You can leave the winter jacket in the closet for today at least as 2004 is going out on a warm note. While Iowa struggled to get the temperature above single digits just one week ago — National Weather Service meteorologist Craig Cogil says a shift in the jetstream is moving warm air in today. Cogil says that could lead to some record highs. He says it’s quite unusual to meet or exceed the record highs for this time of year. He says highs could be in the 60’s in central and southern Iowan and the high 50’s in northern Iowa. Cogill says enjoy it while you can. He says warmth like this doesn’t usually last very long. He says we will see a front move through later today (Thursday) with cooler temperatures but still warmer than normal for Friday. Cogill says 2005 will start with cooler weather. He says a storm system will be moving in on Saturday as well, and we could see some rain and possibly snow this weekend.
