Still keeping an eye on next Monday and Tuesday, this is when we could get our next decent snow event in northeast Minnesota and northwest Wisconsin.  Still quite a bit of model disagreement though so stay tuned for new updates over the weekend.

Weather Synopsis:

An area of low pressure has moved into northeast North Dakota this afternoon with strong 12-hour 500mb height falls 90-150 meters covering the northern Plains per mesoanalysis.  A strong thermal gradient is in place for today’s clipper with late afternoon 850mb temperatures ranging from +5 C in far southwest Minnesota to -12 C in far northeast Minnesota.  3 PM temperatures ranged from the 50s and lower 60s in central Nebraska to the teens across northern Minnesota.

Partly to mostly cloudy skies this morning across the Northland gave way to mostly cloudy skies this afternoon with some snow affecting portions of the area as low pressure approaches from the northwest.

*Light snow tonight as low pressure tracks from eastern North Dakota to north of Green Bay, Wisconsin by daybreak.  Winds to the north of this low will be out of the east for most of the night, this will result in some lake enhanced snow tonight along the North Shore of Lake Superior.  Lows will range from the single digits below zero in far northern Minnesota with teens in northwest Wisconsin and around Lake Superior.

*Tonight’s clipper will head into eastern Canada on Saturday — Lingering snow showers and flurries are possible early in the morning otherwise expect partly to mostly cloudy skies during the day.  A cold front approaching from the northwest could cause some snow showers Saturday night mainly in northern Minnesota.  Highs on Saturday will be in the teens and 20s.

Forecast for Duluth and Superior

.Tonight…  Occasional light snow.  Total snowfall accumulation of 1-2″.  Low 11 to 16.  Wind east at 10 to 15 mph becoming north to northwest after midnight.

.Saturday…  Flurries possible early otherwise partly to mostly cloudy skies.  High 16 to 20.  Wind northwest at 10 to 20 mph becoming southwest in the afternoon.

Normal temperatures for Saturday

High:  19
Low:     3

Sunrise Saturday:  7:54 AM CST
Sunset Saturday:   4:30 PM CST


Snow returns late Friday afternoon/night (Couple inches) More snow next Mon-Tue; Arctic air to follow

Here’s my snowfall accumulation map for Friday PM-early Saturday AM.  Note:  I may have to adjust the 3-5″ and 1-2″ zones a little bit more to the south by later this evening or tomorrow morning as the computer models have trended slightly more to the south with the track of Friday’s clipper.

Lake Effect Snow Advisory remains in effect until 6 AM CST Friday for Iron county in northwest Wisconsin.  More information at this link

Weather Synopsis:

Low pressure moved into eastern Canada today but a cyclonic flow on the backside of this low combined with some upper level disturbances rotating south/east across the upper Midwest kept snow showers and flurries going over the Northland today along with mostly cloudy skies although there have been a few peeks for sun every now and then.  Highs were in the 20s so not very cold as we get toward the end of the month.  West or northwest winds at 10 to 20 mph with higher gusts did put a little chill in the air though despite the relatively ‘mild’ late December temperatures.

*Snow showers and flurries continue in parts of northeast Minnesota and northwest Wisconsin this evening with accumulations less than 1″.  Mostly cloudy skies with some clearing expected to develop as the night wears on as high pressure exerts its muscle into the Northland.  Lows tonight will be in the single digits below zero to around 10 above.

*Some sunshine is possible Friday morning but clouds will be on the increase as low pressure approaches from the northwest — Snow will spread into western portions of the Northland Friday afternoon, the snow will then push farther south/east and should cover most of northeast Minnesota and northwest Wisconsin by early Friday evening.  Snow ratios are forecast to be in the 10:1 to around 20:1 range with this event so generally a fluffy snowfall is expected.  Highs on Friday will be in the teens and 20s.

Forecast for Duluth and Superior

.Tonight…  Snow showers and flurries during the evening.  Partly to mostly cloudy.  Low 5 to 10.  Wind northwest at 10 to 20 mph.

