The Western Carolinas are experiencing an early summer heat wave, with temperatures reaching the upper 80s in the Upstate and mid-80s in the mountains on Thursday and Friday. Saturday is expected to approach 90 degrees, which would break the current record. However, a cold front is set to push through on Sunday, bringing a dramatic 15-20 degree drop in temperatures and a chance of showers.

Why it matters

This early summer heat is occurring about 6 weeks ahead of the typical timeline, raising concerns about drought conditions and the impact on plants and gardens. The sudden cool-down on Sunday will provide some relief, but the region remains in a dry pattern with no drought relief in sight.

The details

The hot, sunny weather will continue through Saturday, with gusty southwest winds making it feel a bit cooler. Overnight lows will remain mild, in the upper 50s to low 60s. A weak cold front on Friday will bring only isolated showers to the far northern mountains. The bigger change comes on Sunday, when a cold front pushes through, bringing a chance of showers between 8 a.m. and 1 p.m. Most areas will only see a trace to 0.1 inches of rain. However, the front will also cause temperatures to crash, with highs only reaching the low 70s in the Upstate and mid 60s in the mountains - a 15-20 degree drop from Saturday.
