Ukrainians are expected to have mostly dry and sunny weather during the upcoming weekend, July 18 and 19. However, meteorologists warn that atmospheric processes in the western regions of the country will create conditions for downpours and thunderstorms.

According to the forecast by synoptic Natalka Didenko, as reported by RBC-Ukraine, an anticyclone will play the main role in shaping the weather over the weekend. This atmospheric system will block precipitation from reaching most regions, ensuring clear skies and comfortable conditions for leisure.

Convergence line: where to expect bad weather

The western regions are the exception. A "convergence line" (or instability line) is expected to pass through here. On meteorological maps, this zone is marked by a yellow line with spikes.

The expert explained the mechanism of precipitation formation in this zone:

  • Convergence: the process where several air streams converge into one channel.
  • Convection: the activation of vertical air movement. "This is the main engine of downpours, thunderstorms, gusts, and hail," Didenko clarified.

The meeting of warm, light air rising upwards and heavy, cold air sinking downwards triggers heavy rains. The synoptic advised residents of western regions to return home a bit earlier than usual, as thunderstorm fronts may advance further by Sunday evening, July 19.

Temperature regime and forecast for Kyiv

Across the rest of Ukraine, daytime air temperatures will range from +24°C to +29°C. In some areas, thermometer readings may rise to +29...+31°C.

Natalka Didenko noted that summer weekends are becoming fewer and urged people not to stay at home but to enjoy the moderate continental climate, which does not yet show such extreme figures as +40°C in France.

Kyiv is also expected to have predominantly dry and sunny weather. Nighttime temperatures in the capital will correspond to the seasonal norm, according to data from the Ukrainian Hydrometeorological Center. Meteorologists continue to monitor the situation to provide residents with accurate data on atmospheric conditions.
