Also depends where you live. The weather forecasts two decades ago when I lived in the midwestern US were more accurate than they are today where I live now, on the coastline.

There are neither sensors nor radars west of the US west coast because there is no land there. Weather in the northern hemisphere tends to move from west to east. The midwest had (and still has) several days of high-quality data on whatever is incoming, and it's passing over pretty uniform terrain.
