Extended Outlook:  Tuesday - Thursday
Isolated to scattered shower activity will continue in portions of the W, N & E Mon night into Tue morning then taper off Tue afternoon as the upper level trough shifts eastward ahead of ridging building offshore. The ridge will continue to strengthen along the coast Wed & Thu with the passage of an inside slider type upper level trough across the NE Wed night through Thu morning bringing the potential for moderate to strong offshore flow to North Ops. Smoke dispersion conditions will remain active across the majority of North Ops through the period, supporting by the troughing influence and breezy NW winds Tue and then N-NW to NE winds developing Tue night and then broadening and strengthening over the area Wed & Thu with both day & nighttime RHs lowering quickly.
