After a prolonged "gentle September summer," Ukraine is set to experience a significant cooling, according to forecasters. Rain will become noticeably more frequent, and the sun will more often hide behind the clouds. This is reported by RBC-Ukraine, citing a Facebook post by Vitaliy Postrihan, head of the Cherkasy Regional Hydrometeorological Center. The expert emphasized that the calendar already shows the second half of September, yet it is hard to call the current weather truly autumnal: "the atmosphere is prolonging summer," and the average daily temperature remains above normal, more in line with the climate of the early part of the month.
What is happening now and until Sunday, September 20
According to Postrihan, until Sunday, September 20, the country will continue to enjoy a "gentle September summer" — warm, relatively dry, and sunny weather, atypical for late September. The forecaster noted, however, that changes in the weather situation have already begun: atmospheric processes are being restructured, and the stable warm background is gradually giving way to a colder, wetter air mass.
The change on September 21: a cold front and Scandinavian air
A noticeable change in the weather is expected on Monday, September 21, when conditions will shift to a more typical autumnal mode. As Postrihan explained, a cold atmospheric front of a deep Atlantic cyclone will cross Ukraine, which, in his words, "will finally bring the long-awaited rains so needed by farmers for the sowing campaign." Along with the northern winds, cold, moist air from Scandinavia will enter the country, ensuring a marked drop in temperature.
Forecast for the work week of September 22–25
For the next working period — September 22–25 — the expert provided "preliminary model estimates": nighttime air temperatures will be +7…+12 °C, daytime — +12…+17 °C. Postrihan recommended preparing umbrellas and light jackets in advance. The cold wave is expected to be noticeable but, according to his data, so far without frosts, which removes the main threat to field work and unharvested crops.
Impact on agriculture and "pleasant pauses"
The absence of frosts, according to the forecaster's conclusion, means there is no threat to unharvested vegetable crops — the harvest can still be left in the fields. In closing, Postrihan noted that even under the "cyclonic pressure," nature will leave room for pleasant pauses, i.e., periods with clearings and more comfortable conditions. It is important to emphasize that the figures for September 22–25 are preliminary, model-based estimates and may be refined as the observation date approaches.
