Small snow cover was observed locally in northern part of the left bank of Dnipro river and somewhere in central oblasts. In the last day of the reporting period, rain and wet snow resulted in formation and extension of ice slick to the first level of danger in western, central, northern and southern oblasts.

The average air temperature was lower than the norm by 1.2-3°С across most of the country. The maximal temperature reached +1-6°С in the warmest days. It reached +7-11°С in most of western, Vinnytsia and Kherson oblasts, and +12-16°С in Ivano-Frankivsk, Zakarpatska and Odessa oblasts.

The minimal air temperature declined mainly to -9-13°С. It decreased to -6-8°С in Ternopil, Chernivtsi, Kherson and Volyn oblasts.

The temperature of soil surface or snow declined to 10-16°С at night. It reached +1-17°С in the warmest days.

Slight precipitations  in form of drizzling rain, rain, wet snow and snow were observed during 1-3 days across almost the entire territory of the country. The average amount of precipitation totaled 5-25% of the norm (1-5 mm).

At the beginning of the reporting period, vegetation of winter crops in tillering phase stopped in Poltava and Dnipropetrovsk oblasts due to decline of the average daily temperature.

Weather conditions were not dangerous for wintering of crops in Ukraine. However, short-lasting decline of minimal temperature at the tillering zone depth to -9-10°С could negatively affect the wintering of underdeveloped barley and rapeseed in Sumy, Kharkov and Luhansk oblasts.

The minimal soil temperature at the tillering zone depth varied from +1°С to -5°С across the rest of the territory. It declined to -6-8°С in eastern, northeastern regions as well as in Poltava, Dnipropetrovsk, Kirovohrad and Zaporizhia oblasts.
