Going south to be in the north

Today we made the two hour jouney from Chester to Northampton for lunch with my husband's family. Chester was cold but bright when we left this morning. Northampton had had snow over night and felt bitter by comparison with Chester and it sleeted whilst we were there. My husband's brother-in-law commented that Northampton must feel positively tropical by comparison with Chester. He was rather surprised when we informed him that we had not had snow in Chester and the temperature was several degrees warmer.
