During the work week, afternoon temperatures tempted people to the water, but mornings were cool and frosty in mountainous areas. But that will change over the weekend when overnight temperatures also go up, and the thermometer’s mercury will stall at tropical levels in the afternoon.

The subsequent rise in temperatures will come at the beginning of the new working week, meteorologist Dagmar Honsová said. Afternoon temperatures will peak at 34 degrees Celsius.

Thursday will be partly cloudy, with clouds in the northeast during the day and showers or thunderstorms in places. Morning temperatures ranged between 13 and 9 degrees Celsius. Temperatures will range between 24 and 28 °C during the day.

Friday will be partly cloudy with some clouds and isolated showers or thunderstorms during the day. Morning temperatures ranged between 13 and 9 degrees Celsius. Temperatures will range between 24 and 28 °C during the day.

The weekend will be full of sunshine and high temperatures. Saturday will be partly cloudy, with intermediate to cloudy skies in the afternoon and occasional showers or thunderstorms in the north and northeast. Morning temperatures range from 15 to 11 degrees Celsius—temperatures during the day range from 26 to 30 °C.

Sunday will be partly cloudy, with showers or thunderstorms during the day. Morning temperatures range from 15 to 11 degrees Celsius. Temperatures during the day range from 27 to 31 degrees Celsius.
