Heating up! Rain chances coming, too

PHOENIX — A warming trend is setting up across the Desert Southwest, with dry conditions holding for now, but some tropical moisture could shake things up by the weekend!

The week starts off with near seasonal temperatures but we heat up fast! Afternoon highs will be back in the triple digits and stay there all week.

Two weather systems are in play: one moving through Arizona now, and a stronger one settling into the Great Basin. Together, they’ll keep our temperatures steady with some breezy afternoons, especially in western Arizona.

By Friday and Saturday, high pressure builds in and temperatures will rise to the 106-degree range.

Heat risk will increase, especially across lower desert areas like the Valley, so take precautions if you’re spending time outdoors.

As we head into the weekend, a cutoff low near Baja California could pull in moisture from a weakening tropical system to our south. If that moisture makes it north, we may see a slight chance for rain late Saturday through Monday.

However, model disagreement is high, so confidence remains low for measurable rainfall at this point.

We’ll be tracking it all closely, so stay tuned to ABC15 for updates.
