Sioux Falls, SD
More Rain Ahead Today…Warmer Weather For the Weekend…Storms Sunday Night…
Showers and t-storms continue this morning with the heaviest totals southeast of a line from Ivanhoe to Sioux Falls to Tyndall and point southeast of that line. As of 6am, Sioux Falls reports about .82”, south side of Sioux Falls 1", and around 1.5” in Worthington.
Scattered rain continues to develop in southwestern SD this morning and this activity will spread to the northeast during the day, so Pierre and Aberdeen will see more scattered showers. Sioux Falls will also see some of this activity during the afternoon hours. A break in the rain is forecast tonight and early tomorrow, but a developing warm front will spark more showers tomorrow afternoon from south to north. Thunderstorms will increase in both coverage and intensity tomorrow night and Saturday. Some of these could also become severe. Much warmer weather will develop in southern KELOLAND Saturday afternoon with 90s near the Nebraska border, with only mid 60s in Aberdeen. The rain is most likely north of the warm front. Additional storms are possible Saturday night near the warm front, some severe with large hail. This would most likely be north of Sioux Falls.
Sunday will be warmer in most areas of KELOLAND, but storms are expected to fire late in the afternoon along a cold front. The best bet of severe weather will be east of the James River Valley. The rain will end by Monday morning, with a pleasant Memorial Day in the forecast.
