Forecast Discussion:

Today through Sunday, a broad trough will be spread over a good portion of the United States, resulting in some weak disturbances moving through the state, but the only impact for the Tucson area will be an increase in breezes from time to time and afternoon highs staying in the mid to upper-60s, which is well below average for this time of year.

By Monday into Tuesday, a ridge of high pressure will build over the state as another area of low pressure drops down the coast of Southern California. As the high moves overhead, expect afternoon high temperatures to rise into the low 70s on Monday before increasing into the upper 70s to low 80s on Tuesday, which might sound hot, but that is average!

Looking out a bit further, the storm that will drop down the coast to start this week may move into Arizona by the end of the week, dropping highs back into the 60s by Thursday and even bringing a slight chance of rain back to the weather picture. Plenty of details to iron out, but it will be something to watch.

As for air quality, ozone did rise into the Moderate AQI category yesterday as the weather system moved out of the area. Over the next several days, expect these values to lower a bit back into the upper Good AQI category; however, with high pressure building back in, forecasting values to rise back into the Moderate AQI category Monday and Tuesday. PM-10 and PM-2.5 are forecast to be in the Good AQI category through the forecast period.

Have a great weekend!
