Good Saturday afternoon. I’m sure this is not an update that will excite you but its on obvious trend we need to mention for the forecast tonight. Both of my hi-res RPM and RAP models are indicating freezing fog develops tonight across the area. While we cannot pinpoint where it develops because that is not possible we can tell you the atmosphere is conducive for fog to develop as we have a warm south wind blowing in over the snow on the ground tonight. Model soundings indicate the atmosphere is saturated at the lowest levels Sunday morning which also would indicate freezing fog/mist concerns. This is an advection fog type scenario due to the warmer air at the surface working in. Here are the model ideas below:
I will say the “strongest signal” I see is coming just north and west of Indy via the looks of a skew-t out of Lafayette Sunday morning at 7am:
The dark grays indicate 0 visibility.
The dark reds indicate 0 visibility.
Right now the models do not take us above freezing tomorrow and would suggest clouds hang around most of the day. I would make sure lots are monitored and or salt is down to prevent a sneak attack on us Sunday morning. If you have questions please feel free to reach out to me. Here are forecast highs Sunday. Ill be around for questions. M.
