Goes-16 infrared satellite loop from Monday, April 29, 2019.

Today’s spring snow storm doesn’t look like much on satellite imagery, but it produced a lot of late season snow in the Arrowhead and along the North Shore of Lake Superior in northeast Minnesota.  A decent amount of lift from an approaching low and surface trough combined with additional lift due to easterly winds coming off Lake Superior helped to produce heavy bands of snow today along the North Shore.

Weather Synopsis for Northeast Minnesota and Northwest Wisconsin

I guess today was the first day of ‘second winter’ Portions of the North Shore of Lake Superior got pasted with a lot of heavy wet snow today with over a half-foot of accumulation roughly from Two Harbors to Grand Marais.  The rest of the area saw wet snow and rain today with snowfall amounts anywhere from a coating to a few inches.  Cold and blustery today under mostly cloudy skies.  Highs were in the 30s, except for low to mid 40s in far southern portions of the area from Brainerd to Hinckley, Siren and Hayward.

The setup through Thursday is rather complex but basically we’re looking at a strong area of high pressure near Hudson Bay Canada which will keep a gusty and chilly NE wind locked in near Lake Superior at least through Wednesday.  Meanwhile to our south a frontal boundary will be draped generally SW-NE from the Southern-Central Plains to the Ohio Valley/Southern Great Lakes.  Waves of low pressure are forecast to ride along this boundary through midweek.  The computer models are struggling with how much precipitation occurs in our area through Thursday.  At the very least we can expect occasional light rain, drizzle and some wet snow at times through Thursday morning, but there is a chance that a heavier swath of rain or wet snow impacts a portion of the Northland sometime in the Tuesday night-Wednesday night time frame, however, confidence is quite low on if this will even happen due to poor agreement between the various computer models.

Tonight:  Areas of light snow and drizzle will continue tonight mainly near Lake Superior, otherwise mostly cloudy skies tonight with lows in the 30s.

Tuesday:  Some light snow and drizzle at times mainly near Lake Superior.  There could also be some light rain in other parts of the area especially later in the day or Tuesday night.  Mostly cloudy to partly sunny skies Tuesday with highs in the 30s and 40s.

Forecast for Duluth

.Tonight…  Mostly cloudy.  Patchy drizzle or flurries possible.  Low 30 to 35.  Wind north to northeast 10 to 15 mph.

.Tuesday…  Breezy and cool.  Considerable cloudiness.  Drizzle or a few snow showers possible.  High 35 to 40.  Wind east to northeast 10 to 20 mph with gusts to 30 mph.

.Wednesday…  Breezy and cool.  Mostly cloudy.  Some light rain or snow possible at times.  High 35 to 40.  Wind east to northeast 15 to 25 mph.

Rain and snow on the way! Winter Weather Advisory in effect for parts of the Northland; Snowfall forecast for Monday, and a look at the top 5 snowfall totals on record in Duluth for April 29

/Issued 3:36 PM CDT, Sunday, April 28, 2019/

Winter Weather Advisory in effect late tonight through late Monday afternoon for the North Shore, Twin Ports and Arrowhead (purple shaded area on map)

…Counties included in the advisory…

Cook MN
Lake MN
Southern St. Louis MN
Carlton MN

Here’s my snowfall forecast for Monday.

•Most of the accumulation should occur on grassy surfaces and trees

•Lesser traveled/secondary roads could become snow/slush covered and slippery

•Main roads mostly wet, but there is a chance for them to become snow/slush covered and slippery if the snow falls heavily enough and for a long enough period of time, this possibility is greatest especially north of Duluth

•Reduced visibilities Monday due to falling snow.  Potential for some blowing snow especially along the North Shore where east winds could gust to around 30 mph

Should be noted that these late season snow events are very difficult to forecast.  If computer models are off by as little as 1-2 degrees in their temperature forecasts, this could lead to more rain than snow (if too cold) or more snow than rain (if too warm)  Precipitation rates also play a role, heavier precipitation rates could help cool the atmosphere causing rain to flip over to snow, while lighter precipitation rates could lead to rain being the main precipitation type.

Top 5 snowfall totals for April 29 at Duluth, Minnesota

1:  8.5″ (1989)
2:  3.0″ (1903)
3:  2.0″ (1966)
4:  2.0″ (1909)
5:  1.7″ (1994)

Note:  Dating back to 1885, there have only been 6 one-inch or greater snowfall events in Duluth on April 29, most recent was in 1994.  14 measurable snowfall events on record for April 29 (At least 0.1 inch accumulation)  Most recent was in 2002.

