It could well be the wettest January on Met Office record - previously set in 1948 when 176.8mm fell across England and Wales.
Around 163mm of rain had fallen by last night and with another active system bringing more substantial rain on Friday and into Friday night, that record could well be exceeded.
This would make it the wettest January since Met Office records began in 1910 - and since historic weather records started way back in 1766!
A week into the new year, some places had already received more than an entire month's average rainfall in just a matter of days.
Parts of southern England have already seen double the average rainfall amounts for the whole month.
There has been a stark north to south contrast too - with far more rainfall than average collected in the south of England compared to the north of Scotland.
Previous wet Januarys include 1988 (169mm) and 1995 (162.6mm).
This month has also been unseasonably mild - mild air can hold more moisture.
