Convective/Storm Discussion Thread - 19th May 2018 onwards

Recommended Posts

I am up a well known pointy tower in London until about 3pm today - then I have my van parked at Woking from where I can chase for a couple of hours.

Then it’s all eyes to the south east overnight for some patchy chances of electrical showers from the continent.

Not bad chances for the first day of a potentially exciting week of weather!

was that the one a month ago sat night 21st april? that one started at 7pm here (south coast near iow) and went on til nearly 2am came from france (we had some short spells without storms but most of that time there was at least distant lightning)

Thats the one friend. It literally got inside the M25, just outside audible/visual range then all activity just stopped dead.

Yep didn't do anything east of East Sussex either, only rain for us.

Have to say the radar doesn't look promising, a lot of messy, undefined returns piling into the south east, cloud cover could easily ruin the day genuinely as well as convectively speaking.

The SR model shows this (not perfectly) but there or thereabouts. Showers start to crop up ahead of that, and turn very heavy across Hampshire and Dorset around 4/5pm.

I know this is for UK based convection but looking at the charts and some serious eye-candy charts over the continent pretty much every day. IF some of that energy particulairy later on could make it over here to the UK.....................

Agreed, not often we need to look to the east, north east! I don't think I have a suitable storm watching spot on that side of the house!!

I'm busy in the garden today - needing to do some fibreglassing. It's a 'do I' or 'don't I' situation though, as it needs to be done quickly, but I don't want any rain to effect it. My cam is pointing to the East, so I can quickly check on it from time to time. :D

 

A few small Cumulus clouds popping up.

My office at JPM faces NE, I can see some Cu starting to pop up.

Got 360° view atm but the glass on these windows is quite dirty (London air) so visibility isn’t great.

what I can see is high level murky cloud so from a convective viewpoint I don’t think London will do perticularly well out of this today

Clouds bubbling up here readily at the moment and shown well by sat24 which indicates rapid development from the Southern Pennines down to the Midlands, presumably along a convergence zone?

Much sharper, crisper convection now occurring over the East Dorset / West Hants border, wouldn't bet against some radar echoes becoming evident in the next 30minutes.

Has been cloudy and not massively warm all day. Can't see us getting much out of this.

Could be that high level stuff that evaporates on the way down?

Virga I think.

(dunno if that shows up on radar, and not sure the conditions are right to support it)

      A shiny new thread as we head into the second half of July and the mid point of the summer.

      What a summer it has been. We started the summer with a lot of thunderstorms as June came in with a bang. Unfortunately as June came to a close and we moved into July the temperatures dropped and so did the storm risk. The most thundery early June I can remember has been balanced by the poorest early July I can remember. This looks like it is all set to change though as temperatures rise and summer returns. 
      Temperatures are already rising across the south and this building warmth and humidity will spread northwards through the early part of the coming week, with the heat likely peaking on Tuesday. The first 30c is very likely this week. The increasing heat and humidity also looks likely, on current modelling, to culminate in the possibility of some dramatic thunderstorms.
      The thoughts of Weather09 in the previous thread provide a good view of what we could expect from current modelling, seen on page 140 of the thread. The very high CAPE values being modeled for Tuesday are unlikely to be realised with strong ridging. It is currently late Tuesday night into Wednesday the period of interest (subject to change of course). Pin pointing an area to be at risk at this range is pointless.

      I am thinking this thread is going to get busy with lots of excitement, forecasts and thoughts regarding what is likely to happen, even what you are hoping will happen. I am hoping it will be busy with lots of reports of thunderstorms and convective activity by the middle of this week and beyond. I think most of us would not want to see it fill up with "why do I always miss out", "nothing here", "wishing for no storms" or other moaning posts that should be in the correct moaning thread like the one below.

      Good luck to all those that want a storm. 
      A chart showing MLCAPE for early Wednesday, just to get the excitement flowing
