Monsoon's last stand for 2014Posted: Updated:
PHOENIX -- Monsoon moisture has begun to interact with some unstable air. As a result, Friday afternoon is already producing a fair amount of big thunderstorms around the state.
Storms formed south of the Valley mid-afternoon and resulted in a Blowing Dust Advisory for a time. For the most part, the blowing dust did not have much of an impact.
As we head into the overnight hours, showers and thunderstorms will continue to be scattered in nature.
As a cold front located in California pushes in, we'll see an increase of rainfall on Saturday, especially Saturday afternoon. Right now, it still looks like much of the Valley will get around 1 inch of rain Saturday.
The storm will also bring us the first fall-time temperatures of the year. By Sunday, as skies clear, we'll see highs only in the 80s in the Valley with some locations getting into the 60s during the early morning hours. And we're expecting those cooler-than-normal temperatures to be in place much of the rest of next week.
