Indystorm Posted December 13, 2016 Share Posted December 13, 2016 Latest forecast says Indpls northeastward could get one to three inches of snow tomorrow a.m. as arctic front merges with upper wave. Would be nice to see some snow on the ground. Link to comment Share on other sites More sharing options...

cyclone77 Posted December 13, 2016 Share Posted December 13, 2016 Temp at MLI was 11 at 7pm, and shot back up to 24 by 11pm. Pretty impressive surge of warm advection ahead of this next cold front. Link to comment Share on other sites More sharing options...
Chicago Storm Posted December 13, 2016 Share Posted December 13, 2016 The focus for the overnight minor snow seems to have shifted a bit south.Not as much either. Max around 1-1.5" in the main narrow axis now most likely. Link to comment Share on other sites More sharing options...
Indystorm Posted December 13, 2016 Share Posted December 13, 2016 Nice to see our first extensive snowfall of the season here in Central IN. Snowing moderately with 1-3" plus expected across a fairly wide area. Link to comment Share on other sites More sharing options...
cyclone77 Posted December 13, 2016 Share Posted December 13, 2016 Nice roller coaster action with the temps last night/this morning. Dipped to 11 early eve, rose up to 21 a little after 2am, and have now dropped back down to 8 lol. Link to comment Share on other sites More sharing options...

Indystorm Posted December 13, 2016 Share Posted December 13, 2016 IND NWS officially up to 3.9" as of 1:10 p.m. ET.. looks lovely but a lot of auto crashes, slide offs, and back ups for the first snow of the season here Link to comment Share on other sites More sharing options...

Hoosier Posted December 13, 2016 Share Posted December 13, 2016 Not an unusual sight but you can really see where the snow free zone is, and also where the Chicago metro area is on this visible satellite image with the ring of darker color Link to comment Share on other sites More sharing options...
Chinook Posted December 13, 2016 Share Posted December 13, 2016 So do you think the northern Illinois snow-covered area will get to the minus teens or minus 20s next Monday? The 12z GFS now has -25 near Peru IL on Monday. Gee, I'm glad I am not driving I-80 from Cheyenne to Toledo this Christmastime!!! It'll be an arctic wasteland.

I could see -10 or so...but even that assumes the snow cover remains fresh, i.e. little to no rain & warmth with the upcoming system. The airmass itself doesn't look too impressive; it's more of a radiational cooling situation. Time will tell! Link to comment Share on other sites More sharing options...

Pretty impressive high being progged over N IL...around 1045 mb which is toward the upper end of what we get around here. But timing will be crucial as to whether it can park itself overhead or close enough for a night. Link to comment Share on other sites More sharing options...

Some of the temps the various models have been spitting out lately are pretty eye popping to be sure. Link to comment Share on other sites More sharing options...
RCNYILWX Posted December 14, 2016 Share Posted December 14, 2016 At this rate, them or Aurora might make a run at the state record later this weekend/early week. I'm only half kidding.With how temperatures performed tonight at ARR and RPJ, I'm pretty confident that they'll free fall to 10-15 below Thursday evening before the high shifts southeast and some clouds move in. That means all bets are off for Sunday night if we do get a 1040-1045 mb high overhead at the right time to optimize radiational cooling. The 12z Euro ensemble was showing ridiculous stuff even at ORD for Monday morning, an ensemble mean of 18 below with a huge majority of the members sub 10 below.

I think you have to go back to 1/16/09 for the last time that ORD hit -18. I went back and looked at the reanalysis images from that day. The airmass aloft back then looks colder than what's currently progged for Sunday night, but the surface high is of similar strength. Link to comment Share on other sites More sharing options...

The airmass aloft back then looks colder than what's currently progged for Sunday night, but the surface high is of similar strength.It will definitely come down to clear skies and the surface high being positioned to maximize the cooling. Interesting to note that the most recent runs of the Euro and GFS have not backed off on the magnitude of the cold. Simply for climatology, would hedge against it being quite that extreme, but if we do get optimal conditions and a net gain in snow cover leading into it, could be one of the more notable cold nights in December in the 2000s.

Chambana Posted December 14, 2016 Share Posted December 14, 2016 It's just amazing what a fresh 1" of powder can do to a cold airmass, was forecasted to bottom out at 13, but with calm winds, clear skies, and a measly 1" of snow, we bottomed out at 4 degrees.

beavis1729 Posted December 14, 2016 Share Posted December 14, 2016 Agree with everything above; 12z GFS continues to show a 1044 mb high overhead Monday morning. Record lows for 12/19 are -14 at ORD and -21 at RFD, both set in 1983. Those will be very tough to beat...but merely challenging records from the frigid December of 1983 is pretty impressive. Also, RFD may set a record low max tomorrow (12/15). Current record is 9, set in 1932. Link to comment Share on other sites More sharing options...
