Smoke Call Status: UFN, smoke calls will be on Mondays only at 1300 PST
Issued: 12:30 PM   Wednesday, March 29, 2017
Discussion:
The unsettled weather pattern over the next few days will keep any extended periods of limited dispersion from developing. Afternoon dispersion conditions should remain fairly active. Although afternoon mixing heights will be lower Friday, there will be substantive enough winds to keep dispersion active.

Extended Outlook:
Saturday through Monday:  Northerly transport winds will be lighter Saturday under the high pressure, so it is likely to have the least favorable afternoon dispersion through the period. The arrival of another trough for Sunday into Monday will keep afternoon dispersion conditions relatively active.
