The fall season's strongest cold snap for the state line area will provide a shock to vibrant plant life.
Forecast low temperatures around the state line region will drop into the mid to low 30s Thursday morning. With less wind, and times of calm air, areas of frost will develop in the pre-dawn to post-sunrise time frame.
The National Weather Service has issued a Frost Advisory in all counties of the ABC 27 viewing area, starting in the early morning and expiring at 9:00 am Thursday. Area-wide temperatures will drop to the mid to low 30s, with slightly warmer conditions for the immediate coast.
Frost development is most favored in open fields, lawns, and rooftops, especially those not covered by trees or other structures. Air temperatures do not have to reach the freezing point (32°) for frost to form; under these conditions tonight, ground-level temperatures can be lower than observed air temperatures, which are typically measured at about six feet above ground.
Tender and sensitive plants can be damaged by the formation of ice crystals in the frost process. It is advised to cover plants or bring potted plants inside to provide additional warmth and maintain the health of the plant.