.Friday…  Some sunshine possible in the morning followed by increasing cloudiness.  Light snow developing mainly after 4 PM.  High 16 to 21.  Wind west around 10 mph becoming southeast in the afternoon.

.Friday night…  Light snow.  Total event accumulation of 1-2″.

Normal temperatures for Friday

High:  19
Low:     3

Sunrise Friday:  7:54 AM CST
Sunset Friday:   4:29 PM CST


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 Tidbits for Duluth, Minnesota

*17 days so far this month with at least 0.1″ of snow — The average for December is 13 days.  Only 4 days this month without any measurable snowfall (Trace or more)

*Snowfall total is up to 19.5″ this month (Thru 4 PM, Dec 28)  +3.7″ above normal

*Annual snowfall total is at 27.6″; -4.3″ below normal

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.

Forecast for Duluth and Superior

.Tonight…  Partly to mostly cloudy.  Snow showers or flurries early, and then again after midnight.  Snowfall accumulations less than 1″.  Low 20 to 25.  Wind west to southwest at 10 to 20 mph.

.Thursday…  Considerable cloudiness and breezy.  A few snow showers or flurries.  High 20 to 25.  Wind northwest at 10 to 20 mph with higher gusts.

Normal temperatures for Thursday

High:  19
Low:     3

Sunrise Thursday:  7:54 AM CST
Sunset Thursday:   4:29 PM CST


Milder temperatures return Wednesday (Highs in the 20s to around 30) Snow showers/flurries late tonight-Thu; More snow chances Fri PM-Sat AM

/Issued 4:49 PM CST, Tuesday, December 27, 2016/

Still keeping an eye on a clipper for late this week; Based on the current track there should be some light snow in most of the Northland with accumulations generally in the 1-3″ range in most of northeast Minnesota and northwest Wisconsin.

Recap of the powerful Christmas storm; Snowfall and storm reports in this post. Keeping an eye on a late week clipper, and possibly a bigger storm for early next week

/Issued 7:52 PM CST, Monday, December 26, 2016/

The next chance for a potentially significant amount of snow looks to be early next week, around the 2nd-3rd, of course with it being about a week away the storm track and snow area will probably shift around a bit in coming days.

Looks like will be dealing with some arctic air (Subzero temperatures) by the middle of next week, until then temperatures don’t look terribly cold as we close out the month of December on Saturday.

Summary of the Christmas storm 2016

A powerful area of low pressure tracked northeast out of Colorado and into western Minnesota between Sunday morning and Monday morning, December 25-26 — This storm brought widespread strong winds to the northern Plains and upper Midwest with wind gusts of 40-70+ mph reported in parts of Nebraska, South Dakota and Minnesota.

A blizzard hit portions of the Dakotas with major interstates shut down due to the dangerous winter weather conditions.

This storm brought a wintry mix of sleet, freezing rain and snow to northeast Minnesota and northwest Wisconsin from late Sunday afternoon through early Monday morning with a few inches of sleet accumulation and some snow accumulation farther north.

A significant ice storm affected portions of east central Minnesota, especially around the Brainerd Lakes area.

Overall I think the forecast impacts of this storm went well, however, I thought there’d be a little more snow than there was Sunday evening,  but sleet and freezing rain ended up being the main precipitation type which cut back on the snow totals especially around the Duluth area.

This week’s weather for the Northland

*Lingering snow showers and flurries with gusty winds tonight.  Areas of blowing and drifting snow will persist along with fair to poor driving conditions as roads remain snow, ice and slush covered in some parts of the area.

*Could get some breaks in the clouds late tonight and Tuesday.

*Occasional flurries/snow showers Wednesday and Thursday, not expecting much snow with this event, maybe a dusting to an inch at most.

*Clipper could affect us Friday or Saturday, if it takes a favorable track, then there could be a swath of about 1-3″ of snow for some parts of the area.
