Upstate residents are bracing for a shift in the weather this week. After a stretch of hot and sunny conditions, thunderstorms are expected to interrupt the sunshine briefly on Thursday, just in time for Juneteenth celebrations.
The main concern will be afternoon storms, followed by a significant rise in temperatures heading into the weekend and early next week.
Thursday: Afternoon Storms Expected
The National Weather Service in Greenville-Spartanburg predicts that showers and thunderstorms will develop after 3 p.m. on Thursday. While the storms are not expected to be widespread, any storm that forms could bring brief, heavy downpours and lightning, which may affect outdoor activities and travel along major routes like I-85 and I-26.
Residents with outdoor plans for Juneteenth should keep a close watch on the sky and have a plan to move indoors if thunder is heard.
Friday and Saturday: Sunny and Hot
By Friday, the weather will clear up, with sunny skies returning and high temperatures reaching around 91°F. The sunny conditions will continue into the weekend, with temperatures climbing into the low 90s by Saturday. These warm conditions will make it feel like summer is in full swing.
Sunday: Rising Heat
Sunday will be another mostly sunny day, with temperatures expected to climb into the low 90s again. As the weekend progresses, the heat will intensify, and residents should take precautions, including staying hydrated and limiting strenuous outdoor activities during the hottest parts of the day.
Monday and Tuesday: Start of a Heat Wave
As early next week approaches, temperatures are forecasted to soar into the mid-90s, marking the start of a summer heat wave. Sunny and dry conditions will persist, with the heat expected to last through Tuesday.
During this period, it’s essential for residents to take care, especially those who are vulnerable to extreme heat, such as the elderly and young children.
