SIOUX FALLS, S.D. (KELO.com) — Here comes the heat!
The National Weather Service in Sioux Falls has issued a Heat Advisory for the KELO Radio listening area:
…HEAT ADVISORY IN EFFECT FROM NOON TO 9 PM CDT TUESDAY…
…EXCESSIVE HEAT WATCH IN EFFECT FROM WEDNESDAY AFTERNOON THROUGH WEDNESDAY EVENING…
* WHAT…For the Heat Advisory, heat index values up to 105 expected. For the Excessive Heat Watch, dangerously hot conditions with heat index values up to 107 possible.
* WHERE…Portions of central, east central, south central and southeast South Dakota, northeast Nebraska, northwest and west central Iowa and southwest Minnesota. This includes the Tribal Lands of the Yankton Sioux Tribal Nation and the Flandreau Santee Sioux Tribal Nation.

Weatherology meteorologist Michael Karow says we’re on the eastern periphery of a big high-pressure system that’s still stuck over the western US.
Karow says a high dew point will make the high temperatures feel even stickier the next few days– but it could be even hotter.
He says central South Dakota usually has ten 100+ degree days each summer– a mark the area has already been reached, and there is August yet to go.
