Columbia, SC, USASun Jun 22 2025
The upcoming week is set to be a scorcher, with a significant heat wave hitting the region from Sunday to Thursday.

The heat index, which measures how hot it feels, is predicted to soar between 101 and 108 degrees Fahrenheit. This means the actual temperature will be high, but the heat index will make it feel even hotter. It's crucial to understand that the heat index is not just a number; it's a warning about the real danger of heat-related illnesses.
The weather pattern is being dominated by a large area of high pressure. This weather system is expected to stick around for the next few days, keeping the chances of rain and storms very low. On Sunday, there's a small chance of a few storms in the afternoon, but don't count on it to break the heat. The rest of the week looks mostly sunny to partly cloudy, with temperatures climbing higher each day.
Tonight, expect a partly cloudy sky with temperatures dropping to the low 70s. There's a slight chance of a few showers popping up, but they should clear out after sunset. The high pressure system is building in over the eastern seaboard, which will keep the weather mostly dry and hot for the next few days. This means it's time to start thinking about how to stay cool and safe.
The heat index is expected to be particularly high from Sunday to Thursday. This is the first major heat wave of the season, so it's important to take extra precautions. Heat-related illnesses can be serious, so make sure to stay hydrated and keep your pets in the shade with plenty of water. The actual temperatures will be high, with highs near 95 degrees Fahrenheit on Sunday and climbing to around 100 degrees Fahrenheit from Monday to Thursday.
