We can expect light rain showers this afternoon with the FL rising to 2200 meters. A cold front will pass through into tonight and the FL should drop to around 1200 meters. A weaker frontal band arrives for Sunday with light showers and the FL hovering in the 1700 meter range. Monday is looking unsettled before an upper level trough sends a series of fronts through the area next week.
