Another warm day with mostly sunny skies and some cloud in a Northwest flow aloft. The freezing level will spike today getting close to 3000 meters. Some cloud will spill in from the rather active front in northern B.C., which slowly slides closer to our zone over the next couple of days. A short wave trough reaches the South Coast early Saturday morning with a brief impulse of moisture before quickly exiting and the ridge rebuilds. The blocking pattern continues into next week.
