I was going to suggest a decent weather station, but Altronics beat me to it.. I have a Crew Chief Pro system in my trailer, and couldn't believe all the options available for predicting the weather, pertaining to throttle stop and ET predictions.. you will not be dis-satisfied making that move, if you haven't already..

I always looked at density altitude, (DA), while trying to dial, but learned that it is the formula that goes into arriving at the DA that is more important.. that being said, I'll tell you that grains of water and vapor pressure are pretty important.. the higher they go, the slower you go..
