Question

Which will most likely result from a low pressure weather system

Answer 1

So what I've learned throughout my school life, air will rise near low-pressure areas. When the air rises it cools and usually forms clouds and with clouds might come precipitation.  

Just for fun: Warm front and cold front

Warm fronts: warm air takes the place of cold air. Usually when there is a warm front there can be dangerous weather. These usually form in the east and southerly winds push the air that is warm to the north. The warm air is above the cold air, which is denser than warm air. We all have learned, as warm air rises the vapor condenses into clouds that can produce four types of precipitation: freezing rain, sleet, rain, or snow.

Cold fronts:  most of the time when people hear the term cold front they thing of cold weather coming. That is not always true. A cold front has a warm-cold air mixture. The colder air takes the place of the warmer. You can have cold fronts in the summer. Cold fronts in the summer bring slightly cooler weather but it also brings in dryer air meaning less humidity.  A cold front in the summer can result in a thunderstorm, tornadoes, and strong winds.  In the winter cold fronts obviously bring super cold air.

Hopefully this helped and good luck.
