In addition, the winds normally shift from out of the southwest to the northwest following a cold front. Thunderstorms may develop ahead of the cold front in the warm, tropical airmass. The added lift of the air due to the front adds to the storm potential. A warm front means that the warm air to the south is pushing out the colder air. A steady area of rain from nimbostratus clouds is often ahead of the warm front.
Winds shift from the east to the southwest.
Dew points often rise after the warm front with tropical air moving into the area. A stationary front is not moving. Since a frontal system is the separation of two different airmasses, near a stationary front the airmasses are of equal strength on either side of the front. As a result the weather doesn't change much and if you happen to be close to the front, rainfall can stay around for many days. The stationary front often changes into a cold and warm front when a low pressure system forms along it.
