Warm Occlusions.

  In the warm occlusion, the relatively cooler air rides 
up over the cold air.  This results in a cold front aloft.
In analysis, if the air ahead of the warm front is 
colder than the air behind the occlusion, then it is a 
warm occlusion.  Both the Type A and Type B PFJ 
configurations occur with warm fronts.

	On the surface, temperatures are cold ahead of 
the front, warming after passage.  Surface dew points 
rise after passage.  Visibility and weather is usually 
poor before and during passage and improving after 
passage.  Ahead of the front, pressures will fall with 
the lowest pressure occurring right during passage.  
Following passage, pressures rise.  Surface winds can be 
gusty, usually from the south to southeast before passage,
rotating clockwise to the west - northwest after passage 
(veering winds).
