A stronger upper level High Pressure ridge (the “arch” shaped portion of the yellow lines over the Pacific) will be replacing the weaker one that gave us the weekend sunshine for a great 4th of July Holiday Weekend, but first a little disturbance will bring in some clouds and cooler temperatures today that will warm back up quickly. Some locations in the valleys could see 90 degrees or above before the end of next week as a result of that strong high pressure ridge.
