.DISCUSSION...
Issued at 419 AM CDT Sat Apr 25 2026

Current surface analysis places low over southern Saskatchewan
with high nudging through the Northern Rockies. Upper level
analysis shows the Saskatchewan low being stacked, with its
influence over the northwestern and north central CONUS. Over
our area, most precipitation has ended, though a few light
flurries have been noted on some observations.

For today, westerly winds will continue over our area as the low
hangs out over southern Saskatchewan, becoming a bit gusty
over northern/western locations. With that said, we should
remain dry. Humidity values look to dip into the mid to upper
20s over a portion of central and western North Dakota.
Therefore, there will be an area of near critical fire weather
conditions where the higher winds and lower humidities overlap,
generally between I-94 and Highway 2, and east of Highway 85.
Quiet weather then expected Sunday night as persistant low
finally departs to the northeast. In the meantime, a swift
moving Pacific trough pushes over the Rockies.

On Sunday, surface low spins up and deepens over southeastern
Colorado into northeast New Mexico and pushes into the plains,
before lifting towards the upper Midwest on Monday. Models are
starting to come to a better agreement that precipitation will
occur over our area, but still some differences on the amounts.
Still, greatest amounts will be over our southeast, lesser
towards the northwest. Latest NBM is giving about a 50 to 80
percent chance of seeing a half inch or more of rain through
most of the James River Valley, and about a 40 to 70 percent
chance through south central ND. Over our northwest, chances for
precipitation are lower, but enough cold air is in place for any
precipitation to fall as snow. Colder air gradually works to
the east overnight Sunday night into Monday morning, with a
possible rain to wet snow transition throughout western and
north central North Dakota.

Behind this system we look to enter a mainly dry pattern through
the end of the work week. Temperatures look to hold below
average through mid-week, with a possible warm-up to end the
week going into the weekend.