Weather Synopsis for Northeast Minnesota and Northwest Wisconsin

Increasing mid and high level cloudiness across the area today with filtered sunshine mixed in.  Highs today were near normal to around 5 degrees below normal for April 28 with high temps in the mid 40s to low 50s except for mid 50s along a Siren to Hayward corridor.  A rather potent system was over Montana today, and this system will be moving to the E-SE over the next 24 hours and it will bring accumulating snow and a rain-snow mix to the Northland.

Tonight:  Low pressure and its inverted trough will head east out of the Northern Plains and into the upper Midwest.  Will see precipitation gradually develop over the Northland tonight but it will take some time due to a lot of dry air with Sunday afternoon relative humidity values generally less than 30%, so it will take time for the atmosphere to saturate enough to allow precipitation to reach the surface, this should happen by late tonight/early Monday morning.  Also with the amount of dry air over the area, this will help cool the temperatures as the rain falls through this dry air, a process called evaporative cooling.  Note:  Most of us should see precipitation begin as rain late tonight, but as  temps begin to fall, some of us should see a snow-rain mix or even a changeover to all snow take place early Monday morning.  Lows tonight will be in the 30s with east winds 5 to 15 mph.

Monday:  Not a very nice spring day.  A chilly, damp and in some areas a snowy day! A weakening low and trough will move slowly across the upper Midwest Monday, this system will bring rain and snow to the Northland with precipitation lingering into Monday evening in far northeast Minnesota, while elsewhere the precipitation comes to an end during the afternoon.  Note:  Temperatures aloft are supportive of snow with 850mb temps around -2 to -4C and 925mb temps around -1 to -2C.  It will come down to precipitation rates as well as near surface temperature as to what type of precipitation you see on Monday.  Most of us should see a period of snow before Noon, then a transition to rain or a rain-snow mix before ending Monday afternoon.  The exception to this looks to be in the Arrowhead and higher terrain of the North Shore where enough cold air could remain in place near the surface allowing snow to be the main precipitation type through Monday evening.  Highs Monday only in the 30s with lower 40s toward the Brainerd Lakes, normal highs on April 29 are in the mid to upper 50s.  Gusty east winds are also expected Monday, strongest along the North Shore (20-30 mph) elsewhere we’re looking at 5 to 15 mph winds.

…Looking Ahead…

Cool temperatures should continue midweek, and there is another opportunity for some rain and snow sometime between Tuesday-Thursday, but there is low confidence on the timing and how everything sets-up during the mid week time frame.  Stay tuned.

Weather Synopsis for Northeast Minnesota and Northwest Wisconsin

A breezy and cooler day compared to how mild it’s been lately, but highs today weren’t bad for late April with temperatures topping out in the upper 40s to middle 50s which is near to a few degrees cooler than average for April 26.  Scattered clouds were seen on Goes-16 satellite imagery today passing NW-SE across north-central Minnesota otherwise skies were mainly sunny today.  Winds were out of the northwest at 10 to 20 mph with gusts to around 30 mph.

Tonight:  Partly to mostly cloudy with lows ranging from the lower 20s to lower 30s.  Northwesterly winds will shift to the north/east overnight.

Saturday:  Low pressure tracks east/southeast out of the Western High Plains and will remain well south of our area.  Will have dry weather in the Northland Saturday under partly to mostly cloudy skies.  Highs will be in the upper 40s to middle 50s, similar to the highs we saw on Friday, but it will be cooler near Lake Superior.  North or east winds are expected at 5 to 15 mph.

…Looking Ahead…

Most of the day Sunday looks dry with highs in the 40s to lower 50s.  Chances for snow or rain look to increase across the area Sunday evening with precipitation lingering overnight into Monday morning.  Low pressure moving east out of the Northern Plains will create enough lift in the atmosphere to produce at least some precipitation later Sunday.  Although temps will be mild Sunday, evaporative cooling will occur Sunday evening with temps aloft cold enough for frozen precipitation, so once the near surface temps become cold enough, precipitation will fall as snow.

Note:  Some parts of the Northland could see a half inch to 2 inches of slushy snow late Sunday night/Monday morning.

