/18Z TAFS THROUGH 00Z TUESDAY/... Issued at 1130 AM CST Sun Nov 15 2026
The main and only concern this TAF period will once again be the development of river valley steam and radiation fog Monday morning given only slight changes to current weather pattern. KSUS and KCPS are most favored to see impacts from fog. Otherwise, light variable to southeasterly winds will prevail.
