Locally Dense Fog Possible Sunday Night & Monday Morning

High levels of moisture in the atmosphere will lead to locally dense fog Sunday night and early Monday morning.  Dense fog remains along the lake shores of Lake Michigan, but have now pushed a little further inland and over northern Illinois. 


Temperatures are currently in the low 60's, but so are dew point temperatures.  This means the atmosphere is nearly saturated, which is why fog is beginning to develop.  Thankfully rain won't be much of an issue, but you may need to give yourself a little extra time in the morning with the developing fog.
