ALT High temperatures in the 90s to low 100s will make for a significant heat wave across the central and eastern U.S. beginning on Sunday and lasting through next week. These hot temperatures combined with high humidity will lead to heat indices of 100-110 degrees, and locally as high as 115. Low temperatures only dropping into the 70s will provide little overnight relief. Multiple days of Major to Extreme HeatRisk are forecast across the Mississippi and Ohio Valleys next week. These levels of heat mean health impacts become more likely in general, and may occur in ANYONE without adequate hydration or cooling. High or moderate extreme heat risks cover much of the U.S. east of the Rockies July 4-5, with a broader slight risk through July 7 extending as far west as the Great Basin. Heat indices of 100-110 degrees are possible, and warm nights in the 70s-80s may limit relief over the holiday weekend. Stay informed and take steps to protect yourself from heat related illnesses.
