I think its downhill from here. If it stays zonal there is still little mild air about. 

Not a lot of change from Yesterday ...

Can that anomaly be right? It was 5.4C to the 12th with an anomaly of 1.2C, and now the CET figure has gone down 0.1C but the anomaly is 0.7C higher? 

OK I have just checked and the anomaly is 1.3C (I thinbk you read from the January column!)

Still odd though that the CET goes DOWN 0.1C but the anomaly goes UP 0.1C! That implies that the average for Feb 1-12th is 0.2C higher than the average for Feb 1-13th!

If you look at the yearly moving CET on the right of that Met page, it does show a quite steep dip in yearly CET around this time. It might be enough to answer your query

The Feb dip roughly coincides with the Buchan cold spell 7-14th Feb.

The difference is in fact only 0.1C but yes the average goes down significantly in mid Feb. Bear in mind this data is the 1961-1990 mean.

Using the 1961-1990 data the period from 13 to 18 Feb is easily the coldest of the winter and the only period when the 30 year mean falls below 3C. The data for each day are as follows:

13 Feb 3.1C
14 Feb 2.5C
15 Feb 2.2C
16 Feb 2.4C
17 Feb 2.8C
18 Feb 2.9C

So that anomaly will keep shifting quite a bit in the next few days.

The dip in temperature is less pronounced in the 1971-2000 mean but the period from 14-16 Feb is still easily the coldest of the winter.

Even the 1981-2010 data shows 14-18 Feb as generally the coldest period of the winter although there is one outlier as the 7th January is the second coldest day in that series.

Great post - Any idea of the rest of the month Simon. What do you think - mild or colder.

Very much on the mild side Gavin. Latest output this morning supports a CET for the second half of February of 7C. That would push the overall mean for the month to just above 6C.

If that verifies the CET for the winter as a whole would finish at just about exactly 6C which is 1.5C above the 1971-2000 mean.

Odds on now for the warmest winter since 2006/7.

The winter CET has only exceeded 6C on six occasions since 1900 with all bar one of them since 1975.

Prior to 1900 the winter CET exceeded 6C on five occasions.

So this winter could be the 12th warmest on record in the CET series.
