Banding Snow

Snow totals tomorrow will vary from location to location.  Snow storms often have banding features, which are very recognizable when you look at radar, but very difficult to forecast in advance.  That is why there are always ranges given when forecasting snow.  As an example, the storm on Tuesday in some ways seemed to avoid Sioux Falls.  Only 3.5 was the official measurement from the storm, which was about one-half of the original expectation.  The official reading for that city is at the airport at the far north end of the city.   Yet in the far southern part of the Sioux Falls metro 6 to 7 inches was recorded.  Similar short range difference may be in our future tomorrow.
