There's a lot of talk about changes down the line and why this should happen etc...if after all that it's remains zonal, will people start to accept that there has been a significant change in our winter weather patterns ?

Can you post charts for mid Feb and March to back that up....................how can you make a comment like that ?


They see a lot more info than we do , the signs must still be there ?

We shouldn't forget that the models combined threatened a continuation of December's dross in the New Year; what followed wasn't a perfect cold spell, as another thread on here has made clear; but nor was it expected by the outputs.

I think there has been a significant change in weather patterns at mid latitudes in the last three decades. The absence of high level blocking to our north east in mid winter is, for me, the clearest indicator that something is different.

Go back to the 1920s and you may find a similar patternb, because our weather is infinitely variable. We have had snow droughts in earlier decades - the 1970s were not particularly notable for good winters, although the 1960s and early 1980s were. I am pretty sure we will get another decent winter before long, but whether that is in 2016-17 or 2017-18 or later, I shall leave up to the weather.


Yes, it is deeply frustrating, but that is the way it is. In 50 years, they will be able to look back and say more clearly whether there was a genuine pattern change in the current period or not.

The frequency of cold winters has clearly decreased, as it has almost everywhere in the world as the result of a general warming trend over the past 3+ decades (which is more pronounced in high latitudes than in mid-latitudes), but that's about it.

There have been marked changes no doubt, possibly due to natural variation or other factors.

On the cold chance side of things, at least GFS has stopped moving the strat warming back now and a minor one still due in the nearer time frame.  Poor output today though again it has to be said for cold weather fans.

Even at the end of the very cold winter of 2009/10 we had a snowfall on the 2nd March on frozen ground but it had melted by the evening despite a dry day and max of only 2c.


IMO we have one month of winter left max and it ain't looking good.

To re-iterate: latest GloSea5 ensembles have predominance of -ve temp anomalies after mid-Feb. Latest EC Monthly has neutral or -ve bias. Crucially, neither exhibit a +ve signal.

The north west coast of the USA and west coast of British Columbia have similar winter weather to the British Isles and if it wasn't for the Rockies that influence would extend some way further inland.  As it is the Great Continental Divide separates the west coast maritime climate from the continental climate that exists east of the mountains.


Weather in winter in North America is still influenced by the behaviour of the jet stream and the PV.  You haev only to contrast this winter to date with a couple of years ago when the PV dropped down into North America for a time.
