Locally dense fog possible late Christmas night

 


Merry Christmas! While we didn't see much sunshine Christmas Day temperatures were still rather mild, warming into the upper 30s and low 40s. There was a bit of a breeze during the afternoon and that kept a little bit of a chill in the air, but temperatures did manage to warm nearly 10 degrees above average.

Cloud cover will be a plenty through the night as an area of low-pressure moves in from the west. It's not an overly strong low, but enough to bring a few light rain showers to northern Illinois and southern Wisconsin around Midnight. Rainfall totals will add up to just a few hundredths of an inch, up to a couple tenths of an inch by Friday morning.

As the showers move out early Friday morning, areas of dense fog will be possible for parts of the Stateline. Dense fog has developed to the south in central Illinois and out west in Iowa. As winds turn light and dew point temperatures climb the air mass will have plenty of moisture. It may not be significantly widespread but if the fog does develop visibility could fall under a mile for a few locations early Friday. So, if you're up early know that there could be some fog that may impact the morning drive. Cloud cover will remain in an abundance Friday afternoon, but despite that temperatures are likely to warm into the mid and upper 40s. Winds will be a little breezy from time to time, gusting close to 15 mph into the afternoon. Dense fog will once again be possible late Friday night into Saturday morning.
