DISCUSSION

Issued at 347 AM CDT Wed Apr 29 2026

Surface high pressure continues to build and slowly move southeastward heading into the morning hours of Wednesday. This will keep skies mostly clear trough the morning. There is a mid and upper- level closed low over south-central Canada with trough axis extending into southern Iowa. Eventually this will push upper-level cloud cover across the region today, but overall forcing would be weak given the surface anticyclone moving through, leading to a dry forecast for Wednesday. High temperatures today will generally be in the 60s across the region.

High pressure will move east-southeast throughout the day on Thursday. Mid-level northerly flow with the passing trough axis north of the area will push a subtle cold front southward and increase convergence throughout the day. This will introduce chances for light rain shower activity Thursday afternoon and evening, especially for western and northern Missouri. Rainfall amounts range from just a few hundredths to just a couple of tenths of an inch. A few CAMs depict a few hundred J/kg of MUCAPE may be present ahead of the boundary, which could result in a few weak, non-severe rumbles of thunder as this passes through.This line should pass through the forecast area by midnight Thursday Night. Temperatures in the mid to upper 30s Thursday night into Friday are possible, which may lead to some frost for areas north of Hwy. 36.

Mid and upper-level closed-low system moves eastward starting Friday, and will push another surface anticyclone into the forecast area that will keep this weekend dry. Temperatures will remain in the mid to upper 60s Friday and Saturday with weak northerly flow, but should start to see WAA kick in on Sunday, boosting temperatures into the 70s and will continue through the start of the work week. Additional rain shower chances and storm activity will occur with a few short-wave perturbations that will move across the area.

VFR conditions expected to prevail across the sites through the period. Initially, around SCT030 decks will be seen across the sites, but should gradually subside as drier air continues to gradually filter in with the surface high. Otherwise, N/NW winds to around 10 kts too gradually ease, going variable around or after 00z and through the overnight. SW to W winds establish late in the period as well as increasing mid-level cloud cover.
