The National Weather Service has issued a frost advisory for a large portion of the state, and parts of eastern Iowa are under a freeze warning. Meteorologist Mark Russell says the conditions are right for a chilly overnight.
Russell says a high pressure system is settling in, and the clear skies and dry conditions will lead to cooling. He says the northern half and eastern sections of the state will be the coldest, with temperatures easily falling into the low 30’s. Russell says those with flowers or vegetables should make plans to protect them. He says anybody with tender vegetation should cover them up tonight.
Russell says the near-freezing overnight shouldn’t last long. He says the high pressure will move off, and overnight lows by Sunday should be into the low 40’s. Russell says this is the time of year when Iowa sees a lot of ups and downs in temperatures. See if your county is in danger of frost or a freeze as the National Weather Service website.
Russell says the air masses from the north are getting much cooler, which continues to give us a big variation in the warm and cold temperatures. Russle says the frost is a little earlier than we normally see.
