The USDA Agriculture Research Service, in cooperation with the National Weather Service, predicts emergency heat-stress levels for Monday, July 13 and Tuesday, July 14 across a large region of the central U.S. stretching from Texas into Nebraska and Iowa. Heat-stress risk is due to high temperatures, higher humidity, low wind speeds and little cloud cover.
The forecast indicates the heat-stress risk begins to decline, particularly in northern areas, on Tuesday and through the rest of the week. Some areas in Texas, Oklahoma, Arkansas, Louisiana and Mississippi however will experience severe heat through the week. The Heat Stress Forecast Map is available online from USDA.
