Would it be worth it this year?
How much terrain will Winter Park, arapahoe, and loveland be likely to have open?
Yesterday was off the charts good at Vail, also. Bluebird, low crowds (for Vail), never got too hot so snow stayed sublime. No coverage issues whatsoever. 100% open. Headed to Winter Park Mary Jane today where virtually all the terrain is still open.
We skied Arapahoe Basin yesterday. It was 100% open with great snow. Last year I skied the first weekend in May there with great snow (it actually snowed a little almost every afternoon we were there) and again the first weekend in June with serious spring conditions. Mid April at the basin is one of my favorite times.
A-Basin in most year, and this year should be 100% open into early-May until full-on warm spring temps start to cause too much melt and water in the snowpack causes them to close a lot of the steeps.
Vail is staying open to the 17th, Breck to the 24th.
The next 2-3 weeks should be excellent spring skiing, with the occasional powder day possible. Coverage at the open resorts won't be an issue.
Beyond the 24th you're pretty much looking at A-basin, Loveland, and I think Winter Park is staying open.
Only Mary Jane is staying open at WP past the 24th. MJ is open 'til May 7th.
With mid-late April skiing, keep your options flexible depending on snowfall, terrain (some resorts start closings stuff due to lack of demand/staff) not necessarily snow conditions.
April storms tend to have higher snow levels but I wouldn't worry too much about rain. If you are looking at the national weather services, they stink at giving a good forecast. Its not uncommon for low elevation areas below 9000 ft to sometimes get rain in these spring storms if they come in warmer, but upper elevations will be getting snow.
