Weather forecasters upgraded the Triangle to a freeze warning for the early morning hours of Wednesday, which means plant-damaging temperatures are now considered likely.
The National Weather Service said all the counties in the region could see readings of 27 to 31 degrees between 2 a.m. and 9 a.m. Wednesday because of cold air that has settled into the area.
Forecasters had issued a watch for cold air that could damage budding commercial crops, like strawberries and peaches, but they raised that to a warning late Tuesday. A warning means they consider problem conditions to be “imminent or highly likely.”
Never miss a local story.
The cold poses danger for home gardeners, who may need to cover sensitive plants Tuesday night.
The danger is only for a day, however. The forecast calls for overnight lows to range from the lower 50s to the upper 30s for the rest of the week. Daytime high temperatures were forecast to be in the 50s and low 60s.
