Things are cooling down heading into Labor Day Weekend

Posted: Updated:
PHOENIX (3TV/CBS 5) -

Unseasonably hot and dry weather continues into Friday across the Valley with tropical moisture changing the weather pattern this weekend.

Tropical Storm Lidia off the coast of Baja Friday morning is tracking toward the northwest over the next several days and will become a tropical depression by Saturday night, according to the National Hurricane Center.

This system is expected to send moisture into southern Arizona by Saturday. For the Valley, this will mean cloudy skies, higher humidity, and cooler temperatures with slight chances for storms through next Tuesday.

Isolated to scattered storms are expected across the high country Friday, with better storm chances this weekend as the moisture surge ensues. The best chances to see measurable precipitation from Lidia moisture will be across southwestern Arizona and southeastern California.

In Metro Phoenix, look for sunny skies and a high of 108 Friday, partly cloudy skies with a high of 102 Saturday and 101 Sunday. Highs will rise between 105 to 109 for the Labor Day holiday and into the middle of the week. Storm chances will range from 10 to 20 percent for the Valley.

    We may have to wait a little longer for fall to arrive in Arizona, but when it does, it's AMAZING. And that includes the fall colors. Yes, even in Arizona we get those reds, golds and yellows. It just takes a little bit of a road trip from the Valley to find them.
