I hate to be the party pooper here, but the snow conditions advantage is decisively with the West from mid-March onwards. There's a long list of mountains still enjoying midwinter conditions at that time. It's actually the most reliable part of the season at Mammoth, Mt. Bachelor and in much of Colorado. <BR> <BR>Weather records show that rain and thaw incidence in the Northeast increases sharply in March/April. Fresh snowfall often does stay strong through the end of March, as memorialized on this site in 2001. So the probability of excellent conditions is not that different from midwinter. But the chance of really crappy conditions is much higher. <BR> <BR>I have often noted that the East vs. West equation does vary by time of year, and this season is a good example of the East being favored over many western regions in early season due to colder weather and more comprehensive snowmaking. But in the late season the odds are stacked very much the other way. <BR> <BR>Ironically my first extensive ski trip east will be this upcoming March 16-23 for a ski journalist convention in Quebec.
