There is a wealth of information on the ADDS testbed website that you may like for flight planning purposes.
wwwt.emc.ncep.noaa.gov/mmb/SREF_ … z_prb2.htm is a good example.
Then click on animate above the graphic. I love the flight restriction probability forecast, from LIFR to VFR and when you animate it, it shows the trends whether it be expanding area of LIFR or a frontal passage moving across.
