.DISCUSSION...

...Synopsis...
Now that that storm system in Manitoba has moved well northeast,
500 mb flow has become southwest over the area with widespread
mid and high level moisture spreading northeast into the
foreccast area this morning. Clear enough sky the first part of
he night to see temps drop into the mid 20s in far northeast ND
and northwest MN, but temps have stabilized since 07z. Expect a
mostly cloudy sky or becoming mostly cloudy sky today and clouds
to hold thru end of the week. Now position of the 500 mb upper
ridge over central and east Texas is keeping any deeper moisture
from advecting north, and also water vapor shows limited
moisture from the Pacific into northwest Mexico. So despite
several upper waves moving thru the next few days, rainfall will
not be as heavy as it could be.
One broad short wave and mid level jet moving from eastern
Wyoming thru northwest SD into North Dakota today, with
addition short wave energy moving western Nebraska across
central South Dakota into Minnesota this afternoon. It looks
like two areas where showers are more likely one in southwest
into parts of central ND and the other focused in eastern SD
into southern and parts of central MN. Sfc high center and dry
air over southern Manitoba into northeast ND and northern MN
this morning. Soundings from GFS and NAM for GFK and DVL show
dry air hanging on til 17z DVL and 20z GFK and hanging on all
day in BDE. So this will limit rain chances in NW MN and far
north RRV. Used a blend of NBM/Conshort/ECAM to blend with
neighboring offices and tweeked toward a drier scenario for NW
MN. Rain amounts look quite light for our area today into this
evening, under a tenth.
Strong 500 mb low dropping south along the central California
coast early this morning will move inland into Nevada and Utah
late Wednesday and then move northeast toward western ND and
eastern MT by late Thursday. Best advection of moisture is ahead
of this system as it will contain Pacific moisture, with PWATS
increasing to near 1.5 inch over the area Thursday. Sfc low with
this system will be considerably weaker than the past one, but
still will need to see about track of sfc/upper low as main
rainfall and highest chance of 1 inch or more of rain will be
near the upper low track and this may mean highest chance of 1
inch or more more west than NBM model has. NBM and chances for 1
inch or more of qpf Thu-FRi is 30 pct in Cando area and higher
farther west, and NBM has highest QPF (1+ inch) west central
into north cetnral ND, with under one quarter inch Fargo and
south/east. Regardless though high pops Thursday and more north
for Friday.
Impacts from this rainfall should be minimal, but will
potentially bring issues for farmers involved in the harvest.
Weekend into early next week shows main 500 mb lifting north
with lingering low chance for showers north Saturday and
clearing Sunday.

.AVIATION /05Z TAFS THROUGH 06Z WEDNESDAY/...
Issued at 1132 PM CDT Mon Oct 13 2025
VFR tonight with winds slowly veering northerly to easterly by
mid morning Tuesday. Some rain will move from south to north
mainly impacting DVL, FAR, and GFK in the afternoon with lower
confidence for TVF and BJI. Main impact will be lowering cigs
from some high scatted cirrus tonight to widespread BKN/OVC at
4-6kt by this 21-00z tomorrow. MVFR could looks at least
somewhat likely for FAR and DVL though if timing ends up a
little slower then the TAFS as written will certainly be on the
optimistic side.
