Storm Center Update – Wednesday PM, April 11


Clouds have been streaming through the KELOLAND region today, with a few light rain showers – mainly in northern South Dakota. Temperatures have been fairly mild nevertheless, with the 40s in the north to the 50s in Sioux Falls and the south. Southwest and south central south Dakota have been very warm, in the mid to upper 60s.

Tonight we will have mostly cloudy skies East River, with drizzle or fog possible as moisture streams into the area. Skies will be partly cloudy in the west. Temperatures will be fairly mild because of the cloud cover, in the upper 20s to upper 30s.

Tomorrow will be mostly cloudy as easterly winds pick up ahead of that well-advertised winter storm system. Tomorrow will be mild despite the clouds, with temperatures in the low to mid 50s. East winds will become brisk in the western part of South Dakota, with a chance of showers from the morning hours on.

The winter storm begins tomorrow night as rain in western South Dakota. Sioux Falls and SE KELOLAND may even get some thunderstorms Friday morning. As strong winds mix colder air into the region, rain will change to snow. Winds will become extremely strong Friday, with gusts of 50 mph possible across much of KELOLAND.

Futurescan of the European model changes most all of the rainfall over to snow by Friday night, and will continue to produce snowfall in eastern KELOLAND through the day on Saturday.

Winter Storm Watches are now posted for western, central, and northeastern South Dakota. Sioux Falls and SE KELOLAND  are in a Winter Storm Watch from Friday night to Saturday night, with the potential for 6-12” of snow, and winds that could exceed 40 mph creating blizzard conditions – especially in open areas.

As we’ve been saying, after the storm exits we’ll have more cold temperatures for at least the next 10 days. We’re hoping for a little warm-up for the final week of April.
