Snow showers and flurries linger into Thursday; Clipper (Light snow) late Fri-early Sat

/Issued 5:10 PM CST, Wednesday, December 28, 2016/

A clipper system looks like it will pass through the Northland late Friday afternoon through early Saturday morning.  A swath of 1-4" of snow is expected in our area as this low pressure system moves through.  Note:  The greatest snow totals should fall north of Duluth the way it looks now.  The track of this clipper could change a bit before Friday, and the 2-4" snow area may need to be adjusted a little more south or north depending on the track of the low.

Here's a look at today's system which brought some snow to northeast Minnesota and northwest Wisconsin.

Lake effect snow showers are expected to develop on Thursday along the South Shore of Lake Superior affecting Iron County where a Lake Effect Snow Advisory is in effect from Thursday morning through Friday morning -- More information at this link

After the late week clipper, attention will then be drawn to our west and southwest as that is where our next system could be coming from for early next week.  Still some model differences with this one so stay tuned.

Weather Synopsis:

A fairly strong upper level disturbance moved across northeast Minnesota and northwest Wisconsin today, this disturbance combined with a warm front and cold front which also moved into the upper Midwest generated enough lift in the atmosphere to produce widespread snow showers today.  Snowfall amounts have generally been around 1" or less but a few locations up north have picked up around 2.0"-2.5" of new snow today.  Warmer temperatures moved into the area today with highs in the mid to upper 20s with low to mid 30s stretching from Longville to Hinckley to Siren and southwest from there.

*Snow showers and flurries will linger across the Northland tonight with snowfall amounts generally less than 1".  Strong height falls of 120-150 meters/12 hours accompanying today's system will exit off to the east during the night but additional energy approaching from the NW should keep some snow showers going early this evening, and then again overnight.  Lows will be in the teens and 20s.

*A few snow showers and flurries will continue in northeast Minnesota and northwest Wisconsin on Thursday otherwise expect mostly cloudy to partly sunny skies with highs mainly in the 20s.  Gusty west or northwest winds at 15 to 30 mph.
