KEY MESSAGES

- Showers with wetting rain impacts to outdoor activities should end west to east late afternoon into the evening.

- Winds gusting to 50 mph develop later this evening into the early morning hours Tuesday mainly towards the Devils Lake Basin and west of the Red River Valley.

..Winds Tonight

A cold front already starting to push east over wester ND will arrive later this evening and increased CAA 925MB will result in dry adiabatic mixed layer off the surface. While there may be a shallow nocturnal inversion, pressure rises and strong CAA at 925MB should help create at least a period of stronger winds from the west then northwest as the front passes. Winds near the top of the mixed layer may be near 50kt over parts of the Devils Lake Basin, and this raises the potential for a few localized gusts 58mph+, though more frequent gusts with the period of stronger winds would be 45-50mph. Due to the direction of the winds and orientation of unidirectional flow through the mixed layer being westerly it is less favorable for stronger gusts east of the Red River Valley escarpment, which matches higher resolution guidance in placement of advisory conditions mainly west of the valley in the 10pm-7am period. There is still potential for a few gusts 45-50 mph farther east or south than the current advisory, however location/duration/coverage are much less certain due to the previously mentioned flow/wind direction. It will be something to monitor in the event we have to expand the advisory based on trends this evening.

AVIATION /18Z TAFS THROUGH 18Z TUESDAY/

Issued at 1242 PM CDT Mon Sep 14 2026

Low pressure continues to bring areas of light to moderate showers to eastern ND and northwest MN, gusty southeast winds 30kt+, and a period of MVFR to IFR stratus on the back side of the main area of rain. Rain coverage should become more scattered in the afternoon in ND before ending west to east. There should be a period of improvement in the evening when showers end, VFR ceilings prevail, and winds decrease below 30kt, however a strong front arrives late evening into the morning hours bringing another period of gusty winds from the southwest to west to northwest, and MVFR stratus.

Most likely area for MVFR stratus later tonight/Tuesday morning would be in northeast ND and parts of northwest MN (VFR more likely to remain in place at KFAR tonight/Tuesday).
