Pockets of Heavy Rain Plaguing Central Europe

A storm delivering pockets of potentially flooding rain and unseasonably cool air will not be quick to leave central Europe.

Rain will continue to wrap around the storm from southern Poland to Germany to France through Thursday as showers and thunderstorms rumble across northern Italy and the northern Balkans.

The majority of the rain and thunderstorms will create disruptions to those with outdoor activities, such as the Tour de France.

However, there will be pockets of heavier rain that threaten to worsen the situation for residents and motorists by potentially triggering flash flooding. Even where flooding does not occur, the downpours threaten to reduce visibility for motorists and heighten the risk of vehicles hydroplaning at highway speeds. Flight delays are also possible.

Such downpours are especially a concern across southern Poland and into central Germany through Thursday. Berlin will face another soaking on Thursday after Wednesday's drenching thunderstorms.

The band of rain that presses through Berlin during the day should drop into southern Germany at night.

AccuWeather.com Meteorologist Tyler Roys is also concerned for another pocket of heavy rain and potential flooding issues in the northwestern Balkans, over northern Croatia and Slovenia.

The same storm delivering the downpours through Thursday created problems on Tuesday.

"There were multiple reports of flooding across eastern Germany from Berlin to Prague Tuesday, where between 19 and 25 mm (0.75 to an inch) of rain fell with locally higher amounts," Roys continued.

"Thunderstorms fired up in the afternoon across Czech Republic and quickly became strong to severe with wind damage just south of Dresden, Germany. These storms became a cluster as they headed towards Berlin, where the storms pushed through during the evening commute."

Roys added that the recent rain is the most significant for the area so far this month.

Berlin received 31 mm (1.22 inches) of rain Monday and Tuesday before Wednesday's rain and thunderstorms streamed in. Prior to Monday, only 3 mm (0.12 of an inch) was recorded during the first week of July.

The storm is noteworthy not only due to the locally heavy rain and thunderstorms, but also the unseasonably cool air in place across central Europe.

High temperatures on Thursday will be held 4 to 8 degrees C (8 to 16 degrees F) below normal from eastern France to western Czech Republic and the northern Balkans.

Warm air is in place across eastern Europe, which may set the stage for locally severe thunderstorms to erupt from eastern Romania to western Ukraine as the slow-moving storm crawls eastward on Friday.

The storm's departure does not mean an end to the unsettled weather across central Europe. Additional storm systems will instead track in and trigger daily showers and thunderstorms through the weekend.
