Synopsis and Discussion
High pressure in the vicinity just to the south of Arizona will keep the
air mass overhead fairly stable through Thursday. Sunny skies, light
winds and daytime temperatures in the mid to upper 70s are expected
through Friday. On the flip side, overnight inversions will be stronger
and daytime ventilation/mixing will be Marginal to Poor at best. This
means that a rapid accumulation of surface pollution can be expected,
painting the horizon with a visible Valley Brown Cloud. As a result,
expect to see PM2.5 levels jump into at least the lower Moderate range
of the Air Quality Index (AQI) by Wednesday and Thursday.
Check back tomorrow for the latest. Until then, have a good day!
