I know all I do here is point to ACNFS, but its Archive of ice speed and drift includes a 5 day forecast, with NOGAPS atmospheric forcing, every day. The Aug 1st run isn't posted yet, so the last snapshot there now is 00Z (midnight UTC) on the 6th of August (from the July 31 run). The arrow tails are following streamlines. This may not be telling you anything new over, say, the ECMWF pressure forecast. Except that it is showing sea ice directly.
ACNFS is predicting increased ice drift through the Fram Strait this weekend. It was quite different this time last year

ACNFS provides a 5-day forecast. Its archive pages provide daily snapshots from each day's run for 3 days behind and 5 days ahead. ACNFS is using NOGAPS atmospheric forcing, so at best its forecast skill depends on NOGAPS. The arrows on the ice drift plot are following streamlines. The speed is color contoured, and the arrow lengths are also dependent on speed.
