According to one of Dr Jeff Masters blog there is a small possibility that La Ninia could be completely dissipated by summer. With the small possibility of El Ninio setting in by fall....Only 2 computer models showed that at the time.I dont know what has changed since then
La Nina is beginning to weaken as the SST's are slowly increasing and the Climate Prediction Center's models (most of them) are trending toward a transition from La Nina to ENSO neutral conditions by summer.
Thank God, I hope we'll start shifting into a wetter pattern this Spring. Were already in a Level 1 drought, I don't want it to get worse.
Well, my experience has been that when La Nina is in a weakening phase during the spring, we tend to have an active severe weather season. This was the case during the La Nina springs of 1989, 2000 and 2008.
I can certainly testify to 2008 being
VERY active. It's not often you get hit by a strong EF2 tornado and barely miss getting hit again the following day. The most active period imo was from February to May. I have never been under so many Tornado Warnings, Severe Thunderstorm Warnings, and FLash Flood Warnings, a couple of times all at once in my entire life. February 2009 started off on a similar pace, but the following months weren't as bad except April 2009.
