T-Storms with Heavy Rain Tonight, Cooler Tomorrow

We have one more 80 degree-ish day before we cool things down for a few days. Today will be partly cloudy with highs ranging from the low 80s in Sioux Falls and across the Tri-State area to the mid 70s across central and northern South Dakota.

A low pressure system moving west to east along the Nebraska/South Dakota state line today and tonight will bring a chance of late day and nighttime thunderstorms. While some storms could be packing hail and strong straight-line wind gusts, the overall severe weather threat is low. There is, however, the potential for heavy rain. Some places could get one-half inch to an inch or more of rain with storms that move through late today and tonight into tomorrow morning.

Behind the system, temperatures are going to drop considerably. Tomorrow will be mostly cloudy and breezy with high temps in the mid to upper 60s along I-29. High temps will only reach the low to mid 60s across southwestern Minnesota tomorrow.

The weekend will be cooler with scattered showers and thunderstorms possible. Highs will be stuck in the low to mid 70s on Saturday and Sunday. We will dry out and warm up next week. By Monday and Tuesday highs will be back in the 80s.TODAY

TONIGHT

TOMORROW
