.DISCUSSION...
Issued at 349 AM CDT Sat Oct 4 2025

Current surface observations reflect an environment that would make
one think its June or July in MN/WI versus October. Surface
temperatures as of 2 AM range in the low 70s for a favorable amount
of MN. Its not until you reach eastern MN and western WI where
"cooler" conditions in the low to mid 60s are found. Regardless, for
this time of year. Its hot, and the forecast for the next 36 to 48
hours will remain hot. An area of high pressure remains situated
over the eastern CONUS which continues to direct very warm air up
into the upper MS River Valley. Similar to yesterday`s forecast,
guidance shows high confidence of sufficient mixing down 925mb temps
exceeding +25C which remains near the right tail of the NBM
temperature distribution. Forecast highs will reach the upper
80s to low 90s across much of the state however a few mid 90s
could be felt across western MN later this afternoon. With that
in mind, there are favorable chances that a few sites could set
record for highs as well as warm lows today and tonight.
Increasing southerly winds will also be a factor today and
Sunday. A 45-50kt LLJ will reach MN/WI this morning which will
raise sustained wind gusts ranging from 30- 35kts with a few
isolated 40kt gusts possible. Winds may briefly decrease
Saturday night into Sunday from loss of daytime heating but the
overall trend is elevated winds for much of the weekend. The
combination of dry conditions as well as increased wind speeds
has also raised concerns for elevated fire weather conditions
across much of central and southern MN today.

A surface low will develop ahead of a parent troughing pattern in
the western CONUS. The low is progged ENE`ward and will bring a
trailing cold front late Sunday into early Monday for MN/WI. As
mentioned in the previous discussion, hi-res guidance does hint an
increasing potential of a few scattered showers and
thunderstorms along the frontal boundary given favorable surface
instability. Temperatures on Sunday are expected to not be as
warm (mid 80s) but the noticeable change will be felt on Monday.


Cooler and drier air will fill in the region as the cold front
departs. Forecast guidance maintains warmer MinTs than previous
forecasts for Tuesday into Wednesday which helps decrease
concerns for widespread frost. Although areas across north-
central MN and western WI could see patchy frost Wednesday
morning. For the remainder of the forecast period, southerly
flow returns as well as warmer air. This time however, the
warmer airmass doesn`t appear as potent as our current heat
event.
