Tonight is the night to cover your tomatoes, petunias, marigolds or any other plants you want to live another day. It is going to get cold tonight. A Freeze Warning is in effect for most of central and eastern South Dakota, western and central Minnesota and extreme northwestern Iowa. By tomorrow morning, temps will drop into the upper 20s to near 30 degrees in Sioux Falls while temps across northern South Dakota drop into the low 20s. Temps will drop into the low to mid 30s again tomorrow night, after that I don’t think frost will be a threat for the rest of the week.

A system to our south will keep Sioux Falls in the Tri-State region mostly cloudy today. Clouds will gradually roll out late today into this evening. Central and northern South Dakota will see a few clouds early with plenty of sunshine this afternoon. High temps will reach the low to mid 50s this afternoon.

The rest of the week is lookin’ good with plenty of sunshine and warming temps. By Thursday most places will warm into the upper 60s to low 70s. The weekend will be a bit cooler with a few scattered showers possible on Saturday.
