Updated for the 18z Aviation Discussion below.
SHORT TERM. (Today through Saturday) Issued at 307 AM CST Fri Dec 6 2019
Temperatures trend colder today. Another clipper system moves through the Northland this afternoon and tonight and is expected to bring a round of light snow with accumulation generally up to 1 inch. Portions of Iron County, WI could see between 1 and 2 inches due to lake enhancement. Saturday trends warmer.
Northwest flow over the Northland this morning will usher in colder air for today. Temperatures for many locations have likely reached their highs for today. Temperatures will trend cooler through mid-morning and then rebound a bit for the afternoon. Daytime highs (excluding the readings during the pre-dawn hours) will reach the middle teens northeast to the low 20s in north- central Minnesota and portions of northwest Wisconsin. Another fast-moving clipper will pass over the Northland this afternoon and tonight. Forcing for ascent is weaker than Thursday’s clipper, and we expect lower snow totals. A swath of a dusting up to an inch of snow is expected over north-central Minnesota into the Arrowhead and portions of northwest Wisconsin. Areas in northern Ashland and Iron counties should see a little lake enhancement which will raise snow totals to between 1 and 2 inches. Winds turn westerly aloft which will usher in warmer air overnight and Saturday. Lows tonight will be in the upper single digits above zero to the middle teens. Highs on Saturday will reach the middle 20s to low 30s. Another weak clipper will cruise eastward across northern Ontario Saturday afternoon. There will be a slight chance of snow showers along the International Border as this system passes.
LONG TERM. (Saturday night through Thursday) Issued at 307 AM CST Fri Dec 6 2019
An upper level short wave pushes into western Minnesota Saturday night, with its associated surface low moving into northwest Ontario. Saturday evening should be fairly dry, except along the Borderland where the best forcing will be located from the approaching wave, and have some low pops. Due to the warm air already in place, a mix of freezing drizzle and snow is possible. As the surface low moves into Hudson Bay overnight, a cold front begins to move across the region. Model differences with the amount of QPF with this front, with the NAM way overdone, and has been ignored. Blending the GFS/GEM/ECMWF leads to chance pops along and east of Highway 53 in Minnesota and Wisconsin, with only minor amounts of QPF. Mixed precipitation types again ahead of the approaching cold front.
Sunday has the cold front moving through the area, with cold Arctic air behind it. Since the Arctic air is much drier, only have some low pops as it passes. Snow should be the main precipitation type. An upper level long wave trof follows behind Sunday night and signals the change to much below normal temps. Models are in better agreement then they were 24 hours ago. Have increased pops above the NBM Sunday night and Monday as it has pops that are unrepresentative as the trof moves into the western Great Lakes, and a surface low lifts northeast from the Central Plains Sunday night, into the eastern Great Lakes Monday. This adjustment led to higher QPF/Snow amounts as well. A general 1 to 3 inches will fall south of Minnesota 210, and south of US Highway 2 in Wisconsin. Some isolated higher amounts are possible.
The surface low continues off to the northeast Monday night. The cold Arctic air surges across the region as a closed upper low becomes established over Hudson Bay. This translates to a northwest surface flow, and lake effect snow will develop along the south shore of Lake Superior. Expect the snow showers to persist through Tuesday night, diminishing on Wednesday. Some accumulation will occur, but there are some differences amongst the models on exact wind direction, which affects the snow amounts. Much below normal temps, with overnight temps below zero Monday night, through Wednesday night. Wind chill values will be hazardous.
The aforementioned closed low begins to move east of Hudson Bay on Wednesday as high pressure drifts into the area. The flow aloft turns westerly on Thursday, with strong warm air advection, and the surface high drifts east. A fairly quiet weather pattern results.
AVIATION. (For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1148 AM CST Fri Dec 6 2019
Low MVFR/IFR stratus from earlier this morning has almost entirely dissipated late this morning, with only some higher-level cirrus clouds overhead and VFR conditions. There is some lingering low stratus west of KINL and KBRD, which may move over these TAF sites, but confidence isn't high enough to place in TAFs at this time. The main focus for tonight is on another clipper system that will move through the northern portions of our region this evening, quickly moving out before sunrise Saturday morning. This clipper should bring some light snow with it, which will mainly affect KINL, KHIB, and KDLH, with KBRD and KHYR mostly left untouched by the snow. KHIB could see accumulations of up to one inch this evening, with lesser amounts at KINL and KDLH. MVFR/IFR visibility reductions due to the snow are expected, with some MVFR/IFR ceilings as well, particularly after the clipper passes by as colder air aloft increases from the northwest. These low ceilings should continue through the Saturday morning hours.
MARINE. Issued at 307 AM CST Fri Dec 6 2019
A northwest wind of 10 to 15 knots this morning, will diminish in the afternoon before turning west. The wind becomes southwest tonight at 5 to 15 knots, and persists through Saturday night before turning west late. Waves will be less than 3 feet until Saturday night.

I do not sell or share any user data or anything else for that matter. I do not keep site logs longer than I need to to keep bad actors off the site. Basically, I delete them after looking at them.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
