Forecast Discussion:

Water vapor satellite this morning shows a well-defined area of low pressure sitting off the coast of California. This storm will be the main weather feature to watch this week!

The system will slowly move southward along the coast today and tomorrow before finally moving into Arizona Wednesday through the end of the week. Before this storm arrives, southwest winds of 10-15mph are in the forecast both this afternoon and tomorrow afternoon. By Wednesday, southwest winds of 15-25mph are likely along with increasing rain chances throughout the day into Thursday.

As another disturbance moves in directly behind this first system, there will be a renewed chance of rain on Friday.

Rainfall totals are not expected to be too high with this system, with most locations across Tucson in the 0.01-0.10 inch range. There is a chance of thunderstorms, which will be capable of producing gusty winds, brief heavy rain, and hail.

Temperatures are also forecast to plummet as cold air moves into the area. High temperatures will drop into the mid-70s on Wednesday and possibly down into the upper 60s on Thursday and Friday!

As for air quality, with the active weather throughout the week, both ozone and PM-10 are forecast to be in the Good AQI category.

Make it a great Monday!
