Winter Storm: Dec. 7/8 Update #3

The morning GFS (12z) model forecast continues the trend to indicate significant snowfall accumulation across the plains states, similar to this mornings NAM model forecast.  Total snowfall accumulations of over a foot are likely across parts of Iowa, Minnesota, Wisconsin, and perhaps even Illinois and other adjacent areas.  Moderate snowfalls are occurring across the area, and accumulations nearing a half foot are already occurring over areas of southern Iowa and nearby areas.  Additional updates are likely later this afternoon as more details on accumulations are given, and if any road conditions warrant a quick update.
