A slow-moving, waving cold front will push eastwards during Wednesday bringing some much needed rain across parts of central, southern and eastern England. Riding along the eastern edge of this area of rain will be a marginally unstable airmass. There are two options for convective showers/lightning. One being from storms that generate across northern France and become elevated as they move across the Channel and become embedded with a more complex area of rain as the front approaches. The other being if there is any bright/sunny spells ahead of the front during the day on Wednesday and this could spark surface based thunderstorms in the southeastern corner of England. The highest risk in the brown sausage will be across eastern parts of Kent, Essex and Suffolk. If lightning does develop in this scenario, it could become frequent enough to warrant a slight risk.
