Jan 18-25 Cold Wave

[Geoboy645]

What was originally looking like a pretty standard cold wave for mid January has now become a potentially very significant cold wave for the region. Model runs are showing sub zero highs for at least the northern parts of the subforum on Friday and potentially Saturday. And some runs like the most recent GFS have daytime highs on the level of the 94,96, and 19 cold waves at least N of the IL-WI border which is extremely impressive without widespread deep snow cover. We have already had sub -30 wind chills and sub -5 daytime temps here today, and if we don't cross 20 on Wednesday we may have at least 10 days straight of sub 20 highs.

Fingers crossed the cold moderates a little a bit as we get closer. Friday/Saturday looks nasty across Chicagoland as of now.

Don't like extreme cold without snow cover.  Frost goes deeeeep.

Nice summary. Does anyone know of a reliable current snow cover map for the Midwest? 

Dropped to -3F here this morning, up to 5F at noon.

I forgot how insane 2019 was around here. Daytime readings double-digits <0

Plus 20mph winds

-10 for a high on Friday and -20 for lows on Friday and Saturday in reach for MN and WI. Would only be the third such high temp and 10th such low temp since 1996 in MSP. Interestingly last year we had a -19 morning with only 1" of snow on the ground. The clippers of the past/upcoming week should help this time around.

Looked through at the Madison WI records which surprised me, it looks to be only their 8th (and possibly 9th) subzero high temperature since 1996 and first time since then with back-to-back days high temp below zero. And there have only been three days with a low of -20 or less in the same period.

Gonna be a while before we surpass the cold and wind chill of 2019 though.

Overnight lows in the single digits here at KLIN, with daily highs for the weekend in the low to mid teens.  Seems the big storm that I have been hearing about misses this area completely.
