Apart from the routine Flight Operations that we support at the Flight Service Bureau, we spend a fair bit of time building new things.  Much of time, those things involve maps, and so we keep our eyes out for new ideas … and we especially liked this graphic presentation of US Winter Storm Jonas at the end of January 2016.

We took the original and slowed it down a little, but what you’ll see here is forecast data from NOAA’s High Resolution Rapid Refresh Model to animate the storm’s arrival in the Mid-Atlantic. The map shows water equivalent accumulated snow depth, or WEASD, which we can think of as the volume of water contained in the snow on the ground.
