Mid-level ridging is expected across the Central Plains through much of the forecast period. Current 500-hPa analysis shows a ridge axis centered over the area, with a weak shortwave moving through the flow to the west. Energy from this shortwave has led to light showers developing across eastern KS and western MO, however, with a lot of dry air present in the lowest 10k ft, only a few sprinkles have been able to make it to the ground. Cloud cover, tied to the shortwave, is present over the southwestern portion of the CWA and is expected to spread across the remainder of the area through the afternoon and evening, allowing temperatures to peak around 70F today. The ridge axis shifts west this evening and another shortwave is progged to move over the peak of the ridge and into the Central Plains. This will once again allow showers to form across central and eastern KS. The shortwave is expected to be weakening as it approaches western MO, and with dry air still in place in the lowest 10k ft, a few sprinkles remain possible, but it is unlikely that any meaningful precipitation will be seen across the CWA.

Ridging will remain centered just to the west of the local area on Wednesday, as the shortwave moves to the east. At the surface, high pressure over the Great Lakes will result in light southerly winds. Weak WAA and mid-level height rises will yield high temperatures in the mid-70s. By Thursday, the ridge axis will once again be centered overhead, with the height rises and WAA bringing temperatures into the upper 70s through Saturday. On Saturday, a trough will eject across the northern Rockies resulting in lee cyclogenesis in MT. This system will lift northeast into Canada and its cold front will advance towards the Central Plains, but is not expected to make it this far south before stalling out. Although it will remain stalled north of the area, forcing along the front may be enough to see a few showers on Sunday across far northwestern MO, although the chances remain low (15-30%) given the presence of dry low- level air. Another trough ejection on Sunday should be enough force the cold front across the area on Monday, bringing high temperatures back towards seasonal normals in the low-to-mid 60s.

AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/

Issued at 1216 PM CDT Tue Oct 20 2026

VFR conditions are expected at all four terminals through the TAF period. Light SSW winds will back to SSE this evening. A few sprinkles, to perhaps a light shower, are possible this afternoon through the morning hours tomorrow, but chances (10-15%) are not high enough to include in the TAFs. Scattered mid-level clouds will float across the area through the TAF period.
