Rapid City, South Dakota

Fall in the Black Hills is a wonderful time and place. Hopefully the weather will cooperate.

At 852PM, Mountain Time, Rapid City was reporting a temperature of 54 degrees with clear skies. Rapid City was the exception to the rule across the region, where places like Spearfish were reporting overcast conditions. A lee trough was working on becoming more organized across the region, which at the moment only materialized as some mid-layer clouds.
The upper level trough pattern will lead to a pair of surface systems. The first is a stronger area of low pressure, initially, moving through Canada towards Ontario. At the base of the trough, a weaker but rainier feature will develop over the southern Plains. In between and over Rapid City, expect a surface ridge over western South Dakota through the day tomorrow. As the northern part of the upper trough shifts east on Thursday, the threat for rain in Rapid City will increase. The system the south will be drawn north into the primary trough, which in turn will encourage moisture to lift to the north as well. Some of the shower activity will be heavy, and will really become likely in the late evening. Tomorrow will be a cooler day, thanks to the upper trough passage, with or without organized shower activity.
