We’ve made it to the weekend! We’re going to be headed for Saint Louis for the forecast this weekend. There are a bunch of warnings blanketing Missouri, but this time, they are Red Flag warnings. That should tell you something about what you can expect.
At 251PM, CT, Saint Louis was reporting a temperature of 70 degrees with overcast skies and a brisk southwest wind. A strong ridge is building into the center of the country, and at this point, St. Louis is on the right side of the local warm front. An embedded wave sliding into the Plains will tap into some of the moist Gulf Air tonight into tomorrow morning, which will result in cooler temperatures for the weekend, as well as a bit of overcast.
A high amplitude and tilted trough is pointed towards the Desert Southwest, allowing for the warm southerly flow, but also will set up a favorable environment for cyclogenesis in the northern Plains. That feature will hook up with the disturbance gliding southeast of Saint Louis tonight, and encourage the overcast to move on. Colder air will rotate around the developing system in northern Plains, and cooler air will spill back south into the mid-Mississippi Valley to conclude the weekend.

Things are going to cool off pretty quickly in the Gateway City, but all things considered, that’s not a bad forecast for the middle of February.
All outlets with hourly forecasts through the weekend have non-standard days for Sunday, setting up for a chilly beginning to the week. The field of clouds lifting from the south is all very near the surface. You can really only make them out over north central Arkansas when looking at the national infrared.
