.UPDATE...
Issued at 656 AM CDT Sun Oct 5 2025
A bit more dry air pushing into the central and northern RRV,
but additional showers and thunderstorms developing in the
southern Valley will push their way north. Eventually the entire
system will slowly move east and the cold front will push all
the way through. Made some minor adjustments to POPs but overall
forecast remains the same.

.DISCUSSION...
Issued at 343 AM CDT Sun Oct 5 2025
...Synopsis...
Main upper trough remains over the Northern Rockies, but water
vapor loop shows several lead shortwaves starting to swing into
the Dakotas this morning. Surface low pressure currently over
the James River Valley will lift northeastward into Ontario
today, and the cold front will push the rest of the way through
the CWA. Surface high pressure building in behind the front will
bring significantly colder air for the first part of the work
week, with much of the CWA getting into the 30s for lows. Brief
ridging building in Wednesday and again for the end of the week
will bring some above average temps back in for the later parts
of the forecast. However, signal for warmth is not nearly as
strong and highs look to be in the 70s instead of 90s.
...Rain today...
Fairly widespread rain across the Devils Lake Basin associated
with the mid-level deformation zone, which should move slowly
eastward through the morning before tapering off late this
afternoon. A few spots in Benson county have already seen more
than a half an inch of rain so far, with more expected.
Probabilities of getting above an inch are 80 to 90 percent
across much of northeastern ND, although chances of rain
amounts over 2 inches are less than 20 percent. With that, not
anticipating any issues other than annoyance from agricultural
interests and those with outdoor weekend plans.
...Wind advisory today...
HREF probabilities of gusts over 45 mph are very high in west
central MN early this morning in the southerly flow out ahead of
the low. However, in reality the gusts are more around 25 to 30
mph. The pressure gradient is expected to tighten as the surface
low deepens over the Red River Valley around 12Z. The north
winds on the backside of the system will be aided by cold air
advection and strong pressure rises, helping bring 45 kt low
level jet to the surface during the mid to late morning. HREF
probs for above 45 kts are above 60 percent in portions of the
northern Red River Valley. Some of the CAMs also show signs of a
sting jet, but not confident enough in this kind of feature to
go any higher than advisory. Winds across most of eastern ND
into the Red River Valley counties of MN will be at advisory
level at some point today. Elected to keep headlines simple for
a wind advisory and can cancel early if needed.
...Frost potential tonight into Wednesday morning...
The surface high building in quickly this evening will bring
decreasing clouds and winds to at least northwestern portions of
our CWA. Temps will drop down into the 30s, with chances of 36
or below above 50 percent for much of eastern ND into
northwestern MN tonight. Some high probabilities of below 32 up
in Towner county also. The chances for frost will continue into
tomorrow night as well as Tuesday night with the upper trough
continuing over the area and another reinforcing push of cooler
air expected Monday night.

.AVIATION /12Z TAFS THROUGH 12Z MONDAY/...
Issued at 656 AM CDT Sun Oct 5 2025
Ceilings range from VFR to IFR with dry air coming into central
portions of the forecast area under the center of the low. More
widespread rain around the KDVL area, and that band should push
eastward throughout the day. Conditions going down to MVFR to
IFR with winds shifting to the north or northwest behind the
boundary. Some wind gusts to 30 or 35 kts later today. The
precipitation and lower ceilings will move east of our forecast
area tonight, with most locations back to VFR by morning. Winds
will slowly diminish.
