A tropical heatwave is set to return to the Czech Republic this week, following a brief period of showers and thunderstorms early in the week. The beginning of the week will see high temperatures, but scattered rainfall is expected in the evenings. Following this, the rest of the week promises sunny skies and pleasant summer temperatures. However, temperatures will rise again as the weekend approaches, bringing another wave of intense heat. Authorities have not issued any heat warnings at this time, but residents are advised to stay hydrated. The shift indicates a continuation of volatile weather patterns experienced across the region. Overall, the forecast suggests a largely pleasant week, punctuated by a return to potentially scorching conditions.
