December 3, 2011 Snowfall: Forecast vs Observed


December 3, 2011: Snowfall Forecast vs Snowfall Observed


The attached image shows the forecast made on Wednesday, November 30 for the time period 72 hours later, Saturday December 3, 2011. The attached image also shows the satellite image from Sunday December 4, 2011.

There is a remarkable agreement between the forecast snow path and what was observed. Although there are a few clouds in the image, it was mostly clear across the region so that the fresh snow cover can be easily seen. Note the gray color where Lincoln is located. That is typical of urban areas where the streets and buildings will shed their snow cover and make the image darker than the surrounding snow covered rural areas. You can also see some unfrozen lakes as they are darker compared to the snow covered land.
