3. The cities listed below, from Chicago to Pittsburgh, lie in a roughly straight west to east line. Data on temperature, barometric pressure, and sky conditions for each city are shown in the table below. Use the data to explain what types of air masses are present and/or moving among these cities and how this accounts for the weather. What will Pittsburgh's weather be like within the next 24 to 48 hours?

City	Temp (oF)	Pressure (in.)	Conditions
Chicago, IL	73	29.94 rising	Clear
Indianapolis, IN	75	29.93 falling	Partly cloudy
