SIOUX FALLS, S.D. (Dakota News Now) -- While the weekend overall was decent aside from the gusty winds, eyes will be on a storm system that could impact the region later this upcoming week.

We’ll be quiet tonight with a mainly clear sky and winds decreasing to 5-15 mph and gradually shifting from the west and northwest to the east. Clouds increase from southwest to northeast overnight ahead of an upper-level feature that will slide through. Lows fall back into the teens and 20s.

The wave will slide through Monday and looks to spell a few wintry mix or snow showers for those in northern and central South Dakota, otherwise skies will be partly to mostly cloudy with highs in the 40s and 50s. Winds will become breezy out of the east-southeast at 10-20 mph, but 20-30 mph in central South Dakota.

There’s still a lot of uncertainty that remain on what will happen in regards to our next system, but here’s what we know so far. The latest model runs continue to show the system coming through in two waves. The first low pressure system will come through Tuesday into Wednesday, and bringing with it rain showers and a chance for thunderstorms, mostly for the eastern half of the region. The second round will move in Wednesday afternoon and last through the first half of Friday, but this is where we have the most question marks. As of now, the low will track across southeast South Dakota into southwest Minnesota, which means we’ll have snow and a wintry mix to the northwest of the low with rain and thunderstorms southeast. By Thursday night, all the precipitation should change over to snow and last through midday Friday. There is still lots of uncertainty at this point in regards to the track, timing and how much precipitation will fall, so please stay with the First Alert Weather Team for the latest details as the forecast will likely change over the next few days. The good news is the models continue to show most areas seeing 0.5-1.5″ of precipitation with isolated higher amounts, so that will help with the ongoing drought concerns.

What’s more certain at this point is there will be a sharp drop in temperatures in wake of this system heading into next weekend with highs in the 20s and 30s with lows in the single digits and teens.
