Accumulating snow on the way Thursday into Thursday night, slushy 2-4 inch totals possible from I-80 north, locally more in counties adjacent to Wisconsin line - thundersnow not out of the question
This season, which has produced the most frequent measurable snowfall across the Chicago area in 27 years, is to become even snowier. An accumulating late season snow is on the way again Thursday! A vigorous eastbound disturbance, responsible for occasionally heavy snowfall which has trimmed visibilities to a half mile or less at times as it's moved across Iowa overnight, brings sleet and snow to Chicago, which is to switch to occasionally heavy wet snow here by and during the afternoon and evening. The lift this system is to generate is consistent with that known to produce embedded thundersnow -- so thunder and lightning with the snowfall isn't out of the question in portions of the Chicago metro area. The heaviest snowfall is to occur primarily north of I-80. General 2-4” totals are expected — with locally heavier totals not out of the question in the counties adjoining and north of the Illinois/Wisconsin state line. A measurable (0.1" or more) snow would make the 2007-08 snow season the most frequently snowy since the record snow season of 1978-79. Measurable snow has fallen 43 times this season, nearly twice last season's 22 measureable snow occurrences and well ahead of the long term average of 26 measurable snows by March 27.
