Persistent Valley Cloud
A stagnant airmass will continue to be present over BC for today and tomorrow thanks to the persistent ridge of high pressure. This means low cloud and fog will persist over areas along the BC coast and valley cloud in many interior valleys.
The next system weather system to threaten BC will be Friday. However, the ridge will be still strong enough to protect the BC interior and south coast ranges. The Northwest ranges may not be so lucky as the ridge deflects the system towards the Northwest/Yukon. Snow and wind can be expected when the front does arrive to those regions.
The 500 mb animation depicted above shows a significant ridge over BC which acts to shield the province from any mid-high cloud or precipitation. On Friday, the ridge will shift far enough to the east and open the door for the next weather system to hit the coast.
