A total solar eclipse is expected to occur on Wednesday, altering weather conditions along its path from the Arctic to Western Europe. The eclipse will cause changes in temperature, wind speed, and humidity as the Moon blocks sunlight from reaching the Earth's surface. The amount of blocked radiation will determine the extent of the changes.

This effect is similar to the difference in temperature between shaded and sunny areas on a hot day. Further details about the eclipse and its effects on weather conditions are available from meteorologists Mary Gilbert and Chris Dolce at CNN.
