An active weather pattern continues in the Northland.
Gusty winds tonight into Thursday morning, with another round of gusty winds possible Friday.
A few rain and snow showers tonight and Thursday followed by a potential for a minor snow event which may hit parts of the Northland Thursday night/Friday, but the bigger story may be a system which could impact at least parts of the Northland this weekend with a chance for several inches of snow in the late Saturday to Sunday time frame. A few more systems are in the pipeline for next week, but storm tracks and precip/snow amounts TBD… That double dip La Nina has arrived!
Gusty west to northwest winds is expected to develop over the Northland this evening, with windy conditions continuing overnight into Thursday morning. The strongest winds are expected to occur late tonight into early Thursday morning when wind gusts could reach 30 to 50 mph especially along the North Shore of Lake Superior where a wind advisory is in effect from 9 PM this evening to 6 AM Thursday including the cities of Grand Marais, Silver Bay, Two Harbors and Duluth.
A rough night to be on Lake Superior!
Gale to Storm Force winds is forecast to develop over Lake Superior later tonight into Thursday morning.
Winds will be out of the west which will cause the largest waves (possibly >10 feet) to occur over central/eastern portions of Lake Superior.
Widespread wind gusts of 15 to 30 mph in the Northland tonight into Thursday morning with wind gusts to 50 mph along the North Shore of Lake Superior. Winds will diminish Thursday afternoon.
Wind gust forecast ending Noon Thursday.

Here’s what we’re looking at for this weekend
Low pressure is forecast to move out of the Northern Rockies or Western High Plains region, but the track of this low and how quick it moves through will play a role on how much snow will see in the Northland this weekend.
A more northerly track to the low would keep the greatest snow amounts north of Duluth, favoring far northern Minnesota and Arrowhead regions, but a more southerly track to the low would likely bring the greater snow amounts further south into the Twin Ports. At the moment it looks like we could see snowfall amounts of 4″ or more wherever that main snow band sets up.
The trend over the last day or so is for this low to shift more to the north, but whether or not that trend continues in the computer models remains to be seen.
A powerful jet stream is separating arctic air to the northwest and warm air to the southwest.
Winds at 250mb (~33,000 feet) are howling at speeds of 140 to 180 knots from western Canada to the upper Midwest late this afternoon.
Wind speeds at 250mb are running 1 to 3 sigma from western Canada to the upper Midwest late today, so a little unusual to have such a strong jet stream over these areas in early December.
6 PM on December 1st and we have temperatures which are still in the 50s over southern Minnesota, and in the 60s in South Dakota, with 40s in northern Minnesota.
Ridiculously warm for this time of day in the Northern Rockies and Northern Plains.
