A linear segment has formed over N Alps and is progressing towards the lowlands, where surface station readings show temperatures of 32 - 33 deg C and dewpoints of 16 - 17 deg C. Large temperature and dewpoint spreads suggest potential for abundant evaporational cooling in downdrafts. Thus, severe wind gust threat is expected to increase in the next two hours. Given the 18 m/s of 0-6 km bulk shear in the 12 UTC Vienna sounding, linear segment will stay well-organised and can persist for a long time.
