Storm video from the other day although the audio was the main goal

It's May and nearly time for NLCs to reappear once again. A few helpful links I've collated: IAP MLS temperature data at 54.1N - https://alomar.andoyaspace.no/rmrlidar/html/auramls/index.html Mesopause temperature over the UK - https://www.geos.ed.ac.uk/~hcp/meso_ts/ MAARSY Mesosphere radar - https://www.iap-kborn.de/en/research/department-radar-remote-sensing/current-radar-observations/maarsy-mesosphere/ OSWIN Mesophere radar - https://www.iap-kborn.de/en/research/department-radar-remote-sensing/current-radar-observations/oswin-mesosphere/ NLC Camera Map that I made - https://www.google.com/maps/d/u/1/edit?mid=1qhdX7mj7eciDYjZF61LU9zYDCNwdDzA&usp=sharing IAP NLC camera network - https://www.iap-kborn.de/en/research/department-optical-soundings-and-sounding-rockets/instruments-and-models/nlc-cameras/overview/ German NLC forum - https://forum.meteoros.de/viewforum.php?f=34 German NLC website with lots of information/links and previous sightings to 1885 - http://www.leuchtende-nachtwolken.info/ German website with information about previous NLC sightings in Rostock, Germany & links - https://3sky.de/ Czech website for monitoring NLCs with previous sightings - http://ukazy.astro.cz/nlc-monitor.php NLC visibility map, allows you to put in long/lat for possible altitudes of NLCs at certain times of day - http://www.theusner.eu/terra/nlc/nlc_vis.php

Lightning shots from yesterday

The best lightning shots I have taken ever

Me & angel fiance Can't remember the last time I dodged storms and got blinded by fork lightning and CGs!

Massively active storms here along the Estuary Seen CGs, fork lightning and had nearly continuous thunder for nearly an hour from half 11 to quarter past 12 One off the camera but there's many to sift through

Flash

Seen a few flashes on this camera from the Belgian cell

Elevated storm in the Theta-E plume, may be one to watch for Essex

From the storms in eastern France

Alderc 2.0 Can confirm it’s very muggy around here

lol AROME still going mad, 3.2k CAPE over the Estuary

AROME with a casual 2200 J/kg over Ramsgate

reef I've noticed some of these adjustments in some of the data for Manston from https://www.metoffice.gov.uk/pub/data/weather/uk/climate/stationdata/manstondata.txt although not entirely sure when it stopped. July 2006 has a value of 350.1 hours for its K/Z sensor although the raw data from MIDAS seems to suggest it was 316.9 hours which is a pretty drastic difference. It makes it hard to compare values when there seems to have been some adjustment that isn't clearly stated, can only presume it was to continue the consistency of one instrument being used but this correction isn't being done correctly so

SunSean Lol yeah, still awaiting the 2000-hour mark for a year that Zeebrugge in nearby Belgium seems to get fairly consistently in the last few years.

SunSean I hadn't realised the difference between Manston & Shoeburyness was that stark! I'd have thought Shoeburyness would have surpassed Manston as we begin to head into late spring and into the summer months

Today does seem to hold some merit at least for the far SE for the potential of some thundery activity into the evening. Shear profiles from AROME do seem to suggest the possibility of organised convection developing in the far SE with a low chance of any storm developing supercellular characteristics with it. It seems more likely that this will happen in northern France due to the 1500 J/kg of MUCAPE being available vs the 600/700 available in the SE. The abundance of potential convection developing in the SE does make me feel it's pretty unlikely unless one of the storms scoops up everything left in its environment. AROME did seem to play with the idea of a supercell developing in northern France on its 12z run yesterday with a storm that deviated to the right of its mean wind. Theta-E values are also highest in the far SE which seems to indicate to me at least that there is where most of the thundery activity will be even if convection does develop further west. All that being said however I still wouldn't put the chances of any thunderstorms developing at anything other than a slight chance considering conditions look MUCH better across the pond in France.

Showers galore later based on AROME

Sprites Sadly not this was just one of the Weather Watcher images I found searching through - bloody wish I was though

My report for Church Stowe WWW.BBC.CO.UK Church Stowe, Northamptonshire Largest hail I've seen for March

Dxnielwashere The Tornado and Storm Research Organisation (TORRO) WWW.TORRO.ORG.UK TORRO is a privately-supported research body specialising in severe convective weather in Britain and Ireland You can fill in a report here

7th - 14th August had 120.7 hours at Shoeburyness, an average of 13.4 hours per day. One of the best periods of weather that I can remember recently as well as being very warm, avg max here in Herne Bay was 24.6C. A selection of some of the pictures I took during that period are here.

@Eagle Eye That very strong Pacific jet is certainly a show for how strong the +MT event currently is Let's just hope MJO passes through the maritime barrier and doesn't 'konk' out

I was wondering where the ice warning was!
