Warm May?

May appears to be shaping as one of the warmest on record across eastern Australia. Surely that must presage a dreadful snow season? Well, no, not really; there’s very little correlation:


That shows the correlation of the season peak snow depths at Spencers Creek¹ since 1954 with the mean May temperature anomaly for the whole of Victoria.²  (The May 2014 Victorian temperature anomaly looks to be going to be about +2°C, or a little less.³)

We wouldn’t want this warm period to go on for too long though.
