Temperatures will plummet into the 30s again on Wednesday night setting the stage for scattered frost across much of Eastern North Carolina. A Frost Advisory has been put into effect from 2:00 am to 8:00 am Thursday. Many plants are vulnerable to the frost since new and tender vegetation has pushed out because of the recent warm spell. Warmer conditions will return to the area on Thursday and continue through the weekend. Highs on Friday and Saturday could reach 80 degrees each day.
