Issued at 1146 PM CDT Mon Jul 27 2026 The forecast period begins with a broad upper ridge still extending from the Big Horn Mountains and Black Hills to over the Great Plains. Temperatures have cooled down a bit and heat index values have fallen below Heat Advisory Criteria. Therefore, the Heat Advisory and Extreme Heat Warning have been allowed to expire for the entire CWA. With the placement of the ridge, wildfire smoke is expected to impact the region. We are not currently expecting any major impacts to visibility; however, some hazy skies and a faint smell of smoke may be possible overnight into Tuesday morning. Cloud cover increases overnight, along with our chances for a few showers/storms. A weak shortwave trough will move into the area later tonight bringing a chance (20%) for a few isolated thunderstorms across our area. Any storms that are able to make it into our area may have the potential of producing some strong wind gusts. Cloud cover sticks around Tuesday morning, decreasing into the afternoon. A few models try to bring in some isolated showers/storms in the morning, with those chances diminishing heading into the afternoon. We will finally see some relief from the dangerous heat Tuesday afternoon with highs only reaching up into the upper 80s to low 90s. A few models try to bring in some chances (20%) for a few showers/storms Tuesday afternoon. Wednesday, the ridge shifts east slightly with high pressure over New Mexico, eastern Colorado and western Kansas. Expect another warm day with highs once again topping out in the mid-80s to low 90s for most areas. Expect a pattern shift on Thursday as low pressure develops to our west. This system will move across Nebraska during the day, tapping into warm, gulf moisture and bringing it north into the region. There will be chances for showers and storms during the day and into the evening hours. Models are showing precipitable water values of at least an inch with several showing potential for 1.5" or more. We`re still a few days away from the event, but if this trend continues and thunderstorms develop, we may need to monitor for localized flooding potential. Shower/thunderstorm chances continue into Friday, tapering off west to east as the system moves into central Iowa and Minnesota. Enjoy some cooler temperatures as highs stay in the 80s across the region and lows Saturday morning fall into the low to mid-60s. The cooler air sticks around through the weekend with highs mainly in the 80s and lows in the 60s. && .AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/... Issued at 533 AM CDT Tue Jul 28 2026 VFR conditions should prevail for the duration of the TAF cycle. An area of showers and storms near the KLNK terminal will slowly push southeast with only lingering mid to high level cloudiness expected at all terminals. Winds remain under 12 knots and from the northeast, turning southeasterly by the afternoon and largely becoming under 5 kts late in the period. A few scattered showers and an isolated storm may develop after 21z and affect KOMA and KLNK, but chances remain less than 10% for development at this time. && .OAX WATCHES/WARNINGS/ADVISORIES...
