DISCUSSION

Issued at 146 PM CDT Wed Oct 7 2026

A weak surface boundary is moving through the area today without much change to conditions. A ridge builds in behind the boundary tonight, which will maintain clear skies and light winds. Temperatures stay on the warm side of average for the rest of the workweek with a return of southwesterly low level winds and as an upper ridge remains centered just south of the area. Dew points around 60 degrees during the afternoon hours will also contribute to a summer-like feel for now.

The big weather story late this week and this weekend will be the current Tropical Storm Isaias that is strengthening in the Gulf and expected to make landfall near Mobile, AL. The system looks to quickly move inland toward the intersection of the Ohio and Mississippi Rivers. While eastern KS will likely not experience impacts with the system currently expected to stay east of the area, rain could occur as close as Columbia or Springfield, MO. Changes to our ambient conditions look more probable during the middle of next week as a deep closed low system moves over the southwestern CONUS. Long range models continue to show different evolutions of the low, however, confidence is high on increases POPs next Tuesday and Wednesday. While there also remains a large amount of spread on expected temperatures during that timeframe, trends do suggest more seasonable conditions.

VFR conditions are expected to be the rule. With modest surface high pressure building into the region and clear skies and light winds, there is some concern for BR and MIFG formation in the 06Z-14Z window, but the lack of a strong correlation between winds being light enough winds in the boundary layer and high surface RH, as well as dry ground conditions, suggest keeping any mention out.
