raz.org.rain It is an anomaly, but with 19c in the southern part of the Benelux, I guess it is a record for this time of the year. In the summer it would mean, 30c for sure.

Hi guys, you miss for the a big part, a portion of extreme warm air. Anomaly 850 hPa is 20c in some places!

Thanks. This one is quite interesting too https://www.rmets.org/sites/default/files/hist16.pdf 1809

Through archaeological and historical evidence, this book investigates how these sudden and unpredictable events affected British medieval populations (AD 1000-1500). Medieval society understood disasters in a practical sense and took steps to minimise risk by constructing flood defences and reinforcing structures damaged by storms. At the same time, natural hazards were widely interpreted through a framework of religious and superstitious beliefs and a wide variety of measures were followed to secure protection against the dangers of the natural world. Disasters, therefore, were interpreted through a duality of understanding in which their occurrence could be the result of spiritual or superstitious triggers but practical solutions were a key component in mitigating their tangible impacts. In evaluating this duality, this book focuses on specific case studies and considers both their diverse historical contexts as well as their consequences for society against the backdrop of significant demographic and climatic change—as a result of the Black Death and the transition to the Little Ice Age.

johncam No I have not.

Temperature chart for this winter.

Scott Ingham 12th of february

A split SSW.

AO- In Dutch we say 'voorgeschiedenis'. The setting before we get an easterly is indeed not good for cold later on.

Average at 240h. EC. Impressive.

How is it possible...

I think it is time to watch the stratosphere closely. GFS0h delivers a split, combine this with a blocking in NW-Europe and you get downwelling till the end of march, start of april. https://wcd.copernicus.org/articles/1/373/2020/

That is the air pressure anomaly

For the week of 19th February, an increased warming compared with earlier this week.

The output for week 19th of february. Today there is no cold anomaly for NW- & Central Europe.

LRD indeed, a couple of runs with cold anomaly for NW-Europe.

We must be incredible unlucky if we don't get a couple of cold days in the coming weeks

Truly remarkable. The positive NAO regiem is falling back to a staggering low number at 20th of february in the ENS.

EC46 cold. Massive upgrade from a couple of days ago. A dip to 15 m/s. The border of a weak stratospheric polar vortex is 20 m/s.

Four models at 144h. I find it hard to tell which one is the best.

@BarnetBlizzard It has some credit, as EFC46 is hinting in this direction for some time.

UKMO, GFS & ECMWF at 168h (162H, GFS) GFS differs from the other two, especially around Iceland.

Well, the plume doesn't seem to indicate a cold period is coming soon.

Excellent EC46!

@Daniel* i agree with you. Together with GFS oper some days later, they seem to me excellent charts (besides far away)
