The chart i posted was an 18z ensemble member from last night, that chart has changed now since the 06z came out, but what it showed was -16 uppers in london from a stonking easterly and - 14 uppers in cornwall, this is not common for the UK on the 14th of march as that is the date it showed,
i know its FI and will not happen as it a freak event but it was the best chart i have seen for march, but if it did happen it would go down as one of the best events in history for march that is
