Interesting 1st half......I cor wait for the 2nd to start
quite impressed by the light pollution filter
I've been thinking about picking up a filter, how are you finding it? I can usually process a lot of the LP out with Photoshop but anything that can be done at capture time is appealing.

Couldn't see that faint display over this way and it was very clear. I'll be staying up to see if they appear for the pre-dawn show though...

cracking pic, proper camera? or phone?
Thanks mate, my Canon 90D.

Ha, I was out doing the same as it goes. I finished taking my milky way shots about 1:15am and turned back North to see that all too familiar glow, lucky really as I was about to head home.

Not sure if that previous pic posted properly or not but here is another one anyway

Yep camera is picking these up nicely

Pretty sure these are visible to my North now, I have a rather annoying strip of low cloud obscuring them but there is something bright behind that for sure.

Same here, I like how there is not a cloud all day long...until about 8pm, then its all low cloud on the Northern horizon. I tried again at 2:30 but absolutely nothing at that time.

Well done guys. I have been out most nights this week hoping to catch them again...and then last night was too cloudy over this way

Nice pics everyone! Gave up and went to bed too early didn't I. The tears are proper stinging today.

You can tell its not Wickford because it actually has something to look at That was Hullbridge, just a bit past The Smugglers Den.
Where was your windmill shot? I struggle to find anything North facing with a clear horizon around here.

Same as @mushymanrob, I thought the early showing was a good sign but they did fade rapidly before 11PM. Checked again at 2/3am but nothing.
These two shots were at about 10:30PM, looking North/North-East I think. Happy enough after a week of cloudy skies though.

This image was taken just after 11pm and I didn't expect to see anything that good.
I need to scout out another location during the daytime though

Visible to my North West now, shame there is some low cloud in the way but these are pretty bright tonight.

Lol I was going to go to the road that cuts across Hanningfield Reservoir to the South looking north so we might have been 2 lonely cars snapping away but went for the closer option.
Great Shot Dan
I like the reflections in this one below as well - Seems SE Essex was well placed for this event being so far south at 50.8N
Nice work mate. I couldn't really get any reflections I was happy with. That was the quietest I've ever know that East-West road along the reservoir, well that is apart from the geese who did their best to scare the **** out of me every 30 seconds.

My second shot of the night, this time from across Hanningfield Reservoir, somewhere between 2 and 3am. Didn't look as bright to me as the earlier showing but seemed much wider across the horizon - I was running on fumes by then though. Yes big thanks to @Arnie Pie for keeping us all updated.

I pretty much crapped out every time I tried to capture these last year but tonight I finally managed it. This was looking NNE about 11PM. Shame about the foreground but that will do for now

Can anyone recommend a good place to find UK Theta-e, Streamlines (convergence and divergence) maps? Lightning Wizard convective maps are really good, but a higher resolution for the UK would be really useful! Thanks!
Theta-e (850hPa) output from a six member 4km wrf ensemble
sref.io : short range ensemble forecast
SREF.IOA short range WRF physics ensemble with six concurrent members producing output for the UK & IrelandI'm not plotting convergence and divergence currently but could always add that to the list

Bumped into your mate Pete Scott at Stansted last night, he showed me a nice spot (thanks again, Pete) for shooting CG's against the ATC tower - nothing hit to our disappointment
Still, nice to blow the dust off the camera and see some UK lightning.Not the best pic (but best of the night), I'm a bit rusty this year...

Yep, tis important to bear in mind with these various flavours of the NMM etc is that there are a multitude of physics options and params within the model that can be changed/tuned + differences in the initial conditions, model used etc etc.
Hi Paul
Is your 4km running a CU scheme, and is it nested or a straight 4km grid?
-
Storm Relivity Helicity, basically higher chance for Supercells.
Some of the forecast soundings do show some impressive SRH values with some rather large looping hodographs. I'm assuming this is due to the low level south-easterly flow (possibly 35kts at 925mb on some output) with veering winds above. Its almost a shame, as the boundary layer looks quite stable and with these storms rooted above, but a surface based storm in that environment could be very interesting.

Right...I can't work this out
Below are two charts from (I presume) the same 00z WRF-NMM 2KM model
The first is the UK map - pony for the SE/Home Counties I'm sure you would agree
When one looks at the same charts for France, for the same time (0300)...completely different
Make of that what you will...I'm sure there's an explanation...yet to think of one though! Latter option please
They could well be two different model grids placed over different geographic regions, rather than one big 2KM grid. Probably a good example of how these models are quite sensitive to the initial conditions they are initialised with and their model configuration, physics, domain sizes etc.

Now GFS has abandoned me ....noooooooooooo!!!!
Modellzentrale's 4KM looks better for the south east, though if you follow that model closely it can get a little excitable with convection at times. Doesn't mean its necessarily wrong this time, but I guess we will find out later!
The ManUniCast model would be worth checking when it rolls out.
Still, nice to blow the dust off the camera and see some UK lightning.

Nothing wrong with those! I gave up, I could just about make them out but the fog ruined it
