Saw this scary satellite map on Midlands Storms Chasers Facebook page, If you look closely, you see a skull which looks like it's blowing wind, and it's nose is placed directly on top of the Midlands. :closedeyes: Sorry it's a bit off topic.

So today there's been thundery activity in the west, east, south and north, and yet again the Midlands produces nothing other than heavy rain at best. I'm wondering if there is actually a scientific explanation for this because if you look at the map bellow of the four stormiest days combined, there is a big gap of virtually no activity surrounded by over 300,000 strikes in total. It's insane, and the outlook isn't even good for the next few weeks, just a bit of sun but nothing eventful for sure.

Yet another lightning strike map that draws the borders of Shropshire very accurately; have seen quite a few like it....

Storm & Convective Forecast

convmap_230717.thumb.png.667f3bfd75941606355651bfa6ea10f8.png

Issued 2017-07-23 05:59:56
Valid: 23/07/2017 06z to 24/07/2017 06z

CONVECTIVE / STORM FORECAST - SUNDAY 23RD JULY 2017

Synopsis

Upper and collocated surface lows across eastern England will slowly drift east across the N Sea during the evening. An unstable Wly veerying NWly to Nly flow will cover England and Wales.

… ENGLAND and WALES …

Cold mid-level temperatures of upper low atop moist diurnally heated surface airmass will create steep lapse rates which will support the re-development of scattered heavy showers and thunderstorms today. A zone of wind convergence shifting southeast across England and Wales during the day could be the focus for storms to organise and train along, bringing a threat of localised flooding where they do organise. Otherwise weak vertical shear will mean showers and storms that develop will be dis-organised and pulse-type and will limit the potential for severe weather. Any showers/storms may produce hail and, like yesterday, there could be a few funnels or even brief weak tornadoes / waterspouts – especially where surface convergence combines with buoyant and strong updrafts.

Amazing how sunny and calm it can be inside the low pressure! This is the view to my east, towards the pennines. The low cloud doesn't even move in any direction.

There should be some nice development over the pennines this afternoon.
