According to the Sinoptik.ua service, on June 13 and 14 a cold atmospheric front will briefly enter Ukraine, causing thermometers in different regions to drop by 3–7 degrees.

In the west of the country on June 11–12, thunderstorm rains are expected, with daytime air warming up to 21…23°C. The exception will be Zakarpattia, where no precipitation is forecast. On June 13–14, it will become noticeably cooler in this region — down to 17°C during daylight hours. Thunderstorms will cease, but light rains are still possible. This temperature drop will not last long.

In the southern regions, from June 11 to 13, warm and humid weather will persist, with thunderstorms gradually weakening. In Odesa, the chance of precipitation on Saturday is minimal. On Monday, June 14, the temperature will drop slightly, and rains will return. The hottest period from June 11 to 13 is expected in the Kherson region — up to 27°C. In Mykolaiv, Saturday promises to be the clearest. Sea water off the Odesa coast has warmed to 16.2°C, and in Berdiansk in the Sea of Azov — to 20.8°C.

In the eastern regions, from June 11 to 13, daytime temperatures are expected up to 24°C. On Monday, a slight cooling is possible. Throughout the period from Friday to Monday, rains of varying intensity and frequency will occur in the region. The wind will blow from the south, from light to moderate. The weather these days will be unstable, so it is better to always carry an umbrella.

In central Ukraine on June 11–12, temperatures will reach 24°C, and in the Poltava region — only 21°C. On June 13–14, it will become cooler, with a particularly noticeable temperature drop in the Vinnytsia region. Rains, as across the country, will not bypass this region either. A likely scenario: in the morning — sun and light cloudiness, warm, possible brief rain; in the afternoon — clear again, but suddenly clouds will gather and a thunderstorm will break out; in the evening — no precipitation, temperature the same as in the morning, air slightly humid and stuffy.

In the north of the country on Friday, daytime temperatures are expected at 21…23°C, on Saturday — up to 25°C. On Sunday and at the beginning of next week, temperatures will drop by a few degrees. From June 11 to 14, rains will occur in these regions, with the heaviest forecast for Sunday.

In Kyiv, at the end of the work week, the weather will be very changeable: sun will alternate with rain, thunderstorms, cloudiness, and clearings. Daytime temperatures will be 22…23°C. On Saturday, precipitation is unlikely, and the air will warm up to 24°C. On Sunday, it will become cooler by 3–5 degrees, with more rain, but sunny periods are also possible. Monday will be almost indistinguishable from Sunday in terms of weather conditions.
