Agree, now within 5-6 days instead of 7-10. Also, it looks like there could be a bit of snowpack in the source region (Upper Midwest), which is noteworthy this time of year. If all of this comes together, areas here or nearby could be close to record cold.
Probably getting ahead of myself again ...but here are some records that *could* be in jeopardy:
Madison: Record low 9 on 11/11 (2017), 7 on 11/12 (1979). Record low max 23 on 11/11 (1894).
Rockford: Record low 14 on 11/10 (2017), 10 on 11/11 (1926). Record low max 29 on 11/10 (1933), 26 on 11/11 (1986), 27 on 11/12 (1940).
ORD: Record low 18 on 11/10 (2017), 15 on 11/11 (1950). Record low max 28 on each of 11/10 (1926), 11/11 (1894), 11/12 (1995).
