Forecast Discussion:

Temperatures are still running warmer than normal for this time of year. 77 degrees was recorded for Nogales which is 8 degrees above the normal value. We did see some breezy afternoon winds out of the southwest. Otherwise, it was a pretty typical day in Nogales. Both PM10 (dust) and PM2.5 (smoke) landed in the Moderate Air Quality Index (AQI) range.

Today the low-pressure system has moved in over the state. Slight cooler temperatures today and tomorrow from what we've been seeing. This is a dry and fast-moving system, so no rain or major impacts are expected. We will see an increase in our westerly breezes as the system begins to exit Arizona. Tomorrow winds will quiet back down but temperatures will remain in the low 70s.

This weekend, another low-pressure system is going to deepen over the southwest. The major impacts from this next disturbance will be increased west-northwest winds and temperatures dropping into the mid to high 60s. We won't see this take place until the afternoon on Sunday. Until then, enjoy the nice next couple of days!

We will start March off with a high-pressure system rolling into our region. Expect more warm days to the start off the new month!

As for air quality, particulates are forecast to remain in the Moderate AQI category through Saturday. Morning and evening stagnation allows for these levels to increase. With strong breezy winds expected on Sunday night, good ventilation should lower particulate levels into the Good AQI category. By Monday, PM10 and PM2.5 will go back to usual trends and be in the Moderate AQI.

Have a great day!
