Weather Model Fantasy Land?

Posted: 08 Dec 2021 05:32 AM

After an expected winter storm that will bring accumulating snowfall over northwestern Iowa later this week, a major temperature warm up is expected next week. Weather forecasters are already buzzing with how warm temperatures are predicted by models like the NWS Global Forecast System (GFS). The featured map is a forecast for *next* Wednesday afternoon with much of Iowa in the 65 to 75 degree range. If this would verify, it would represent a number of new month of December records for high temperature over Iowa! Of course, many consider maps like these "model fantasy land" as it is a 189 hour forecast!
