Dangerous weather conditions can be indicated by sudden visual changes in the clouds, a strong movement of wind or other sensations. Some people can even feel pain in arthritic joints as pressure changes occur.
A red "L" on a weather map typically denotes a low-pressure system. This indicates an area where air is rising, leading to the possibility of cloudy skies, precipitation, and potentially stormy weather conditions.
In general high pressure indicates good weather and low pressure indicates storms.
Severe weather refers to extreme or dangerous weather conditions, such as hurricanes, tornadoes, blizzards, or severe thunderstorms. These conditions can include high winds, heavy rain or snow, hail, and lightning, and can pose a threat to life and property.
Pressure, on it's own, does not indicate any particular weather. It is the changes in air pressure, along with other factors such as humidity etc which indicates the proposed weather changes.

A storm watch indicates that a storm of a given type may be possible in your area. They basically inform people to be on alert for dangerous weather conditions.
If the visibility is good, it indicates that there are no significant weather conditions affecting visibility, such as fog, rain, or snow. Generally, in such cases, the weather is likely to be clear with little to no cloud cover. However, the exact weather conditions and temperature can vary depending on the season and location.
In general high pressure indicates good weather and low pressure indicates storms.
A tornado watch indicates that general weather conditions favor development of tornadoes.
A blue line with blue triangles on a weather map represents a cold front. This indicates the leading edge of cooler air moving into an area, typically associated with a shift in weather conditions such as a drop in temperature and the possibility of precipitation. The triangles point in the direction the front is moving, signaling where the cold air is advancing.
Blue on a weather forecast typically indicates cooler temperatures or the possibility of precipitation, such as rain. It can also be used to represent areas with fog or mist.
If general weather conditions favor the formation of tornadoes then a tornado watch is issued.
Severe weather refers to extreme or dangerous weather conditions, such as hurricanes, tornadoes, blizzards, or severe thunderstorms. These conditions can include high winds, heavy rain or snow, hail, and lightning, and can pose a threat to life and property.

"Serve weather" seems to be a typo or a mistaken phrase. It is likely meant to be "severe weather," which refers to extreme or dangerous weather conditions like hurricanes, tornadoes, or blizzards.
