Hope you got the chance to make it outside at some point on Friday because there are big changes coming in.
We’re sunny and dry, with a strong WSW breeze. Believe it or not, we’ll actually be back above-average by day’s end. Obviously, most of this month has been on the chilly side and Saturday will be no different. A strong, sweeping cold front is pushing our way from North Dakota and will offer up cool conditions tonight and a cold start to your weekend.
This is more of a wind and temperature change, as opposed to a big storm. There is very little moisture attached to this and this will likely be a dry passage. Still, after clear skies Friday night and Saturday will be partly cloudy and 10-20 degrees colder than Friday. Northwest winds behind the front won’t be quite as breezy, though you’ll likely feel them at times.
Sunday is a bounce in the other direction. We’ll warm back into the upper 50s in some cases, with partly cloudy skies overhead.
The workweek is definitely the tricky part of the forecast. A system comes out of the west early Monday. That brings Rapid City and the west a chance of wintry mix. Several inches of snow are possible up in the Hills but models really disagree on how much, where and when the snow will fly. Pierre is also in line to see some mix later in the day, though by then it could be a touch warmer.
This continues to move east Tuesday, impacting Sioux Falls and Aberdeen. The chances are lower in the east, though, as we head into Tuesday. Wednesday should be a brief break, though it will be cloudy and cold. A more well-defined storm complex comes out of the southwest Thursday and Friday. This time, warm south winds should keep most with a rain chance. As of NOW, the system takes a flatter, WSW to ENE track into southern KELOLAND but that could change. Cold winds behind the storm will ensure another late October cool-down.
