I'll go for a month in the same style as autmn 2019 and winter has been so far - constant downpours and rain and also cold

4.5°C, 550mm.

Record wettest March ever, massive flooding and people having to leave the country due to more than 60% of it becoming immersed under water.

Quick question (not sure right thread) Whats the mildest winter 3 months CET for DJF? Using the Netweather CET average should be 5.1c + 4.2c +4.2c = 13.5c /3 = 4.5c. So far we are at 6.37c + 6.89c +6.97c = 20.23c / 3 = 6.74c !   

Basically an Autumn!  

I feel we may have 'tipped' into a new era of climate change here I really hope we haven't. 

Just interested how this winter sits in the overall numbers. I can also see its been very wet!

6.0*C with 80mm rainfall please. Cheers.

A month that may start off chilly. A mixture of rain, sleet and snow in places. Warming up greatly beyond mid-March with lots of sunshine. An extremely intense hot plume from the South will then bring temperatures up to 29*C in places breaking down to some severe thunderstorms and a massive sudden undercut of freezing air dropping temperatures like a big rock. The torrential rain and hail accompanying these thunderstorms will become replaced by big, fat, snowflakes during the massive temperature drop. Final part of March becoming sunny and warm, again.

Tried to look at Decembers between 5.5 and 6.4C that had Januarys greater than 6C for a pattern, only to find 1736/7 was the only previous winter year in which it happened!

The Feb of that year was 4.2C while this year looks considerably higher.  the March was 6.1C so I'll go higher on that.

6.9C and 77mm for me please.
