Meteorologists report that on Tuesday, 18 August an atmospheric front moving in from the west will produce cloudy, rainy conditions with thunderstorms across Kyiv Oblast. In some districts authorities expect hail and squalls reaching 15–20 m/s; the region has been placed under a yellow-level weather alert. Winds will be predominantly southerly at 7–12 m/s. Daytime temperatures across the oblast are forecast at 28–33°C, with Kyiv itself around 28–30°C.
Forecasters say unstable, summer-like weather will continue in the region through 22 August, with showers and thunderstorms possible by night as well as by day. After the front passes, 19 August may bring cooler nights and milder daytime temperatures due to a brisk westerly wind. Big Kyiv cites the Ukrhydrometcentr advisory; residents should check local updates, allow extra travel time during storms, and be prepared for temporary interruptions to energy, construction and municipal services.
