Temperatures dropped and with all that moisture trapped at the surface, some dense fog developed last night & this morning.
That'll stick around until temperatures start to warm up.  
Sunrise is at 7:43.  So, the fog probably won't start lifting and dissipating until after 8am.
Once it burns off...we'll get a warm & sunny St Patrick's Day across most of Central and North-Central Alberta.

Heading into the last weekend of winter -
Snow is expected to roll through northern Alberta on Saturday with the possibility for heavy snow in the High Level region.
Parts of NE Alberta may also see several cm of snow.
Areas like Grande Prairie, Slave Lake and Bonnyville should get SOME precip.  But, it doesn't look like it'll be a heavy snow event for those areas.
