I know nothing but have just watched the 6 o'clock BBC1 national forecast.
They showed a strong convergence line, and highlighted it spanning a lot of England with potential heavy rain and thunder storms. They also mentioned that the odd funnel cloud might be seen.
Calling out to the boffins on here...
Any truth to this?
(The BBC website forecast as of now 18:50 is 2hrs old and doesn't mention this)
