.DISCUSSION...(This Evening Through Wednesday)
Issued at 141 PM MDT Wed Oct 8 2025
Upper level analysis shows ridging over the central US with
southwesterly flow aloft across the western half of the country.
Upper level high pressure continues to build across TX and the
southern Plains. Surface high pressure is centered over northern
WI with a tight surface pressure gradient over the Northern
Plains. Strong southerly winds have developed across the forecast
area under a stout low-level jet. Sustained southerly winds 20-30
mph with gusts to 45 mph will continue this afternoon and evening
across south-central SD. While transient wind advisory criteria
are expected, will hold off on any wind headlines. The NBM
continues to highlight potential for 50+ mph gusts, although
forecast soundings are not overly impressive. Will continue to
monitor and update should things change.
Upper ridging will persist with above average temperatures and
generally dry conditions through Thursday. A northern stream
shortwave will drop into the Upper Midwest early Friday with a
cool front pushing through the area, although temperatures will
remain in the 60s and 70s. Monsoon moisture will stream into the
area coupled with weak perturbations in the southwest flow Friday,
resulting in chance of showers during the day Friday, although
precipitation amounts will be meager.
Shortwave ridging returns Saturday with temperatures warming to
near 80 across the lower elevations. Potential exists for highs
into the mid 80s, although cloud cover will limit surface heating.
A deep Pacific trough will push through the northwest Friday into
the weekend along with another cold front, bringing active weather
late Saturday through the weekend.
