Cold fronts typically associated to showers and storms,
while those associated with warm fronts typically have
areas with lots of cloudiness, extensive cloud cover.
And some areas of precipitation, which may be generally stratiform,
It means that it falls in a continuous but not very intense way.
And another very defining thing of the fronts is
the variation in the direction of the wind.
The wind before and after the front will change,
You know that because it was visible in the isobars.
Associated to the front, typically before a front we will find
Southwest, after the front we will find the north-west,
typically associated with the change of a cold front.
While on a warm front the difference is not so marked,
here it is more difficult to know when the front has passed,
before we will usually have more southern winds, and here they will be more from west.
But that will depend a lot on how this warm front is configured.
In addition, the warm fronts are very well defined in high latitudes, above
the fifty degrees, sixty degrees, there they will behave well because the
difference between the masses of cold and hot air are going to be very distinct.
But at lower latitudes, toward the 40 degree latitude,
the warm fronts typically pass very blurred,
and are a bit more difficult to monitor.
