No. If you watch an elevated storm reach the Home Counties it remains very pixelated. For the duration of the storm. Watch next time there’s an elevated storm.

Have to be honest with you that is not the case, it's just coincidence that we see a lot more elevated storms drift up from France. We do occasionally see home-grown elevated storms and they do not exhibit the characteristics you have outlined on the radar. @staplehurst has the best explanation

A storm  not far away from me. Still don’t think it will reach here because  of the sea-breeze although it doesn’t seem to be having much affect on the temps 21.0°C.

That would also explain why that little corner of East Anglia always looks lower resolution on the radar! I've always wondered why!

I suspect that is heavily reliant on how close the storms are to each radar site (both horizontally and vertically) - if it's right near a radar site, the resolution is around 500m, but it gets progressively worse the further away from a radar site you are (such as over France, which is on the edge of the UK/Ireland radar network, or very high up vertically). Also, the further away from the radar site, the higher the beam is due to the curvature of the earth, and so it will be picking up precipitation more from the mid-levels rather than from the cloud base (depending on where the cloud base is, how tall the cloud is etc)

Do you have access to the doppler radars? Or are you stuck with the same non-doppler radar we all use too?

Despite requests, sadly not available commercially - yet!

Indeed, it's pretty poor coverage in East Anglia (even worse for Shetland!). There are hopes a radar site may be installed at Old Buckenham in the next few years, which would vastly improve the coverage over East Anglia and pick up a lot more of the shallow North Sea showers that often go undetected below the lowest radar beam

may be some interest soon.

Thanks mate. Learn something new everyday. Thanks for not being sarcastic and rude, and actually showing me the true reasoning behind it imagine being passive aggressive when someone’s wrong? It’s a bloody cloud mate chill out Paul 

And it's not sensible to hit back at someone by also being rude. Paul's sense of humour & sarcasm is quite unique and is a top bloke, just takes some getting to know him! Let's not to worry just a mis-understanding!

[Polar Maritime]

Let's move on please..

[OddSpot]

There is a storm brewing on this forum at least 

 

Hope this comes off

Euro4 shows an area of intense precipitation sitting just to my north (Matlock/Chesterfield) from this evening into the first part of the night. Check out the 6 hour accumulation chart from 6pm to midnight courtesy of weatheronline.co.uk

Moving on...here's a quick snap of the developing cell that was over Stockport at around 1pm. Woke up to see the clouds bubbling up and suddenly remembering today is storm-potential day again 

 

[Calayte]

Looks like some more showers starting to pep up over the West Mids, doubt anything will come of it here, will more than likely feed up to the NW

Yeah bro. Because when the storms are elevated it’s harder to get a high res image as radar returns aren’t very good. But when surface based it’s high res and can be seen much easier. 
 

I only learnt it recently ! 

Just to let you know that is not correct, the pixelated nature if the RADAR returns is due to range of the object from the RADAR head. It appears that the netweather RADAR only utilises the UK / Ireland Weather RADAR network including Jersey in the Channel Islands. So RADAR returns in NE France are being scanned at range from the RADAR at Thurnham in SE England and hence look more pixelated in output. In addition at this range even the lowest radar beam (I believe it's 0.5 degrees for Thurnham) is scanning storms over France at fairly high elevations (see the graph for WSR-88D), so will not pick up on showers produced by shallow surface based convection across NE France (tops below 8,000-10,000 FT), but will pick up deeper convection from surface based cells across NE France.

The storms are definitely edging towards your area.

Very disappointing outlook for storms here from an imby view, low cloud here most of the day, looks like tomorrow could be our best chance if any.

[Nick L]

If we can all act like adults, that would be great. Cheers.

Thanks I appreciate it

Posts that are not relevant to this thread are being removed. I would really like to be using this time to be storm tracking and not sifting through insulting comments. Please can we keep it friendly.

[Nick L]

Seriously, any further rubbish and you can sit out for a day or two. Stop ruining the thread for others.

Convective around here again today although not as much as yesterday, still keeping an eye on things though. Cloud sometimes have that real plumey look to them today too.

Im down near Oldbury and 100% see what you mean, got some good time lapses that show that really well

still a good amount of time in the day though! I don't believe it was convective so early on yesterday as it was today

very dark around here now sparkiee    seems to have really developed

[carl1980]

We have a storm in Kirkby a also thunder in St helens

[Zak M]

Didn't look promising here earlier and still doesn't to be honest but the clouds look to have a vertical component to them now.
