Forecast Discussion:

The current weather setup includes two prominent features: (1) a large ridge of high pressure sitting over the southeastern United States and (2) a trough of low pressure along the West Coast. With Arizona sandwiched between these two systems, some drier air will move into the state over the next few days.

With Arizona between these two systems, drier air will be pulled into the region from the southwest. The only caveat is a weak disturbance moving through the region today, which will increase thunderstorm chances slightly later this morning/afternoon, but after that chances will be very slight to none the rest of the week.

Thursday, the trough off the coast will begin to lift toward the northeast, which will open the door for high pressure to build back eastward. In fact, by the weekend, it is forecast to be over the Four Corners, switching the flow to a more southeast direction, importing moisture back into the state. This will lead to a slightly better chance of thunderstorms this weekend but also a warming trend, with afternoon highs in the low to mid-90s Friday into the weekend.

As for air quality, forecasting ozone to be in the Good AQI category through the forecast period.

Have a great Tuesday!
