After a mostly dry weekend, the weather in Ukraine is changing sharply: according to the Ukrainian Hydrometeorological Center, as reported by RBC-Ukraine, the country will be covered by rain on Monday, September 21, bringing with it a noticeable drop in temperature. Meteorologists are noting a shift in the atmospheric conditions, which, after a period of calm, restores the typical late-September coolness and precipitation across most regions.
Precipitation: moderate rain almost everywhere
According to the Ukrainian Hydrometeorological Center's forecast, moderate rain is expected in most oblasts of Ukraine on September 21. The precipitation will be most intense in the northern and central regions, where heavy rain is forecast in places. These zones will become the "epicenter" of today's atmospheric processes, while the rest of the territory will receive moderate but steady precipitation.
Temperature drop of 4–6 degrees
Along with the rain, a cooling spell is arriving in the country: air temperatures will fall by 4–6 degrees, with the exception of the southern and eastern oblasts, where the drop will be less pronounced. During the day, temperatures across the country are expected to range from 18 to 25 degrees Celsius. Thus, after a relatively warm, dry weekend, the weather is returning to cooler, "autumnal" values.
Wind and atmospheric fronts
In addition to precipitation and falling temperatures, according to reports from specialized outlets, atmospheric fronts are moving across the country, accompanied by strengthening winds. In several regions, including in the east, meteorologists specifically note the influence of these fronts, which are responsible for both the rainy and windy weather in the coming days. This is a typical picture for the period when a warm air mass gives way to a cooler one.
Context: Indian summer and how temperature is measured
The weather shift is happening against the backdrop of recent discussions about a "young Indian summer" — how and when autumn actually arrives in Ukraine. In parallel, the Ukrainian Hydrometeorological Center reminded the public how exactly specialists measure air temperature and why home thermometer readings can "lie," failing to match official data. This is important to keep in mind when comparing personal experience with the forecast. In any case, September 21 is a day when an umbrella and a warm jacket once again become essential items of the day.
