Area Forecast Discussion National Weather Service Duluth MN 303 PM CDT Fri Oct 23 2026
KEY MESSAGES
- Fog will linger near and over Lake Superior for the rest of the afternoon and into the evening.
- Rain showers are expected tonight and again Saturday daytime as a couple fronts move through the Northland. Accumulations will be less than 0.25".
- Cooler temperatures and more chances for rain and a few flakes of snow will follow early to mid week.
DISCUSSION
Issued at 217 PM CDT Fri Oct 23 2026
Fog lingers in areas near Lake Superior this afternoon. Dense This fog is expected to clear as a warm front makes its way northeast. Temperatures for the rest of the day will push into the upper 60s and 70s inland, though the shoreline will stay slightly cooler under the fog and cloud cover. A warm front will move through today, shifting winds to the south to southwest and increasing gusts to up to 30 mph tonight. Rain showers will also follow the warm front in the late afternoon and overnight hours. Most will see rain accumulations of less then 0.1".
Saturday, the associated low pressure system tracking east will also bring a cold front west to east across our area. This boundary will provide another round of light rain showers and perhaps an isolated rumble of thunder. Strong southerly flow continues ahead of the front will allow highs to climb into the 60s and lower 70s once again, marking our last warm day for the foreseeable future. Rain chances will quickly taper off from west to east Saturday night.
A much cooler and more seasonable air mass settles in on Sunday behind the departing cold front. Highs will only reach the 40s and 50s under mostly sunny skies as surface high pressure builds in over the area. RHs dip back down into the 25-35% range Sunday, but with lower winds, no fire weather concerns are anticipated.
The cooler air mass will allow Sunday night temperatures to drop below freezing for most inland locations.
The extended forecast for Monday through Thursday features a return to an active weather pattern. An upper level low is forecast to move east out of the central Rockies early next week, bringing widespread precipitation chances to the region from Monday into Wednesday. With the cooler air mass firmly in place, some snow could mix in on the northern fringes of the system, though this is currently expected to be minor conversational snow with small accumulations, if any. High temperatures will largely remain in the 40s and 50s through Thursday with overnight lows near or below freezing.
AVIATION /18Z TAFS THROUGH 18Z SATURDAY/
Issued at 1220 PM CDT Fri Oct 23 2026
Fog is slowly lifting at DLH, and is expected to continue rising over the next hour to hour and a half. Fog should remain away from the terminal as a warm front makes its way northeast over the Twin Ports. While VFR conditions prevail for all terminals, an occasional heavier shower could lead to MVFR visibilities.
Then, strong winds aloft along and behind the showers will lead to LLWS for tonight and into tomorrow morning. Chances for rain return near the end of the TAF period, but not confident enough in any reductions to include in this round of TAFs.
MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/
Issued at 217 PM CDT Fri Oct 23 2026
Fog lingers in areas near Lake Superior this afternoon. Dense Fog Advisories have been extended for the near shore waters along most of the South Shore into the Twin Ports this evening, and into tonight for the North Shore. This fog is expected to clear as a warm front makes its way northeast with light rain showers. Northeast winds around 5 to 10 knots this afternoon will flip to the south and increase tonight into Saturday. Wind gusts to 25 knots and building waves will likely require a Small Craft Advisory by early morning Saturday.
For the open water discussion, refer to the NWS Marquette Area Forecast Discussion at weather.gov/mqt.
FIRE WEATHER
Issued at 217 PM CDT Fri Oct 23 2026
Rain showers will follow a warm front lifting northeast today, bringing light rain showers this afternoon and tonight. Gusty winds up to 30 mph will also continue overnight. Additional rain arrives on Saturday as a cold front crosses the area, and winds will decrease as winds shift from the south/southwest to the northwest. RHs dip back down into the 25-35% range Sunday, but with lower winds there is no fire weather concerns. Cooler conditions will persist through next week.
See the Fire Weather Forecast product for a more thorough breakdown of fire weather conditions.
