Here it was 2010. Jan 1 thru May 5 averaged +6.2, capped by those first 5 May days with highs averaging 78°. Leaf out was at least 3 weeks ahead of usual, then May 11-13 had lows of 22/26/25. I'd not planted anything yet, so the garden was safe, but new growth on ash, oak, apple and some maples was fried - trees had to set new buds and start over. It was the 2nd year in 3 that we had about zero from our 3 apple trees. (In 2008 a cedar harvest across the road had attracted dozens of deer. When that cafeteria closed in late Feb, all the critters came to my place and with 40"+ of solid pack to elevate them, they trimmed essentially every bud.)
