No White Christmas this year, sorry snow lovers! Historically, Chicago has about a 41% chance of seeing a White Christmas. However, if we look at the most recent 30 year data set (1991-2020) that chance drops to 34%. The last time Chicago had a White Christmas was 2022. #ilwx
Yesterday was the winter solstice, the shortest day (and longest night) of the year. Now, the days will start getting a little longer! Here's a look at how much daylight we gain each day this week.
Winter weather may impact travel this evening and again WED AM. Rain may briefly overlap with freezing pavement, potentially causing slick travel conditions early evening (see inset map). The WED AM commute could also be impacted by wind whipped snow showers/squalls. #ILwx#INwx
