Initial quiet conditions with mostly clear skies will make way
to an impending cloud deck seen over western Iowa at TAF
issuance. Associated flight restrictions march northeast
overnight, reaching local counties in northeast Iowa near
26.12Z. A quick drop to IFR is expected after MVFR becomes
realized. The southwest to northeasterly trajectory brings MVFR
ceilings along the Mississippi River Valley by the early
afternoon.

Thunder potential remains in flux. While confidence within the
local area is moderate-high, nailing down the exact location
remains a challenge. Therefore, given the 18 hour forecast
window, have omitted any mention for thunder at 26.06Z TAF.

Ongoing Low Level Wind Shear expected to continue into the early
morning hours at KLSE. Models would suggest another bout
returning tonight, as surface winds calm and the low level jet
persists. Timing of frontal features and associated jet will
aide coming forecasts in subsequent LLWS potential.
