quite active Friday. Higher pressure will be arriving over the North Ops region later in the day Saturday, so that will probably start to put a bit of a damper on afternoon mixing heights that day for some areas, but transport winds should keep dispersion active in spite of that. Afternoon transport winds will generally be W to S over the next few days.
