Nice rumbles of thunder and some nice lightning here.

That Cambridge storm has only been around for less than 5 minutes and has a very frequent strike rate 😮

Got some dark clouds to my east from a heavy cell a few miles away but not expecting anything here. Though these storms look decent

Rain was crazy at times. No show for the thunder tho. Here’s hoping for something later 👍

Drove through that lot near Ely. Big hail and some decent well defined forks! 

Best homegrown storm I’ve seen in quite a while!

Missed some strikes around Epsom because of the slew of temporary traffic lights across London. They are literally everywhere at the moment. Didn’t realise how close I was to Epsom downs racecourse but by the time of arrival the storm was already past - very quick moving.

Also couldn’t remember where the north-facing vantage point was, so a 3/10 for that storm based on lack of preparedness 😄

Just saw that lot flash up on Blitz! Mind you the columbus clouds I can see here are massive, and high up - Impressive sights really.

They seem to be losing their dynamics quickly though. Got as far as Alfold and they look rather innocuous now.

Oh well - plume next week 🙂

Ooh, I'm nearly in the grey zone.

Day 1 Convective Outlook

VALID 06:00 UTC Tue 20 Aug 2019 - 05:59 UTC Wed 21 Aug 2019

ISSUED 06:04 UTC Tue 20 Aug 2019

ISSUED BY: Dan

A rather messy pattern on Tuesday, with an upper trough gradually departing eastern England while an upper ridge builds across Ireland - neither particularly pronounced. The surface pattern is rather slack with weak ridging. Frontal boundaries provide the focus for low-level moisture and convergence, with convective overturning through the day helping to aid the development of scattered showers. Other showers are expected to develop within the warm sector over Ireland too.

In most cases, weak shear, fairly saturated profiles and marginal instability suggest the risk of lightning from a given shower is rather low. However, isolated pockets of sporadic lightning may be possible.

I’m certainly not trying to be negative when I say this, but... isn’t it supposed to be HP dominated heat? As opposed to a heat pump/Cut off low scenario?

Yeah I think you’re right, but either way it’s better than cloudy 🙂

I think Lu prefers Italian storms going by her post refering to Columbus clouds..!!

I managed to capture lightning from the last storms we had here just over a week ago.

Day 2 Convective Outlook

VALID 06:00 UTC Wed 21 Aug 2019 - 05:59 UTC Thu 22 Aug 2019

ISSUED 19:38 UTC Tue 20 Aug 2019

ISSUED BY: Dan

An upper ridge will slowly exit to the North Sea on Wednesday morning, as an upper low approaches the British Isles from the Atlantic. An active frontal zone will spread a band of cloud and heavy rain across Ireland and Scotland, reaching NW England later in the afternoon. 

Elevated showers are likely to be located over the Celtic Sea at the beginning of this forecast period, drifting northeastwards across Wales / Midlands / northern England through the morning and afternoon. Additional surface-based showers may develop in response to diurnal heating, but in either case weak instability, limited convective depth and fairly moist profiles suggests any lightning will be rather isolated.

Elsewhere, ahead of the front a tongue of relatively high Theta-W will be advected northwards. Shear will increase substantially along the front during the afternoon as a notable mid-level jet rounds the base of the upper low. Elements of line convection may develop on the rear-side of the main frontal rain, although depth of convection will generally be too shallow for much in the way of lightning - though this perhaps most likely across parts of Scotland late afternoon / evening hours.

Behind the front, upper cold pool will overspread NW Scotland through Wednesday night, steepening mid-level lapse rates and generating numerous showers - although any lightning activity will probably be quite isolated.

Similar to what's showing up for where I live but with possible lightning between 2pm and 7 pm 😄
