The mercury may be climbing toward historic levels.

High pressure continues to expand across the southwest. As a result, daytime highs run 8-10° above average across southern Arizona. Today’s forecast high of 109° would tie the old record set on this date in 2008.

Southeastern Cochise County has a 10% chance of a shower or thunderstorm today, as moisture begins to exit the state.

Daytime highs will continue to be in the 108-111° range through Father’s Day weekend. Friday and Saturday’s forecast high temps will come a degree or two away from reaching historic levels. Ample sunshine is expected through early next week.

This is dangerous heat & the hottest stretch of weather in almost two years. Drink plenty of water, limit your time outdoors & make sure friends and loved ones have a cool place to stay. Know the signs of heat stroke, which include headaches, confusion & lack of sweat.

TODAY’S MONSOON SAFETY AWARENESS WEEK TOPIC: MICROBURST WINDS

Microburst 101

While small in size, microburst winds can cause major damage to your property. A thunderstorm is required for a microburst to develop. Rain cooled air rapidly descends into the valley floors, fanning out once reaching the desert. It’s this fanning out process that can produce winds in excess of 100 MPH over a few city blocks.

Microbursts are also catalysts for dust storm development. Often times during the early part of the Monsoon, we’ll see several haboobs develop along I-10 between Marana and Picacho Peak. This is because microburst winds kick up the dust across the rural portions of Pinal County & gather momentum as it heads toward Phoenix.
