Frost Advisory issued for parts of the Northland. Scattered showers this evening, areas of frost overnight; mild/dry weather Monday-Wednesday; rain late this week (possibly some snow)

Frost Advisory issued for parts of north-central and northeast Minnesota from Midnight tonight to 9 AM Monday. Some cities included in the advisory are International Falls, Bigfork, Grand Rapids, Walker, Hill City, Moose Lake, Cloquet, Duluth, Hibbing, Cook, Orr and Ely. Temperatures as low as 35 degrees will result in frost formation. Frost could kill sensitive vegetation.

A strong area of low pressure continues to lift NE across Ontario and into Hudson Bay today, this is the same system which brought over an inch of rain to Duluth on Saturday.

The combination of daytime heating along with colder temperatures aloft led to the development of scattered showers across the Northland this afternoon, the showers should become less numerous after sunset.

High temperature forecast for Monday, October 7

Late this week/next weekend continues to look a little interesting with accumulating snow, rain and wind across the Northern Plains and upper Midwest.

1) Low pressure is forecast to be over the Central Plains Thursday morning. Low pressure is then forecast to lift north/northeast, but may start to slow down once it moves into southern Ontario.

2) The greatest chance for accumulating snow looks to be over parts of the Dakotas into northwest Minnesota (dark blue area on map) as this area will be firmly in the cold air late this week.

3) Rain may mix with or change to some snow farther east during the Friday to Saturday time frame (light blue area on map)

4) There continues to be some uncertainty on the storm track, and this could lead to some shifting of the snow and the rain to snow areas over the next few days.

Stay tuned

Precipitation totals of around 1 to 2 inches are possible late this week in most of the Northland. Source:

…Weather Summary…

Pleasant weather on the way the next few days.

Scattered showers will continue to move through parts of the Northland tonight, but the showers should become less numerous by late this evening.

Partly to mostly cloudy skies tonight with lows in the lower 30s to lower 40s with winds out of the west to southwest at 5 to 15 mph with gusts to 30 mph this evening.

A stretch of nice weather starts on Monday with mostly sunny to partly cloudy skies and no rain! Highs will range from the lower 50s to lower 60s with southwest winds 10 to 20 mph.

Tuesday should feature quite a bit of sunshine once again along with a breezy southerly wind with gusts to 25 mph. Highs on Tuesday will mainly be in the 60s.

Although Wednesday may feature an increase in clouds, temperatures still look to be on the mild side as south winds continue. Highs Wednesday will mainly be in the 60s once again although with S-SE winds, temperatures may be a tad cooler along the North Shore.

The weather will turn a little more active late this week as a strong upper level trough, cold front and area of low pressure affect the upper Midwest. Initially our area will be on the warm side of this system so precipitation will be in the form of rain from late Wednesday night into Thursday night, but colder air will eventually work its way into the Northland from SW-NE sometime Friday or Friday night, and this is when we could see the rain mix with or change to some snow. It continues to look like the greatest snow accumulations would remain west of the Northland late this week/next weekend, but the track of this system could change in coming days which may lead to some parts of the Northland getting some accumulating snow between October 11-13.

Much colder temperatures are forecast to move into the Northland late this week with highs by Saturday (12th) only in the 30s the way it looks now.
