Storms and Convective discussion - 10th April 2020 onwards

[Kirkcaldy Weather]

Interesting radar signature from the first band moving out into North Sea also done a sketch to show hook appearance

Some more convection happening to the south of me.

I'm pretty sure that hail is falling in the second picture on the left-hand side.

A couple more pictures, one from earlier this afternoon, the other just now after the latest shower passed over.

Got Some lovely looking sky and what looks like mammtus clouds on the pics

Not even a sniff of a rumble. Clouds were impressive tho.

Rainbow!

Here are some photos from my little storm chase today.

Storm passing over combined with the evening light giving a lovely double rainbow here - just in time for the NHS clap!

Look at the colours

I mean storm

A proper day of April Showers - just had a heavy shower pass over East London, our fourth downpour of the day.

What a difference a week makes - just 168 little hours - (as someone never said).

Some pretty convective clouds to complement the sunset this evening.

I just looked to the SW of me, and good god, it literally looks like the end of the world.

The picture doesn't do its justice, much darker in real life.

Some really nice convective skies today, nothing in the way of a storm though, we have had some much needed rain however 

[Weather-history]

Been a while since there has been some decent convection here

Day 2 Convective Outlook

VALID 06:00 UTC Fri 01 May 2020 - 05:59 UTC Sat 02 May 2020

ISSUED 20:24 UTC Thu 30 Apr 2020

ISSUED BY: Dan

A cold pool will reside over the British Isles on Friday, associated with a multi-centred upper low. In general, one low will be located over the North Sea, with another near Northern Ireland, and therefore slight ridging aloft over England between these two upper lows. Diurnal heating will gradually yield 200-500 J/kg CAPE, with numerous showers likely to develop - several will already exist first thing in the morning due to occlusion debris drifting southeast in the mean flow, but the coverage of showers is expected to increase by the afternoon. 

For the most part, shear is relatively weak and instability lower than Thursday, suggesting that lightning will be fairly isolated and hence the risk is considered just below SLGT threshold (20-25%). Convection may become particularly focussed during the afternoon and early evening along a pronounced low-level convergence zone stretching from SW Scotland across northern England towards Lincolnshire. 

 

Profiles from south Wales / south Midlands southwards into southern England will be drier and increasingly subsided, suggesting any showers here will be more isolated and generally not as deep. However, shear will increase here later in the afternoon and into the evening, and so any showers that do manage to develop could still produce a few isolated lightning strikes - particularly in SE England - but it will be somewhat of a fight between increasing shear and gradual reduction in convective cloud depth. Showers will weaken and reduce in number during Friday night, but are still likely to persist in places due to both proximity to the upper low and old occlusion debris.
