I'm still lamenting the fact that the Naval Research Laboratory has pulled the plug from the PIPS 2.0 website. Sure, they were having trouble with their ice thickness maps, but I had hoped they would leave the ice displacement maps in place until the end of this melting season. It was a tremendous help last year in determining whether the fun was over or not. They have new maps out on their ACNFS website, but somehow it's not giving me the same reliable info as the previous, much simpler version. And the AARI ice drift map is only updated on Thursdays for the entire week, which makes it less reliable as the days go by.
Luckily, Arctic.io has been tinkering to find a solution after Robert Grumbine linked to a data set in one of the comment sections here (can't remember which one). He converted the numbers to a map with vectors that can be laid over his Arctic Mosaic map. He made another overlay that consists of the DMI SST map we know from the Daily Graphs page. Together it looks something like this:
As it says in Arctic.io's post:
The drift forecast model visualized here as an overlay on the Arctic mosaic implements this drift law. The model is rather simple, nevertheless the results are pretty good. It provides a forecast of 16 days, shown on the map are the 72 hours forecast vectors.
The National Weather Service's National Centers For Environmental Prediction's Environmental Modeling Center runs this model for decades and it is used by the Anchorage Weather Service Forecast Ofﬁce and the National Ice Center (NIC).
The relevant science and math of the drift model is explained in this paper: Virtual Floe Ice Drift Forecast Model Intercomparison. I’d like to thank R. Grumbine for his help clearing out some roadblocks during the course of this project.

This could come in very handy in those last two weeks of the melting season. Thanks, Arctic.io!
Update: Arctic.io has told me that you can press the buttons 1 to 6 to get different forecasts for difference days (1 for 1d, 2 for 2d, etc...). Pressing 0 even gets you an animation.
