region Saturday morning. That will force the surface thermal trough into
northeastern Oregon with transport winds becoming light. The couplet will
continue east Saturday afternoon with good mixing and northwesterly transport
winds. Skies should mostly be partly cloudy with near normal temperatures and very
limited mountain shower activity. Another upper-level trough will turn the
flow aloft southwesterly Sunday with an increasing chance of showers, mainly
across the southern districts. Afternoon smoke dispersion should be good with
more northerly transport winds. A stronger system will likely bring much
cooler and showery weather Monday with snow levels dropping to near 5000 feet.<o:p></o:p></span></p>
