Hello ,

i am trying forecast weather for one city. I got data from multiple cities and i want to do multilocal weather prediction.

Parameters in database i have: temperature ,humidity, pressure,wind speed,wind direction and clouds (number value +name).

How i imagine this: after running program multiple plots will show up. One for temperature,one for pressure ,etc. In plot will be old data and then predicted data different color. Basically all i want to do is predict future data from old data.

What i already did: I tried several examples from System Identification Toolbox. But i had some problems with iddata function or plot doesn't went like i wanted. I attach matlab file with my try of predict humidity. I was thinking about changing model for ARMAX or something like that.

This is what i get from my code i attach: Snímka.PNG
