Archie wrote Or, someone else, somewhere else has the same observation
or experience
where a tree is in bloom and flowering at this moment in time. I
suppose plants in greenhouses can be tricked into blooming out of
season. We had a cold snap a few weeks ago and now are above normal
temperature which may have tricked the crabapple into blooming.

That is probably exactly what happened. We see it frequently in Callery
pear here in Texas.
