Enigma in linea «Rainy day»

In childhood, on the television broadcast the weather forecast. And often said "the Rain in some places". And I still could not understand how it is sometimes when it rains everywhere he goes. And once I went once by car and it started to rain and we continued to drive along the highway and the rain stopped, the road was dry, and I looked back and saw behind the veil of rain. So I understand what it means to "places".

I got several times was: the food in the car on the road, and 1 half the road is wet, the other dry

I worked in the city centre, and often it happens that in the centre it was raining, and come to the village, there is not dripped. Or Vice versa - in the center is dry, but at home it was raining.
