A Cold Front On The Weather Map
Looking at our weather map above we can see a cold front moving through the states of Oklahoma and Kansas.
The major thing about a cold front is the weather it can bring with it.
The eastern side of the cold front provides two chances to receive precipitation.
The first one is known as a squall line which usually forms some 50-150 miles ahead of the cold front. The squall line can be responsible for bringing severe weather in the form of super-cell thunderstorms.
The second part of the squall line is the strong winds that can occur known as straight line winds. Sometimes they are confused as tornadoes because of the damage they can do.
As the cold front moves into the region another area of thunderstorms will form just ahead of the cold front and these can also be severe, producing tornadoes, major hail and wind damage.
Once the front passes the weather becomes clear and calm.
The winds ahead of a cold front are mostly south-southwest then turning to the northwest behind the cold front.
The temperatures are also warm ahead of the front. It is possible sometimes to see temps as warm as 90F ahead of the front and then when the front passes temps can drop over 40 degrees.
A cold front is a major feature on the weather map and can be identified with a blue line with triangles attached to the blue line.
