In Catalina and, more broadly, across the state of Arizona: The morning starts with mostly sunny skies and just a few clouds drifting through. Temperatures are already rising rapidly, with the mercury climbing between 77 and 96 degrees Fahrenheit, making for a very hot day. Winds will be moderate from the southwest, generally around 8 to 12 mph, with occasional gusts up to 15 mph, providing some relief from the heat. As the afternoon progresses, expect the hot conditions to persist with little change in the sky cover. No precipitation is expected, so outdoor activities should be planned accordingly. Be sure to stay hydrated and protect yourself from the sun during the hottest parts of the day. The weather remains dry and warm through the afternoon hours.
