An ancient image from 2017 representing my only capture of the phenomenon. The image is from a plane, looking directly to the north. You can 'see' the noctilucent clouds as a band of cirrus-like clouds above the horizon. Taken in June/July. It was really interesting, flying in the dark, watching the sun still shining over northern countries.
After trying and failing to get a decent timelapse, I went out to see if there were any more mammatus clouds, my house being right under the anvil of a storm. I looked out of a window pointing to the west and almost had a heart attack. It was the best funnel cloud I have ever SEEN, a grey finger pointing towards the earth from a deck of especially dark cloud. But, for once, even my speed was not enough to catch it. When I shifted location to get a better view, it had fallen apart. The tendrils r
Another shot of the anvil of a storm which sidetracked Cambridge today, containing mammatus clouds. I thought this was just great, until I looked out of my other window and practically had a heart attack...
Very windy today, a drizzle swept over Cambridge. Intense skies and thunderstorms, but everything stayed away. That I thought, until I looked out of the window. These are the most spectacular mammatus clouds I have ever seen, on par with ones earlier this year from a train going from Bristol.
For farmers and road users the numbers of deer can be a nuisance, but Roe Deer do have a certain graceful beauty.

The main Air Masses that affect the United Kingdom
Air Masses are defined as a large body of air (covering many thousands of square kilometers) which at any given level has almost uniform temperatures, lapse rates(see topic on this), and humidity.
Their Source Regions are large areas of the earth where air often stagnates for long periods. Examples of these are the Polar Regions, and the sub tropics. Air over any of these regions may stay for long periods and thus picks up the characte
There was already a guide written by me about UK thunderstorm set-ups, but it was done some 10+ years ago now and I've felt for a while that it needed a re-vamp and updating to make a more comprehensive guide to the processes that produce the various types of thunderstorms we see in the UK.
So here it is ... the Netweather guide to thunderstorms in the British Isles .... 15 pages long:

This is my revised version of the summer synoptics guide.
The standard summer synoptic setup
Traditionally, in summer, we have a strong Azores High out to the south-west, low pressure systems moving from west to east to the north of Britain, and westerly winds dominating, bringing cool cloudy weather and rain at times. Southern areas see the warmest and sunniest weather as they are closest to the influence of ridges from the Azores High.
Low pressure dominated scenarios
The Arctic Oscillation
Arctic Oscillation is an important lead on expected winter conditions in the Northern Hemisphere, loosely described as negative ( colder ) positive ( milder). The image below gives you a great contrast of a winter we will all easily recall with an extremely negative AO and a little further back a winter at the opposite end of the scale.
When considering the overall forecast for Winter it is important to note any variables which provide clues as to which
