Highs near the freezing mark Monday with some light snow later in the day. Update on midweek snow event, bitter cold to follow

/Issued 6:45 PM CST, Sunday, December 17, 2017/

Note:  Still keeping a close eye on a potential snow event that could impact the Northland mid to late week.  The pattern setting up is also favorable for some lake effect snow along the North Shore of Lake Superior with east/northeast winds from Wednesday evening through Thursday, possibly lingering into Friday.  Potential does exist for up to 4 inches of snow out of this system with more than 6 inches of snow not out of the question especially near Lake Superior.  Stay tuned.

Weather Synopsis

Generally mostly cloudy skies in our area today with a few peeks of sun mixed in, but a small portion of far northern Minnesota did have a bit more sun compared to other areas this afternoon.  Highs were in the mid 20s with a few locations hitting the freezing mark!

Tonight:  Considerable cloud cover with areas of fog possible along with some patchy light freezing drizzle.  Lows will be in the teens and 20s.

Monday:  A strong area of low pressure ~982mb will move from central Manitoba Province in the morning to northwest Ontario Province by the evening -- Attached to this low will be a warm front and cold front with both of those boundaries passing through the Northland on Monday.  Patchy fog or light freezing drizzle is possible early, otherwise expect mainly mostly cloudy skies. 

There will be some snow that moves west-east impacting portions of the Northland especially during the afternoon-evening hours.  850mb and 925mb temperatures are forecast to warm to around zero to -2C on Monday, but it looks cold enough for the precipitation to fall as snow, but surface temperatures hovering near the freezing mark could lead to some sleet or even light rain, especially if the temperatures aloft warm a few more degrees than currently forecast.  Note:  The greatest potential for around an inch or so of new snow on Monday looks like it'll remain along or north of Highway 2 in northeast Minnesota.

Highs Monday will be in the upper 20s to middle 30s with lows Monday night in the 20s.  Will have a rather stiff breeze out of the SW on Monday with gusts to around 20-25 mph possible.

Tuesday:  Partly to mostly cloudy skies with a few flurries possible as a secondary cold front drops south into the Northland.  Highs will be 20s to around 30 degrees.

Note:  Bitterly cold temperatures are still expected starting next weekend and carrying over into the following week.  Still is some uncertainty on just how cold it'll get in our area with today's model data showing the coldest air staying more over the northern Plains but still plenty cold in the Northland but perhaps not as extreme as prior model runs were showing, but that could easily change in coming days.  Potential is there for daytime highs ranging from around 5 above to 10 below for Christmas Eve and Christmas Day with lows from 10 below to around 30 below possible.

Forecast for Duluth and Superior

.Tonight...  Mostly cloudy.  Patchy fog or freezing drizzle possible.  Low 20 to 25.  Wind southwest at 10 to 15 mph.

.Monday...  Mostly cloudy.  Light snow possible especially after 4 PM.  High 30 to 35.  Wind southwest at 10 to 20 mph with higher gusts possible.

Milder temperatures through Monday. Potential snow event next Wed-Thur followed by bitter cold temperatures next weekend

/Issued 5:31 PM CST, Saturday, December 16, 2017/

Source:  https://www.ecmwf.int

I'll be keeping a real close eye on the model trends over the next several days to see if there is any moderation in temperatures for the December 23-25 time frame.  Right now next weekend looks frigid! Computer models have been showing a pattern that would be favorable for bitter cold temperatures over the Northland for Christmas weekend, since we're still a week away from this, things could change just a bit, but so far there hasn't been much change in the long range computer models pertaining to next weekend's pattern/bitter cold setup.  Stay tuned














Snow is possible next Wednesday and Thursday.  Still some uncertainty on the track and strength of the surface low, but based on latest model projections, the area in blue has the greatest chance for around 3 inches or more of snow next Wednesday-Thursday.  Stay tuned

Weather Synopsis

A strong baroclinic zone is in place across the area today with afternoon 850mb temperatures ranging from -20C in northeast Ontario Province to -10C in northeast Minnesota to +2C in far southern Minnesota.  Temperatures ranged from ~0 in eastern Ontario Province to the lower 50s in eastern Nebraska.  With this temperature contrast in place, some snow has been occurring at times in parts of the Northland but snowfall amounts haven't been very heavy, generally ranging from a dusting to 2 inches.  Mostly cloudy skies covered the Northland today with highs in the teens along and north of Highway 2 in northeast Minnesota to the 20s south of Highway 2 including all of northwest Wisconsin.

Tonight:  Mostly cloudy skies with possible flurries and maybe some patchy freezing drizzle.  Snow showers will continue especially this evening along the North Shore of Lake Superior due to an east wind coming off the lake with up to 2 inches of snow possible.  Lows tonight will be in the teens and 20s.

Sunday:  High pressure will cover the upper Midwest while a warm front lifts north into Ontario Province.  Highs will be in the mid 20s to low 30s (Around 5-8 degrees above average for mid December) Looking at mostly cloudy skies once again to end the weekend, although some sunny breaks are possible.

Monday:  Strong area of low pressure ~982mb will pass well north of our area while a warm front and cold front attached to this low pass through the Northland -- There could be some snow on Monday over parts of the Northland with accumulations of a half inch to one inch possible especially north of Highway 2 in northeast Minnesota.  Highs Monday will range from the mid 20s to low 30s.

