There are many different varieties of flowering Prunus trees and they flower at different times, quite a few in mid- to late winter. They're not easy to fool.

The jet stream is having a meridional winter, so it's blowing alternately warm and cold here. When it's mild it's wet. At the moment we have a northerly burst, but it probably won't last. We have a lazy wind (it goes straight through you instead of going round you).
