794 FXUS63 KDLH 290720 AFDDLH Area Forecast Discussion National Weather Service Duluth MN 220 AM CDT Tue Sep 29 2026 .KEY MESSAGES... - Widespread rainfall today ends early tonight. - Warm temperatures through Wednesday, then cooling down Thursday and into the weekend. - Frost and freezing low temperatures are expected starting Thursday night and lasting into the weekend. && .DISCUSSION... Issued at 217 AM CDT Tue Sep 29 2026 Early this morning, radar and satellite imagery shows the ongoing band of moderate to pockets of heavy rainfall over the Red River Valley terminating into far north-cental Minnesota. This band will slowly move eastward over the rest of the Northland later today and bring a tenth to a half-inch of rain. Once this band exits inland northwest Wisconsin early tonight, the trends for rainfall on Wednesday rainfall have trended downward notably over the last 24 hours. What was once looking like two different rounds of rainfall for northwest Wisconsin is now more of just a round one event through this evening. Tonight, fog may develop across much of the region and we will monitor for any Dense Fog Advisory needs if it looks to be trending more dense over the next few forecast updates. The fog tonight into Wednesday clears later Wednesday morning as daytime temperatures quickly spike and peak in the low to mid-70s, and a few spots in northwest Wisconsin may peak into the upper-70s. Any lingering precipitation will be limited to spotty and light rain showers for inland northwest Wisconsin. This warmth quickly passes though with a cold frontal passage early Thursday morning. A cool down of 10 to 15 degrees will occur on Thursday compared to Wednesday, but temperatures will still remain fairly seasonable given the very warm day Wednesday. Expect breezy conditions Thursday as winds gust 20 to 30 mph. A generally drier airmass sets up behind the front, so dewpoints will be much lower into the rest of the forecast period, dropping into the 30s and 40s versus the 50s and low-60s observed recently. We will expect much lower relative humidity each day from Thursday onward. High pressure will dominate the late week and early next week weather pattern. From Thursday night onward, there is potential each night for frost somewhere in the region. Minimum temperatures for Thursday night into early Friday morning have trended downward, and frost or freeze headlines are very likely Thursday night and maybe each night into the weekend for at least some parts of the area. Friday night a Northern U.S. Rockies shortwave trough with Pacific moisture deepens along the MT/ND/MB border area and helps to create scattered light rain showers for Saturday daytime as it passes through the Upper Midwest. Following this quick system, a generally minimal to no precipitation pattern is forecast into early next week. && .AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/... Issued at 1224 AM CDT Tue Sep 29 2026 MVFR ceilings have lowered across the Minnesota terminals except BRD. These MVFR ceilings will continue to make their way east throughout the rest of tonight and into Tuesday morning. Opted to trend ceilings and visibilities a little higher than previous TAFs and latest model guidance since they seem to be overdoing the lowering from these rain showers and occasional storm. However, IFR ceilings are still possible late tomorrow evening, though we will have to see if that trend continues. && .MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/... Issued at 218 AM CDT Tue Sep 29 2026 A Small Craft Advisory remains in effect from late this morning through this evening from Grand Portage to Grand Marais due to gusty southerly winds up to 25 knots and building waves. Rain showers will move across western Lake Superior today. By Wednesday night and into Thursday, a cold front will sweep across the lake, shifting winds to the west and increasing gusts up to 30 knots along the North Shore, which may need additional Small Craft Advisories. For the open water discussion, refer to the NWS Marquette Area Forecast Discussion at weather.gov/mqt. && .FIRE WEATHER... Issued at 221 AM CDT Tue Sep 29 2026 A band of rainfall will bring a tenth to a half-inch of wetting rain to the region today. Minimum relative humidity will remain high today and Wednesday, generally above 50 percent. Southerly winds around 10 to 15 mph are expected today. A cold front passes late Wednesday night into early Thursday, shifting winds to the northwest with gusts of 20 to 30 mph. A drier airmass will drop dewpoints into the 30s and 40s, leading to much lower relative humidity from Thursday onward. This setup for late this weekend onward begins to look more like the beginning of a pattern shift favoring the fall fire weather season looking into early October.
