This image is the 1915 UTC visible satellite observations. We can see two main areas of clouds in the middle part of the country, both associated with precipitation. The northern cloud group is dropping snow over the plains. We could see some snow showers tonight from the same system here in Lafayette. The southern portion of the state will continue to be impacted by the other system, which is currently dropping rain. Later tonight, some parts of the southern half of the state could see rain or a mix of rain and snow.
After this system moves out, high pressure will dominate, and skies will be mostly clear. Tomorrow and Wednesday should clear skies, light winds, and highs in the upper 30's tomorrow, and lower 40's Wednesday. This image is for 12Z Wednesday, and shows most of the country being dominated by high pressure, with little precipitation over the lower 48.
