Synopsis & Discussion
Forecaster: -M. Graves
Temperatures will continue to be unseasonably warm this weekend as a ridge of high pressure builds over the region. High temperatures will remain at least in the upper-mid 80s today through Sunday, with Sunday forecast to be the warmest day (the normal high is around 70°F!). Light winds are also expected through the weekend.

By Monday, the weather begins to change as a trough of low pressure passes over Arizona. Though Monday is still forecast to be a warm day (highs in the mid-80s), winds are currently forecast to be 15-20 mph and out of the southwest in the afternoon. Then, as Tuesday rolls around, high temperatures are expected to plummet to around normal, or slightly below.

Air quality-wise, PM-10 and PM-2.5 are forecast in the Moderate Air Quality Index (AQI) category through at least Sunday, due to expected stagnant weather conditions. By Monday, both pollutants are expected to decrease due to the windier conditions--can't rule out elevated levels overnight, though. By Tuesday, both pollutants should increase again due to the lighter winds and cooler temperatures. In all, there is uncertainty in how high particulates will rise each day.

Check back on Monday for the next Nogales air quality forecast.
