.DISCUSSION...
Issued at 314 PM CDT Tue Sep 29 2026

Zonal flow will prevail through Wednesday with continued above
average high temperatures ranging from the mid 60s F in the
north to mid 70s F in the south. Surface low pressure over
Canada will move into the Hudson Bay region Wednesday bringing
in high pressure and cooler temperatures behind it by Thursday
morning. From Thursday through the weekend, seasonable
temperatures with highs in the mid 50s to low 60s F and lows in
the mid 30s to mid 40s F are expected.

The next chance for precipitation is Saturday as a 500 mb wave
from Montana moves southeast. Atmospheric lift and southerly
winds advecting in moisture will be enough to bring 20-50%
precipitation chances with the highest chances being in
Northwest Minnesota. This event is expected to be minor with a
10-40% chance of getting greater than 0.25 inches of rain. High
pressure moving in behind the Saturday system is expected to
bring cooler overnight lows Sunday and Monday with temperatures
in the 30s F. Monday morning looks the coolest, though the
chance for a freeze remains low (0-30%) for much of region.

As we move into next week, especially Tuesday, ensemble systems
are generally indicating that above average heights will return
to the region bringing above average temperatures. From the Red
River Valley and west, there is a 30-60% chance of seeing a
high temperature of 70 F or greater Tuesday. Dry conditions are
also favored for next week.
