While summer doesn't officially begin until June 20, the infamous Carolina heat has already started. The National Weather Service predicts a 40-50 percent chance of higher than normal temperatures for the Carolinas this summer.
High pressure is in the Carolinas this weekend will bring even more sunshine. There will be a few more clouds with a weak cold front pushing into the Carolinas but the heat index could top triple digits for some by Saturday afternoon, ahead of the cold front. There is a slight chance for a thunderstorm on Saturday afternoon and evening, but most places will stay dry. Father's Day will still be warm, just not as hot as Saturday with highs in the mid-80s to near 90. High pressure will return for next week, keeping it sunny and warm with highs topping out at right around the seasonal average. The heat index could make it feel like it is in the upper 90s to low 100s. If you are going to be doing any outdoor activities, be sure to take frequent breaks and stay well-hydrated.
By Sunday, high pressure will begin moving off the New England coast, gradually increasing easterly flow. Despite moderate instability, the lack of a strong trigger and weak winds aloft means any showers will likely be confined to the southern Midlands and CSRA.
Highs will range from around 90 near the North Carolina border to the mid-90s in the CSRA, with the heat index reaching the middle 90s to around 100.
If you plan to take Dad out this weekend, here are some simple steps to help plan your day:
- Plan your physical activity before 10 a.m. or after 5 p.m. to avoid the hottest parts of the day.
- Hydration needs vary depending on activity level, work type, sweat rate and outside temperatures. Ideally, water and hydration fluids should be cold, easy to access and easy to refill.
- Wear short-sleeved, lightly colored clothing when outdoors.
- Summer camps should schedule many rest breaks in the shade throughout the day.
Heat index values are based on shady, light wind conditions. Exposure to full sunshine can increase heat index values by up to 15 degrees, according to the National Weather Service.
In general, dangerous conditions would occur as soon as the heat index hits 105 degrees. Conditions are considered extremely dangerous if the heat index is 126 degrees or higher. If you want to know your heat risk, click here: Current heat risk
