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.

Can't say I've ad any of that rain and I'm directly below where it's meant to be.

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)

      Storm & Convective Forecast

      Issued 2018-08-06 21:33:50
      Valid: 07/08/2018 00z to 08/08/2018 00z
      THUNDERSTORM OUTLOOK - TUESDAY 7TH AUGUST 2018
      Synopsis
      North Atlantic upper trough will begin to amplify S and SE across the far west of Britain during Tuesday, with a strengthening upper flow across the UK – as SWly jet stream shifts S and E across the UK. Ahead of the jet streak, a weak surface cold front will progress slowly east, to lie North York Moors - West Sussex by 00z Weds. A very hot, humid and increasingly unstable airmass ahead of the cold front across SE England and East Anglia is forecast to destabilise and produce thunderstorms in the evening here before the front clears through and introduces cooler and more stable air.
      … SE ENGLAND and E ANGLIA …
      Surface-based CAPE will build up through the day due to surface heating of humid plume in conjunction with lapse rates steepening in association with advection north of EML (elevated mixed layer) aloft. However, this surface instability is likely to remain capped. However, a shortwave in the strengthening flow aloft will move NE from Bay of Biscay area in the morning crossing NW France in the afternoon. The increased lift by the shortwave along NW edge of hot and humid plume over France and SE UK combined with increasing mid-level instability as dry air intrusion punches NE overlapping plume, is forecast by many models to break out thunderstorms across Brittany and Normandy by early evening, before spreading / expanding NE across SE England then East Anglia through the evening.
      Thunderstorms are likely to be elevated, though 40-50 knots of 0-6km shear forecast will allow storm organisation into clusters, perhaps even an MCS passing over parts of Kent and eastern E Anglia, so there is potential for strong storms that may bring locally intense downpours leading to flash-flooding, isolated hail, strong wind gusts and frequent cloud-to-ground lightning. These storms should clear away NE into the North Sea after midnight.

      Just found one I snapped in Canada a few years ago that was building into a nice thunderstorm

      As requested by @Dami, a new thread for the new convective season.
      Reckon I'll be spending a bit of time in here
