WARM FRONT SHIELD - WEATHER EVENTS

by ZAMG


Warm Front Shields are connected with multi-layered cloudiness, with overcast of low and middle level cloudiness in the warm sector. Moderate to heavy precipitation can be found well ahead of the surface front, but after front passage in the warm sector there is still slight to moderate precipitation possible.
