Weather-Driven Demand (WDD) is the measured impact of weather on comp sales (“lift” or “drag”).  It is a numerical representation of the consumer need for a product or service caused by perceived changes in the weather at a time/location intersection.  It does not include any factors other than weather (e.g. price, competition, etc.)  WDD is expressed as percent change from the previous year, either favorable (positive) or unfavorable (negative) for each product or service.
