66.4 for the month so far. We have now has 18 consecutive days of measurable rainfall, and only had 1 dry day in the last 34.

3,6mm Yesterday. 0.3mm Today. Total for Mid January 67.8mm.

Here in Wareham,Dorset we are up to 125mm of rain so far! Thats 5ins in old money with more to come

This is the perfect winter,mild and wet

Total now states 71.mm.  ...

Only one public model seems to have a reasonable handle on the convection at the moment and that's WRF. Here's what it shows for 2pm today up until midnight:

http://modeles.meteociel.fr/modeles/wrfnmm/runs/2014011612/nmm-25-11-0.png?16-17

Around 10mm across much of the south.

24 hours later:

http://modeles.meteociel.fr/modeles/wrfnmm/runs/2014011612/nmm-25-35-0.png?16-17

30-40mm widely (still starting from 2pm today, that is) with locally up to 70mm...!

If WRF verifies, the Met Office will have failed to predict a very severe weather event. This is strange, given that their precipitation outlook charts show similar precipitation development to WRF.

While I feel WRF's 50mm+ projections must depend on an unusually extreme bout of convection, I wouldn't rule it out entirely, and even without it there could well be totals across the south of around 20-40mm for today and tomorrow combined.

In theory, that's going to send those river levels rising again. Where's the Met Office warning...?

This has caught me by surprise a bit. The radar has really come to life with some very heavy showers.

Edit: I see the WRF predicts upwards of 400mm of rain in one spot on the Ligurian coast over the next 72 hours!

NAE on the potential extreme rain event on Saturday

This one needs watching closely I think.

If it's still there tomorrow, I imagine warnings will fly for the locations affected - which GFS and NAE indicate will be somewhere around Devon, while WRF models less of a stalled situation, with the boundary progressing east more rapidly.

There seems to be scope for 40-50mm in the space of 12 hours somewhere if it runs across Devon, although I suspect the areas of higher ground there play a role in that.

A new record high for the river level at the Salisbury Bourne recording station.

Hardly surprising after over 140mm in the past 16 days and around 320mm in the past month (31 days).

That's the wettest monthly period I've recorded by some margin, beating what was about 250mm Nov-Dec 2009.

The Environment Agency has my local stretch of the Avon under a flood warning and talks of river levels rising in the next few days, yet the 3-day flood risk forecast states 'low risk'.

Go figure...

I've noticed in a recent accumulated rainfall data (past 12 hours) that North and West Kent had a very wet night with 10 mm to 30 mm of rain - yet here at this end I don't think we have even managed 1 mm (the ground is just about damp to the touch).
   Seems that the good ol' Harbour Rain Deflector is up and running again. This chart shows the effect very nicely: https://scontent-b-lhr.xx.fbcdn.net/hphotos-ash3/t1/1535692_10152136946291306_520477031_n.png Wish it has the same effect on strong winds, though.

As of now, the Winchester unofficial total is 158.2mm. Factor in the amount from 13th December this makes 321.3mm

This is biblical stuff which I haven't seen in any of my locations in my lifetime although I did live for many years in the drier part of Essex. 

A foot of rain in 36 days

The showers really chained last night, with some areas seeing a lot more than others within a relatively small region.

For example, Boscombe Down, north of my home location, saw just 2mm betwen midnight and 6am, while Thorney Island, near Portsmouth, saw 10mm. Hurn Airport, south of my home location saw 6mm.

My home location saw 7mm and to be honest I find Hurn's reading a bit on the low side based on the radar sequence for overnight, which shows hardly any let-off in the moderate to heavy rainfall during the 00-06UTC period.

Also, another river level record has fallen in my local area, with Ringwood Riverside Terrace at 1.26m as of 4am, putting it 0.06m above the previous record. It's probably risen a bit further since then. The flooding across the plains must be staggering... and I imagine Moors Valley is more or less un-traversable.

4.2mm Yesterday.. Total only reads 71.9mm.

for the foreseable by the looks of the latest models.

UK remains in the firing line of these atlantic troughs and the high to our east does not seem to have a chance.

Patchy drizzle here.

65mm for th emonth so far, Average here is about 75mm so it seems certain to be above that.
On average, January is the usually the last wet month here until June.
Any of the spring months can be wet, but are often enough rather dry so the average for each of the next four months is around 50mm 

By June convection events can give large totals in a short time.
Our wettest month is August (av. 100mm) for the same reason.
