The “SoCal RASP” link is currently only pointed to SoCal Windgrams. Is there a new RASP model as well? Here is the older example: http://www.soaringpredictor.info/rasptable/RASPtable.html.
The really simple SoaringPredictor graphs reportedly gave a good indication of the timing for wind direction shift at Marshall/Crestline. Is this of any value? Example: http://www.soaringpredictor.info/scal/SouthCalPredictor.htm
