 ====== Overrunning ======
-Overrunning is where two air masses overlap each other, resulting in precipitation. This is mostly applied to winter weather discussions where a cold air mass overruns a warm one, resulting in the Northern end of the system supporting snow and the southern end supporting snow. These systems can produce large swaths of snow over several hours, which results in several inches of snow.
+Overrunning is where two air masses overlap each other, resulting in precipitation. This is mostly applied to winter weather discussions where a warm air mass is forced above a cold air mass at the surface, resulting in stratiform precipitation where the northern part of the precipitation shield is snow. These systems can produce large swaths of snow over several hours, which results in several inches of snow.
