Final answer:
Dewpoints in Arkansas, Alabama, and Tennessee are C. lower, indicating less humid air compared to the higher dewpoints and more humid conditions in the warm sector of the cyclone.
Step-by-step explanation:
When comparing surface moisture conditions around a cyclone, dewpoints for stations in Arkansas, Alabama, and Tennessee are generally lower than those in the 'warm sector' of the cyclone. The 'warm sector' typically refers to the area south and east of the frontal boundaries of a cyclone, over the warmer waters of the Gulf of Mexico, where dewpoints are higher due to increased moisture content. Thus, the surface air in Arkansas, Alabama, and Tennessee was less humid than the air in the warm sector of the cyclone.
The surface moisture conditions around the cyclone can be compared by analyzing the dewpoints for stations in Arkansas, Alabama, and Tennessee. In this case, the dewpoints for these stations are generally lower than those in the 'warm sector' of the cyclone where there are stations in the Gulf of Mexico south and east of the fronts. As a result, the surface air in Arkansas, Alabama, and Tennessee is less humid than the air in the warm sector of the cyclone.
