Answer :
To predict the weather for the upcoming week based on the given data, let's analyze the trends in temperature and air pressure.
### Analyzing Data Trends
1. Temperature in the Upper Atmosphere:
- Day 1: 45°F
- Day 2: 44°F
- Day 3: 43°F
Trend: The temperature in the upper atmosphere is gradually decreasing.
2. Temperature at the Surface:
- Day 1: 61°F
- Day 2: 59°F
- Day 3: 55°F
Trend: The surface temperature is also decreasing.
3. Air Pressure:
- Day 1: 30.00 inches of mercury
- Day 2: 29.96 inches of mercury
- Day 3: 29.50 inches of mercury
Trend: The air pressure is steadily decreasing as well.
### Observations
- Decreasing Surface Temperature: We see a drop from 61°F to 55°F over three days. The significant decrease suggests a cooler trend.
- Air Pressure Decrease: The decrease in air pressure from 30.00 to 29.50 inches of mercury indicates a possible change in weather conditions such as precipitation or colder weather.
- Temperature Fluctuations: The difference between the highest and lowest surface temperatures over the three days is \( 61°F - 55°F = 6°F \), indicating a rapid decrease.
### Prediction Based on Trends
Given the decreasing trend in both surface and upper atmosphere temperatures and the steady drop in air pressure, we can infer the following:
- The drop in temperature and air pressure usually indicate approaching cold weather.
- The significant decrease in air pressure to 29.50 inches, combined with falling temperatures, suggests conditions could become very cold, potentially with clear skies or sparse cloud cover.
### Conclusion
Considering the trends and observations, the most probable weather prediction for the upcoming week is:
D. a few clouds, but very cold
This conclusion is supported by the observed decrease in both temperatures and air pressure, hinting at colder weather with minimal cloud cover.
