Marine Weather and Tide Forecast for Remer, MN

DISCUSSION
Issued at 157 AM CDT Thu Apr 16 2026

Dense fog continues this morning over and near Lake Superior. Much of this fog should start to burn off and retreat back to the coast through this morning. Southerly flow brings even more robust WAA today, with afternoon high temperatures expected to reach into the upper 60s to mid 70s for most of the area. This will lead to a drastic temperature differential with Lake Superior and a fog bank may linger over the lake through the day and could affect coastal areas at times.

Warm temperatures and good low level mixing is expected to lead to a very dry afternoon with minimum RH of 20-30% and breezy south winds with gusts of 20-30mph today. This will lead to some near critical fire weather conditions with a SPS out for areas in north-central and NE MN (not including the Arrowhead where conditions should stay more moist).

A low pressure system across the High Plains will track eastward on Friday as a longwave trough amplifies over the central CONUS. That will bring surge of warm and moist air across the Upper Midwest, while drier moves on top of it. This will set the stage for thunderstorms and potential severe storms Friday afternoon and evening ahead of an approaching cold front. This system has trended north just a tad, allowing a nose of instability and moisture further into the Northland. Timing is such that the cold front is expected to be around I-35 by midday, largely confining the severe threat to I-35 corridor and east with the highest threat (Slight risk, level 2/5) from Spooner to Hayward to Ironwood and southeast. Recent model soundings have trended to become more surface based in NW WI, increasing the threat of not only hail and damaging winds but tornadoes as well, especially for Sawyer and Price county. Any severe weather should be fairly progressive and move eastward quickly as the cold front moves into the UP. Thunderstorms could start to develop from 12-3pm and push east, with most guidance showing the best storm environment out of our area by 00z Saturday (7pm Friday). Any thunderstorms could be capable of producing some locally heavier rain up to 1". Flooding concerns are fairly minimal with the progressive nature of this system, but extra water will likely keep things wet in NW WI with high streamflows. Rain over melting snow on the North Shore will also keep streamflows high there but widespread flooding concerns are not expected at this time.

A decent blast of CAA follows this system with winds turning around to the NW Friday evening into Saturday. Guidance suggests that these NW winds could get fairly breezy and strong along the North Shore where gusts in excess of 30-40mph are possible. Much cooler conditions this weekend will result in a return to overnight lows below freezing and afternoon highs in the 30s and 40s. With the northward trend of the low pressure system Friday however, snow potential has decreased. Those along the border and in the MN Arrowhead might see a trace of accumulation with flurries elsewhere.
Ridging returns next week, bringing temperatures back into the 40s, 50s, and 60s in the afternoon. Most global guidance doesn't show our next widespread chance of precipitation until late next week into the weekend.

AVIATION /06Z TAFS THROUGH 06Z FRIDAY/
Issued at 1226 AM CDT Thu Apr 16 2026

Areas of fog are possible through this morning at all terminals except BRD. Most fog should reduce visibility to MVFR and high IFR levels, however 1/4SM fog is possible at DLH. Fog should burn off through this morning with a return to widespread VFR conditions.
South to southeast winds pick up through the day today with gusts of 15-20 knots possible. Some LLWS could start to build into the area by the end of the TAF period.

MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/
Issued at 157 AM CDT Thu Apr 16 2026

Breezy northeast winds are expected to develop through the day today, with some afternoon gusts up to 20 knots possible at the head of the lake. This period will need to be monitored for a possible marginal Small Craft Advisory. A fog bank is expected to still around over Lake Superior through the day today and the Marine Dense Fog Advisory has been extended through this evening. Into Friday, northeast winds continue through the morning, and then become northwest through the afternoon. Gusts of 20-30 knots are possible Friday and additional Small Craft Advisories may be needed. Stronger northwest winds with possible gale-force gusts are possible along the North Shore going into Saturday. Thunderstorms are expected Friday afternoon and early evening which may bring gusty and erratic winds, hail, and brief heavy downpours.

FIRE WEATHER
Issued at 157 AM CDT Thu Apr 16 2026

Much above normal temperatures enter the Northland today and Friday.
Warm temperatures (highs of 65-75F) and good low level mixing is expected to lead to a very dry afternoon with minimum RH of 20-30% and breezy south winds with gusts of 20-30mph. This will lead to some near critical fire weather conditions with a SPS out for areas in north-central and NE MN (not including the Arrowhead where conditions should stay more moist). A stout lake breeze boundary is likely to set up around Lake Superior. Winds pick up into Friday and temperatures stay warm, but an incoming system should improve moisture. Thunderstorms, some possible severe, are expected Friday midday through early evening. All hazards are possible in severe storms and some locally heavy rain is possible, most likely in NW WI. On the back side of that system, some very light snow may fall into Saturday.
