Kansas City’s larger portion is on the Missouri side of the river, but many of the large suburbs exist on the Kansas side. None of this really helps with our forecast, or dictates a different climate between the towns.

At 253PM, CT, Kansas city was reporting mostly cloudy skies with a temperature of 49 degrees. West-northwest winds were blustery and bringing temperatures down a bit, but without the clouds that are being seen further to the north, it’s still a quite bearable end to the year.
The clouds and whatnot seen in the Great Lakes is a western lobe of a broader trough on the east coast. The cooler air mass is going to continue sinking further south, even without a particular threat for precipitation. This will drive an inactive cold front through Kansas City overnight, leading to a cooler day tomorrow before a stout, clear area of high pressure moves into the middle of the country.

Those lows in the V-W forecast are a bit lower because we used the information out of the Kansas City airport, which is well outside the city center. Check out the forecast for KCTV-5. There is a distinct focus on the Chiefs football game this weekend.
