How common are 90 degree days in May?
SIOUX FALLS, S.D. (KELO) — With the warm forecast, Meteorologist Scot Mundt has a look at how common it is for KELOLAND to reach 90 degrees in May.
Warm and dry conditions are in the forecast for the week and beyond for many, if not all, of central and eastern KELOLAND. With the dry conditions, temperatures will remain well above average with highs in the 70s and 80s. There's even a chance that some will reach the 90s.
988 signs part of Mental Health Awareness Month
Right now, the best chance at the 90-degree heat is in western South Dakota. This may happen on Mother's Day. Otherwise, expect the 80s for just about everybody else.
To reach 90 in May isn't too uncommon. The climate average is for 1 90-degree day in KELOLAND. Yankton and Winner average 2 days with 90-degree heat in May.
And those types of temperatures will continue into at least the first half of next week. After that, we're watching for subtle signs of cooler air and moisture.

Hot and humid weekend with the potential for strong Sunday storms
NEW ORLEANS (WGNO) – Highs in the low 90s this afternoon. Mostly sunny skies to start off the day with a few clouds beginning to develop around lunch time. Chance or isolated shower activity for the afternoon and early evening. Shower chances come to a close ahead of sunset. Saharan dust makes an appearance this Saturday. Milky skies will be seen as the dust particles scatter more of the sunlight. A trough passing through the central U.S. dips southward on Sunday. This is likely to trigger thunderstorm development as early as Sunday afternoon. While this will provide some relief from the heat, they will have have the potential to be strong or even severe. Unlike the rain that we have seen the past few afternoons, Sunday's storm chances will have a different origin, forming from a different reason. The greater upper level support along with our hot and humid environment is what gives these storms on Sunday a bit more potency compared to the 'pop-up' showers we have seen all week. Greater potential for storms will be on the north shore. We turn to a more active weather pattern next week. Many chances for showers and storms. This allows for temperatures to fall out of the spotlight with highs in the 80s. Copyright 2025 Nexstar Media, Inc. All rights reserved.

Severe thunderstorms likely on Friday
(SOUTHERN COLORADO) — Thunderstorms are expected again over Southern Colorado on Friday, and some of them are going to be strong. There's a lot of wind shear in the atmosphere today, and that is going to help storms rotate. When storms spin, they organize and strengthen. The spin in the storm's updraft helps it to stay separate from the downdraft — this often results in large hail, and that is our biggest threat today. Most of the storms will move east, but any that start to turn to the right, and start heading east-southeast or southeast, may become capable of producing a tornado. A severe thunderstorm and/or tornado watch will likely be issued for parts of Eastern Colorado later on today. A WATCH means that ingredients are present for the possible formation of severe thunderstorms, and you should pay attention. It's similar to Mom or Dad putting the ingredients for tacos out on the kitchen counter – get ready. A WARNING is like the tray of assembled tacos arriving at the table – it's time to take action! Know the difference and be ready later today. Download the FOX21 StormTeam app for Apple or Android to get a digital door knock from us in the weather center when storms are heading your way.

Storm Team 3: Back to sizzling heat with strong afternoon storms
Let's have a fabulous Friday! After a 2-week break from 90-degree temperatures, the sizzling heat returns today with highs in the lower 90s. Heat index values will also climb into the upper 90s this afternoon. As of the chance of rain, we can't get rid of it completely due to some lingering moisture from Wednesday's coastal low. The coverage will be lower than the mid-week widespread rain we saw. Only isolated showers and t-storms are possible here and there in the afternoon and evening. Due to the extended threat of severe storms, Sunday has been upgraded to a Weather Aware Day to accompany Saturday's Aware Day. Scattered strong and severe storms are possible across both afternoons and evenings. Not a washout either day, but have a back up indoor plan in case storms head your way. Tomorrow will start dry with muggy temperatures in the lower 70s. Temperatures will quickly jump into the low to mid 90s for highs. Heat index values will be in triple digits. By the early afternoon, scattered storms will begin to fire up. Strong and severe storms are possible through the late afternoon into the overnight hours before rain tapers off. Our main impact will be damaging wind gusts of 60+ mph. Sunday will be a rinse and repeat of Saturday with scattered strong and severe storms possible across the afternoon and evening hours. High temperatures will once again climb into the mid 90s with feel-like temperatures reaching the triple digits. Stay hydrated and keep an eye on the sky. This weekend will not be a washout. There will be plenty of dry slots to be outside, just keep an eye on the sky. Rain will be heavy at times as well – this could lead to localized street flooding. Saturday and Sunday will be two of the hottest days the year so far with highs reaching the mid 90s outside of rain showers. Our hottest day of the year so far was on May 16 with a tied record high of 95. More of typical summertime pattern will continue through early next week. Copyright 2025 Nexstar Media, Inc.
