RCNYILWX Posted January 24, 2019 Share Posted January 24, 2019 The 06z GFS took the cake for most extreme solution for cold here. -41 at 850 at 12z Wednesday, with 500 mb heights touching 489 in far northeast IL and 1000-500 thicknesses in the 470s. We're at the point where moderation of what's being modeled will still give -30 or so at 850. Noon 2m temps over northern IL on Wednesday in the low-mid -20s on the 06z GFS, just incredible stuff. 1 Link to comment Share on other sites More sharing options...
MNstorms Posted January 24, 2019 Author Share Posted January 24, 2019 First Wind Chill Advisory of the season for me. Wind chill of -35F tonight. It'll be nothing compared to next week. Link to comment Share on other sites More sharing options...

beavis1729 Posted January 24, 2019 Share Posted January 24, 2019 Records in play for Chicago. Note some of the data prior to 1928 may be a bit off, as I only did a quick scan of ORD/MDW official data and LOT record pages.

Chambana Posted January 24, 2019 Share Posted January 24, 2019 GFS windchill output has windchills approaching -70 in western Minnesota next week. -55 around Chicago. This definitely has the potential to exceed January 2014. Link to comment Share on other sites More sharing options...
Sciascia Posted January 24, 2019 Share Posted January 24, 2019 GFS showing -34 in Chicago on Thursday. -34 AIR TEMPERATURE. Holy balls. Might have to seriously consider just staying home that day from work if it verifies. Idk how stores would be able to even justify opening when it’s life-threatening cold. 1 Link to comment Share on other sites More sharing options...

Hoosier Posted January 24, 2019 Share Posted January 24, 2019 I agree that the all-time record for Chicago could be in play IF these runs are generally right about the airmass aloft. I think it would have a better chance to happen in a setup like this, in which it's insanely cold aloft and more advective driven cold vs a warmer setup aloft that is heavily reliant on radiational cooling. 1 Link to comment Share on other sites More sharing options...

Agree completely...and it will also help if the Sunday-Monday clipper adds some fresh snow cover to help offset any potential UHI effects. Even if ORD "only" hits -20, it would be the coldest since January 1994 (Feb 1996 hit -19 at ORD, I believe). 12z GFS continues the insanity...only 6 days out now: Link to comment Share on other sites More sharing options...

Will be very interesting to watch this unfold. I consider coldest temp, hottest temp and biggest snowstorm for a given location as sort of the holy trinity of weather records.

The 12z GFS has -26 for Bowling Green and about -24 for Toledo Express Airport. Both of these are colder than the all-time record lows: -22 at Bowling Green and -20 at Toledo. 2 Link to comment Share on other sites More sharing options...

Hoosier Posted January 24, 2019 Share Posted January 24, 2019 I have trouble with wunderground these days so maybe somebody can check, but didn't the -27 at Chicago on 1/20/85 occur at like 9 am? So it doesn't necessarily have to be a nighttime min temp if you bring the coldest pool of air overhead during a different time of day. 1 Link to comment Share on other sites More sharing options...

Chicago Storm Posted January 24, 2019 Share Posted January 24, 2019 HRRR has mid -10's for lows at ORD tonight and tomorrow night. Not records, but could rival the extreme cold of January 2014. Lowest during that period was -16 at ORD. Link to comment Share on other sites More sharing options...

Track of potent upstream amplifying wave late Sun predicated on how quickly deep low south of James Bay ejects out ahead of sewd peeling PV dropping through cntrl Canada. Regardless of specific solution track, intense warm advection wing expected to emanate ese of deepening cyclone as leading strong moisture push off the Gomex hits eroding swrn flank of arctic wedge. 12Z deterministic consensus shifted south again and holds retreating arctic wedge in longer yet still some threat exists for a mix far s/se. Wrn OH valley sourced pivot point would portent a prolonged duration of snow as deformation zone overlaps leading warm advection zone and likely hefty snow amounts given sharp baroclinic zone in place. Nevertheless strong flow inadvance and behind this system promise a mess with the addition of considerable blowing/drifting snow. Thereafter a brutishly cold airmass entrenched through nrn Canada will blast south commensurate with PV swing through Michigan. Many long standing records will no doubt fall and threaten all-time cold records as raw 2m guidance sits in unseen territory across the nrn OH valley.

Chambana Posted January 24, 2019 Share Posted January 24, 2019 I really need the clipper on Monday to materialize if we want to maximize the potential of this possible historic cold wave. Yesterday’s heavy rainfall and temps of 39 degrees put a huge dent in our snowpack, in fact a lot of places have 1” or less on the ground. Link to comment Share on other sites More sharing options...
