sioux falls, sd
Areas of fog have developed in southeastern KELOLAND with some visibilities dropping below a ¼ mile.
The fog should be mostly gone by 9 a.m. as winds increase from the southwest and turn around to the northwest through the afternoon.
It will be a mild day with highs in the 30s in many areas east of the James River, with 40s in the central areas, and near 52 in Rapid City. Winds this afternoon will be gusty at times with wind speeds at 15-30 miles per hour and higher gusts in SW Minnesota. Enjoy the mild weather now because it will be going away this weekend.
Highs tomorrow will fall into the 20s in the southeast and just 13 in Aberdeen. Pierre and Rapid City will also see much colder weather along with chances of light snow showers.
I expect more chances of snow by Sunday afternoon into Monday as the next disturbance arrives from the northwest. We’ll be watching the details of the forecast as this system has the potential to stall Monday and Tuesday. There are two storms: one in the southern branch of the jet stream moving through California; the other, the northern stream system set to arrive in KELOLAND from Canada. If the northern branch stays dominate, we’ll have mostly nuisance type snow (1-3”) and it will get very cold by Monday and Tuesday. The southern branch of the jet stream will fuel a big storm to our south early next week, which could stall the system affecting us. I would pay attention to that pattern to see if we end up putting some more snow into the forecast for Tuesday as well.
One promising sign is the cold air modifies by the end of next week on all of our long range models.
