Synopsis and Discussion

Strong westerly winds, Friday, have kept the air mass well mixed and code GREEN. High pressure will settle over region, Saturday, allowing for winds to decrease and an increase in low level air mass stagnation. Particle pollution looks to climb back to the MODERATE range, Saturday. A weak disturbance will roll through the state, Sunday into Monday providing clouds and possibly a few showers. The clouds will limit any afternoon verticle air mass mixing leading to a continuation of code YELLOW, Sunday and Monday (GENTRY).
