An upper level trough of low pressure is sending storms in waves at the Pacific Northwest. That means a more wet weather  ahead. Another  disturbance will march through getting us even wetter. By Friday a new frontal system will be approaching the coast. Low snow levels will keep new snow falling in the mountains which will increase the snow depth so there will be more water available as spring runoff to raise the levels of the reservoirs.
