Showers and thunderstorms will exit our region from west to east this morning. The sun will gradually claw its way out from behind the clouds this afternoon and it will be cooler and not as humid. High temps will range from the low to mid 80s with a light northeasterly breeze.

The rest of the week and the weekend will be sunny and comfortable. High temperatures will hold steady in the low to mid 80s into next week.

Get ready for another day of extreme heat and humidity. Today will be partly cloudy with highs in the mid to upper 90s. When you factor in the humidity, the heat index will soar above 100 degrees for much of the afternoon.

A cold front will move across the Dakotas later today, tonight and tomorrow and that will bring a chance of thunderstorms. Storms will develop across central and northern South Dakota late this afternoon and this evening and move east overnight tonight into tomorrow. Some storms will be severe with large hail and strong straight-line wind gusts being the main threat. A tornado or two is also possible. In addition to severe weather, storms will also have the potential to produce heavy rain. An inch or more of rainfall is possible through tomorrow morning.

There is a slight chance that we could see a few scattered thunderstorms in the Sioux Falls area by mid to late evening, however thunderstorms are more likely to develop late tonight and continue through tomorrow morning.

After tomorrow, the rest of the week and the weekend will be mostly sunny and dry. High temps will stay in the low to mid 80s through the weekend.

It is going to be another warm and humid day. Afternoon temperatures will range from the upper 80s to low 90s, but the heat index will soar back into the mid to upper 90s for many.

Another system will bring a chance of thunderstorms late today and this evening across central and western South Dakota. Thunderstorms will move east overnight tonight into tomorrow morning and then redevelop across parts of eastern South Dakota, Minnesota and Iowa tomorrow afternoon and evening. Once again, some storms could be severe with the potential for heavy rainfall amounts of one-quarter to one-half inch or more.

The weekend ahead will be sunny, cooler and not as humid. Highs will still reach the upper 80s to low 90s on Saturday, but afternoon temps will drop into the low 80s by Sunday. The cooler 80s will stick around into next week with a chance of showers and thunderstorms by late Tuesday night into Wednesday.

TODAY
Partly cloudy, warm and humid. High: 88°. Wind: Northeast becoming east 5-15 mph.

TONIGHT
Partly cloudy with scattered thunderstorms possible. Low: 71°. Wind: Southeast 5-15 mph.

TOMORROW
Scattered thunderstorms possible in the morning and again late in the afternoon and evening, otherwise partly cloudy, warm and humid. High: 92°. Wind: Southeast 5-15 mph.

It is going to be a brutally hot and humid day. A Heat Advisory is in effect for today across much of central and southern South Dakota. In Sioux Falls, high temps will reach the mid 90s with the heat index approaching 105 degrees through much of the afternoon. Across Central South Dakota, it will not be as humid but actual temperatures will soar to between 105 and 110 degrees.

Our other concern with today’s weather is the potential for strong to severe thunderstorms late today and tonight. Thunderstorms will develop across central and northern South Dakota late this afternoon and move southeastward through the evening and overnight. Storms could be severe with the main threats being large hail and damaging straight-line wind, however, a tornado is also possible. In addition to severe weather, there could also be areas of heavy rain. One-quarter to one-half inch or more of rain will be possible with any storms that develop.  

As of right now, I think storms will develop across central and northern South Dakota late this afternoon into early evening and move southeast into Sioux Falls by mid to late evening. The timing could change a bit, stay with us for updates throughout the day.

TODAY
Mostly sunny, hot and humid. High: 94° with the heat index approaching 105°. Wind: Southeast 10-20 mph.

TONIGHT
Thunderstorms likely. Some could be severe with heavy rain. Low: 70°. Wind: Southeast 5-10 mph.

TOMORROW
Partly cloudy, warm and humid with scattered storms. High: 90°. Wind: East 5-15 mph.
