Greece, the Balkans, Poland: Drought Concerns
Throughout the winter and through the beginning of the spring, southeastern Europe experienced very wet conditions, keeping temperatures within the normal range for most cities.
This summer, the core of the heat will be over western Russia and east of Ukraine. This heat will spill into eastern Europe as the summer kicks off, however, and will begin to dominate.
"This strong ridge over southeastern Europe will make for a very concerning pattern," AccuWeather.com Meteorologist Alan Reppert said. "Especially late in the summer, as we get into some of the long and hot days in August."
Temperatures could push as high as 2 to 4 degrees C above normal at times in some areas. In Athens, in particular, heat will be locked in midway through June, and that warmth will likely push into Rome and other major cities in the south.
This heat will increase the threat of fires from the dry vegetation that grew over the winter and spring.
"If it does get hot and dry, that vegetation will dry out and die, and all you will need is something to set it off," AccuWeather.com Expert Meteorologist Jason Nicholls said.
Abnormally dry conditions could evolve into significant drought in late June or July.

"There will be shots of cooler air at times into July," Nicholls said.
