Forecast Discussion:
On this Friday morning, the weak disturbance just south of Arizona continues to sit in the same spot, a trough of low pressure is centered over the Idaho/Montana border, a ridge of high pressure is off the West Coast, and finally, another area of high pressure is over the midsection of the County. If you are tired of keeping track of all these weather features, the good news is nothing will really change with the pattern through early Sunday. As a result, expect some easterly breezes from time-to-time, and just enough moisture left around for very isolated thunderstorms chances.By late Sunday into the first part of next week, the ridge of high pressure off the coast will move eastward, which will shift the whole pattern east. As this transition takes place, another weak disturbance may drop down the back side of the low to the north resulting in a slight increase in storm chances late Sunday into Monday and again Monday into Tuesday. Once again, not expecting coverage to be widespread but still something to watch.
As for air quality, forecasting ozone to be in the Moderate AQI category today through Monday, and PM-10 and PM-2.5 are forecast to be in the Good AQI category.
Have a great weekend!
