.DISCUSSION...
Issued at 257 AM CDT Sun Oct 5 2025
Morning `lows` are all but that early this Sunday morning.
Temperatures are in the low to mid 70s across southern Minnesota
and west-central Wisconsin with very few clouds in the sky. As
mentioned in the previous discussion, normal HIGH temperatures
this time of year are in the mid 60s. Highs today will still be
able to reach the low to mid 80s with the support of the
thermal ridge, but it won`t be nearly as warm as Saturday`s
record breaking heat. Winds remain strong and southerly, with
gusts across Minnesota into the 30-35MPH range. The low- level
jet will support the continuation of these gusty winds through
most of the day today until the frontal passage shifts winds to
the northwest and knocks them down quite a bit. Another Special
Weather Statement will be in place for most of the day (across
Minnesota) due to the breezy sustained winds.
Taking a look at the precipitation chances today, you can see
what is to come across South Dakota this morning: scattered
showers and a few thunderstorms. Guidance isn`t in very good
agreement with chances for anything before noon, but there are
a few outliers that do show a line of light precip moving across
southern Minnesota around 9AM. While these pre-frontal chances
can`t completely be written off (less than 20%), the greater
chance for precip is this afternoon when the cold front and
surface low pass through. Forecast soundings show modest
surface-based instability, which should be enough to support
showers and a few rumbles of thunder this afternoon. As far as
coverage goes, things will be scattered with the possibility of
some of the precip not reaching the ground. Taking this into
consideration, any precipitation amounts will remain light. The
area most favored for rain chances (50%) is along and east of
I-35 by mid to late afternoon (3PM onward). All will be out of
the area (and windows can finally be opened!) by the time most
go to bed tonight.
Monday will start off with quite the contrast to this morning:
temperatures in the 40s to low 50s. Dewpoints will be about 10
to 15 degrees lower, creating a typical crisp fall morning. High
pressure will continue to build in through early week, allowing
pleasant weather for early October. Given forecast clear skies
and lows in the 30s and 40s Tuesday night, patchy frost is to be
expected in outer lying areas, particularly across central
Minnesota and northwest Wisconsin. Southerly flow will return
for the second half of the week as the surface high pressure
departs, bringing above normal temepratures and a few precip
chances back into the forecast.

.AVIATION /12Z TAFS THROUGH 12Z MONDAY/...
Issued at 617 AM CDT Sun Oct 5 2025
The LLJ will continue to give strong southerly 30-35kt gusts
through much of the daylight hours today. Winds will decrease
this evening as a cold front passes from NW to SE across all
sites. Wind gusts are expected to fall below 20kts around or a
few hours before midnight. Later this afternoon, will need to
monitor the potential development for SHRA/TSRA during FROPA.
Coverage looks best for our WI sites, but introduced PROB30 at
MSP an MKT as well. It is possible that precip mentions may need
to be amplified to mention thunder, but have opted to leave out
the mention at all sites but EAU. VFR condiitons through theperiod,
with any showers expected to keep vis 6SM or greater in
addition to cigs greater than 030.
KMSP... HiRes guidance and current radar reflectivity indicate a
brief a period of precip near the terminal around 14z this
morning, but the surface environment is likely too dry for this
activity to reach the ground. Will continue to monitor and AMD
as necessary. Best chances for precip continue to be for this
afternoon in the 19-22Z frame.
/OUTLOOK FOR KMSP/
MON...VFR. Wind NW 5-10 kts.
TUE...VFR. Wind NW 5-10 kts.
WED...VFR. Wind S 5-15 kts.
