In Virginia we had reasonably good luck with this cold snap. The coldest temp I measured was 24 degrees early Sunday morning. A number of my apricot blossoms will be fried, but even on that front I should have enough survive that I could still have some apricots this year.
The real worry is that we could easily have another frost between now and April that could do a large amount of damage, and there will be far more blossoms to injure if we have another cold snap.
