My brother, who lives in southwest France wrote to me the other day about a strange experience. So here’s his words and your thoughts will be appreciated.
“It was getting on for 7pm (on 30th March) when I drove home from town (Riberac) and still nicely light with some weak sun shining from the west (where else!) As I drove out of town I was heading west for five minutes and then turned 90° in a southerly direction directly towards home. (As I've often mentioned) I live literally on top of a hill which is surrounded by valleys and a very large flat agricultural area which spreads away towards the north and the west. Well, it was through this flat area that I was now travelling. At the moment there's very little growing in the fields but they have all been ploughed so it appears to be quite an immense area and you can see for miles.
At first I didn't notice but soon realised that, although the sky all around and down to the horizons was light with the sunlight reflecting on distant white clouds, overhead was the most enormous black cloud, miles bigger even than a Vogon Constructor Fleet ship, that seemed to be almost stationary. The sort of black that could not even reflect light back. I was so amazed by this sight that I actually stopped my van and just sat there marvelling at this 'object'. It had also started to rain, great big blobs of the stuff not at all like raindrops and that reminded me that Meteo France had very recently mentioned the possibility of 'orage' which is thunderstorm and possibly hail.
When I returned home I checked on the weather radar to see if there was any rain due. There wasn't and there was only one area of rain on the map which was more or less round and corresponded exactly with the cloud I had watched. So I pulled out on the radar and there wasn't another area of rain in France apart from along the North coast and a couple of small patches towards Paris.”
So what caused that small ‘blob’ of cloud and rain? It was divorced from all other things such as fronts, depressions or even hills. I guess that the low sun added to the depth and darkness of the cloud, by the way. Personally I suggest that it was a small eddy in the pressure that created a mini-depression but I’d be pleased to hear someone else’s thought – especially someone who knows about weather.
PS Sorry his screenshots come from another weather site!
I am an amature DJ and also a keen weather enthusiast and been a member on here for a little while now and so pleased i found this site as i have learned so much more about the wonderful weather we have. So in return i have decided to put my mixing skills to the test and do a special weather related mix...
So if you can please leave any songs you can think of that are related to the weather be it by song title or song /artist themselves. I will choose the best ones and create a mix for you all to enjoy soon.
Thanks in advance 'doctor'
I've just introduced this new topic about Greece. As you may know Greece doesn't mean just sun, fair weather and beaches. Furthermore, the very complicated orography can affect the weather from a place to another even if the distance is just a few Kilometers. So, I will use this topic to prove what I said . Of course, if anyone has any comments, queries or even matterial from Greece, he/she can upload.

Hi everyone, have decided to start up a separate topic to look more closely at expected rainfall accumulations in the days ahead. It's a concern that more new floods are possible if not likely through this weekend and into next week, this coming from several large scale weather systems and possible Atlantic storms hitting the UK and ROI over the next 7 days at least, it's likely that some breaks in the rain will occur at times though.
I'm not going to hide the fact that severe floods in new areas are possibly on the way I say possibly even if I think likely, which I do.
Below I've put on a rain alert map created from precipitation data models of which the one's I have access, please use my map as a general guide of where the heaviest rain could be accumulated over the next 48hrs or so, please do allow for some small adjustments do not take the map as 100 percent set in stone, usually the expected accumulations of rainfall may be more or less in any one area and exact locations can change, I might not be able to update map.
(Map can be shared where you like)
Map expires MON 0300hrs - January 4
W = on the map this means that I am watching for upgrades of 30mm or more.
Light yellow + W =30mm - rainfall may get accumulated up to 30mm but may upgrade to 40mm for a level 1 so is under a watch zone.
Yellow = 40mm - 50mm accm rain
Orange = 50mm - 80mm accm rain
Red = 80mm - 100mm accm rain
Dark red = 100+ accm rain.
Many areas seeing rain this heavy at times some very heavy and prolonged, expect 10mm-25mm generally.
Some of the largest rainfalls likely to occur over higher ground.
For the winds associated with these weather systems/storms likely gale or severe gale at times please see other threads and warnings.
Please post anything related to rainfall forecasting, model ppn data, alerts and warnings, your own rain maps and forecasts.
