A weak band of light rain will slide east with a chance for the season's first light snow across the Devils Lake basin into Friday morning, then a brief warm, gusty Sunday brings mid-50s to low-60s. Minimal impacts but wet trails and gusty winds mean adapt your plans.

This forecast discussion covers the broader NWS Grand Forks service area — northeast North Dakota and northwest Minnesota, including the Red River Valley, Devils Lake basin, lake country in NW Minnesota, Thief River Falls, Grand Forks and Jamestown corridors — not just the Grand Forks city limits.

A compact sequence of weather features will guide outdoor conditions this week across northeast North Dakota and northwest Minnesota. The immediate story is a band of very light precipitation that has worked into Minnesota this morning and will very gradually creep eastward. That light rain is riding ahead of a shortwave and a surface trough/warm front anchored to a deeper 500 mb low dropping out of central Saskatchewan. Sky-cover trends and a front passage will be the small but crucial details that change what you see on the trail.
Today: Expect mostly cloudy skies with a late-morning brightening in parts of the Red River Valley and eastern North Dakota. The rain shield is weak — radar looks brighter than what reaches the ground because the lowest few thousand feet of the atmosphere are dry. So far accumulations are tiny (traces to a few hundredths of an inch) and impacts will be negligible. Winds from the WSW at roughly 10–15 mph will make it feel a little brisk on exposed ridgelines and lakeshores.
Tonight into Friday morning: As the upper low approaches and a cold front surges in from the north, low stratus will fill in and high-resolution ensembles (HREF, REFS) have nudged up the probability of seeing snow in portions of the western side of the forecast area. There’s roughly a 60% chance for measurable snow (light, mostly dustings) west of the Red River Valley — places like the Devils Lake basin, James and Sheyenne River valleys — with the most likely impacts being light crusting on grass, vehicles, and other cold surfaces. Elsewhere the chance drops to near 20% and any flakes would be fleeting. Ground temperatures remain warm enough that even where flakes fall, accumulations on roads are unlikely. Overnight ceilings will lower — aviation briefings point to falling MVFR/IFR ceilings late tonight as the upper low drifts southeast.
Friday day into Friday night: The stacked low moves southeast through central ND. Precipitation amounts remain very light — most spots should see under 0.05 inches of liquid equivalent — with a brief mixing window where rain briefly flips to light snow in the coldest pockets. Gusty northwest winds develop across eastern ND tonight into Friday, which will sap temperatures and make for chilly, raw conditions for any exposed outdoor plans.
Weekend and next week: A short-lived ridge builds behind the departing low. Saturday will be calmer and partly sunny. Sunday, however, brings the warmest temperatures of the week with gusty WSW winds and highs climbing into the mid 50s — low 60s are possible in some southern parts of the area. That warm, breezy pattern lingers into early next week: models keep temperatures about 10–15°F above normal Monday through Wednesday as a strong north Pacific jet races along the Canada–US border, steering quick-moving systems to our north and keeping our area mainly dry.
What this means for outdoor adventurers: The immediate window (today into Friday morning) calls for flexible, low-impact plans. Expect damp trails, slick leaves and roots, and the chance of a light dusting of snow on grassy and elevated surfaces — enough to be photogenic and to make you reach for waterproof footwear, but not enough to force cancellations. Friday’s northwest gusts mean exposed ridge running, windsurfing on smaller lakes, or open-water paddling will feel tougher and chillier; secure any gear. The payoff arrives Sunday — an energetic, warmer day suited to longer rides, wind-borne lake sports, and trail maintenance or longer day hikes — but watch the gusts and loosened limbs over trails.
Small details to file away: 1) Radar overstates precipitation at times due to a dry sub-cloud layer — so drizzle shown on radar may not reach the forest floor. 2) Early-season snow under light rates most likely clings to grass and vehicles before roads — don’t be lulled into thinking cold pavement means more icing elsewhere. 3) Aviation and visibility notes: ceilings lowering to MVFR/IFR overnight could make sunrise or late-afternoon flights, remote paddles, or long alpine-style approaches more challenging.
Bottom line: Minimal impacts but stay weather-aware as small transitions (cloud cover, a few flurries, or a gusty wind shift) can alter comfort and safety for outdoor plans. Pack layers, waterproof footwear, and a windshell for Friday and Sunday’s gusty windows. If you’re chasing scenery, that first dusting of snow in low spots and across grassy benches will be worth the camera — especially during the clearing and warm-up Sunday brings.
Mostly light precipitation and very limited accumulations keep most activities viable; chilly NW winds Friday and gusty WSW winds Sunday alter the suitability for exposed activities. Overall favorable for day hikes, gravel rides, and lake-side adventures with adjustments.
Hiking, trail running, and gravel biking score high today–Saturday (wet trail caution).
Paddling and sailing are lower-confidence Friday (northwest gusts) but high potential Sunday with strong WSW winds for wind-based lake sports.
First-snow photographers get great opportunities in the Devils Lake basin and NW MN lake country where light dustings are most likely.
A 500 mb low over central Saskatchewan ejects a short wave and surface trough southeast into central ND. Light rain ahead of the front will gradually move east; cold-air advection behind the front yields a chance of light snow late tonight into Friday morning. A brief ridge builds this weekend with a warm, gusty Sunday. A northern Pacific jet keeps subsequent systems north, allowing above-normal temperatures early next week.
500 mb low centered over central Saskatchewan
Short wave trough and surface trough/warm front progressing east through central ND
Cold advection behind the front producing low stratus and minor snow chances
Transient upper ridge this weekend allowing a warm WSW surge Sunday
Fast 300–500 mb jet along the Canada–US border steering systems to the north next week

Cloud breaks this morning and limited rain mean trails are passable; light precipitation is expected to remain light and mainly eastward.
Late morning to early afternoon today (Thu), or Saturday morning
Expect damp leaves and slick roots; bring traction-conscious footwear.
Ensembles show the highest chance of light snow west of the Red River Valley tonight into Friday morning, enough for photogenic dustings on grass and low vegetation.
Late tonight into Friday morning for fresh flakes; clearings may appear Friday afternoon
Roads likely unaffected but chilly starts and slick deck/vehicle surfaces possible—carry microspikes if hiking at dawn.
Sunday brings the warmest air and strong WSW winds — ideal for kiting and windsurfing on larger lakes if you can handle gusts.
Sunday midday–afternoon
Gusts up to ~35 mph possible; wear a buoyant wetsuit or drysuit, scout for submerged hazards, and launch from protected points if possible.
Even light rain or flurries makes leaf-covered trails and exposed roots slippery. Shorten your stride on descents and use trekking poles if unsure.
Sunday’s warm day comes with strong WSW gusts. A breathable windshell and a secure hat will keep comfort high while allowing activity.
Where grass temperatures drop below freezing, light accumulation on grassy benches or vehicles is possible. Microspikes help on icy boardwalks and bridges.
Strong gusts and shifting winds can deposit debris and change shallow water entry points; inspect launch sites carefully on high-wind days.
Grip and protection on wet, leaf-covered trails and early frosts.
Useful for gusty Friday nights and particularly on Sunday’s windy warm surge.
Helpful at dawn when light rime or frost is present on flat grassy surfaces and bridges.
Protects electronics and layers during light rain or drizzle.
