We should experience quite a variety of weather in the week ahead.
By Monday night conditions will become more unstable with strengthening winds and increased low-level moisture leading to the development of showers and possible thunderstorms. For the second straight night temperatures will slowly rise Monday night, so that 50-degree temperatures could greet residents to the start the day Tuesday.
Showers and thunderstorm downpours with even the possibility of severe storms could occur during the day Tuesday – as temperatures threaten the 59-degree record high set 99 years ago in 1914.
One to two-inch rainfall on top of frozen ground could result in significant runoff, and the warm temperatures could melt ice on the rivers creating ice jams – all resulting in high flood potential.
Temperatures will fall sharply Tuesday night after the cold frontal passage as strong northwest winds usher in the leading edge of a southward-moving Arctic high pressure air mass. Chicago will finds itself deeper and deeper into the cold air as the Arctic high pressure settles farther south the latter half of the workweek.
Highs in the teens and sub-zero wind chills can be expected here next Thursday and Friday.
