We all are and I guess as long as new science comes along and people develop bigger and better models etc, we will keep on learning. I still only have a very small % of the knowledge of many on here (and a few more hunches TBH) and really enjoy the forecasts and explanations given by our more experienced members who have been studying meteorology for years.
100 years ago people were using seaweed and pine cones to guess what the weather might be the day after. Today we look at charts produced by supercomputers to tell us broadly what's going to happen in 5 days time. Who knows how accurate we will be in 100 years time?
