Warmer conditions continue with highs in the 50s mid-week

CHICAGO (CBS)-- Temperatures in the 40s and 50s are here to stay for the week, with near-record temperatures possible on Thursday and Friday. 

Monday's highs will be near 41 degrees with mostly cloudy skies. 

The first 9 to 10 days of February may be one of the warmest, if not the warmest, on record. That pattern is expected to change after Feb.10 to more-seasonable to colder-than-normal temperatures, according to the National Weather Service. 
 

A Dense Fog Advisory was in effect for far northeast Illinois until 10 a.m. This includes far northern Cook County. Fog could freeze, leading to slick roadways. 

A warming trend continues this week, with showers late in the week. Temperatures will climb to near 60 degrees by Thursday.
