Constant rumbling here - how quickly this cell popped up is quite something.

Forecast soundings suggest the potential for MLCAPE on the order of 1,000-1,500 J/kg generally, but perhaps locally 2,000 J/kg where higher dewpoints exist, with cloud tops potentially to 40,000ft (-60C or colder). While flow aloft will be fairly weak (~15kts at 500hPa, for example) a reasonable degree of low-level wind shear is evident with slightly backed near-surface winds. Despite limited shear, the magnitude of instability may be sufficient for the strongest cells to become better organised with potential for some transient supercell characteristics. This is a ramposauras-rex. I'm actually flying out of Heathrow at 4pm today, heading SE - could be a little interesting!

Did anyone catch the BBC Look East and national weather forecasts about an hour ago - it could not have been more different two forecasts just 2 minutes apart! How are the prospects looking for Bedfordshire?

No lightning that I've seen though - pretty intense rain which I was caught in. A nice drink for the plants.

Brief power loss here in central Bedfordshire.
