Looks like the worst is yet to come. Very wet and likely disruption expected to anyone travelling early tomorrow morning.

Does anyone know what these lines in the rain are about?

Gravity waves, potentially

Gravity waves (Undular Bores) often show up well in radar & satellite imagery. They can trigger showers & thunderstorms, or even interact with supercells.

Wind has got up.....again. I'm not sure if we will get a squall line like we got last Sunday

 

[ancientsolar]

Squall hasn't arrived yet in SE wales but I can see it on the way,. wind is easily as strong as last weekend.. may'be stronger

That doesn't surprise me as it's the highest airport in England.

Have had many happy landings in worse at LBA!

[ancientsolar]

Thunderstorm in the N.E .. wow that lit up quick

[Gray-Wolf]

Just copped for a 'mini squall line' and it was fierce!

If this continues to develop as it heads south some folk will have issues with both rainfall and wind

Be safe people!

EDIT: Yup , the NE leg of the squall has turned electric!

I would be surprised if you didn't hear any thunder, the squall has developed well and is dropping some lightning.

If the models projecting high wind speeds end up being wrong again, then surely they can't be trusted in future situations. Serious doubts about their reliability.

So forecasts still 10-20 mph out in a lot of places. GFS not to be trusted it seems!

Gusts are really getting stronger all of a sudden in Bexhill...

[toggerob]

Driving rain and gusts lashing against the window outside here, more rain to come overnight which is now showing on radar to the south of Ireland.

[Josh Rubio]

Very windy here in Nuneaton. Not much in the way of rain but the gusts are making the train sway whilst stationary...

[Ryukai]

Raggedy end of the squall line just hitting here now, piddling down a right ol'storm outside.  For some reason the temps shooting up as well :s up to 12C now o_O

There's a new splodge of rain coming across SE Ireland now.

[Paul]

UKV 15z run showing there's plenty more rain to come across England,  Wales and western Scotland tonight and into tomorrow. 

Rain totals from1500 this pm to tomorrow at 1500 (so some of this rain has already fallen, but still lots to fall which hasn't yet). 

[Atmogenic]

First ever time i've actually seen hail on the radar, and i've been here for quite some time.

[East_England_Stormchaser91]

On holiday in Whitby and as luck would have me, my eyes weren’t kidding me! At least 2 big flashes off to the North. No thunder heard due to the screaming wind. Really packing a punch now!

We upgraded the precip type detection last Spring, and part of that really improved the detection of hail  

[ancientsolar]

the BBC keep showing the rain over SW UK overnight almost like a double squall line,., I wonder if that means we could see a few strikes of lightning over night o,o would be pretty awesome.. though not something I typically see in February ,. 

Then tomorrow looks like colder air moving South... possibly thundery squall showers with hail on a lessening wind

Low tide was around 17:00 so still along way from high tide, yet sprat from waves going over the light house at Porthcawl

Wow warm fronts do not normally squall, this storm is interesting at least.
