Enter Lake Temperature: oC view the definition. An old rule of thumb for lake effect snow forecasting is that the difference between the lake water temperature and the 850 mb temperature must be at least 13 degrees C (approximately the dry adiabatic lapse rate) for lake effect snow to occur. Lake enhanced snow can occur with a differential of about 7 degrees C. The larger the difference between the lake water temperature and the 850 mb temperature, the larger the instability. However, there are times when the lake water / 850 mb temperature difference exceeds 13 degrees C, and little if any lake effect snow occurs. For an explanation of this, see the section on dendritic depth.
