Is it possible to include covariates representing future prediction periods?

[yawen-714]

Suppose the time series I want to predict is Series A. I input the historical three-day data of Series A to predict the next day's values of Series A. I would like to know if I can incorporate the next day's values of Series B as a covariate to improve prediction accuracy. For example, I want to input historical three-day photovoltaic (PV) power data along with the next day's weather forecast to predict the next day's PV power generation
