Dr Roy Spencer has posted a map of the global temperatures in the
lower troposphere measured by satellite he
http://www.drroyspencer.com/2010/02/...mperature-map/
It shows a cold USA and Europe but a warm Canada and Arctic.

I thought that the warm Arctic might be causing the cold Europe, but
could not see how.

He has also included a map from the previous El Nino which is similar
to this one, so it seems that the current El Nino is causing the warm
Arctic and cold Europe! I think when El Nino peaks (Jan = yes, Apr =
no) may be a crucial factor in determining whether we get snow.
