A cold air mass currently affecting the Czech Republic will be replaced by a heatwave later this week. Temperatures are currently ranging from 7 to 11°C in the mornings. Tuesday morning is expected to be even colder. However, a warm air mass will begin flowing in from the southwest starting Wednesday. Meteorologists predict temperatures will climb above 30°C by the end of the week, marking a significant shift from the recent cool weather. This rapid temperature change follows a period of unusually chilly conditions for this time of year. The forecast indicates a return to summer-like temperatures across the country.
