(10:30PM - 2/24/19) A new series of disturbances will bring the chance of snow to portions of the state from Monday night through Wednesday afternoon.
A combination of multiple disturbances moving through the region, warm air advection and frontogenesis...will bring the chance for snow to portions of Northern Illinois Monday night through Wednesday afternoon. While light snows will be possible during the whole period, the most organized snows will be late Monday night through Tuesday morning, and then once again Tuesday afternoon through Wednesday morning. This will be a minor event overall, with accumulations ranging from a dusting closer to I-80, to 1-3" from around I-88 to the Illinois/Wisconsin border.
Additionally, a bit of freezing drizzle may be possible across portions of Northern and Central Illinois, between roughly I-88 and I-74. This will be possible Tuesday night into Wednesday afternoon.
Below is our TAM snowfall forecast for this event.
