Forecast Discussion
Low pressure that brought a decent shot of snow to the higher summits will continue to pull away to the northeast today. Wrap around moisture from the low will keep light snow falling early this morning before tapering to snow showers this afternoon. The summits will likely break from the clouds later today as high pressure builds in overhead and mid and upper levels begin to dry out. A strong northwesterly flow will filter in a much colder airmass from central Canada through the forecast period. This means that high temperatures will occur this morning and temperatures will fall through the day. The combination of strong winds and decreasing temperatures will prompt a wind chill advisory to be in effect from noon today through the forecast period. Wind chills today will be around 20-25 below early, then decrease to 30-40 below late. A wind chill warning will be in effect overnight through tomorrow morning. Wind chills overnight will become dangerously cold at around 40-50 below early then further decreasing to the range of 50-60 below by morning. A lowering inversion tonight may create some undercast conditions by trapping residual moisture in the mountain valleys and this may last into tomorrow. The summits will see mostly clear skies overnight as high pressure continues to build over the area. Tomorrow will be a mostly sunny day but donâ€Öt be fooled because Wind chills will still be very cold at 50-55 below early and moderating slightly to the range of 40-45 below for the rest of the day. With plenty of accumulated snow on the ground, the increase in winds will create a lot of blowing and drifting snow which will make for poor visibility above treeline.
