Jeff, I've always used the ET correction factor to predict the ET based on the new weather conditions. The ET corrected to standard conditions should be the same from day to day assuming proper jetting, good track conditions and no configuration changes. If you take the corrected ET and divide it by the current correction factor you will get the ET prediction. It has worked for me to +/- .001 secs. I'm assuming your weather station gives you the correction factor, i.e. the number that the actual ET is multiplied by to get the corrected ET.
