Cold air masses tend to move slower than guidance due to impedance at the surface

Isentropic lifting produces more homogeneous precipitation amounts than does convection and can help to make ‘bolder’ forecasts

In a developing cyclone, patches of dry air still wrap around the incipient wave causing breaks in the clouds.

Diabatic effects of the warm lakes will tend to steer the colder air away from a site surrounded on three sides by water.

The center of low pressure is an area of weaker winds and it takes awhile for the winds to pick-up.

In an increasingly windy, cold-advection environment, low clouds are common, but low visibility is not.
