Storms with heavy rain possible this weekend

Written by Shawn Cable Friday, May 18, 2012 | 7:09 am

Where does the time go?!? It’s Friday and the weekend is almost here. It’s going to be another very warm, windy day. Afternoon temps will be back in the 90s with strong south wind gusts to 35 mph at times.

I know there’s a lot of stuff going on this weekend… Graduation parties, open house weekend at South Dakota State Parks… Whatever your plans, I’m sure you’re wondering about the storms we’ve been forecasting for this weekend. Here’s the scoop:

Storms will develop across the Black Hills and westernSouth Dakotalate this afternoon and this evening. Those storms will move east into centralSouth Dakotaby about 10 or 11 pm tonight. Scattered storms will continue to move east through the night with a slight chance of scattered storms along and east of the James River, includingSioux Falls, by morning. Saturday will be partly to mostly cloudy with scattered showers and thunderstorms redeveloping along theJames Riverby early to mid afternoon. Storms will quickly develop into a line that sweeps across easternSouth Dakotaduring the late afternoon hours on Saturday and intoIowaandMinnesotaSaturday evening. As of right now, it looks like the best chance of thunderstorms inSioux Fallsis between 3:30 and 7:30 pm.

While a couple of these storms could bring large hail or 60+ mph straight-line wind gusts, I think that the more significant threat is the possibility of heavy rain. 1-2 inches of locally heavy rain is possible as these storms move through.

Severe WX Again Today: Tornadoes Possible

Written by Shawn Cable Saturday, May 5, 2012 | 4:51 pm

Significant Severe Weather Risk across southeast South Dakota, northwest Iowa, eastern Nebraska and southern Minnesota late this afternoon and tonight.

Storms will come in two rounds. The first will be late this afternoon and this evening. Supercell thunderstorms will develop across northeast Nebraska and southeast South Dakota and move northeast. These storms will have a significant potential to produce large, damaging tornadoes. Baseball size hail and 70 + mph wind gusts are possible with these storms.

The second round will come late tonight. A line of thunderstorms will move across South Dakota late tonight… Probably reaching Sioux Falls after 10pm. Damaging straight line wind, large hail and isolated tornadoes (especially south of I-90.)

Stay tuned for the latest updates. KSFY has 9 chase teams spread out across northeast Nebraska and southeast South Dakota waiting for the storms to develop.   I’ll be tweeting until the storms end.
