Warm Air Fights for Control: Temperatures in the 40s and 50s next 7 days

Although we could have a few bumps on Saturday and Sunday, we're expecting otherwise dry and mild weather for the Black Hills.

  • Thursday and Friday will see temperatures in the 40s and 50s across the region – wtih 50s being rare today and more likely by Friday.
  • Dry conditions will persist through Friday evening, giving us a break from the constant barrage of small rain/snow producing systems.

  • A ridge of high pressure has been keeping the west coast dry and warm, but hasn’t had much luck pushing into our region.
  • Over the next 7 days, this will change as the ridge finally makes some progress into the northern plains.
  • A few systems will come through, but overall temperatures will be mild and any systems that do come through will be mostly rain.

  • Saturday present our first speed bump, with a quick moving system in the morning that will bring breezy conditions and rain showers.
  • This system will move from Wyoming and Montana into South Dakota from the Northwest through the morning and into the afternoon.
  • This could also include frozen precipitation in the higher elevations, but impacts are expected to be small.

  • Saturday is the first day of hunting season for West River in South Dakota, and for those wanting to get started right away, make sure you bring your rain boots.

  • The cold front will move through Saturday morning and afternoon, but the first part of Saturday will be cloudy with a few patches of drizzle on the South Dakota Plains.
  • Perhaps a slight mix could take place in areas of Northeastern Wyoming – particularly near the Bighorns.

  • By about 12-3 PM Saturday, more numerous showers and breezy conditions will sweep across the Black Hills and South Dakota Plains.
  • Temperatures won’t necessarily plummet, but they will get noticeably cooler with Northwest winds gusting around 35 MPH.
  • The Central and Northern Hills could see a few snow bands cross through, so don’t be surprised if you get a few inches of snow before all is said and done.

  • Sunday will bounce right back into warmer temperatures in the 40s and 50s with relatively dry conditions for most of the day.
  • By Sunday evening though, another quick moving system will bring showers across the region. These should end by Monday morning.


Our next potential “real” system will be Wednesday or Thursday of next week, where high temperatures could recede back into the 30s. So far the long range looks unsettled – but no hints so far of massive arctic blasts like we saw in October and earlier in November. The eastern portion of the U.S., however, could see several cold & snow producing systems. If you have plans to travel East for Thanksgiving, keep an eye on the forecast over the next couple weeks as unsettled weather does look likely. Happy Friday eve! – Brant
