Forecast Discussion:
Above-average high temperatures have returned to the Valley of the Sun, with a high temperature on Thursday of 85 degrees, which is 2 degrees above average for this time of year.From a big picture vantage point, high pressure will build back into the region today through the first part of next week, which will allow afternoon high temperatures to remain in the upper 80s to low 90s, well above average for this time of year. The one caveat continues to be a weak disturbance, which is now located about 500 miles off the coast of Northern Baja. This system will move eastward and then northward into Southern California Sunday into Monday before weakening further and lifting toward the northeast Tuesday. This system and associated moisture will increase clouds Saturday through Tuesday, along with breezy easterly winds Sunday through Tuesday morning. There will also be a very slight chance of rain Monday into Tuesday, but any rain is currently forecast to be very light and rather isolated. Nevertheless, at least there is a chance, no matter how small that chance might be!
As for air quality, ozone is forecast to be in the Good AQI category. PM-10 is forecast to remain in the Moderate AQI category through the forecast period, with concentrations lowering slightly Monday into Tuesday with breezy easterly winds helping to weaken the morning inversion.
Have a great weekend, and Happy Halloween!
