There is a surface low in the vicinity of Southampton at the moment (~1001mb), tracking northeast behind the main convection and is expected to slowly deepen as it moves towards East Anglia this evening and tonight - primarily driven by divergence aloft. 

Probably not the best source, but Weather.com has it weakening and breaking up. Where have you seen this?

Absolutely mad driving through the new forest. 

Stunning fast moving motion on the lower levels and insane rain.

Pulled over and caught a funnel but pictures not great. 

Was spinning like a top

Then pulled over and got an after shot and waved good bye

Various model output suggests the surface low will slowly deepen over the coming 12 hours, for example the 12z ARPEGE has central pressure 1001mb at 18z, falling to 1000mb at 21z, 998mb at 00z, 997mb at 03z and 996mb at 06z

I'm a complete amateur so forgive a potentially stupid question;

Low pressure obviously = wind, so presumably even if the rain breaks up it's going to get pretty blowy?

Depends on the pressure gradient - if the low is fairly slack, then light and variable winds cause areas of convergence that helps aid showers/thunderstorms to develop (assuming other ingredients are in place). If there is a tight pressure gradient, then you'll get strong winds. Potential for gusts 40-50mph along the south coast this evening on the south side of this low, but in general strong winds inland are not really expected tonight (aside from the convective gust component associated with thunderstorms)

Some charts from my weather station, showing the moment that torrential rain arrived:

I did a short video too. Excuse the focusing, I was behind glass so it was trying to focus on rain hitting it.

I wouldn't worry about watering your flowers for a while.

Wind changed direction in that video, rather strange but cool!

Strange weather here in Southend.

 

The radar shows heavy rain over Southend yet in my part of the town - Southend - Shoebury, there isn't any rain falling at all. I wonder if the stiff easterly wind is keeping it away.
