Troughing influences will occur during the weekend and lead to generally above normal mixing and steady to strong southerly and westerly transport winds. Ventilation will be good to excellent therefore making the period a clean-out event. Widespread shower activity is also expected.

Some residual troughing likely Mon then brief-weak ridging before another disturbance impacts the area on Wed. Afternoon mixing will remain in the near to above normal category with fluctuating overnight inversions. Transport winds will generally be NW-W-SW with the strongest flow likely on Wed while the weakest occurs on Mon. The lowest ventilation day appears to be Mon with improvements thereafter. Another possible clean-out event for Wed. Can't rule out some residual light showers across the north/east Mon then next chance occurs on Wed.
