A fifteen-day weather outlook for the Pittsburgh, Pennsylvania area provides predicted meteorological conditions such as temperature, precipitation, wind speed and direction, and humidity.

Extended forecasts offer individuals and businesses crucial information for planning. Farmers can make informed decisions regarding planting and harvesting, while event organizers can assess the feasibility of outdoor activities. Travelers can pack appropriately and adjust itineraries as needed. While inherently less precise than short-term forecasts, these outlooks have become increasingly accurate due to advancements in meteorology and computing power. Historically, long-range predictions were based on simple observations and seasonal trends, but now sophisticated models account for numerous atmospheric variables, improving reliability. This data is vital for economic sectors sensitive to weather fluctuations, like agriculture and tourism.
