Thunderstorms are expected to form over large parts of the Iberian peninsula later in the afternoon. Moderate instability is present, with virtually no shear and only weak capping inversion – expect widespread thunderstorm initiation. Thunderstorms will be high-based, with danger of dry lightning which will enhance the already high danger of wildfires. Additionally, there will be a significantly enhanced threat of severe winds from (dry) downbursts with these thunderstorms.
