Anybody know anything about very late stratospheric warming events?

An April stratospheric warming is forecast by both the GFS/ECMWF-- I know what these do in the winter, usually, but

in the spring? Is there the same connectivity and breakdown of the polar vortex in the spring? We have had such a

positive AO that there is some thought this could preview a negative AO in a few weeks. This is beyond my knowledge

base and I was hoping that someone on here could share some useful information.. thanks ahead of time!

gil I read it's called the 'final' warming when the stratospheric circulation transitions from its winter state to its summer state (zonal wind reverses). The mean date is April 15 but can occur as early as mid March and as late as mid May. Early final warmings tend to have a more -NAO during April than late final warmings.
