Going on 1882/3 which has been a fair guide:
cold March possibly top ten past 100yrs
I based this on solar cycle 12 some 130 years ago [charts to be added];
EWP, 8 1883(March) A ‘normal’ start to the month (first five days), but as the northerly airstream/[ex-Arctic] set in on the 5th/6th (see below), the weather turned dramatically colder. There were frequent severe frosts, with snow & hail reported throughout the month accompanied by strong gales (occasional further severe gales/see below, especially around the 10th/11th). Eventually, this March, with a CET value of 1.9degC (anomaly ~ -3C) turned out to be in the ‘top 5’ coldest such-named months in the series (from 1659).6th: Northerly gales (F9, isolated F10 / squally) northern half of the British Isles. 23 fishing smacks from Hull were lost, with 135 crew-members dead. Over 70 other vessels were damaged. There was also a severe snowstorm over parts of Scotland (presumably north & east) as the cold air set in. Booty
Another cold March occured 66 years ago in the winter of 1947. [charts to be added]
This is what the ECMWF has for the week ahead. No doubt it will change as will the current Met Office warnings.
