Poland’s Institute of Meteorology and Water Management (IMGW) predicts a warm but potentially rainy Easter weekend, with localized frosts possible on Good Friday and Holy Saturday.
Climate Trends and Warming Temperatures
A climatologist from the University of Łódź stated that Poland remained under the influence of cold air masses from the North Atlantic until Thursday. From Thursday onwards, a high-pressure system is expected, leading to rising temperatures.
Temperatures are forecast to rise above 17°C, and in some regions even exceed 20°C, by Sunday and Monday, promising sunny weather, according to Dr. Mariusz Siedlecki of PAP.
Easter Weekend Weather Outlook
The IMGW forecasts a warm but rainy Easter. Przymrozki (frosts) are possible in some areas on Good Friday (April 3rd) and Holy Saturday (April 4th).
Hydrological Situation: Moderate with Rapid Thaw
The current hydrological situation is assessed as “average.” Despite a cold and snowy winter compared to the last two decades, the early spring thaw was relatively quick.
The expert noted that the winter created good hydrological conditions, but March was dominated by high-pressure weather, leading to a rapid thaw and a lack of significant rainfall in many areas.
Impact of Snow Cover and Evapotranspiration
The expert explained that snow cover plays a crucial role in Poland’s climate, acting as a water reserve released in early spring for vegetation. However, snowfall in Poland has been scarce or infrequent over the past two decades.
Last winter’s precipitation levels were comparable to those of the 1940s and 1950s. However, the subsequent high-pressure weather in March, combined with evapotranspiration, reduced water resources in the environment and soil.
Early Spring Arrival and its Consequences
Climatologists have observed that spring is arriving earlier in Poland in recent decades, with a shortening of the pre-winter and pre-spring periods. This results in a more significant transition between seasons, with both positive and negative consequences for various sectors.
The early arrival of spring can benefit certain crops like corn and grapes, but it also increases the risk of frost damage, particularly to orchards and gardens.
Agricultural Impacts of Early Spring and Frosts
While grain farmers can manage the process to some extent, fruit trees and other plantations are more vulnerable. The combination of early spring and frost can have negative consequences for these crops.
Persistent Drought Trends
The climatologist from the University of Łódź believes that the drought observed in central Poland is a persistent trend that will not be quickly reversed. Even with seasonal or annual precipitation within normal ranges, the water resources in the environment are diminishing.
This is due to increased evapotranspiration in warmer conditions and a shift in precipitation patterns from gentle, prolonged rainfall to heavy downpours, which quickly run off without adequately replenishing soil moisture.
