Snowy, Windy Friday
The first snowstorm of the year Friday overachieved initial forecasts across portions of northern Minnesota, with a number of locations along the north shore and in the Arrowhead picking up over a half a foot of snow. Here were all the totals over 10" across northern Minnesota:
- 10.9" - Near Scanlon
- 10.6" - NWS Duluth
- 10.3" - Finland
- 10.1" - Holyoke
Looking at the snowfall analysis map, we can see that most of the heaviest snow fell across portions of northeastern Minnesota and into northern Wisconsin. Yellow indicated totals over 6", with orange indicating over 8" of snow.
The official total at Duluth was 10.6", making Friday the snowiest October day on record for the city.
So why did the storm produce more snow than expected? NWS Duluth meteorologist Carol Christenson gave an interview to the Duluth News Tribune answering that very question: "Christenson said forecasters knew there was going to be a lot of snow in the Arrowhead region with this storm, but the Duluth area got more than anticipated because of a lifting effect. Strong winds coming off of Lake Superior were forced upward — called orographic lifting — creating more snow and pushing it into higher elevations in areas such as Duluth Heights, Proctor, Hermantown and parts of Carlton County. Cold winds rolling over the relatively warm waters of Lake Superior probably contributed to more snow, along with rain changing to snow earlier than anticipated."
Snow totals were considerably less across southern Minnesota, with only a tenth of an inch accumulating at the Twin Cities airport.
Winds were also helping to blow that snow around, which decreased visibility Friday. Winds gusted over 30-40 mph across the state. The peak airport wind gust was recorded at the Duluth Sky Harbor airport, which gusted to 63 mph at 1:14 AM Friday.
These strong winds helped to whip up large waves on Lake Superior, which ended up doing damage along the lake shore in Duluth. Damage was reported along the lakewalk, at Brighton Beach and at Glensheen. Much more on the damage can be found from the Duluth News Tribune: "Sections of Lakewalk boardwalk were dislodged and tossed about by the waves, and much of the path was covered by rocks and other debris. The city closed the Lakewalk from Endion Station to and including the Portland Malt Shoppe stairway until further notice because of the damage, and there were barriers up because of additional damage near 16th Avenue East."
Light Rain Showers Today - Werewolf Watch Issued
By Paul Douglas
Here in the Land of Low Weather Expectations 32F feels considerably worse in October than it does in March. The first snow sparks irrational fear. It's the cold storms, snow falling at temperatures colder than 15F, that make me nervous - when chemicals can't effectively melt the snow and ice.
According to Sperling's Best Places, which analyzed natural disaster data, the Twin Cities is the 7th safest large metro area in the USA. Only cities like Salt Lake City and Portland are safer. We see a tornado from time to time, but nothing like the southern USA, where tornadoes, hurricanes & floods mean the highest risk cities are Oklahoma City and Austin to Miami. Feeling better? It was worth a shot.
The atmosphere should be just warm enough aloft for rain showers today. Flurries race past your window tomorrow, with a harsh breeze and 30s. Winds ease up a bit Halloween with some sun, but it will be chilly.
ECMWF (European) guidance shows the jet stream buckling, pumping mild air north by early next week. Before we're knee-deep in snow we will see more 50s, which will feel very good.

A frontal system will be passing through the state Sunday, bringing a chance of rain and snow with it to Minnesota during the morning hours, changing to rain by the afternoon. Highs will be in the 30s and 40s in most spots, though parts of southwest Minnesota could top 50.
Highs across the entire state Sunday will be below average for this time of year.
We'll see highs remain in the 30s and 40s for the next week here in the Twin Cities, with no real warm up possible until next weekend according to some of the models.
With a couple systems passing through the next few days, we will be watching the chance of accumulating precipitation. Accumulations are expected to be light across most of the state, with the heaviest occurring across far northern Minnesota.
We have several chances of precipitation with a number of systems passing over the region in the next week to week and a half here in the Twin Cities, with totals potentially topping a half of an inch.
With a couple snow chances in the forecast Sunday and again Monday, we could see some accumulation across mainly northern Minnesota. Both International Falls and Grand Marais could pick up over 2" of snow through Tuesday morning. Snow totals are expected to be minimal across central and southern Minnesota.
Take a look toward Halloween - it currently looks dry across the state of Minnesota. Highs are only expected to be in the 30s throughout the state (barely reaching freezing across northern Minnesota), so make sure you bundle those kids up as they head out trick-or-treating during the evening hours!
Highs in the wake of cold fronts pushing through the nation will be below average Sunday, in some areas by a good 15-20 degrees. Ahead of the cold front in New England, though, highs will still be above average.
Coastal Low This Weekend. A strong coastal low is expected to form along the East Coast this weekend as a cold front continues to move east. This system will tap into deep tropical moisture, allowing for the potential of heavy rain. Also, as the storm quickly strengthens and moves northward, damaging winds capable of tree damage and power outages can be expected Sunday Night into Monday across the Northeast.
Peak Wind Gusts Sunday. Winds will be on the increase during the day Sunday, with wind gusts in the 20 mph range from Caribou to Washington D.C. expected.
Peak Wind Gusts Sunday Night. Some of the highest wind gusts are expected Sunday Night into Monday across the Northeast as the system strengthens. Some areas of the Northeast could see wind gusts that approach 60 mph, with the strongest winds expected along the coast and in higher-terrain areas. These winds will be capable of tree damage and power outages, and cause delays at the major airports across the region.
Peak Wind Gusts Monday. Winds will continue to be strong due to this system across the region into Monday – especially during the first half of the day - with many areas continuing to see wind gusts in the 40 mph range.
Heavy Rain Concerns. This system will have deep tropical moisture available to it – some of which will come from Potential Tropical Cyclone 18 - that it will tap into starting Sunday and lasting into Monday. Widespread amounts of 2-4" can be expected, with isolated higher totals of 6" or more. This could lead to flash flooding across the region.
