Extreme Heat Warning

Slightly above normal temperatures are expected today as afternoon highs are likely to remain just shy of 110 degrees. As high pressure strengthens over the region, temperatures heat up to well-above normal levels starting Tuesday and approach near record levels. The well-above normal temperatures will result in widespread Major to Extreme HeatRisk into next weekend with Extreme Heat Warnings in effect. Little to no thunderstorm chances expected throughout the week.

Strong high pressure over the Southwest will lead to abnormally hot temperatures through at least the next week with temperatures 5-10°F above normal and near record territory at times. This will result in Major to Extreme HeatRisk across much of the lower deserts. The Extreme Heat Warning remains in effect through next Saturday, 29 August for much of the area.