Weather Synopsis

A few breaks in the clouds at times in parts of the area today but overall skies were mostly cloudy, there's also been some pesky fluffy snow flurries as well today but little if any accumulation.  Highs today were mainly in the teens which is roughly 5 degrees below average for mid December.

Tonight:  A cold front will drop south into the Northland with low pressure over the eastern Great Lakes.  Occasional flurries will continue tonight while some lake effect snow showers develop along the South Shore of Lake Superior.  Lows ranging from around 10 below to the single digits above zero, a little warmer along the South Shore of Lake Superior.

Friday and Saturday:  A frontal boundary will become nearly stationary west/south of our area with high pressure to our north -- Should see some snow near and north of the aforementioned boundary with this snow most likely to develop Friday afternoon or evening, then continuing through Saturday morning before ending.  Note:  East winds will develop Friday night and continue most of Saturday which could lead to some lake enhanced snow along the North Shore of Lake Superior.  Highs Friday will be on the chilly side with temperatures in the single digits in far northern Minnesota to the 20s near the Brainerd Lakes area.  Highs Saturday are forecast to range from the mid teens to mid 20s.

Note:  A frigid weather pattern has been showing up now fairly consistently per long range models for December 22-25 this would include Christmas Eve and Christmas Day.  How cold? Still a little early to say with a lot of confidence, but the potential is there for daytime highs around zero with overnight lows ranging from 5 below to 30 below, certainly could end up even colder, or could trend warmer in coming days.  Stay tuned

Radar loop ending at 4:35 PM CST, December 13, 2017.  Lake effect snow showers continued late this afternoon but this band which had been impacting the North Shore most of the afternoon is starting to shift more to the South Shore as winds shift out of the north.  Note:  Expect lingering snow showers in Duluth until around 6 PM with less than an inch of additional accumulation.  Roads are in bad shape in the Twin Ports area so use extreme caution if you have to travel tonight.
















Note:  Winter Weather Advisory in effect until 6 AM CST Wednesday for Bayfield, Ashland and Iron County along the South Shore of Lake Superior in northwest Wisconsin.  Snowfall of around 2 inches is expected with snow covered and slippery roads and reduced visibilities at times.

Here's a water vapor satellite loop of today's storm system that impacted portions of the upper Midwest and Great Lakes. 
















Note:  Forecasting these winter weather events is always a challenge, sometimes the forecast will bust too high or too low on snowfall amounts.  Lake Superior played a role in producing more snow in parts of Duluth and Superior today than what was forecast to fall - The clipper itself also tracked a little farther north, and the resultant snow band from that clipper also ended up a little farther north than what was expected.  Snowfall amounts from this clipper were higher than what was forecast for east central Minnesota into parts of northwest Wisconsin earlier today.  Oh the joys of winter weather forecasting!

Weather Synopsis

Low pressure of 994mb was over southern Lake Michigan at 3 PM today with an area of 120 meter 12 hour 500mb height falls covering much of the upper Midwest and western Great Lakes this afternoon.  Snow continued to fall late this afternoon mainly around Lake Superior where good convergence, and a good contrast between 850mb temps and lake water temps has produced a fair amount of lake enhanced/effect snow today along the North Shore of Lake Superior, the setup for this lake effect snow is starting to become less favorable though as of late this afternoon as winds shift around from the E-NE to the N.

Tonight:  High pressure builds in from the north while low pressure tracks from southern Lake Michigan toward Washington D.C.  Snow showers will persist through the night along the South Shore of Lake Superior while flurries and snow showers over other parts of the Northland diminish this evening.  Lows tonight ranging from around 10 below to 10 above zero.

Thursday:  Could see a few flurries or light snow showers at times as a weak low pressure system passes north/east of the Northland while dragging a cold front through our area Thursday night.  Highs will be in the teens to around 20 degrees.

Note:  The next best chance for perhaps an inch or so of snow comes Saturday as an area of low pressure tracks east out of the northern Plains, more on this tomorrow.

Forecast for Duluth and Superior

.Tonight...  Snow showers and flurries ending this evening otherwise partly to mostly cloudy skies.  Low 4 to 9.  Wind north to northwest at 10 to 15 mph.

.Thursday...  Partly to mostly cloudy.  Snow flurries possible.  High 15 to 20.  Wind west at 10 to 15 mph.

Note:  Low pressure of 1002mb over western Manitoba Province this evening will drop southeast, reaching southern Minnesota Wednesday morning, then will see this low head into northeastern Indiana by Wednesday evening.  As the low drops SE it will deepen with a pressure falling to ~996mb.  This system will continue to produce light snow at times over northeast Minnesota and northwest Wisconsin through Wednesday.  There could also be some patchy light freezing drizzle/light freezing rain later tonight through Wednesday morning especially over western/southern sections of the Northland.  Easterly wind coming off Lake Superior combined with cold air in place will also cause some lake enhanced/lake effect snow especially on Wednesday along the North Shore of Lake Superior.  The potential for North Shore lake effect snow will decrease by late Wednesday afternoon as winds shift to the north.
