The historic first part of April for Europe ends with two intense heatwaves Off-season, which broke hundreds of temperature records in the plains and mountains. France, Spain, Austria, Switzerland, Slovenia, Croatia, Slovakia and Bosnia are among the countries most affected by the effects of the powerful hurricane. For many states, it had never been as hot as it is now before April 15.

April 15-22. It is expected that the severity of the thermal anomalies will decrease throughout the week due to the cooling of the air, which will lead to a drop in temperatures by more than 15 degrees Celsius. Cold air, which will not be as exceptional as hot air, will partially reach the peninsula, which will also lead to increased instability. The precipitation will mainly affect the center and south, especially the eastern slopes

If it were not for the hundreds of temperature records, a recurring number of unseasonal heat waves, a number of records that have been broken by a large margin, and positive anomalies spanning large areas of Europe, there would be nothing strange about seeing ups and downs in spring. The record heat also accelerated the growth of plants that are very sensitive to the coming cold. Early flowering of fruit trees is a frequent occurrence in recent years.

April 22-29. Relatively cool air continues to flow into Europe, with below-average temperatures in the central northern states and the Mediterranean region. The anticyclone will remain unbalanced in the Atlantic Ocean and allow unstable currents to enter from northern Europe towards the Mediterranean basin.

May 6-29. The model shows little change from the previous week. Even with a weak signal, there is a possibility that the below-average temperature scenario in Europe will continue.

This scenario also confirms the AIFS beta which remains in place from multiple exits.

This change in circulation derives from a new baric rearrangement due to the development of Rossby waves. The new pattern is supported by the dampening effects of the stratiform explosion that occurred on March 4th.
