Final answer:
Sarah should expect colder temperatures, increased wind, and potential precipitation such as snow or freezing rain due to the incoming cold front and high humidity.
Step-by-step explanation:
When a cold front moves into an area with a high temperature of 24°F and a relative humidity of 93 percent, Sarah can expect a significant change in the weather. Cold fronts are often associated with rapid drops in temperature and atmospheric pressure, leading to increased wind speeds, a shift in wind direction, and a potential for precipitation, which could manifest as snow or sleet given the freezing temperatures.
The presence of high humidity indicates a substantial amount of moisture in the air, which may lead to the formation of heavy dew, snow, or freezing rain as the temperature drops. Therefore, Sarah should be prepared for colder, possibly slippery conditions and potential roadway hazards along with a chance of precipitation in the form of snow or freezing rain.
