637 AM CDT Fri Jun 13 2025
.KEY MESSAGES...
- Rain continues across southeastern North Dakota and west
central Minnesota this morning, with a 90 percent chance for
over a half an inch of rain south of I-94.
- Period of strong to severe storms next week in some locations.
&&
.UPDATE...
Issued at 636 AM CDT Fri Jun 13 2025
The frontal boundary across the ND/SD border finally moved and
shifted into west central Minnesota. Rain has overspread
southeastern ND and west central MN over the past couple of
hours and continues to move ENE. Rain will continue through the
mid morning as the upper level system shifts eastward.
Instability has weakened and thus the chances for thunderstorms
across the far southern forecast area. Still looking at chances
for isolated showers this afternoon/evening across northwestern
MN and into portions of southeastern ND.

.DISCUSSION...
Issued at 327 AM CDT Fri Jun 13 2025
...Synopsis...
Flow remains zonal aloft allowing for systems to ride along the
upper level ridge across central CONUS. These waves bring multiple
chances for showers and storms to the region over the course of the
next seven days. Currently an upper level wave is moving across
the Dakotas and Minnesota, with a baroclinic zone draped along
the ND/SD border. Rain and storms will continue through the
remainder of the morning hours, with isolated activity this
afternoon and drying conditions by this evening. Heavy rainfall
rates will be possible this morning for far southeastern ND and
into west central MN. Further systems work there way along the
zonal flow, with the next pushing through Saturday into Sunday.
A more robust system moves through late Sunday into Monday
bringing the chance for strong storms to the forecast area. As
we progress into next week we become active with multiple
chances of showers and storms, with a few being on the strong to
potential severe side. Temperatures through the weekend and
into next week will be around seasonal averages, with highs in
the 70s to lower 80s.
...Rainfall through the morning...
Current radar has an area of scattered showers and isolated storms
within Ransom, Sargent, Richland, and Wilkin counties. The
instability axis is draped along the baroclinic zone stretching
through northeastern SD. CAPE remains around 100-200 J/kg around the
ND/SD border and 500-700 J/kg within northeastern SD. The baroclinic
zone has been fairly stationary across northeastern SD this morning,
with strong warm air advection. Rainfall rates have been anywhere
from 1 to 2 inches within northeastern SD, with locally higher rates
as the thunderstorms have been training over the same locations.
CAMS keep the heaviest rainfall south of the forecast area this
morning. The instability axis and frontal boundary shifts ENE
through far southeastern ND into west central MN through the
morning. As the frontal boundary moves ENE showers and storms
will propagate into our forecast area.
Heavy rainfall rates and lightning will be possible with these
showers and storms as they progress into far southeastern ND and
through west central MN. Uncertainty arises in rainfall rates
for our area and the track of the showers and storms, with the
potential for a slight shift to the north (10 percent chance).
This would propagate the heavier rainfall rates and
thunderstorms from northeastern SD into Sargent, Ransom, and
Richland counties through west central MN. In turn, this would
increase rainfall rates up to an inch per hour as seen in areas
within northeastern SD. This scenario is unlikely as CAMS have
the heaviest precip remaining in northeastern SD this morning,
with the frontal boundary being fairly progressive as it shifts
through Minnesota limiting the potential for training storms.
High pressure toward the north is also helping to keep a sharp
gradient of moisture across the area, with dry air remaining
strongly in place across areas north of I-94. This will aid in
keeping the heavier rainfall south of our forecast area.
Probabilities of seeing over a half of an inch of rainfall is 90
percent for areas south of I-94 through the late morning hours.
Isolated showers and storms will be possible this afternoon
before conditions dry out as the upper level wave moves further
into Minnesota and through the Great Lakes.
...Active Period Next Week...
Several shortwaves move through the northern plains from this
weekend through next week. The first comes Saturday into Sunday
bringing the chance for showers and storms to the region. A more
robust system moves into the area late Sunday into Monday. This
system bares watching as latest guidance indicates a strong surge of
moisture and instability ahead of an approaching frontal boundary.
Looking at atmospheric soundings, profiles show shear ranging from
20-30kts, long skinny CAPE, and modest lapse rates. Storm mode looks
to start discrete in central and western ND and merge into a linear
segment as it progresses into eastern ND and northwestern MN.
Confidence is low at this time on development, track, and exact
storm mode but the system bares watching as our pattern becomes
active and machine learning indicates a 5 to 15 percent chance for
severe thunderstorms. Further chances for storms as we progress into
the new week, with the potential for stronger storms at times.

.AVIATION /12Z TAFS THROUGH 12Z SATURDAY/...
Issued at 636 AM CDT Fri Jun 13 2025
Isolated showers continue across portions of southeastern North
Dakota and parts of west central Minnesota this morning.
Chances affect FAR and BJI through the mid morning before the
showers and storms shift off toward the east. IFR to MVFR
conditions will continue for FAR through the morning and into
the afternoon and evening. The cloud deck with lower ceilings
will drift between GFK and FAR throughout the day and near the
end of the TAF period reach BJI, GFK, and TVF. Isolated showers
will be possible for FAR and BJI this afternoon and evening.
Otherwise, easterly winds throughout the TAF period, with gusts
reaching 25kts this morning and afternoon for each site but BJI.
