Why does the weather on bbc website thats meant to give a 5 day forcast change every day??

Question

one day i look it is sunny all week, i book my days out with the kids ... the next day i look its cloudy and raining ?????? WHAT IS GOING ON?? we spend all this money on weather forcasting and they cant even get it right two days in a row

Answer 1

Computer models and weather data can change very suddenly. It is impossible for a meteorologist to say exactly what the weather will be 5 days from now because of this. One computer model run may show a storm system to move a couple hundred miles to our north. A few hours later, the computer model can indicate the system to go right over us. I guess that's why meteorologists normally only start out with a small rain chance near the end of the forecast because of the uncertainty. As the days get closer, depending on how the models look, they will increase, decrease, or keep the rain chances the same.

Answer 2

I have noticed this as well and have been keeping a record recently. It is more often wrong than right, sometimes they even get the weather today wrong. Why don't they look out of the window?

Answer 3

Because they are always guessing and they always get it wrong!

Answer 4

Because predicting the weather is not an exact science.

Answer 5

it is impossible to predict the wether hours in advance let alone days.

as mentioned it is an exact science and weather can differ on many scales national regional a localised.

it May be cloudy and raining where you are but 10 miles up the road it may well be a scorcher! luc of the draw!

My advice is there is no such thing as bad weather only ill prepared people, have th right clothing and get out and enjoy it what ever the weather.. and another thing..The BBC is unreliable on many fronts dont expect them to be reliable, you wont be disappoined!

Answer 6

Because wind direction and speed are constantly changing.

Answer 7

Because conditions change all the time. They can only ever make a prediction of what is going to happen and that will change depending on lots of factors.

Answer 8

English weather changeable.
