UPDATE

Issued at 638 AM CDT Fri Apr 24 2026

Cloud cover wrapping around upper low is now pushing its way into northwest North Dakota, though precipitation is still holding off to the west. Expect this to continue spreading into the area this morning.

DISCUSSION

Issued at 349 AM CDT Fri Apr 24 2026

Current surface analysis places broad low over west-central Manitoba. Upper level analysis places low over southern Saskatchewan. Broad area of rain/snow over western South Dakota has been trying to spread into south central North Dakota but so far has been failing, while some shower activity has been developing over northeast Montana.

For today, persist upper low remains over southeastern Saskatchewan, wavering towards and away from the international border, while surface low starts retracting towards the west. Low to medium precipitation chances wrap around the low into our area through the day. Over the northwest, expect any shower activity to be snow, with mainly rain for remaining locations. Where snow showers do occur, latest RAP continues to show pockets of instability (~200-400 J/Kg), so cant rule out occasional very brief periods of moderate to heavy snow showers. Westerly winds will be on the increase, strongest over the northwest. With that said, overall winds will be lower than yesterday and should stay below advisory criteria, but can't rule out an occasional higher gust, especially in the vicinity of any shower.

Upper low does a gradual northward lift for Saturday, keeping a westerly breeze over our area.

By Sunday upper low shifts further north over Saskatchewan and Manitoba, with southwest flow over our area. A notable wave passes over the Rockies and deepens as it pushes into the plains with a surface low spinning up. This will result in a broad area of precipitation developing but question still exists on how far to the northwest this precipitation will extend into our area. Clusters still split on strength of this system, but chances are looking higher that at least the southern/eastern portions of our area will see precipitation Sunday into Monday.

Behind this system guidance suggests we enter a quieter and drier period for the middle and later portions of the upcoming work week though temperatures still remain somewhat on the cooler side.

Issued at 638 AM CDT Fri Apr 24 2026

Scattered rain and snow showers are expected to develop over western and central North Dakota today. Over northwest North Dakota, expect mainly snow, which could cause brief visibility reductions to IFR and possibly LIFR levels in heavier snow showers. Elsewhere, mainly rain is expected with possible visibility restrictions to MVFR levels. Precipitation dissipates this evening. Westerly winds will again be on the increase with the gustiest winds over northwest North Dakota.
