Marine Weather and Tide Forecast for Lansing, KS

DISCUSSION
Issued at 229 AM CST Fri Jan 30 2026

Water vapor imagery from early this morning shows a robust shortwave trough diving southward through MN. This system is moisture-starved with limited lift as it is moving through the forecast area later today. None-the-less, we should see about 10,000 feet of saturation that is nearly entirely in the dendritic growth zone, with cloud bases as low as 1500 to 2500 feet. Given that, it looks like flurries are possible across most of the forecast area, with the most-likely area being eastern KS and western MO late in the morning- early in the afternoon, spreading east during the afternoon to evening hours. There is at best a 10% chance for any accumulating snow (>0.1") in eastern KS and western MO. Most of the forecast is less than 5% for anything to accumulate.

That shortwave trough will help to push a cold front southward through the area, will bring another shot of bitterly cold air.
By Saturday morning, a strong 1040+ mb high settles over Kansas as temperatures drop below zero across eastern KS and Missouri.
Our area may be spared the coldest temperatures with the high centered to our west and but we'll still see sheltered and drainage areas across the area with well below zero low temperatures Saturday morning. With winds diminishing as the surface high moves in, apparent temperatures fall to as cold as -14 across northwestern MO and eastern KS. For now, will hold off on any Cold Weather Headlines.

There is another chance for light snow Saturday night into Sunday.
Another shortwave trough will move through the area Saturday night through Sunday afternoon. This system has slightly better moisture than the Friday system, though still very limited. With deeper saturation and some isentropic ascent, flurries to light snow is possible The highest probability for accumulating snow (>0.1") is across northern MO. Though the entire forecast area does have some probability of this occurring. When bumping totals to 1", probabilities fall significantly, with just a 5-10% chance for an inch of snow north of Highway 136. Overall, little if any snow is expected, but there may be a dusting across northern MO.

Tuesday into Wednesday next week, a stronger shortwave will move across the middle of the country. Much better moisture will advect north into the region, ahead of the shortwave trough. This will bring a chance of precipitation to the area. It will depend on the timing of the precipitation, but there is low probability (5-10%), for freezing rain and a 15-50% chance for accumulating snow in a gradient from southwest to northeast. It's also possible that when the precipitation is falling, the air temperatures, and temperatures aloft, are above freezing. The one caveat here is if that will be enough to warm ground temperatures, given the prolonged well below normal temperatures we've experienced recently. If ground temperatures are slow to warm above freezing, freezing rain is possible. These timing and temperature details will continue to fluctuate through the weekend into early next week. So this system will need to be watched close for the possibility of mixed/ freezing precipitation.

AVIATION /18Z TAFS THROUGH 18Z SATURDAY/
Issued at 1128 AM CST Fri Jan 30 2026

Not quite a full VFR period, but not too far off either. An area of MVFR ceilings continues to gradually drop southward out of Iowa, and appears poised to be high-MVFR across the TAF sites this afternoon into evening before clearing back out. Given upstream obs and trends, most mentions of BKN/OVC025 or 030.
Winds will periodically gust to the low 20s kts this afternoon/early evening as well before easing and shifting from the N to NW. As the aforementioned MVFR cigs drop southward, some light flurries may be experienced, but given expectation for P6SM with or without, have opted against any prevailing mentions.
