Ukraine expects unstable weather on Wednesday, July 15, featuring short-term thunderstorms and potential hail across the country [1].
These conditions signal a volatile transition into a period of intense heat, posing risks to infrastructure and public health as temperatures climb rapidly toward the weekend.
TSN meteorologists said daytime temperatures will generally reach 31°C [1]. In southern regions and Zakarpattia, the heat is expected to be more intense, peaking at 33°C [1]. The Kyiv region may see slightly lower peaks around 30°C [7].
Beyond the temperature, the atmosphere remains unstable. This instability is expected to trigger short-term rain and thunderstorms in most regions [5]. In the Kyiv region, these storms are expected to be localized [6]. The TSN team said these weather systems could bring squalls and hail [1].
This current instability is a precursor to a more severe heat event. Forecasters said a strong heatwave is expected to arrive between July 17 and July 20 [1]. During this window, temperatures are projected to rise as high as 36°C [3].
The combination of sudden storms and extreme heat is typical for summer seasonal atmospheric instability [1]. Residents in the south and Zakarpattia are currently experiencing the highest thermal loads as the country prepares for the upcoming temperature spike.
“Temperatures are projected to rise as high as 36°C.”
The shift from volatile thunderstorms to a sustained 36°C heatwave within a five-day window indicates a rapid change in atmospheric pressure. This pattern often increases the risk of flash flooding from sudden storms followed by heat-related stress on the power grid and agricultural sectors during the peak heat period.
