Weather Synopsis for Thursday & Sunday
The Pacific Northwest is experiencing a period of generally quiet and continued unseasonably cool weather.
A piece of upper-level energy, clouds and light snow rotated north into Canada Wednesday night, leaving the weak parent low spinning offshore. We are forecasting more sunshine than previously expected with mostly clear or partly cloudy skies in many areas. A band of clouds and light shower activity in the near-shore waters may rotate into the Mt. Hood area late this afternoon and evening, bringing an inch or so of snowfall there. Elsewhere, expect Thursday night to have very cold surface temperatures under clear skies and light winds with inversion conditions developing, particularly east of the Cascade Crest.
The offshore low will drop SE on Friday into Oregon by Friday evening. The March sun will warm most areas by Friday afternoon and inversion conditions are not expected to persist. Freezing levels should approach pass level in the afternoon.
