A significant increase in temperatures across the Carolinas is predicted for the weekend, with temperatures expected to remain 15-20 degrees above normal throughout the week. The weather is being driven by a strong Bermuda High off the Carolina coast, which typically occurs in summer months. Despite this, there are concerns that surface moisture could create dense fog overnight, potentially impacting visibility during the morning commute. The persistent high pressure system keeps rain away and maintains a southerly flow bringing warmer air into the region. Despite increasing rain chances, temperatures are predicted to remain unseasonably warm throughout the weekend. The weekend's weather is expected to be largely dry, allowing for an extra hour of evening daylight.
