A large area of high pressure, building into the mid-Atlantic, will bring plenty of sunshine with high temperatures in the mid-40s each day. In between, temperatures will drop to the teens in some outlying areas tonight and into the low 20s in the more urban areas.
Clouds will gradually increase Sunday as high pressure moves away to the east. Temperatures Sunday will recover to about 50 after another cold start.
The chilly temperatures are creating a dangerous situation for some who may not be prepared for the bitter cold. During the next few nights, the white flag is up for people who usually sleep outside in the Triangle.
