Inversion break Tomorrow, But More Foggy Days and Melting Mountains Ahead...Jan 20th

  • A high pressure system will remain stationed over much of southern BC this week leading to foggy and cool weather along the coast & valleys, but blue skies and warm temps above
  • The inversion layer is building for today, and will pick up again Wednesday through to next week, helping to lock morning fog and cooler temps in for the coast and valleys
  • Some mixing is helping to clear skies out this afternoon for a mix of sun and cloud but fog will redevelop again tonight
  • Tomorrow we will have a good chance of clearing out as we loose the inversion for one day leading to a good mix of sun and cloud in the afternoon thanks to a little system that may also bring a few afternoon showers, but then the ridge re-strengthens starting Wednesday = harder for fog to clear out
  • The pattern looks to continue right through to the weekend before weakening early next week.. temperatures in the low to mid-teens will continue to be the story above 1500 m
