Any actual meteorologist will 100% back up what I'm saying. Strength of reliability of forecasting inherently goes down over time, because weather is quite literally chaotic and there's so many incalculable variables that break down forecasting accuracy given some time.
Of course models will still will output predictions, but you should not be taking them so seriously more than a few days out. No model in existence can give reliable regionalized precipitation forecasts five days out. It is a quite important, and honestly quite basic, fact to understand.
