While not certain, this stratospheric warming pattern, and yes it is associated with climate change, might actually cause a cold start to spring. CWG does a good job describing this in layman's terms, but basically a stratospheric warming in the Arctic causes a disturbance in the Polar Vortex, which can push cold air southward. What's more, is that this air mass can also cause what's called the Greenland Blocking pattern, which is the source of some of the cold and rainy, dreary springs we often have. The high pressure builds along Greenland forcing cooler air towards the eastern US, and the storm track as well (something like that). And this can last for weeks on end.

If this happens, and I suspect it might, people who think that 60s in February might mean 70s in March and 80s in April, you will be in for a nasty surprise of 48 degrees and rain for weeks on end. Even worse, the poor plants. If the polar vortex breaks enough, it can send frigid cold snaps our way. This is bad, because the mild winter we have has fooled blossoming plants into thinking it's April. We have Cherry Blossoms already budding. When blossoming plants are at this vulnerable stage, one cold snap can kill them off.

Winter is supposed to bring sustained hard freezes which essentially hit a reset button for vegetation, and then they are supposed to awaken gradually in March and April. When you have them come out in February, that messes everything up. [/quote]
