Columbia, SC, is set to experience a wave of oppressive heat this week, with heat index values soaring past 100°F ahead of the Juneteenth holiday. The combination of high temperatures and high humidity will create dangerously hot conditions, posing a significant risk for heat-related illnesses, especially for those who spend time outdoors.
According to the National Weather Service, Wednesday will be sunny with a high of around 95°F. However, due to the high humidity, it will feel as hot as 101°F. Southwest winds will remain light, offering little relief from the intense heat. Health officials are urging residents to stay hydrated, seek air-conditioned spaces, and avoid strenuous outdoor activities during the peak afternoon heat.
This extreme heat continues into Thursday (Juneteenth), with a high of 95°F. In the afternoon, there will be a renewed chance of thunderstorms after 2 p.m., which could provide some temporary relief but also bring risks like gusty winds and heavy rain.
Storms Become a Daily Feature
Starting on Friday, the pattern of afternoon thunderstorms will become a daily occurrence, adding to the already intense heat. Friday will bring a 30% chance of thunderstorms, mainly after 2 p.m., with a high of 94°F. As we head into the weekend, Saturday and Sunday will remain hot and humid, with temperatures in the mid-to-upper 90s. Both days will carry a chance of scattered thunderstorms, which could create hazardous driving conditions, especially for commuters along major highways like I-26 and I-20.
With thunderstorms possibly reducing visibility and causing sudden downpours, drivers should remain cautious and be prepared for sudden changes in weather.
Extended Heat Expected into Next Week
This persistent summer heat will continue into early next week. Monday will see a high near 98°F, with a mix of sun and clouds. The hot and humid weather pattern will likely stick around, and residents should remain prepared for extreme heat conditions in the coming days.
Columbia is facing a long stretch of extreme heat with the potential for thunderstorms. Residents are advised to take extra precautions, stay hydrated, and avoid outdoor activities during the hottest parts of the day to stay safe.
