Cold fronts normally occur when a huge mass of cold and chilly air meets a mass of warm air, and the chilly air starts advancing on the warm air.
As soon as the cold front passes, the weather temperature starts becoming cooler and can drop by 4 degree Celsius or even more.
It can also bring rain, thunderstorms or gusty winds. The cold fronts move twice as faster as compared to the warm fronts.
The cold air is extremely dense, which provides it with the capability of moving ahead quickly and plow the mass of warm air that is in front of it.
Warm air that is lifted up produces the cumulus clouds as well as thunderstorms. The atmospheric pressure also starts changing to a great extent. Thus, the cold front makes an area cooler.
Type of Weather Associated with Cold Fronts
You will hear the weather forecasters talking about the cold fronts that are either entering or leaving a particular area.
During these times, people have to brace themselves for the cold weather that is on its way.
Therefore, it is extremely relevant for you to understand the type of weather that is normally associated with the cold fronts.
On the weather charts or the synoptic charts, these cold fronts are represented by solid lines.
Before the Cold Front
When a cold front has been forecasted for the area where you reside, the weather is going to face several changes.
These changes include the winds moving from South to the southwest. The temperature will also start changing significantly and drop as the cloud starts accumulating.
You may also experience periodic showers, easy visibility, and a higher dew point.

Heavy rains can be accompanied by hail, lightning, and thunder. The cumulonimbus clouds can be spotted when a cold front tends to pass from your area.
Hazy visibility will remain and will clear only as the front passes away from your area.
After the Cold Front
As soon as the cold front clears away from your area, the winds will start shifting towards the north-west, while the temperature will remain cold.
It will continue raining because of the presence of the cumulus clouds, which are flat in nature. The air pressure keeps rising constantly.
With time, the showers subside, and the visibility also starts getting clear.
The cold fronts are normally associated with rapid movements of cold air, which in turn is connected to severe and harsh weather.
Thunderstorms are capable of destroying everything on their way. And, most of the times, it has been observed that a cold front can lead to rain, thunderstorm, and hail storms, which lasts for about 2 to 3 days.
More about Cold Fronts
Cold fronts lead to a huge change in the moisture content of an area. The moisture content becomes high in the front, and it becomes slow behind it.
The shifts in the direction of the wind can be identified easily. When the cold front enters your area, the winds start moving in the northern direction.
It has also been observed that the cold fronts can extend from one area to another because of the extended pattern of weather that they follow.
For example, they can start in Canada, and move to locations that are far away, like Oklahoma. This describes one of the most interesting characteristics that is associated with a cold front.
The Wrap Up
Cold fronts can be identified easily by the weather forecasters as they have a huge presence on the radar and they generate massive differences in the weather.
However, cold fronts are considered to be a blessing if the temperatures have been extremely hot in an area.
The rain and thunderstorms that it brings help in relieving the people. On the other hand, cold fronts in areas that are extremely cold can lead to severe temperature drops.
This is why it proves extremely important to prepare yourself if you see on the news or hear on the radio that a cold front is approaching.
Always try to and stay protected from the huge temperature drops and heavy showers.
