Forecast Discussion:

Today through early Sunday afternoon, not a lot of change in the weather. There will be a few passing clouds from time to time as some weak disturbances move through, but that is about it. If you want more active weather, changes will move into the weather picture late Sunday into Monday!

Water vapor satellite shows one disturbance over the Gulf of Alaska with another near the Aleutian Islands. These two systems will merge off the coast of the Pacific Northwest late Saturday into Sunday before moving toward the southeast into Arizona late Sunday into Monday.

Will this system bring rain? That is the million dollar question. If the storm shifts further east, it won't have much moisture with it, reducing rain chances, but for now, let's stay positive (if you like rain)! With that said, the best rain chances, right now, appear to be early Monday morning into the evening hours, with rain totals in the 0.25 to 0.50-inch range.

This system will also increase southwest winds on Sunday afternoon through Monday morning into the 15-25mph range. And last but not least, this will be a cold system, with afternoon high temperatures possibly dropping into the mid-50s on Monday and Tuesday!

As for air quality, forecasting PM-10 to remain in the Good AQI category through the forecast period.
