ST. LOUIS—The St. Louis area is expected to be under another blanket of heat on Friday as the heat index is again predicted to reach the triple digits.
The National Weather Service says it will feel almost 105 degrees across parts of the region on as a heat wave continues to bake Missouri and Illinois.
The forecast calls for highs in the low-to-mid 90s with high humidity and sunshine, which will make it feel about 104 degrees.
“There’s also a slight chance for a small and brief bubble up storm in the afternoon,” said News 4 Meteorologist Kent Ehrhardt.
Federal weather officials say the steamy weather could cause rolling blackouts and buckled pavement.
Meanwhile, public health officials are opening cooling centers and warning people to drink plenty of fluids, check on neighbors and take precautions if they’re outside. People who need a cooling station and seniors and disabled who need assistance paying air conditioning bills can call United Way’s 2-1-1 for help.
The air quality forecast for the day is again in the orange level, meaning that persons with special needs, children and the elderly are at a high risk.
“Remember to pay special attention to spending long durations outside,” said Ehrhardt.
Friday evening will see temperatures drop into the 70s with a chance for a late-night shower or storm.
Looking ahead, a few storms are expected to develop both Saturday morning and afternoon. Those should slide south of the St. Louis Metro area by the evening.
“Otherwise it’s going to be hot and humid, but a bit cooler,” said Ehrhardt.
