The Science:   High pressure will build over the region today with a dry, cool ENE flow pattern developing.  Temperatures will slowly warm over the next few days as the pressure ridge slowly drifts through.  

The next system of interest enters the region over the weekend.  The northern jet stream takes aim at the PNW from the NW.  This should allow cool unstable NW flow to bring some snow our way.   This is still a ways out for models to agree on the details, so stay tuned as things develop.
