Clouds are on the increase across our area but the overnight hours should remain very dry and mild. The biggest weather development of the week arrives tomorrow and pushes much cooler Canadian air in by Monday.
For the rest of tonight, clouds will eventually diminish from west to east although we’ll keep it partly cloudy. Most will eventually fall to around 50 degrees.
The cold front we’ve long talked about still looks like it will stall just north of Sioux Falls. That means most of KELOLAND will be somewhat cooler and cloudier but Sioux Falls should be about the same as today. Rains will be well behind the actual change in wind direction and that could sap some of our potential rains as the air will be dry underneath the clouds. The onset of rains should come along the ND-SD border by the middle of the afternoon. This will advance into NE South Dakota by later in the evening. The good news is that some light moisture amounts are being pulled a little farther west but we don’t expect to see anything more than light showers West River. The best overall chance for rain is in far east-central KELOLAND, in areas like Brookings and Watertown. That will come during the overnight tomorrow into Monday. Most of the rain should be moving out of the area by late Monday morning. There is a possibility of a few storms mixed in, but most of this will remain showers.
Much cooler air finishes moving in Monday and 60s will last most of the coming week. It should be fairly quiet and dry although there will be cloudy periods. We could see some light rains Thursday into Friday but the chances aren’t looking good enough to include now.
Have a great Sunday!
