Seems like Canada, particularly central and western Canada has had a good winter this season. Like wise NE and Central Asia. Less so Europe, milded for the most part there.

That cold outbreak in the Central US was a good one. It seems temps in the prarie states of Canada have been consistently low since then. I think I even recall seeing a -40C on the WZ forecast for Saskatoon, not sure if it came off? Pretty sure Yellowknife further north got there. Be awesome if other countries has organisations that made it as simple and easy to access data as our BOM.

Appears to be a pretty good late winter event for Vancouver over the last fortnight or so.

For the US as a whole, it was a slightly warmer than average winter; near to slightly below average in north-central areas (Montana and North Dakota still came in close to average despite an exceptionally cold February), near average in much of the rest of the western half, and mild in the east (very mild in the southeast). Main standout was actually the precipitation - it was the wettest winter on record for the US (48 states). Alaska was much warmer than usual - a common occurrence in recent years - though not record-breaking. Haven't seen Canada-wide figures, but most of the southern provinces seem to be close to average - in the west, a cold February offset a mild December/January.

It's relatively easy to get site-level information for Canada, but very hard to get things like regional maps.

Yeah I noticed Anchorage didnít really seem particularly cold most of the time I checked. Was sort of floating around zero and only saw it around the -11C to -5C range a few times. Sad to think whatís more than likely going on with warm winters of recent years.

I wonder how the Arctic sea ice extent is going. Should be just about at itís peak.

http://nsidc.org/arcticseaicenews/ is your friend. Looks like low overall but not as low as the last couple of winters over the Arctic as a whole, but exceptionally low in the Bering Sea.

The December-February period was the 4th warmest on record globally according to NOAA (https://www.ncdc.noaa.gov/sotc/global/201902) - 6th warmest winter for the northern hemisphere (10th for land areas), 2nd warmest summer for the southern. 2013-14 was the last winter which was colder for northern hemisphere land areas.

Yeah I had a look at that site Blair. Was pleased to see that the ice extent wasnít horrrendously low. I suppose focussing on the extent is only one measure. Thinckness would be a huge factor as to how rapidly the ice breaks up and melts as the NH moves into spring and summer.
I wonder if someone has graphed the differnce between winter and summer ice extent and used that as another way of identifying change in the Arctic environment? I would think the difference as a ratio between summer and winter ice extent would be increasing.
