Forecast Discussion:

The monsoon will slowly start to make a return this week. Therefore, daily thunderstorm chances will enter the forecast again. As for rain, rain chances will improve towards the latter half of the week as moisture increases. Gusty winds will also be possible with any nearby, or distant, thunderstorms.

Air quality-wise, PM10 (dust) and PM2.5 could be locally elevated in the mornings when conditions are calm (like this morning). We also can't rule out brief dust from storm winds. However, both pollutants are forecast in the Good AQI category each day for now.

Check back again tomorrow for the next update!
