.DISCUSSION...
Issued at 241 PM CDT Mon Sep 29 2025
...Synopsis...
Upper ridging over the Upper Midwest will continue into the
mid-week period before starting to deamplify as we approach the
weekend. The current stalled frontal boundary draped across the
central CWA will lift north towards the international border
tonight. Trust in CAMs is pretty low, but should be at least
some isolated showers and thunderstorms mainly along the
Canadian border. Surface troughing deepening to our west should
help boost south to southeasterly winds tomorrow and Wednesday.
Can`t rule out a bit of stray convection in the far north with
the very warm temperatures and various tiny waves coming through
the southwesterly flow aloft. However, think the best
precipitation chances will hold off until Friday with the
western upper trough starting to approach and a frontal
boundary coming down. Probability of CAPE values over 1000 J/kg
for Friday are less than 30 percent but CIPS analogs have a
small area of 10 percent for severe so will have to keep an eye
out for stronger storms. Another trough coming through should
bring some fairly robust precipitation Sunday, with instability
looking minimal. Cooler temps into the weekend as heights come
down and surface ridging builds in for Monday.
...Unseasonably warm temperatures through Thursday...
With upper ridging and southwesterly flow, the unusually warm
weather will continue through at least Tuesday, Wednesday and
Thursday. ECMWF EFI has 80th to 90th percentiles across
portions of our area through the mid-week period. While it is
unlikely that we will get above 90 degrees, as NBM probabilities
are only around 20 percent in a few spots, highs will remain at
least 20 to 25 degrees above average. The record for Thursday in
Fargo is 90 and doesn`t seem at this point we will get that hot,
but other records in the mid 80s are well within reach.

.AVIATION /18Z TAFS THROUGH 18Z TUESDAY/...
Issued at 1242 PM CDT Mon Sep 29 2025
All sites VFR with some mid and high clouds. Any convection is
expected to stay either north or south of our airports. Winds
will be the main issue, picking up from the southeast as a warm
front lifts north towards the international border. Some sites
still reporting light and variable but think they should steady
out of the southeast by late afternoon or evening. Some increase
in speed to 12 kts or above is possible by the end of the
period.
