12z European model (ECMWF) 12-13-18
Temperature anomaly forecast in 6 hour increments valid from 6 AM Friday, December 14 to 6 AM Saturday, December 23, 2018.
Anytime you see dark red and gray colors on this map you know you’re dealing with temperatures that are running well above normal! Looks very mild around here thru most of next week, but some changes begin to take place as we head into next weekend with temperatures cooling off some, at least closer to normal the way it looks now.

Took until late this afternoon, but the clearing line finally reached the Twin Ports just in time for sunset, fail! Skies cleared earlier in the afternoon across western and north-central Minnesota.

12z European Ensemble model (EPS) 12-13-18
For those wanting some snow you’ll have to wait a little longer, but long range model trends continue to support a little snowier pattern setting up for later this month (Dec 19 and beyond) but as always it’ll come down to the storm track which will determine if we get some snow or get missed here in the Northland.
Weather Synopsis for Northeast Minnesota and Northwest Wisconsin
A weak system moved through the region today bringing some light snow and drizzle to parts of the area with snowfall accumulations of a trace to just under an inch. Mostly cloudy skies to start the day but some drier air on west winds behind a surface trough led to clearing skies from west to east this afternoon. Highs today were mainly in the 30s.
The big weather story around here through Saturday will be the sky condition, yes I know very exciting for weather nerds. Low sun angle at this time of year, combined with snow melt and a temperature inversion with warmer temps aloft, cooler air near the surface could lead to the development of low clouds and some fog at night, and these conditions could persist into the daytime hours of Friday and Saturday. Computer models disagree on sky conditions with the HRRR and EURO showing mainly sunny skies on Friday while the NAM is going the other direction keeping us socked in with low level cloudiness through the day. Tough to say which model camp is right as either scenario could play out. One thing we have going for us on Friday is a stronger low level jet of 25-45 knots out of the NW which could mix up the atmosphere enough to give us ample amounts of sun.
As for the temperatures — Lows tonight will be in the teens and 20s with single digits possible in the typical cold spots. Highs Friday, Saturday and Sunday will range from the mid 30s to mid 40s.
Note: The weather pattern could turn a little more active (Snowier) around here around or after December 19, although it doesn’t look like we would be hit with any major amount of snow based on model trends, but could certainly see a few snow events affect parts of the Northland later this month.
