Storm Center Update- Monday PM, April 24th


There were a few hundredths of an inch of rainfall in Sioux Falls and SE KELOLAND this morning, and there have been some sprinkles in NE South Dakota this afternoon. But the big story is the approach of colder air, cold air that is going to remain over this area the rest of this week and most of next week, too.

The cold front will come through I-29 this evening, and temperatures will drop as a result. Overnight lows will be in the 30s to low 40s… with only patches of clouds to prevent temperatures from bottoming out altogether. Rapid City will be down around freezing, as a Winter Storm Watch is posted beginning tonight.

Tomorrow will be cloudy and colder across KELOLAND, with north winds bringing in chillier air. There is a good chance of rain showers East River, though amounts should be limited to a few tenths of an inch, and mostly in Sioux Falls into northwest Iowa. Highs will only be in the 40s East River. Western South Dakota will only be in the 30s, with snow possible most areas west of the Missouri River. Rapid City could see a few inches of snow.

We’ll keep rain showers in the forecast East River on Wednesday, with morning temperatures in the 30s – so it’s possible that a few flakes of snow could mix in, but more rain than anything else.  With abundant clouds during the afternoon, we’ll keep below-normal high temperatures only in the 40s.

Thursday is also looking cloudy, with highs in the 40s East River to low 50s West River. The next band of rain will enter western South Dakota during the day.

The weekend will also be colder than normal. It will be mostly cloudy on Friday, with highs in the mid 50s, and a little colder in the west where snow will again be possible. We’ll have more chances for rain Saturday and Sunday, which will also be a little breezy and cool, with highs in the upper 40s to low 50s across KELOLAND.

Temperatures will be a little warmer next week, in the 50s for the first few days of May. But we don’t see temperatures returning to normal – 60s East River – until perhaps Friday or the weekend.
