Washington Cascades Weather- Extended

Updated April 24, 2013
Several more days of a ridge of high pressure then we will have a return to troughs of low pressure moving and in out of our region. The map below for May 4 indicates a trough of low pressure off the Washington coast and this would tend to bring below normal temperatures and above normal precipitation.
