Marine Weather and Tide Forecast for De Soto, KS

DISCUSSION
Issued at 303 PM CST Fri Nov 6 2026

Much of the late morning and early afternoon has been dreary for northwestern MO/northeastern KS with low clouds and patchy light drizzle. Low clouds have begun to clear across far northeastern MO with the advection of dry low-level air from the north, which will allow clear skies for areas generally east of US-65 going into the evening. As surface high pressure slides to the southeast during the evening, a layer of dense, cold air will settle over much of MO and eastern KS overnight. Winds will also calm closer to the center of high pressure, which will inhibit the ability of low clouds to mix out further to the west and south overnight. Current frost/freeze headlines still reflect general expectations for temperature trends across the area, but cloud cover still remains the focus for any deviations in the temperature forecast overnight... For areas where skies remain clear overnight and winds remain light/calm, enhanced radiational cooling will contribute to temperatures falling at/below freezing overnight. However, for areas that remain under dense cloud cover, temperatures will trend slightly warmer than freezing overnight.

Surface high pressure will continue sliding off towards the southeast through the day on Saturday, with temperatures beginning to warm under weak WAA in the low levels to the high 60s/low 70s by early next week. Weak ascent in the mid/upper levels could contribute to lingering cloud cover during the day Saturday, but otherwise the synoptic pattern becomes relatively benign under west/northwest flow in the upper levels with quasi-zonal flow, keeping the forecast warm and dry for the early week. Synoptic guidance continues to indicate the passage of a mid-level trough to the northeast as mid-level ridging builds over the western CONUS by midweek next week, but some disagreement remains on precipitation placement/trough passage, leaving some uncertainty on forecast details around that timeframe. However, with the passage of the trough, winds shifting out of the north will introduce cooler, drier air by the end of the forecast period, cooling temperatures down to the low 60s/upper 50s.

AVIATION /06Z TAFS THROUGH 06Z SUNDAY/
Issued at 1053 PM CST Fri Nov 6 2026

Our stratus deck will remain over the TAF site areas throughout the overnight and morning hours, with ceilings approaching to just under 1000ft. As a result, the TAF sites will be in the low MVFR to IFR range until mid morning on Saturday. Throughout Saturday morning, ceilings will increase and cloud cover will begin to diminish, which will result in the TAF sites to return to VFR. Winds will be light and variable through the overnight hours, with speeds increasing to around 3-5kts from the SW beginning Saturday morning.
