The National Weather Service has issued a heat advisory starting Wednesday, July 4th at 11am to Thursday night.
Heat index values are expected to peak from 102 to 110 degrees on Independence Day and again Thursday afternoon. The combination of hot temperatures and high humidity will likely lead to an increased risk of heat related stress and illness. The very young, the elderly, those without air conditioning, and those participating in strenuous outdoor activities will be the most susceptible.
Also, car interiors can reach lethal temperatures in a matter of minutes.
The heat and humidity over the next couple of days will be extremely dangerous. Given the number of outdoor activities associated with the 4th of July, the concern for heat related illnesses is only heightened. Take extra care over the next couple of days. The heat will be stifling for those outdoors, with little relief in the shade expected, as very light wind is forecast. Spend as much time indoors in air conditioning as you can.
Only minor relief is anticipated at sunset, through about 10p.m. as heat indices will still be in the upper 80s to mid 90s the evening of the 4th.
