For the third time this summer, parts of Europe will soon be dealing with another heat wave. Temperatures will climb some 20 degrees above average in spots beginning this weekend, baking much of Eastern Europe and Scandinavia in unseasonable warmth.
The culprit for the hot weather will again be a strong area of high pressure aloft, or heat dome, that will set up an atmospheric squeeze-play of sorts between low pressure on either side. This will draw a flow of unusually warm air northward.
On Saturday, the heat will begin to crank up across most of Europe before consolidating over central Europe on Sunday. By Tuesday, a bubble of significant heat will pinch off and settle over Scandinavia, while the rest of the dome will settle south and reorganize over the Balkans.
The sweltering conditions are set to arrive in Germany on Sunday, when Frankfurt could hit the upper 80s. Then they will be within a degree or two of 90 on Monday, Tuesday and Wednesday — pretty impressive considering the average high there this time of year is just 71 degrees.
