It was to my west, possibly over the laindon area. It's since dissipated but signs of Undulatus appearing now, if it develops further I'll get a pic but it's very sporadic and short lived!
In the interest of not blowing too much money on fuel I would be heading towards Kings Lynn. Going due South might not produce anything.
Basically we're currently looking at a slice drawn between the IOW to the NE and eastwards anywhere along that line.
The storm over Basildon is moving very slowly. It was raining across the street and took several minutes before it reached my side to the South. Another IC flash and several rumbles while typing this reply!
That new cell south of Harlow has my name on it. Winds locally moving S/E, very moody and impressive looking skies
Edit to add: Now the sky has turned pink!!!!!
It's dragging its heels for sure. Not so quick and could dump a lot a water in a short time. I'm expecting it to arrive in the next hour, hopefully it will still be electrified!
