Trapped under “Dirty High” centered over far southwestern Indiana, with southwest winds, dense fog deck from Kansas, Missouri, Oklahoma & Texas has moved eastward. In parts of our area, visibility is down to 0.25 mile.
Even with a brisk wind, this inversion is so strong is basically trapped the stratus all the way down to ground level.
Recently, a very large hole has developed in the stratus/fog in eastern Missouri/southern Illinois as some downsloping from the Ozarks has scoured it out. Also little upper low in Texas/Arkansas has led to a perturbation of mixing downstream, which has helped mix out some the fog/stratus in that area, too.
Hopefully, a domino effect will take place & stratus/fog will get chewed up into our area. I am hopeful of that, but the model data says otherwise.
Temperatures will struggle today, unless we can get the sun out. It is only 32 at 12:36 p.m. at the station.
