TORRO CONVECTIVE OUTLOOK
Over the next few days, the British Isles are at risk from severe weather, mainly in the form of high winds and heavy rain. Some of the strong winds are likely to be associated with severe convection, and there is a slight risk of tornadoes in a few places.
The first risk, albeit fairly small, will be on Thursday afternoon and evening, as a cold front moves eastwards. There are some indications that across southern and central parts of England and Wales, line convection may develop in a region of reasoble low-level shear...thus, misocyclones may develop, enhancing the chance of strong winds and isolated tornadoes.
A more vigorous set of fronts will cross the British Isles through Friday and Friday night. The cold front and triple point of this system may be areas where convection is possible. With strong winds throughout the atmosphere, changing in direction with height, a few tornadoes may be possible, along with some strong wind gusts. The system will also produce strong winds away from convection too.
