Not great news for people wanting maple syrup, but good news for me. Sap run weather is freeze at night, 35-40 sunny in day. Once I tap, the tree will slow in 5 weeks and heal and stop at 6. This gives me time to plan. If a season lasts 7 weeks, I want tapped during the best 4. If I tapped 10 days ago for a small 1 day run, I would've lost 2.5 weeks of an open tap until next warmup, losing part of my season.
