Forecast Discussion:

Our next storm system continues to sit off the coast of California. This area of low pressure will move into Arizona Wednesday through Friday, which will increase winds, drop temperatures, and bring a slight chance of showers and thunderstorms to the area.

Winds are forecast to be in the 10-15 mph range this afternoon before increasing to 15-25mph tomorrow afternoon, with higher gusts possible. Not expecting widespread dust with these winds; however, we could see some pockets of blowing dust along the I-10 both east and west of Tucson, so use caution if you are traveling.

Rainfall totals will be rather low as there is not much moisture associated with this storm for the Tucson area. There will be a slight chance of rain tomorrow, with a slightly better chance of rain on Friday (the keyword is slightly). Rainfall totals are forecast to be between a 0.01-0.15 inches.

Afternoon high temperatures will also drop significantly by the end of the week as cold air dives into the state. High temperatures tomorrow are forecast to be in the upper 70s before dropping into the low 70s on Thursday and Friday, which is well below average for this time of year.

Air quality is forecast to remain in the Good AQI category through the forecast period.

Have a great Tuesday!
