My buddies and I are wanting to do a weekish-long trip at the end of April. I've hiked through the Presidentials a couple of times in the July-August timeframe, but I'm not familiar with spring weather in the Whites. I know the weather is always unpredictable up there, but what are the conditions like on average around the end of April and beginning of May? Is there a good chance there will still be a lot of snow and ice on the trails between Franconia and Pinkham Notches?
