.DISCUSSION...(Today Through Saturday)
Issued at 117 AM MDT Sun Nov 2 2025

Progressive westerly Pac flow will support mild conditions
through most of the period as a series of weak low pressure
systems traverse the Northern Plains. Breezy southwest winds have
developed over much of the area ahead of the approaching sfc
trough/cool front. This has resulted in temps warming up at many
places. Cool front will move into the FA this morning with
increasing NW winds. Winds will reach adv levels for part of the
day across far NW SD given pressure rises, mixing, and fast flow
aloft. Hence, have issued a wind adv for this although it will be
marginal. Otherwise, mild today with highs in the 50s to low 70s,
warmest over southern SD. Not much cool air with this system, just
enough to knock temps down about 10 degrees for Monday compared
to today most places. Dry weather expected most of the period
given lack of any appreciable moisture with any of these systems.
A stronger mid-level trough will progress through the region Thur
and again later Friday. These systems may bring enough lift to
support some rain or snow then, esp over the northern Black Hills
Friday. Temps will remain at or above normal

turn northwesterly after 12z behind a cold front, with wind gusts
increasing behind the front to 25-35 knots through the end of the
forecast period; strongest winds across the western SD plains.
Winds will taper off after 00-02z Sunday evening.
