The National Weather Service in Omaha/Valley has issued a Frost Advisory, which is in effect from 1 a.m. to 10 a.m. Monday, for southeast Nebraska, southwest Iowa and northwest Missouri.
Low temperatures are forecast to fall into the mid 30s. With light winds, clear skies, and just enough humidity, frost formation is likely, especially in typically colder low-lying areas. Unprotected cold-sensitive plants may be damaged or killed by the frost.
A Frost Advisory means that widespread frost is expected. Sensitive outdoor plants may be killed if left uncovered.
