To identify the possible conditions in Chicago when a snowstorm was predicted, we need to find the row in the table where the air pressure is below the normal atmospheric pressure, which is 29.9 inches of mercury.

Let's analyze the table:

1. First row:
- Upper Air Temperature: 36°F
- Surface Temperature: 45°F
- Air Pressure: 28 inches of mercury

The air pressure is 28 inches of mercury, which is below the normal atmospheric pressure of 29.9 inches of mercury.

2. Second row:
- Upper Air Temperature: 40°F
- Surface Temperature: 29°F
- Air Pressure: 30 inches of mercury

The air pressure is 30 inches of mercury, which is above the normal atmospheric pressure of 29.9 inches of mercury.

3. Third row:
- Upper Air Temperature: 30°F
- Surface Temperature: 75°F
- Air Pressure: 32 inches of mercury

The air pressure is 32 inches of mercury, which is above the normal atmospheric pressure of 29.9 inches of mercury.

Based on these analyses, only the first row meets the condition of having an air pressure below the normal atmospheric pressure. Therefore, the possible conditions in Chicago when a snowstorm was predicted are:

- Upper Air Temperature: 36°F
- Surface Temperature: 45°F
- Air Pressure: 28 inches of mercury
