Weather forecast

I was refusing to do it but I’ve started to use personalized google start page. I’ve added a weather forecast plugging and I’ve choose three differents cities: London (’cause we we’re last summer and I like it), my hometown, and finally Rome (’cause we want to go this winter, specially to visit vatican museum and sixtin chapel).

What I’ve found interesting is how forecast are changing during from one the to other and even during the current day. So that makes me remember that a forecast twenty-four hours in advanced is guesswork
