According to the AccuWeather Global Weather Center, bouts of rain will suppress heat in the United Kingdom and Ireland.
High pressure sitting to the west of Ireland and the UK is forecast to keep extreme heat at bay, and to direct Atlantic depressions between Iceland and the British Isles.
While the center of the depressions will often pass near or north of Scotland, rain will frequent much of the UK.
“After a wet start to 2016, the unsettled weather will continue into the summer months, which means there could be enhanced localised flooding, especially in areas that are trying to still clean up from the floods in early winter,” said AccuWeather meteorologist Tyler Roys.
Frontal boundaries accompanying the depressions will sweep through the UK and Ireland, ending any warmth and resulting in seasonable temperatures for much of the summer months.
The frequency of these fronts and a flow off the Atlantic Ocean for much of the summer would rule out the chance of extended heat waves.
These fronts will also bring occasional thunderstorms with downpours, lightning and hail.
The predominant storm track for the summer months will send storms from the north Atlantic Ocean eastward into Scandinavia and the Baltic states.
The result of this pattern would be occasional heat building northward, and interacting with cold fronts racing eastward across western and northern Europe.
This interaction could bring numerous episodes of rain and thunderstorms — even tornadoes — from France into Germany, Poland and the Baltic states.
Further south, severe weather is predicted also for Italy and the southern Balkans — in the form of the warmest summer in recent years bringing drought concerns.
According to the AccuWeather Global Weather Center, the greatest drought risk in these areas will be from July into August, when the danger of water shortages, poor crop yields, and wildfires.
