.UPDATE...
Issued at 137 AM CST Fri Feb 6 2026

No major updates early this morning, outside of adjusting sky
cover to reflect the southward increasing stratus this morning.
Will maintain a mention of light precipitation (flurries and/or
light showers) through the AM hours central and east in the wake
of a cold FROPA.

UPDATE
Issued at 957 PM CST Thu Feb 5 2026

Only some minor adjustments to sky cover late this evening.
Clouds dropping south from Canada have moved through Rolla,
Bottineau, Sherwood, Mohall and Rugby. Clouds should make it to
BowBells, Minot Harvey and Carrington in the next hour or so.
Otherwise, south and west of the Clouds, skies were clear.
Temperatures remain in the 30s to lower 40s. Updated text
products will be transmitted shortly.

UPDATE
Issued at 539 PM CST Thu Feb 5 2026

No changes to the going forecast this evening. Mostly clear
early this evening across western and central ND with
temperatures mainly in the 30s and 40s. We will some breezy
conditions as winds pick up. A cold front will drop into
northern portions of the forecast area late this evening
bringing clouds, cooler temperatures and possibly some scattered
flurries. Temperatures remain in the 30s to lower 40s. Updated
text products will be transmitted shortly.

.DISCUSSION...
Issued at 124 PM CST Thu Feb 5 2026

Well above average temperatures and dry conditions are expected
to prevail through the weekend as a well amplified west CONUS
ridge slides east over the central CONUS. Highs today have
already overperformed for parts of the area with widespread 40s
and some 50s present. That said, a cold frontal boundary off
surface low pressure over Ontario will slide from north to south
through the state tonight. This will bring low-level stratus
across most of the state, along with breezy to windy conditions
(windier south central and east) out of the northwest. A few
flurries may fall from this low-level stratus. With the latest
update, pockets of very light freezing drizzle in portions of
central ND are no longer advertised. However, there remains a
greater than zero chance it could still occur. Either way, as
supported by the HREF, accumulations on surfaces are not likely
at this time.

Behind the frontal boundary, seasonable temperatures are
expected in the far north central (mainly Turtle Mountains
vicinity) and east on Friday, with seasonably warm temperatures
elsewhere. This translates to highs in the teens far northeast
to the low 40s far southwest. There could also be a little
patchy fog mainly in the far southwest during the morning hours.
For Saturday, temperatures will begin to increase again with the
deterministic NBM highs currently from the upper teens northeast
to low 50s southwest. Of note, however, is a large NBM
25th/75th percentile temperature spread of around 10 degrees for
central and northwestern ND on Saturday, with a lower spread
east and southwest. This indicates some uncertainty on exactly
where the warmest airmass will set up, and potentially the
timing of a surface low sliding across south central Canada,
which will allow winds to switch to a warming westerly
component.

Despite the ridge likely beginning to break down around Saturday
night, models are in strong agreement that Sunday will be the
warmest day of the forecast overall as winds across the west and
central take on/maintain a westerly or southwesterly component,
while potentially remaining southerly in the east. NBM highs at
this time range from the 30s east and into the Turtle
Mountains, to the upper 50s or around 60 in the southwest. After
which, there are hints that a trough may dig into the western
CONUS early next week resulting in southwesterly flow aloft,
followed by the potential for the return of northwesterly flow
aloft. This could result in a more active pattern, which is
emphasized by the NBM producing fairly widespread 20 to 30
percent chances for light precipitation during much of the next
workweek, with the highest chances currently in the north Monday
night. While there remains some spread in the NBM ensemble,
temperatures during the middle and end of next week are overall
favored to become cooler than at the start of the week, albeit
still above average.

.AVIATION /06Z TAFS THROUGH 06Z SATURDAY/...
Issued at 957 PM CST Thu Feb 5 2026

A cold front will move through western and central North Dakota
tonight. Low clouds associated with the front are now pushing
south into the forecast area and will be through KMOT and KJMS
and approaching KXWA and KBIS by 06 UTC. MVFR and occasional
IFR Stratus is expected to push south and west to cover all of
western and central ND by mid morning Friday. Isolated flurries
are possible mainly directly behind the front, and lasting a few
hours, but confidence is too low to mention at any TAF sites
and impact are expected to be minimal. Will need to monitor for
patchy freezing drizzle as well. Confidence in FZDZ is just as
low or lower than flurries but so no mention in any TAF, but
impacts could be higher if FZDZ would materialize. CAMS have
been backing off on the signal for fog over western ND. Will
back off on the mention of fog at KDIK Friday morning. Northwest
winds 15 to 30 mph will diminish overnight and shift east to
southeast on Friday.
