Area Forecast Discussion National Weather Service Grand Forks ND 301 PM CDT Thu Sep 18 2025 .KEY MESSAGES... - Prolonged period of showers today through Saturday with a 70 percent or higher chance of 1 inch or more through Friday night. Best chance for these higher amounts will be in southeast North Dakota and the southern Red River Valley. && .DISCUSSION... Issued at 300 PM CDT Thu Sep 18 2025 ...Synopsis... Scattered showers continue to form this afternoon as an upper low moves very slowly to the northeast out of South Dakota. Movement of the low is inhibited by a narrow, but highly amplified, H5 ridge over the Great Lakes Region. The ridge is expected to continue moving east, albeit very slowly. As such, scattered showers are expected this afternoon through at least Friday evening, when the low will be centered over eastern North Dakota. During this time, a funnel or two will be possible; however, there is no expectation of strong or severe thunderstorms. Best chances for more persistent rain will be in southeast North Dakota this afternoon through Friday evening, but will shift into Minnesota heading into Saturday. Most of the shower activity will be east of the area on Sunday, with perhaps some lingering showers in northwest Minnesota. From Monday onward, ridging builds back into the Northern Plains, bringing dry weather and warm temperatures through much of next week. && .AVIATION /18Z TAFS THROUGH 18Z FRIDAY/... Issued at 1225 PM CDT Thu Sep 18 2025 MVFR to IFR conditions prevail at most sites this afternoon as an upper low continues to approach the area. Scattered showers and perhaps an isolated thunderstorm can be expected through much of the TAF period, with northeast winds at 10 to 15 knots. Heading into Friday morning, LIFR ceilings are possible as the upper low slowly moves closer to the area, bringing low stratus and BR. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...None.
