Bob , No need to as the level of historical level of demand would
already take that into account. The only time that you might consider
incorporating these kinds of variables ( which by the way would have
to be predicted themselves ) is iff you felt that there were dynamics
in these series that would change demand ( like a busload of
alcoholics due to stop near a store ) that would have an effect on
demand.
In fact if one or more of these variables had historically changed and
consequently had an historical effect on demand BUT was omitted from
the model , the ARIMA structure proxies such omitted variables. The
ARIMA proxy is quite appropriate unless future values of the omitted
cause variables are significantly different than what would have been
anticipated by THEIR PAST .
