Extreme Heat Ahead for the Southwest

29 May 2020, 7:45 pm

The heat continues to build across the Southwest this week with several days of extreme temperatures in store for the region. The mercury will once again soar into the 90s and 100s for areas away from the coast. Another ridge of high pressure will be setting up across the Southwest over the next few days, so we will see temperatures climb well above average.

The heat is being driven by a big ridge of high pressure anchored across the Southwest, leading to a widespread sinking air. Remember, when air rapidly sinks, it compresses. That leads to air molecules moving faster. The friction from those invisible rapidly-moving air particles is what you feel as heat!

There will be little relief felt even in the overnight from the dangerous heat, so make sure you have a way to stay cool and a plan in place in case of power outages. Triple digit heat is in the forecast for most areas under the Excessive Heat Warnings. Highs are running 10 to 20 degrees above average. Many cities will see the dangerous conditions all week long and possibly into next week.

When extreme heat is in the forecast, be sure to take precautions to avoid heat related illness. Stay hydrated by drinking plenty of water and avoiding alcoholic beverages. Avoid prolonged sunshine and work during the cooler parts of the day, such as the early morning or in the evening. If you have to be outside during the afternoon hours, take plenty of breaks in the shade, wear light colored & loose-fitting clothing, and learn to recognize the signs of heat stroke.

For more on heat safety, here’s a handful of tips to help keep you and your family (and your pets!) safe. WeatherNation will keep you up-to-date on the latest forecasts and alerts for the Southwest. Check back with us for updates.
