02/03/18 - Stratosphere Update...

Here's a look at the current and the 8 day stratosphere forecast by both major models. These are at 10 hPa, 30 hPa, and 50 hPa levels. It's looking pretty certain we will see this split, and if so, it may make for a very lively end to the winter season. The last event we had was in January 2013 and before that, February and March of 2010.

Why is 0 a threshold? Or are you joking? I mean we are seeing over +25C anomalies. pic.twitter.com/feF3gUopcP
