Forecast Discussion:

A period of unsettled weather will be in store for Arizona over the next several days. For today, isolated thunderstorms will be possible in/around the Rillito area in the afternoon because of a low pressure disturbance overhead.

Then Saturday into Sunday, low pressure will provide continued thunderstorm and rain chances for the Rillito area. Saturday night into Sunday morning is currently looking to be the window for the most rain. Breezier winds out of the west-southwest are also expected Sunday afternoon.

Then by Monday, things look to calm down and dry out a bit in the wake of the low pressure circulation. But another low pressure wave is projected to quickly follow by Wednesday.

The main thing to note here is the potential for brief blowing dust associated with gusty thunderstorm winds. Sunday's breezes may also result in higher PM10 (dust) levels. But any rain will help to suppress and limit PM10.
