I checked some of our earliest blooming cultivars today, but can't find any evidence of scaping.
I don't think it got quite as cold last night as was predicted. Weather Underground showed a reading of 25 about a mile down the road from us at 7am, but here on our hill, the faucet I left dripping was still dripping at 7 am (no ice at all). On the other hand, our nine mulberry trees, which were full of new growth and berries were devastated. Leaves and new berries burnt to a crisp, just like it happened to years ago.
I wonder why scientists haven't come up with a way to make trees remain dormant, once they go dormant naturally. That would be a godsend around here.
