Storm Center Update – Tuesday PM May 7

Forecast

Clouds have overspread KELOLAND today, with a broad area of rain showers now moving from southwest to northeast across the region. Rainfall is light to moderate, so amounts have so far been under a half inch. But persistent rainfall will cause those amounts to grow over the next couple of days, and a large, wet spring storm system affects much of the central U.S.

Tonight we will see widespread light to moderate rainfall across KELOLAND. With a northeast breeze we will see temperatures drop to the upper 30s to low 40s. Rapid City will have rain and fog, and there is a Winter Weather Advisory for the Black Hills.

Tomorrow will be cloudy, rainy, breezy, and cooler. With the rain continuing most of the day, highs will only be in the upper 40s to low 50s, which is close to twenty degrees below normal. NE winds will strengthen, to 15-25 mph in Sioux Falls and SE KELOLAND.

Rainfall will continue tomorrow night and then end Thursday morning. Due to the persistent rain, we could see two day rainfall of an inch to an inch and a half in Sioux Falls and SE KELOLAND.

With rains ending Thursday, we’ll see brisk north winds keeping us cool Thursday afternoon. Highs will be about ten degrees cooler than normal, in the mid 50s. Rapid City will be a bit cooler, with Thursday morning snow showers.

Skies should be sunny on Friday, and we will warm to the upper 50s to low 60s.

The weekend will warm to near-normal readings for Mother’s Day weekend. Saturday’s highs will be in the mid 60s, with a chance of hit and miss light rain showers. Sunday looks mostly sunny and dry, with temperatures in the mid 60s East River to the upper 60s West River.

Sharply warmer air looks like it will be coming in next week, starting on Monday and Tuesday when much of KELOLAND should be in the 70s. Temperatures should be near or above-normal every day next week. We will finally have a prolonged run of warm spring weather.
