  see a dusting to near 1 inch.

  inches are possible in thin bands with amounts depending on
  duration and rate of snowfall.

.DISCUSSION...
Issued at 325 AM CST Sat Nov 8 2025

...Synopsis...

Shortwave currently over western ND will dive southeastward
today, arriving in the Iowa area by this evening. Cold air
advection will continue as surface high pressure builds in
behind the system. Another shortwave will dig down out of Canada
into the Upper Midwest tonight, turning flow aloft in a more
northerly direction. That will be short lived as upper ridging
starts building into the Rockies and western Plains on Monday,
with a trough developing to our northwest and southerly winds
picking up. Northwesterly flow aloft through the mid-week period
with some weak embedded shortwaves possible, although no
confidence to include any precip at this point. Temperatures
return to above average values, particularly on Friday as the
ridge axis starts to move east into our area.

...Light snow this morning...

Snow has been moving into our western counties, although radar
returns have been weakening in recent scans. New Rockford web
cam showed some decent snow rates for a while, with a few tenths
of an inch of accumulation. Still can`t rule out some of the
heavier mesoscale bands such as the one currently over Minot
radar moving into our area. However, most of the synoptic
forcing and good frontogenesis seems like it will be moving
southeast into SD in the next few hours. At least some snow
accumulation is likely for southeastern ND, but probabilities of
over 2 inches have dwindled down to nothing in that area. Could
see a dusting up to an inch before the system fully moves out of
the area.

...Lake effect snow near LoW this afternoon and evening...

One place that the HREF continues to show decent probabilities
for accumulating snow is downwind of Lake of the Woods. Chances
for more than 2 inches are around 40 percent and even 3 inches
and above is close to 20 percent. With continued cold air
advection over the relatively warm lake, lapse rates will be
rather high through today and even tomorrow. The main question
will be where exactly bands set up and how long they will last.
Still looking like anything from a dusting up to 4 inches is
possible over a very limited area, so will keep SPS going for
Lake of the Woods county.

.AVIATION /06Z TAFS THROUGH 06Z SUNDAY/...
Issued at 1116 PM CST Fri Nov 7 2025

Generally VFR conditions should prevail, although sites may
develop MVFR ceilings, especially at DVL and BJI. DVL is likely
to experience snow at some point within the first six hours of
the TAF period, potentially lingering into the morning. MVFR to
IFR visibilities are possible at times depending on the rate of
snowfall. Snow may extend as far east as GFK and FAR but
shouldn`t get much further than that.

Winds will increase through the late morning into the early
afternoon from the north. Given valley wind effects, it does
appear like 25-30 knots are possible, potentially higher.
Blowing snow shouldn`t be an issue after falling snow ends as
temperatures are fairly warm, but VFR obscurations of visibility
could arise if enough accumulations develop. Gusts will diminish
around 00z with sustained winds lingering above 10 knots
thereafter.
