On 24-25 January, a storm system moved across the Southeastern U.S. producing widespread snow and ice accumulations. On the 23-24, it looked as if the storm would move out to sea without greatly effecting the eastern seaboard. However, the storm did turn northeastward and was a major snowstorm for the eastern population centers. The 2-day period has been divided into 3 hour intervals so that the animations will be managable by most computers.
Times appear on the lower bar of the satellite images.
The next 3 columns can be used to compare the divergence, vorticity and isotachs from the satellite analysis with the RUC-2 hourly analyses. In general, the RUC-2 wind fields contain more structure than the satellite winds because of the model's high resolution. Note the the guess fields are updated every 6 hours. In general, the satellite analysis contains more detailed structure than the model fields.
