Can weather change 4 days?
No weather forecasts are very accurate for more than 1 or 2 days in advance.
Usually major events like blizzards and hurricanes can be tracked fairly far in advance (but even then small differences can mean you get 2″ versus 20″ or vice versa).
5 days out is too far, some forecasts within a day or two change sometimes..
