The air masses are very warm, and the atmosphere remains unstable. The morning will be generally fine, although residual clouds from overnight showers may lead to variable cloud cover in some areas; furthermore, isolated thunderstorms cannot be entirely ruled out. With cumulus clouds building up in the afternoon, heat-induced thunderstorms are likely. A northerly foehn wind will pick up in some valleys. The maximum temperatures are well above average, reaching 27° in Sterzing, where the Föhn is blowing, and 36° in Bolzano.
