Heating Up Next Week

Afternoon highs are forecasted to be near to slightly below normal for the 4th of July holiday, a welcome sight for this time of year. Heat precautions should continue to be exercised if holiday plans take you outdoors. There will also be an abundance of mid and high level clouds today and some locations could even see a few sprinkles from the late morning through the evening hours.

Although seasonal temperatures are expected this holiday weekend, HeatRisk across the lower deserts will still reach the moderate category. Please practice smart heat safety if you have outdoor activities planned.

Make sure to follow these safety tips and properly dispose of your fireworks in order to prevent starting any fires.

Temperatures will warm well above normal during the middle part of next week with areas of Major HeatRisk developing across the lower deserts and portions of the higher terrain east of Phoenix. With well above normal temperatures and areas of Major HeatRisk developing, an Extreme Heat Watch has been issued for Tuesday July 7 - Thursday July 9 next week.

High pressure will build over the region next week allowing temperatures to heat back up above normal leading to widespread Moderate HeatRisk with areas of Major HeatRisk. Practice smart heat safety by drinking plenty of water and electrolytes and reducing your time outside during the afternoons.
