.DISCUSSION...
Issued at 255 PM CST Sun Feb 22 2026

Currently, northwest flow aloft remains over the Northern
Plains with an upper level ridge building into the Rockies and
a broad upper level trough over the eastern CONUS. Surface high
pressure ridge extending across the central Dakotas this
afternoon, resulting in a clear sky and light winds across
western and central North Dakota. Temperatures outside of
southwest ND (where temperatures have risen into the teens
thanks to return flow) remain chilly in the single digits above
where a cold airmass remains.

Aforementioned ridge continues to build east across the Rockies
and into the Northern Plains for Monday, then broadens as it`s
flattened by multiple embedded waves and a strong upper level
jet Monday night into Tuesday. This pattern change coupled with
southerly flow/WAA ahead of a clipper system will bring a
milder airmass into the region, with temperatures warming by
20-30 degrees for Monday compared to today. Mid level wave and
upper level jet streak will push an associated sfc low and cold
front through the region Mon night, resulting in a swath of
light precipitation moving east-southeast over my northern and
eastern counties (mainly in the form of light snow). Most if not
all precipitation will be out of our area for Tuesday, with a
typical breezy and cooler post-frontal regime in the wake of the
cold FROPA.

A west-northwesterly flow pattern will then be in place for the
remainder of the week, keeping temperatures at or above normal
through Friday. Another S/WV and frontal passage occur Tue
night through Wednesday, bringing another decent chance for
precipitation to the Northern Plains. All snow is expected
outside of the southwest, where a rain/snow mix is forecast.
Amounts again look light (less than tenth of an inch), though
there is precip banding potential given models showing some Div
Q/mid level frontogensis linkage late Tue night/early Wed.

Afterwards, ensembles depict a broad troughing pattern over
Canada into the northern CONUS, suggesting temperatures trending
cooler for the weekend. Large spread in guidance regarding any
precipitation chances, as this will be dependent on smaller
scale features best resolved by models as we progress in time.

Patchy fog will be possible tonight over parts of central North
Dakota, but coverage will be low and still some question as to
whether it will develop. Otherwise, VFR conditions are expected.