Some more rain or snow is possible next Wednesday-Thursday, May 1-2.

Forecast for Duluth

.Tonight…  Mostly clear this evening.  Partly to mostly cloudy overnight.  Low 30 to 35.  Wind north to northwest 10 to 20 mph becoming northeast.

.Sunday night…  Rain and snow.  Snowfall accumulations of up to an inch possible.  Low 31 to 34.  Wind east 10 to 15 mph.

By no means is this a very strong cold front with late Wednesday afternoon temperatures ranging from the 70s ahead of the front to the 60s behind the front.  Winds are gusty though from the southwest ahead of the front, and out of the northwest behind the front.

Goes-16 visible satellite loop from Wednesday, April 24, 2019.

Clouds and spotty showers this morning as a warm front moved through the area, some clearing for a time this afternoon, then as a cold front approached from the west, clouds and spotty rains redeveloped in parts of the Northland late in the afternoon.

A sloppy system on the way for Saturday, but the main impacts look to be south of the Northland. 

Low pressure is forecast to move east/southeast of the Western High Plains Friday night-Saturday with the surface low expected to pass south of Minnesota Saturday. 

Cold air north of the low will cause a rain-snow mix across much of southern Minnesota Saturday with some snow accumulation possible where heavier snow bands setup. 

Some light rain or snow could push as far north as the Brainerd and Hayward Lakes area Saturday, but again it looks like the heaviest precipitation would remain south of our area unless the track of the low shifts farther north.

Yes it’s late April and it will be difficult to get snow to accumulate during the day, but if the snow falls heavily enough and long enough, then some slushy snow accumulation is possible Saturday across portions of south-central Minnesota.

Weather Synopsis for Northeast Minnesota and Northwest Wisconsin

A warm late April day in the Northland with highs in the upper 60s to lower 70s with Brainerd climbing into the mid 70s! Highs today were around 15-20 degrees warmer than normal for April 24. 

The day started with clouds and a few rain showers/sprinkles thanks to a passing warm front, but skies became mostly sunny to partly sunny this afternoon with a few showers and isolated thunderstorms popping up late this afternoon near a cold front which was heading east/southeast out of north-central Minnesota. 

Winds were quite gusty today from the southwest at 10 to 20 mph with gusts 25 to around 40 mph in some spots this afternoon.

Note:  Duluth hit 70 degrees today for the 2nd time this month.  We’ve had 2 days with a high of at least 70 degrees this month which is right at the normal amount of 70 degree days (2) for the month of April.

Tonight:  Spotty showers and isolated thunderstorms will linger in parts of the area this evening with brief downpours, gusty winds and occasional lightning occurring in the strongest activity.  Mainly dry overnight under partly to mostly cloudy skies.  Lows tonight in mid 30s to mid 40s.

Thursday:  Breezy northwest winds 10 to 20 mph with higher gusts, otherwise a dry day ahead under mostly cloudy to mostly sunny skies.  One more mild day as well with highs in the 60s, possibly a few near 70 degree temperatures especially over southern portions of the Northland.  Another cold front will pass through the area later in the day and it’s behind this front where a chillier airmass will reside.  Cold air advection spreads into northeast Minnesota and northwest Wisconsin Thursday night with 850mb temperatures going from around +6C Thursday afternoon to around -2 to -8C Friday afternoon.

Friday:  Cooler temperatures although not too bad (yet) highs in the upper 40s to middle 50s which is near to slightly below normal for late April.

…Looking Ahead…

Although Saturday’s system looks like it will pass south of our area keeping us mainly dry, there are a few more systems showing up in model guidance that could impact parts of our area late this weekend into next week with possible rain or snow, but it should be noted that forecast models have been struggling big time as of late so it’s definitely a low confidence forecast after Friday.  One thing there is more agreement on are the temperatures which look to be cooler than normal this weekend through most of next week.

Forecast for Duluth

.Tonight…  Mostly cloudy to partly cloudy.  Isolated showers early.  Low 40 to 45.  Wind west to southwest 5 to 15 mph.

.Thursday…  Breezy.  Mostly cloudy to partly sunny.  High 63 to 68.  Wind northwest 10 to 20 mph with higher gusts possible.

.Friday…  Cooler.  Partly cloudy.  Breezy.  High 50 to 55.  Wind northwest 15 to 30 mph.
