Drier, Canadian air feels pretty nice in late July. Usually, these fronts signal a temporary break in the humidity that fuels heavy summer downpours. That’s a trend we’ll be watching in the coming days.
Sioux Falls has had over 150 percent of normal rainfall the past 30 days. Most areas are at or above normal, especially the far western and far eastern areas of KELOLAND. In the middle, we find an emerging dry pocket southwest of Pierre that needs to be watched.
As long as the drier, Canadian air is in place, heavy rain is not a big threat. However, the pattern does show signs of changing next week. Higher dew points indicate areas of deeper summer moisture. We’ll notice more humidity building into the plains late next week.
If we get teased with more humidity, rain chances will likely come back and that will be a trend we’ll watch in August.
