FXUS63 KFGF 220152 AFDFGF Area Forecast Discussion National Weather Service Grand Forks ND 852 PM CDT Sat Mar 21 2026 .KEY MESSAGES... - Light to moderate snow this evening into early overnight may bring travel impacts from brief drops in visibility under 1 mile and light slushy snow accumulations. - Temperatures will vary sharply from north to south for at least the next several days as a strong thermal boundary remains in place. && .UPDATE... Issued at 847 PM CDT Sat Mar 21 2026 700MB frontogenesis has helped organized a band of light to moderate snow over northeast ND and far northwest MN (along the Highway 2 corridor) which is progressing southeast. Webcams and surface reports show brief visibility reductions below mile (most locations 1-3 miles) and some indications on webcams of light slushy accumulations. This is progressing quickly and drier mid levels/limited moisture advection will limit duration of any higher rates that may be occuring as this moves across our region. Short range CAMs generally show this disorganizing/weakening as it moves across the southern RRV after midnight, though so far they haven't done a great job until current runs on reflecting current coverage/organization. && .DISCUSSION... Issued at 309 PM CDT Sat Mar 21 2026 ...Synopsis... Cooler air works into the area tonight following a brief period of light rain/snow mix. North to northwest winds prevail into Sunday, then shift to the south on Monday. A strong baroclinic zone is expected to remain in place across the northern CONUS, with much colder air to the north and warm air to the south. As such, temperatures will vary greatly from north to south. Look for a rebound into the 50s for areas in southeast North Dakota, with highs in the upper 30s to low 40s in northwest Minnesota on Monday. Tuesday brings similar temps, with a slightly warmer day on Wednesday. Another cold front brings a chance for precipitation Wednesday into Thursday; however, confidence remains somewhat low as ensemble guidance has higher than average disagreement, as well as several potential scenarios. Heading into Friday and the weekend, additional uncertainty surrounds another potential trough passage and cold front. && .AVIATION /00Z TAFS THROUGH 00Z MONDAY/... Issued at 631 PM CDT Sat Mar 21 2026 IFR ceilings have moved across eastern ND and northwest MN behind a cold front, along with gusty northerly winds. The main area of IFR ceilings is beginning to transition south early in the TAF period, with MVFR ceilings returning and prevailing through Sunday morning across eastern ND and through the end of the TAF period across northwest MN. Rain and snow showers are progressing into the region north of Highway 2 behind the cold front and will eventually transition south through the evening hours. Much of this activity is virga or very light, but there are reports over northwest ND of brief visibilities dropping with moderate showers and this can't be ruled out this evening as this activity passes (though location/duration of impacts are more uncertain). && .FGF WATCHES/WARNINGS/ADVISORIES...
