Forecast Discussion:
There is a lot to discuss regarding the weather today, with a strong Sunday system forecast to impact the entire state with ample rain amounts in the southern half and wintery mix/snow in the higher elevated regions to the north, so let's dive in!
Beforehand, high temperatures will approach the 80°F mark over the next three afternoons. Higher pressure has established overtop the desert southwest but will quickly vanish as we begin to see Sunday's storm system exert its influence on Saturday. Moderate breezes out of the southwest will persist throughout Saturday before switching abruptly at the arrival of an impressive frontal boundary. A squall line draping southwards will sweep across the state early Sunday morning, dropping temperatures and dumping high amounts of precipitation.
Afterwards, scattered showers will continue to bring rain to the valley throughout the afternoon with residual storms possibly moving through the metro area Monday morning. After all is said and done, Phoenix could see up to half an inch of rain by the end of Easter Sunday, and potentially another quarter to a half inch on Monday.
In the matter of air quality, ozone is forcast to be Moderate today and tomorrow due to the higher pressure and light winds. By Saturday, the active weather and cloud cover will hinder the ability for ozone to form at the surface. Particulate matter will remain in the Good AQI, despite the strong winds expected on Saturday. Prior rainfall has helped to stabilize local soils, resulting in a lower possibility for any blowing dust concerns.
Be sure to check in with us tomorrow for the weekend forecast!
