Marine Weather and Tide Forecast for Merriam, KS

DISCUSSION
Issued at 133 AM CST Sat Nov 7 2026

Broad surface high pressure across the region this morning is expected to shift southeastward today with southwest to northeast flow developing in the near surface layer. This will bring the stratus across eastern KS back into the region today. The stubborn cloud cover and weak flow will keep temperatures cool once again today, and have lowered forecast highs into the low and mid 50s.

Low clouds are are expected to clear the region tonight; however, the southwest flow will remain ahead of a weak boundary approaching from the north. Models are hinting at the potential for patchy fog developing across northern Missouri, but increasing high clouds building south may limit the radiative potential, so for now, have left the mention out of the forecast. With dry airmass, expect temperatures to fall back into the mid 30s across central into eastern Missouri leading to another frosty night.

Expect warmer conditions on Sunday as 925 hpa temperatures warm 8-10 C over Saturday's values. With just high clouds across the region, should be a fairly pleasant fall day.

Weak boundaries associated with systems moving east across Canada are expected to approach every few days; however, broad high pressure across much of the lower 48 are expected to limit their impact. A series of phased waves lead to the development of a deepening trough mid-week across the Great Lakes into the Tennessee Valley. While the precipitation with this system looks to remain east of the area, cooler temperatures are expected Thursday into next weekend are expected with north-northwesterly flow.
Temperatures moderate towards seasonal norms next weekend as trough builds toward the east coast, but with the developing blocking pattern, system may not be in a hurry to move east.

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.
