FORECAST

The weekend brought a few more rounds of welcome rainfall. While most of us didn’t see much, at least it kept temperatures from getting too hot. Those cooling showers go away today, bringing a return of heat.

HEAT HIGH

The infamous heat high that’s cranking up temperatures to our east slides back in our direction starting today. It’ll be almost directly overtop of us by Tuesday and Wednesday. The end result: a rain-free, triple-digit stretch.
