The weather forecast

In other words, the weather will be the sort of weather one would normally expect in Britain at this time of year

A visitor to my house described what we have hanging on the walls as 'eclectic'. It's true that our pictures are from various different sources and different parts of the world.

A secondary meaning of eclectic is 'made up of a variety of elements from different sources' so I suppose it could describe mixed and chaotic weather, although I think it more usually describes a mixed crowd of people.
