Dense fog drapes the area this morning. A Dense Fog Advisory for all of Southeast Michigan is set to expire at noon as we replace fog with rain showers.
Why does this fog seem never-ending? Well, inversion fog forms when a layer of cold air is trapped near the ground under a layer of warmer air (a temperature inversion). This typically is longer lasting as the upside-down atmospheric condition prevents air mixing, trapping moisture close to the surface, which can last for days. It doesn’t help when we have melting snow and rain showers which adds to the moisture content close to the surface.
Mild temperatures persist today as highs will reach the upper 40s. We have a couple rounds of rain on tap. We could see rain roll in by late morning and last through the afternoon. We will likely get a break this evening before another round arrives just before midnight.
We will reach our high temperature close to 50 on Friday by late morning with falling temperatures throughout the day. We have a snow chance by Friday afternoon or evening, mainly to our north. Back into the 30s this weekend. We then fall below freezing next week as high will be on either side of 30 on Monday and Tuesday with lows in the teens.
