.DISCUSSION...(This Evening Through Saturday)
Issued at 148 PM MDT Sat Nov 1 2025

Highly amplified pattern with a large area of low pressure sitting
across the central plains and a ridge axis encompassing much of
the western CONUS remains the focal point regarding the
observational weather expected across western South Dakota and
eastern Wyoming for the upcoming week. High cirrus are spilling
over the ridge axis allowing for temperatures to no rebound as
much today with temperatures holding into the upper 40s to low 50s
across the region. Embedded in this upper level flow are weak
shortwaves that will push weak fronts through the region with
several fronts progged to push through the area over the next 5
days. The first arrives tomorrow and this will be a fast moving,
dry front that will bring slightly cooler temperatures but
noticeably stronger northerly winds to portions of northwestern
South Dakota. This area will need to be watched for the
possibility of Wind Advisory issuance. The next front will follow
suit and come through Tuesday and bring slightly cooler
temperatures and breezy conditions. Overall the pattern looks mild
and dry until potential a strong, deep trough moves into the
region and brings the chance for high elevation Black Hills snow
showers and valley rain showers back into the forecast by next
weekend.
