Why is it 70 degrees in December?

Temperatures Saturday afternoon Dec. 12

The unseasonably warm weather is catching many people off guard as we head into the Christmas season.

The official high at RDU Saturday was 75 degrees, a whopping 21 degrees above the average high temperature of 54.

The mercury climbed even higher in Cumberland County. The Fayetteville Airport measured a temperature of 78 degrees shortly after 3 p.m. Saturday afternoon.

Despite the warm temperatures, no records were broken today. The previous record of 79 was set at RDU in 2007.

Why the warm up? Don't blame global warming. A large area of high pressure is extending over the southeast, bringing us dry conditions, and southerly winds. Those winds are tapping into a much warmer air mass, which should linger through Monday.

A cold front will arrive on Monday, triggering rain by the end of the day. It will also deliver slightly cooler temperatures for the middle part of next week.
