ALT Key Messages for Early July Heat. The prolonged heat, at times dangerous, in the Southern Plains will continue through the weekend and into next week with the combination of hot temperatures and high humidity. The heat and associated risks will expand to the Southeast and southern Mid-Atlantic by mid to late week, particularly on July 4th, and continue into next weekend. The heat threat will grow across California’s Central Valley by mid to late next week, and the Central Valley of California is likely to have high temperatures well into the 100s and perhaps into the 110s creating hot and potentially dangerous heat conditions. A moderate risk (40-60%) of excessive heat continues into next weekend (July 5-7) . Heading into the July 4th holiday period, use caution for outdoor activities during the periods of high heat and humidity. Drink plenty of water and limit time during the peak of the heat.
