.DISCUSSION...
Issued at 1204 AM CDT Sat Oct 3 2026

There will be just a few hours this morning where, with about 50kts
in the critical layer, Coteau downslope conditions are favored. Flow
above this layer is unidirectional out of the west, so could be some
localized 50 mph gusts on the southeast Sisseton hills/Buffalo ridge
area.

A weak wave crosses the region today, with an environment
ahead of this feature dominated by elevated skinny CAPE in a steep
lapse rate environment with limited moisture. There is a warm nose
below this instability, suggesting only the strongest elevated
convection will result in moisture at the ground, though with the
added wrinkle of the potential for warm microburst type brief gusty
outflows.

Thats about it for interesting weather. Surface high moves into the
region through the day. RRFS and GFS mixed winds top out around 25
to 30kts. Pressure rises only about 5 mb/6 hours.  We remain on the
east side of the high tonight so gradient winds won`t go slack
keeping temperatures from bottoming much cooler than 40F. Return
flow for late Monday/Monday night. Warmest airmass is early Tuesday,
with 850mb temperatures close to +20C before passage of a cold
front. The wave associated with  this one is weak and moves through
the Western Lakes region, so should be dry for us. Northwest flow
transitions to ridging aloft thereafter, so conditions remain
mid/dry for mid-week to late.
