Look, I get the NWS focus on public safety…but it’s a bit much to obsess over an inch of snow with temps in the teens. It’s winter - these things are supposed to happen. It’s really not a big deal. Of course, if one wants to argue the opposite viewpoint, you’re basically saying that Chicago doesn’t have winter…and that any snow event is extraordinary. I actually happen to agree that Chicago doesn’t really have winter (we have wintry periods, but not winter). But pick one viewpoint or the other; you can’t have it both ways. Another component is the stupidity of the average Joe. If it’s slippery, drive slowly and keep your distance. The NWS shouldn’t need to watch over you.

Brownsville dropped to 27F today, and the dewpoint is currently 7F. Not bad for the southern tip of TX. This is their coldest December temp in more than three decades. It was 16F exactly 33 years ago, on 12/23/1989...which is their coldest December temp on record by far. All-time low is 12F during the infamous February 1899 cold wave.

From NWS Denver...although these are only the record calendar day, 2-day, and 3-day temp changes...as opposed to hours. Yesterday made the list as the 3rd largest calendar day temp change (51 to -10), and yesterday & today was the 2nd largest 2-day temp change (51 to -24). https://www.weather.gov/bou/denvertemperaturechanges

Looks like Denver (officially at DIA) hit -24 this morning. That's the 3rd coldest daily low temp on record in December: -25 on 12/22/1990 -25 on 12/24/1876 All-time coldest is -29 on 1/9/1875. Also, Denver's coldest daily max temp on record in December is -8 on 12/21/1983 (high -8, low -21). There's a slight chance of this being broken or tied today, but unfortunately I think it will warm up to around -5.

Pretty brutal conditions in Williston ND right now. Temp -23 with a sustained 25 mph NW wind, wind chill -55. Edit: even colder in Bowman ND, temp -24, NW wind 39 mph, wind chill -62. Wow…

NWS Great Falls mentioned in their AFD that valley locations could drop to -40 or colder under the high pressure, and that many automated thermometers may not be accurate since they are only calibrated to -40.

While we drown our sorrows over the recent model snowfall trends, here's the NWS Great Falls AFD for posterity. At least it will be cold somewhere. Wednesday night through Thursday...Record breaking temperatures are expected. Some locations will be colder than 40 below zero. It is possible some of the coldest valleys could see air temperatures colder than 50 or 60 below, as record surface high pressure approaches the region. (The all time record cold for the lower 48 states was at Roger`s Pass, with a temperature of 70 below.) Current temperatures in northern Canada are 50 to 60 below, thus these temperatures are possible. These records will be dependent on skies becoming clear, and any cloud cover will limit how cold it gets. Overall, current forecast lows for Thursday morning were adjusted a bit colder than the NBM and might need to be adjusted even colder over the next day or so should sky cover look to become more clear. Also, a wind chill advisory will be needed for portions of Southwest MT Thursday night into Friday morning. Note...be aware that some temperature sensors are only capable of measuring temperatures to near 40 below. Thus it could actually be colder than what is currently reported for some weather stations. The NWS/FAA temperature sensor can report temperature values down to 80 below.

Nice - should drop to around 8-10F tonight here, also the coldest of the season. Will be a bit chilly in northeast MT over the next 5 days...here's the point for the town of Plentywood. High of -20 on Wed. Tonight Snow likely, mainly after 4am. Mostly cloudy, with a low around -15. Wind chill values between -30 and -35. East wind 11 to 13 mph. Chance of precipitation is 60%. New snow accumulation of less than a half inch possible. Monday Snow likely, mainly before 11am. Mostly cloudy and cold, with a high near -7. Wind chill values between -25 and -35. East wind 9 to 13 mph becoming west northwest in the afternoon. Chance of precipitation is 60%. New snow accumulation of less than one inch possible. Monday Night Partly cloudy, with a low around -23. Wind chill values between -40 and -50. West northwest wind 13 to 15 mph, with gusts as high as 20 mph. Tuesday Mostly sunny and cold, with a high near -18. West northwest wind 14 to 16 mph, with gusts as high as 21 mph. Tuesday Night A 20 percent chance of snow after 11pm. Partly cloudy, with a low around -29. West northwest wind around 14 mph. Wednesday A 20 percent chance of snow before 11am. Partly sunny and cold, with a high near -20. Northwest wind 14 to 18 mph, with gusts as high as 23 mph. Wednesday Night Mostly cloudy, with a low around -26. Northwest wind around 18 mph, with gusts as high as 24 mph. Thursday Mostly sunny and cold, with a high near -19. Northwest wind around 18 mph, with gusts as high as 28 mph. Thursday Night Partly cloudy, with a low around -30. Northwest wind 10 to 15 mph becoming west southwest after midnight. Winds could gust as high as 21 mph. Friday A 20 percent chance of snow. Partly sunny and cold, with a high near -8. South southeast wind 10 to 16 mph. Friday Night A slight chance of snow. Mostly cloudy, with a low around -15.

Come on...this is completely uncalled for. What is the point of saying something like this? Oh wait...I forgot that the American culture thrives on putting everyone else down as much as possible in order to feel better about ourselves.

Yeah...and at hour 120, there's a 1068 mb high in MT. Would be an all-time record for the lower 48. Oh, and it's a bit chilly under that high too...around -40F.

I mean the Lower 48 record high pressure - 1064 mb in Miles City, MT on 12/24/1983.

Yeah, and by a lot. Current record is 1064 mb on 12/24/1983.

And the 18z GFS ups the ante, getting into the realm of the ridiculous. 1073mb in MT…and “only” at hour 210.

The Euro shows the mother of all troughs in the West toward the end of the run - it's really incredible. Not enough hot dogs to show the true magnitude. Near 20F in San Francisco and 0F in Seattle. And an insane temp gradient.

Would be a tad windy...just your everyday 73mb pressure gradient between IN and WY.

Yikes...that would shatter the Lower 48 high pressure record (1064mb in Miles City, MT 12/24/1983).

1064mb in Miles City, MT on 12/24/1983. Would be a tad windy on that panel, with a 73mb pressure gradient between IN and WY.

Anyone know where Hoosier is? Haven't seen him post lately.

Day 10 Euro shows a 1070mb high in Alberta...that's crazy. Of course, it's only one run of an op model 10 days out. The Lower 48 record is 1064mb in Miles City, MT on 12/24/1983.

Wow, a 1070mb high in Alberta. I know it's a Day 10 Euro prog...but that's insane. For reference, the Lower 48 record is 1064mb in Miles City, MT on 12/24/1983.

You'd think this would be a great look in the MW/GL, given the mean trough being in a decent spot (a bit west) to avoid storms being suppressed. But it seems like no Day 8+ fantasy storms are showing up on the op runs yet. Or, my interpretation of the map could be wrong...

12/24/1983 was one of the coldest days on record in Chicago. High -11, low -25.

You rang? George's post got 16 hot dogs - could be a new record! All in good fun.
