Forecast Discussion:
It's a cloudy Friday morning in the Valley of the Sun as some subtropical moisture streams over the region. Looking at water vapor satellite this morning, the most prominent feature that will impact our weather is a large ridge of high pressure over the Gulf of Mexico, with an axis running east to west from the Bahamas to west of the tip of Baja. At the same time, a trough of low pressure is off the coast of the Pacific Northwest.The trough off the coast of the Pacific Northwest will continue to slowly drop southward along the coast and stall out off the coast of Northern California late tonight into Sunday. As the trough stalls, the high over the Gulf of Mexico will shift slightly further west. This weather setup will result in a more robust southwest-to-northeast flow in Arizona, which will help to draw in some moisture, especially across the southern part of the state. Phoenix will be right on the northern fringes of this moisture stream, so while we will see clouds through the weekend, only expecting a slight chance of rain Saturday and Sunday.
As the high over the Gulf shifts back to the east on Monday, the trough along the coast will finally start to drop southeast and into Arizona Tuesday into Wednesday. This will again bring some slight rain chances to the area late Tuesday into Wednesday.
As for air quality, with light winds expected through the period, PM-10 and PM-2.5 are forecast to be in the Moderate AQI category through the forecast period, with the highest concentrations predicted to be in the late evening and early morning hours.
Have a great weekend!
