In a word, no. Weather prediction is still as much art as science. But steady winds are not as bad as gusty winds, and crosswinds are not as good as those aligned with runways. Larger aircraft are less susceptible to these than smaller a/c; yesterday I flew around Northern California to do some jobs in a Beech KingAir C90 (turboprop twin engine) - perfect weather yesterday, but it wouldn't handle winds a 767 might be able to deal with, but can cope easily with stuff a Cessna 150 might not handle at all. But 40 - 60 kt gusts? Be prepared to make alternate plans - e.g. an earlier (assuming you can and there are seats) or delayed departure if you want to fly, IMO.
