Boulder averages a foot of snow in April. Syracuse averages about 4 inches. Throw Title IX into the mix, and it's easy to see why SU and CU don't play baseball.
Madison gets less snow in April (2.6 inches), but that's still nearly double the April average in South Bend (which has a higher annual average due to the lake effect, but lower average in April because it's not as cold).
.....And there was like 4 inches of snow ....Buffalo gets the wrap
but Syracuse is the snow capital of US....
Though baseball seems like a rather cheap sport to play, quite honestly: there are many teams all over the place so little travel is required if not desired, and it's only ~12 scholarships.
This article from 2009 was written about trying to bring it back but it does refer to "balancing male/female scholarships" as a reason it was dropped.
And it's more expensive now than it used to be. For one thing, to be reasonably competitive, a northern school has to take multiple road trips to the deep South or the West Coast in February and March. ND took far fewer of those trips until the revival of the baseball program in the 1990s.
