FXUS63 KFGF 221343 AFDFGF Area Forecast Discussion National Weather Service Grand Forks ND 843 AM CDT Sun Mar 22 2026 .KEY MESSAGES... - Temperatures will vary sharply from north to south for the next several days as a strong thermal boundary remains in place. && UPDATE Issued at 621 AM CDT Sun Mar 22 2026 Update for 12z TAF aviation discussion. No change to messaging has been needed. && .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 /12Z TAFS THROUGH 12Z MONDAY/... Issued at 621 AM CDT Sun Mar 22 2026 Expect some holes of clearing as we go through the day, but more widespread clearing this evening.
