The coldest air thus far in 2008 will send temperatures into the upper teens in many interior locations across Eastern North Carolina on Thursday night. Despite ample sunshine highs on Thursday afternoon will likely stay in the upper 30s setting the stage for a very cold night. High pressure from the Midwest will settle across the Carolinas and Virginia providing clear skies, light winds and dry air. Those conditions are ideal for maximum cooling. A warming trend will begin Friday and by the weekend temperatures should rebound into the upper 50s and lower 60s.
