Low-pressure systems form under areas of wind divergence that occur in the upper levels of the atmosphere (aloft). The formation process of a low-pressure area is known as cyclogenesis. In meteorology, atmospheric divergence aloft occurs in two kinds of places:
Local Weather Forecast Offices (WFO) of the National Weather Service may issue a Special Weather Statement to alert of a specified hazard that is approaching or below warning or advisory criteria, that does not have a specific alert product code of their own (such as for widespread funnel clouds with limited to no threat of complete tornadogenesis, the likelihood of landspouts, or strong ...

A weather front is a boundary separating two masses of air of different densities, and is the principal cause of meteorological phenomena. In surface weather analyses, fronts are depicted using various colored lines and symbols, depending on the type of front. The air masses separated by a front usually differ in temperature and humidity.
