18z RGEM model 10-30-2018
Note: The first storm on Halloween won’t affect the Northland as it stays well to our south, tracking from west Texas to the Ohio Valley, but the next two systems could impact parts of the Northland this weekend thru the middle of next week depending on the storm tracks.
Note: An area of low pressure is forecast to move S/SE out of the northern Plains later this week, this system looks like it will remain far enough west/south of the Northland to give us any precipitation Thursday night and Friday, but some light lake effect rain or snow could develop near Lake Superior Thursday night or Friday as winds turn to the east.
Greatest precipitation totals thru the weekend are forecast to be over northwest U.S.; and from the southern to eastern U.S.

Weather Synopsis for northeast Minnesota and northwest Wisconsin
We had the round of rain this morning, then skies cleared a bit over parts of the area this afternoon with quite a bit of sunshine late this afternoon roughly west/south of a line from Bigfork to Cloquet with more clouds north and east. Highs today were in the 40s to around 50 degrees which is near to a few degrees warmer than normal on this 2nd to last day of October 2018.
Surface map late this afternoon had an area of low pressure along the Manitoba-Ontario province line with a cold front stretching from central Lake Superior to western Illinois.
A secondary cold front will swing SE through the Northland tonight and should exit to the S/E by Wednesday afternoon. Partly to mostly cloudy skies are expected across the area tonight and Wednesday with a few spotty light rain or snow showers possible.
Lows tonight will mainly be in the 30s with highs on Halloween in the upper 30s to lower 40s which is a few degrees below average.
Thursday looks mainly dry at the moment with highs in the 30s to around 40 degrees.
System for Thursday night and Friday looks to remain west/south of our area per model guidance, so most of the attention is with the next system for this weekend, and this one could have more of an impact on our weather as low pressure heads SE out of western Canada. This system if it tracks far enough north could bring some rain or snow to northeast Minnesota and northwest Wisconsin from Saturday afternoon through Sunday with a couple inches of snow accumulation possible over some parts of the area. Note: The 12z European model from Tuesday is very aggressive in terms of snowfall potential with several inches (Possibly 4″+) accumulations over much of the Northland for late this weekend. Certainly something to monitor over the next few days.
