The cold upper level trough retreats to the north as high pressure builds in, allowing winds to shift from northwest to southwest by Sunday.

Saturday remains cold.  Some mid level clouds early, then mostly sunny, the some clouds late afternoon.  High 42.

A strong southwesterly wind brings mild temperatures and sunny skies Sunday.  It will be breezy.  High about 55.

As mentioned earlier this week, model continuity remains poor, so forecast specifics remain uncertain beyond a few days out.  One forecast aspect seems to have consistency — expect large swings in temperatures every few days.
